CSST PRACTICE TESTING V2

Under AHERA, all LEA's must have a management plan in place by which date?

A. July 1989

B. October 1988

C. July 1988

D. October 1989

C. July 1988

The fiber concentration in a work area is measured to be 0.02 f/cc, what is the concentration for a worker wearing a half-face respirator?

A. 0.02 f/cc

B. 0.0005 f/cc

C. 0.001 f/cc

D. 0.002 f/cc

D. 0.002 f/cc

Explanation:

A half-face respirator has an Assigned Protection Factor (APF) of 10. This means the respirator reduces the airborne fiber concentration by a factor of 10.

Formula:

Inside Concentration = Outside Concentration / APF (Assigned Protection Factor)

Inside Concentration = (0.02 f/cc) / 10 = 0.002 f/cc

When must an employer institute a medical surveillance program for workers exposed to asbestos?

A. If they are exposed over the action level for more than 30 days in a year

B. If there are exposed over the permissible exposure limit

C. If they are exposed to any amount in the course of maintenance or custodial activities.

D. If they are exposed over the action limit or wear a respirator.

A. If they are exposed over the action level for more than 30 days in a year

Under the Cal/OSHA regulation, employees must be notified of their personal sampling results by what method?

A. In writing to each individual employee

B. By posting at a central spot in the workplace

C. Both A and B

D. Either A or B is acceptable

D. Either A or B is acceptable

You are monitoring the abatement of all insulation on a mechanical tank which is 8' long and has a 3' diameter in a school. Following the visual inspection, you collect five PCM samples inside the work areas with a sample volume of 3,850 liters each. All of the samples came back less than 0.01 fibers/cc by NIOSH 7400 method, so you cleared the zone. What d you do wrong?

A. Insufficient sample volume

B. Insufficient number of samples for the size of the work area

C. Excess material quantity for this method

D. Nothing wrong

D. Nothing wrong

Explanation:

Under EPA's AHERA regulations (40 CFR Part 763, Subpart E, Appendix A) for asbestos abatement in schools, PCM clearance sampling must follow specific guidelines:

Minimum Number of Samples

For containment areas ≤ 1,000 ft², at least 5 samples are required.

For 1,000-5,000 ft², at least 10 samples are required.

For >5,000 ft², at least 15 samples are required.

Work Area Size Consideration

The mechanical tank's insulation could be considered part of a larger work area, depending on the scope of abatement.

If the containment area exceeded 1,000 ft², then more than five samples were needed.

NIOSH 7400 Method

This method (Phase Contrast Microscopy - PCM) is commonly used for airborne asbestos fiber counting but does not distinguish between asbestos and non-asbestos fibers.

While your results were below the clearance limit (0.01 f/cc), if the area was larger than 1,000 ft², you failed to collect enough samples to meet AHERA clearance requirements.

Asbestos was introduced to the US in large amounts in which of the following time periods?

A. Late 18th century

B. Late 19th century

C. 1930's

D. 1960s

B. Late 19th century

Explanation:

Asbestos began to be widely used in the late 19th century, particularly during the Industrial Revolution, when its heat resistance and durability made it a popular material in construction, shipbuilding, and manufacturing. Its use significantly increased in the 20th century, peaking between the 1930s and 1970s before regulations were introduced due to health concerns.

Asbestos warning signs should be located in which of the following locations in a mechanical room which contains intact, friable asbestos pipe lagging?

A. On the door outside

B. Ever 3' on the pipe insulation

C. On or adjacent to insulation

C. On or adjacent to insulation

At the end of an asbestos abatement activity, equipment is being removed from the zone after decontamination and prior to clearance testing. Where should the equipment be brought out?

A. Through the shower assembly

B. It should be stored in the zone until after clearance

C. The bag-out chamber

D. Through the clean room

C. The bag-out chamber

Explanation:

At the end of an asbestos abatement activity, all equipment must be properly decontaminated and removed from the contaminated area. The bag-out chamber is specifically designed for this purpose. It allows for the safe removal of equipment and waste from the abatement area without contaminating clean areas.

AHERA defines which of the following as asbestos

A. Materials containing greater than one percent asbestos by PLM

B. Materials containing greater than one-tenth of one percent of asbestos by PLM

B. 0.5 to 3.0 liter per minute flow rate

C. 4 to 16 liter per flow rate

D. < 10 liter per minute flow rate

B. 0.5 to 3.0 liter per minute flow rate

Explanation:

OSHA Reference Method:

An air flow rate between 0.5 liter/min and 2.5 liters/min shall be selected for the 25-mm cassette. If the 37-mm cassette is used, an air flow rate between 1 liter/min and 2.5 liters/min shall be selected. Where possible, a sufficient air volume for each air sample shall be collected to yield between 100 and 1,300 fibers per square millimeter on the membrane filter. If a filter darkens in appearance or if loose dust is seen on the filter, a second sample shall be started.

The OSHA Reference Method requires the following minimum number of blanks for 10 samples.

A. 1

B. 2

C. 3

D. 4

B: 2 field blanks

Explanation:

OSHA Reference Method Each set of samples taken will include 10% field blanks or a minimum of 2 field blanks. These blanks must come from the same lot as the filters used for sample collection. The field blank results shall be averaged and subtracted from the analytical results before reporting. A set consists of any sample or group of samples for which an evaluation for this standard must be made. Any samples represented by a field blank having a fiber count in excess of the detection limit of the method being used shall be rejected.

The limit of quantification of the NIOSH 7400 and OSHA Reference Methods is thought to be:

A. 100-1300 Fibers per millimeter squared

B. 0.01 fibers per cubic centimeter

C. 7 fibers per millimeter

D. 100 fibers per millimeter squared

B. 0.01 fibers per cubic centimeter

Explanation:

The limit of quantification (LOQ) for the NIOSH 7400 and OSHA Reference Method for asbestos fiber analysis is typically around 0.01 fibers per cubic centimeter (f/cc). This means that fibers below this concentration cannot be reliably quantified using these methods.

Respirators are not required to be worn in which of the following locations

A. Clean room

B. Equipment room

C. Shower

D. Bag-out chamber

A. Clean room

Which type of asbestos is most common in acoustical applications?

A. Chrysotile

B. Amosite

C. Crocidolite

D. Grunerite

A. Chrysotile

The competent person on an asbestos abatement job must have which of the following training?

A. Three-day AHERA worker training

B. Three-day AHERA building inspector and four-day AHERA worker training

C. Four-day AHERA worker training only

D. Five-day contractor/supervisor training

D. Five-day contractor/supervisor training

Explanation:

Under OSHA and EPA regulations, the competent person for an asbestos abatement job is required to have specialized training, typically a five-day contractor/supervisor training course. This training prepares the individual to oversee the abatement activities, ensuring that the work is conducted safely and in compliance with regulations.

The EPA "land-ban" notice serves what function?

A. Keeps asbestos wastes out of landfills not equipped to handle them

B. Prevents disposal of non-friable asbestos waste in municipal landfills

C. Keeps RCRA waste out of landfills not equipped to handle them

D. All of the above

D. All of the above

Explanation:

The EPA "land-ban" notice was established to ensure that asbestos-containing waste is disposed of in landfills that are specifically equipped to handle hazardous materials, as required under the Resource Conservation and Recovery Act (RCRA). This notice serves to prevent the improper disposal of asbestos waste in regular municipal landfills that may not be able to handle the hazardous material safely.

A. Keeps asbestos wastes out of landfills not equipped to handle them: This is the correct purpose of the land-ban notice. It ensures asbestos is disposed of in landfills with the proper containment and safety measures.

B. Prevents disposal of non-friable asbestos waste in municipal landfills: The land-ban notice applies to all asbestos-containing waste, not just non-friable, but it's more about preventing improper disposal in landfills ill-equipped to handle the material.

C. Keeps RCRA waste out of landfills not equipped to handle them: The land-ban notice specifically addresses asbestos-containing waste, not all RCRA wastes.

D. All of the above: While aspects of these choices are true, A best defines the function of the EPA "land-ban" notice.

A Z-test is used under AHERA when:

A. A TEM clearance fails the 70 structures/mm2 average

B. When a TEM clearance fails and the cause is suspected to be contamination from outside the work area

C. When a PCM clearance fails and using a TEM is considered uneconomical

D. When a perimeter sample exceeds 0.01 f/cc

B. When a TEM clearance fails and the cause is suspected to be contamination from outside

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), a Z-test is typically used in situations where there is a failure in Transmission Electron Microscopy (TEM) clearance and it is suspected that the failure might be due to contamination from outside the work area. The Z-test is used as a statistical method to analyze the data and determine whether the detected contamination is truly related to the abatement process or if external contamination may have affected the results.

A. A TEM clearance fails the 70 structures/mm² average: The Z-test is not specifically used for this scenario; this would typically indicate a clearance failure, but not directly related to a Z-test application.

B. When a TEM clearance fails and the cause is suspected to be contamination from outside the work area: This is the correct context for using a Z-test. It helps determine if contamination from outside the abatement area is influencing the results.

C. When a PCM clearance fails and using a TEM is considered uneconomical: TEM and PCM are different methods for analyzing asbestos samples. A Z-test wouldn't be used just because TEM is deemed uneconomical.

D. When a perimeter sample exceeds 0.01 f/cc: This is an action level, but not a direct application for a Z-test.

You are conducting a survey and come into a room with a single fireproofed beam. The decking is not fireproofed, other than where the overspray from the beams covers it. The flanges of the beam are 6'' wide on each side, for a total width of 12"; the web is 2', and the overspray extends out 18" on either side of the beam. The beam is 25' long. What is the square footage of the fireproofing?

A. 225 square feet

B. 250 square feet

C. 275 square feet

D. 300 square feet

A. 225 square feet

Let's break it down:

The beam has a length of 25 feet.

The flanges of the beam are 6 inches wide on each side, for a total of 12 inches.

The web of the beam is 2 feet (24 inches) wide.

The overspray extends out 18 inches on either side of the beam.

Step 1: Calculate the area of the fireproofing on the flanges.

The flanges are 12 inches wide and 25 feet long. We first convert the width to feet: 12 inches = 1 foot.

Thus, the area of the flanges is:

Area of one flange = width x length= 1ftx25ft= 25SF.

Since there are two flanges, the total of areas of the flanges is:

Total areas of flanges = 25 SFx2=50SF

Step 2: Calculate the area of the fireproofing on the web.

The web of the beam is 2 feet wide and 25 feet long:

Area of web = 2ftx25ft= 50 SF.

Step 3: Calculate the area of the overspray.

The overspray extends 18 inches (1.5 feet) on either side of the beam, so the total width of the fireproofed area on the decking is:

Total width=2ft (web)+2x1.5ft (overspray)=5ft.

Thus, the area of the overspray on the decking is:

Area of overspray=width×length=5ft×25ft=125sq ft.

Step 4: Calculate the total square footage.

Now, sum the areas of the flanges, the web, and the overspray:

Total area=Area of flanges+Area of web+Area of overspray = 50sq ft+50sq ft+125sq ft=225sq ft.

24. What is NARS?

A. An EPA system for hazard assessment

B. An EPA system for tracking contractor violations and compliance

C. An EPA sampling protocol

D. None of the above

B. An EPA system for tracking contractor violations and compliance

Explanation:

NARS stands for the National Asbestos Registry System, which is used by the EPA to track contractor violations, compliance, and activities related to asbestos management. It helps ensure that contractors meet required regulations and monitor their performance in handling asbestos-related tasks.

A. An EPA system for hazard assessment: This is not the purpose of NARS.

B. An EPA system for tracking contractor violations and compliance: This is the correct definition of NARS.

C. An EPA sampling protocol: NARS is not a sampling protocol; it's a tracking system.

D. None of the above: This is incorrect since option B is the correct answer.

When is personal air sampling not required on asbestos abatement jobs?

A. When the permissible exposure limit is not exceeded

B. When the work is small-scale short duration

C. When a glove-bag is used

D. When air-supplied respirators are used

B. When the work is small-scale short duration

Explanation:

According to OSHA regulations, personal air sampling is not required for asbestos abatement jobs that meet the definition of small-scale, short-duration work. This refers to tasks that are limited in scope and duration and that do not pose a significant risk for exposure to airborne asbestos fibers. In these situations, a full air sampling program may not be necessary, although proper protective measures and controls must still be in place.

A. When the permissible exposure limit is not exceeded: Air sampling is generally required when there's a risk of exposure, regardless of whether the permissible exposure limit (PEL) is exceeded, in order to monitor and assess the environment.

B. When the work is small-scale short duration: This is correct. For certain small-scale short-duration abatement tasks, air sampling may not be required, although other protective measures must be followed.

C. When a glove-bag is used: Glove-bag use typically requires air sampling because it's a containment method used for small, localized abatement, but it does not automatically exempt air sampling requirements.

D. When air-supplied respirators are used: Even when air-supplied respirators are used, personal air sampling may still be required to ensure that workers are not exposed to unsafe levels of asbestos.

A ladder is being need to access the roof of a building 30 feet above the ground. How high must the ladder be?

A. 34'

B. 35'

C. 36'

D. 38'

A. 34'

To determine the correct ladder height, we use the 4-to-1 rule, which states that for every 4 feet of vertical height, the base of the ladder should be 1 foot away from the wall.

The building height is 30 feet.

The ladder forms a right triangle with:

Vertical height = 30 feet

Base distance from the wall = (30 ÷ 4) = 7.5 feet

Using the Pythagorean theorem:

Ladder length^2= (Vertical height)^2+(Base distance)^2

L^2 = (30)^2 + (7.5)^2

L^2 = 900 + 56.25

L^2=956.25

L = square root (956.25)

L = 30.9

Since ladders are sold in standard lengths, you would need a ladder at least 34 feet long to ensure proper placement.

When isolating a room which will have fireproofing abatement performed, it is

recommended to put down the floor plastic first. Why?

A) Any debris generated while hanging wall polyethylene will be caught by the floor

B) It is easier to tape the floor poly to the bare wall than to a wall covered in poly

C) Tearing down the plastic before clearance is made easier by doing this

D) Less likely for water to leak through the floor poly if it is installed first

A) Any debris generated while hanging wall polyethylene will be caught by the floor

Explanation:

When isolating a room for fireproofing abatement, the floor plastic (polyethylene sheeting) is typically installed first because:

Debris containment: Any dust, fibers, or small particles that fall while installing the wall polyethylene will be caught by the floor plastic, preventing contamination and making cleanup easier.

Safety and compliance: This practice helps maintain a controlled environment and minimizes the spread of asbestos or fireproofing materials.

Polychlorinated biphenyls (PCB's) are often encountered on asbestos abatement jobs as a component of which of the following?

A. Sprayed on fire-proofing

B. Spray glues and encapsulants

C. Respirator filters

D. Lighting ballasts

D. Lighting ballasts

Explanation:

Polychlorinated biphenyls (PCBs) were commonly used in lighting ballasts as an insulating and cooling agent in the capacitors of fluorescent light fixtures before being banned in 1979.

During asbestos abatement, especially in older buildings, workers may encounter PCBs in lighting ballasts, requiring proper handling and disposal due to their toxic and persistent environmental impact.

Two bags of asbestos waste somehow fall off a truck on the way to the landfill. By the time the CHP arrives at the site, little kids have started making snowmen out of the asbestos. The judge finds the building owner liable under what doctrine?

A. Strict liability

B. Joint and several liability

C. Negligence

D. Errors and omissions

A. Strict liability

Explanation:

Under environmental law, asbestos is classified as a hazardous material, and its improper handling or disposal can lead to strict liability under laws like the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

Strict liability means that the building owner is held responsible regardless of intent or negligence. Since asbestos is inherently dangerous, anyone responsible for its disposal can be held liable if harm occurs.

Why Not the Other Options?

B) Joint and several liability - This applies when multiple parties share responsibility, but here, the building owner is the primary responsible party.

C) Negligence - Negligence requires proof that the building owner failed a duty of care, but strict liability applies even without proving negligence.

D) Errors and omissions - This usually applies to professional liability (e.g., architects, engineers) rather than environmental hazards.

Which of the following is an engineering control?

A. Negative pressure units

B. Airlocks on a containment

C. Fire extinguishers

D. All of the above

D. All of the above

Explanation:

Engineering controls are physical measures designed to minimize hazards and protect workers by containing or reducing exposure to harmful substances.

A) Negative pressure units - These are essential in asbestos abatement projects, as they create negative air pressure to prevent contaminants from escaping the work area.

B) Airlocks on a containment - Used to control airflow and prevent asbestos fibers or other hazardous materials from escaping the containment area.

C) Fire extinguishers - While commonly associated with fire safety, fire extinguishers are considered an engineering control because they help reduce physical hazards in the workplace.

The AHERA regulation requires which of the following?

A. Friable asbestos must be sampled, and all suspect non-friable asbestos must be assumed

B. All suspect materials must be inspected. At the LEA' s option, the materials can be assumed asbestos containing.

C. Non-friable suspect asbestos may not be sampled under AHERA, as it may become

friable in the process.

D. Friable materials must be sampled, non-friable materials may be either assumed or sampled.

B. All suspect materials must be inspected. At the LEA' s option, the materials can be assumed asbestos containing.

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act, 40 CFR Part 763), Local Education Agencies (LEAs) are required to:

Inspect all suspect asbestos-containing materials (ACMs) in school buildings.

Sample the materials or assume they contain asbestos if they choose not to sample.

This ensures that all potential ACMs are properly managed to protect students and staff from asbestos exposure.

You have just monitored the abatement of 200 square feet VAT in a 3rd grade classroom.

What kind of clearance will you need perform?

A. Visual

B. 3 TEM samples inside, 3 outside

C. 5 TEM samples inside, 5 outside

D. 5 PCM samples inside, 5 outside

D. 5 PCM samples inside, 5 outside

You have just monitored the abatement of 20 square feet of VAT in a 4'x 5' janitor's closet.

What kind of clearance will you now perform?

A. Visual

B. 3 PCM inside, 3 outside

C. 5 TEM inside, 5 outside

D. 5 PCM inside, 0 outside

D. 5 PCM inside, 0 outside

Explanation:

According to AHERA (40 CFR Part 763), clearance air sampling is typically not required for the abatement of non-friable asbestos-containing materials (ACM), such as Vinyl Asbestos Tile (VAT), unless it has been made friable during removal (e.g., by grinding, sanding, or improper removal techniques).

For small-scale projects (less than 160 square feet of friable ACM):

A visual inspection is required to ensure that all asbestos-containing debris is properly cleaned before reoccupying the area.

Air clearance (PCM or TEM) is generally not required unless the VAT was made friable.

On an abatement job, there are a number of hazards present besides asbestos. Whose responsibility is it to recognize these hazards, to sample for them if appropriate, and to control them?

A. Building owner

B. Consultant

C. Competent Person

D. OSHA inspector

C. Competent Person

Explanation:

Under OSHA regulations (29 CFR 1926.1101 and 8 CCR §1529 in California), a Competent Person is required on asbestos abatement jobs to:

Identify and assess all hazards (not just asbestos, but also lead, PCBs, confined spaces, electrical hazards, etc.).

Ensure proper sampling and monitoring of hazards if necessary.

Implement appropriate control measures to protect workers and ensure compliance with safety regulations.

Why Not the Other Options?

A) Building Owner - The building owner has overall responsibility but does not actively inspect or control hazards on-site.

B) Consultant - A consultant may advise on hazards but is not legally responsible for recognizing and controlling them.

D) OSHA Inspector - OSHA inspectors enforce regulations and issue citations but are not responsible for on-site hazard management.

Thus, the Competent Person is the one directly responsible for recognizing, sampling, and controlling all job site hazards.

What is the maximum allowable level of carbon monoxide in Grade D air?

A. 0.5 ppm

B. 5 ppm

C. 10 ppm

D. 15ppm

C. 10 ppm

Explanation:

Carbon monoxide (CO) content of 10 ppm or less;

The TEM results for an AHERA clearance have just come back from the lab. The results are an average of 2000 structures per square millimeter of filter area. The contractor thinks that demolition of sheetrock walls is causing the problem, and has requested the outside samples be analyzed and Z-test performed. How should you respond?

A. Fine, as long as you pay for it

B. The Z-test could be conducted, however the clearance will probably fail

C. The Z-test is not appropriate for the TEM clearances, only PCM

D. It is unlikely that the outside samples would have this high a level of fibers, there for analysis is not prudent

C. The Z-test is not appropriate for the TEM clearances, only PCM

Explanation:

The Z-test is typically used with PCM (Phase Contrast Microscopy) results to statistically compare the number of fibers in the work area with those in the outside air to determine if the clearance passes. However, the Transmission Electron Microscopy (TEM) results used in AHERA clearance testing do not rely on the Z-test because TEM is much more sensitive and detects individual asbestos structures at a much lower threshold.

Z-test is designed for PCM, which counts visible fibers in air samples, not for TEM, which identifies and counts asbestos structures at a much higher resolution.

The clearance results are typically based on a direct comparison of the levels of asbestos structures in the work area to the outside samples, but the Z-test is not applicable to TEM.

Since the Z-test is not used for TEM clearance, the contractor's request for this test is not appropriate.

Which of the following is used to sample for personal exposure to organic vapor when applying spray glue?

A. Soap bubble burette

B. Evacuated canister

C. Charcoal tube

D. Fibrous Aerosol Monitor

C. Charcoal tube

Explanation:

When sampling for personal exposure to organic vapors, such as those that may be released during the application of spray glue, charcoal tubes are commonly used. These tubes are designed to adsorb organic vapors from the air as a worker breathes in, and the trapped vapors can later be analyzed in a laboratory. Charcoal is effective in capturing a broad range of organic compounds, making it ideal for this type of sampling.

Why Not the Other Options?

A) Soap bubble burette - Typically used for measuring gas volume or concentration in a controlled setting, not for organic vapor sampling.

B) Evacuated canister - Used for sampling airborne volatile organic compounds (VOCs) but is not the standard for personal exposure sampling.

D) Fibrous Aerosol Monitor - Used to monitor fibers (like asbestos), not organic vapors.

GFCI must be installed on all:

A. Negative pressure units

B. Power tools

C. Shower wastewater pumps

D. All of the above

D. All of the above

Explanation:

A Ground Fault Circuit Interrupter (GFCI) is a safety device that helps prevent electric shock by detecting any ground fault or leakage current. GFCIs are required by OSHA and NEC (National Electrical Code) in a variety of situations where electrical equipment or tools are used in potentially hazardous environments, particularly in wet or damp locations.

A) Negative pressure units - These units are often used in abatement projects and may involve electrical systems exposed to wet environments, requiring GFCI protection.

B) Power tools - All power tools used in wet or damp locations must be protected by GFCIs to reduce the risk of electric shock.

C) Shower wastewater pumps - These pumps are often in wet or damp locations and therefore require GFCI protection to prevent electrical hazards.

Since GFCI protection is required in all of these scenarios, the correct answer is D) All of the above.

There are 8 sections on the CSST exam. Which of the following lists is correct?

A. Abatement oversight, respirators, PPE, regulations, liability and insurance, air monitoring, inspections, health effects, general information

B. Abatement oversight, respirators and PPE, regulations, liability and insurance, air monitoring, inspections, record and reports, surveys.

C. Project management, respirators and PPE, regulations, liability and insurance, air monitoring, inspections, records and reports, general information

D. Abatement oversight, respirators, PPE, regulations, liability and insurance, air monitoring, inspections, health effects, surveys.

B. Abatement oversight, respirators and PPE, regulations, liability and insurance, air monitoring, inspections, record and reports, surveys.

Explanation:

The CSST (Certified Site Surveillance Technician) exam covers several critical areas relevant to asbestos abatement. The correct list of sections includes:

Abatement oversight

Respirators and PPE (Personal Protective Equipment)

Regulations

Liability and insurance

Air monitoring

Inspections

Record and reports

Surveys

This set of topics aligns with the core responsibilities of a site surveillance technician in asbestos projects, ensuring they understand safety, regulations, and documentation.

Under what circumstances is it recommended that workers HEPA-vacuum their coveralls before exiting the work area?

A. When a remote shower is being used

B. When they are working with non-friable materials

C. For small scale, short duration work.

D. When they have been performing glove-bag activities

D. When they have been performing glove-bag activities

Explanation:

Workers are advised to HEPA-vacuum their coveralls before exiting the work area, especially after performing glove-bag activities. A glove-bag is used in asbestos abatement to enclose and remove asbestos-containing materials (ACMs) in a controlled manner. Due to the nature of the task, there is a higher likelihood of asbestos contamination on the worker's protective clothing.

By HEPA-vacuuming the coveralls, workers can remove any asbestos fibers or dust that might have settled on them during the process, reducing the risk of contamination during decontamination and exiting the work area.

Why Not the Other Options?

A) When a remote shower is being used - While workers may need to shower before leaving the work area, the HEPA-vacuuming specifically addresses the removal of asbestos from clothing and gear, which is critical in glove-bag activities.

B) When they are working with non-friable materials - Non-friable materials are less likely to release asbestos fibers, reducing the need for HEPA-vacuuming coveralls, although it's still a good practice to follow standard safety procedures.

C) For small scale, short duration work - Small scale, short-duration work may not involve the same level of asbestos exposure, so HEPA-vacuuming may not always be necessary in these situations unless specified by project guidelines.

According to Cal/OSHA, a double polyethylene floor layer is recommended for containments. Cal/OSHA recommends that the top floor layer extend approximately how far up the walls over the polyethylene on the walls?

A. 6"

B. 12"

C. 21"

D. 24"

B. 12"

Explanation:

According to Cal/OSHA (California Occupational Safety and Health Administration) guidelines, when constructing a containment for asbestos abatement, a double polyethylene floor layer is recommended. The top layer of polyethylene on the floor should extend approximately 12 inches up the walls over the polyethylene on the walls. This helps ensure that any debris or asbestos fibers on the floor are contained and prevent contamination beyond the work area.

This 12-inch overlap is critical to maintaining a properly sealed containment area.

Who is responsible under AHERA for keeping a copy of the operations and management plan?

A. The EPA Regional office

B. The inspector who performed the work, or the company that the inspector works for

C. The LEA

D. The school maintenance staff

C. The LEA

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), the responsibility for keeping a copy of the Operations and Maintenance (O&M) Plan lies with the Local Education Agency (LEA).

The LEA is required to maintain this plan and ensure that it is available for review. The plan outlines how the school will manage asbestos-containing materials (ACMs) in the building to minimize exposure and risk. It includes strategies for routine maintenance, inspections, and response to asbestos issues.

Why Not the Other Options?

A) The EPA Regional office - While the EPA enforces AHERA regulations, they do not retain copies of the O&M plans; that responsibility lies with the LEA.

B) The inspector who performed the work, or the company that the inspector works for - The inspector may assist in creating or reviewing the O&M plan, but the responsibility for keeping it falls to the LEA.

D) The school maintenance staff - The maintenance staff may be involved in the implementation of the O&M plan, but they are not responsible for keeping a copy of the plan.

EPA defined Category-2 non-friable materials include:

A. Transite

B. Gaskets

C. Floor tile

D. Roof felts

A. Transite

Explanation:

Under EPA regulations, Category-2 non-friable asbestos-containing materials (ACMs) are those materials that are not easily crumbled or reduced to powder and are typically considered less hazardous than friable asbestos materials.

Category-2 non-friable materials include materials that, under normal conditions, do not release asbestos fibers unless they are significantly disturbed, such as through mechanical damage or intense weathering. Transite (a type of cement asbestos board) is one of the most common materials classified as Category-2 non-friable ACM.

Why Not the Other Options?

B) Gaskets - Gaskets are typically Category-1 non-friable materials (materials that can be easily damaged or crushed).

C) Floor tile - Floor tiles made with asbestos are often Category-1 or Category-2, depending on their condition, but they are generally not listed specifically as Category-2 in most cases.

D) Roof felts - Roof felts can also be non-friable, but they are often classified under Category-1 non-friable materials, depending on the product.

Trowelled-on Boiler insulation with 20% of its surface delaminated in a localized area, but with little or no potential for further damaged, falls into which AHERA category.

A. Damaged Surfacing Material

B. Significantly damaged Thermal Systems Insulation

C. Potential for damage

D. Damaged Thermal Systems Insulation

D. Damaged Thermal Systems Insulation

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), thermal system insulation (TSI) refers to materials that are used to insulate pipes, boilers, and other thermal systems.

When thermal system insulation, such as troweled-on boiler insulation, is delaminated in a localized area but with little or no potential for further damage, it is classified as "Damaged Thermal Systems Insulation". This classification applies because the material is no longer in good condition but does not yet meet the criteria for significant damage or the potential for more widespread damage.

Why Not the Other Options?

A) Damaged Surfacing Material - This applies to materials that are sprayed on or applied to surfaces like ceilings and walls and would not apply to troweled-on boiler insulation.

B) Significantly damaged Thermal Systems Insulation - This category applies when the insulation has extensive damage, typically when more than 25% of the material is damaged. In this case, only a localized area is delaminated.

C) Potential for damage - This category applies to materials that are intact but at risk of damage. Since the insulation is already delaminated, it doesn't fit this category.

A room is 20' long, 30' wide and 10' high. How many negative pressure units are required to achieve 4 air changes per hour?

A. 1

B. 2

C. 3

D. 4

A. 1

Step 1: Calculate the room volume

The room's volume is:

Volume =Length × Width × Height

Volume=20×30 ×10 =6,000 cubic feet

Step 2: Determine the airflow required for 4 ACH:

Air changes per hour (ACH) is calculated by:

Airflow required (CFM)= (Room Volume × ACH​) / 60

Airflow required (CFM)= (6000x4) / 60 = 400 CFM

Step 3: Determine number of negative pressure units needed

= 6000/400 = 15

= 15/15 PLM = 1​

Under AHERA, all LEA's must have an inspection completed by which date?

A. July 1989

B. October 1988

C. July 1988

D. October 1989

B. October 1988

Explanation:

AHERA mandated that Local Education Agencies (LEAs) complete their initial asbestos inspections by October 12, 1988.

Grade D air which is supplied from a compressed air source requires which of the following?

A. A carbon monoxide alarm on the compressor

B. And oilless compressor

C. Zero water vapor in the compressed air

D. None of the above.

A. A carbon monoxide alarm on the compressor

Explanation:

According to OSHA and ANSI Z88.2 standards for Grade D breathing air, when air is supplied from a compressed air source, the air must be monitored for contaminants, including carbon monoxide. Specifically, carbon monoxide (CO) poses a serious risk to workers, so a carbon monoxide alarm is required on the compressor to ensure that the levels of CO do not exceed 10 ppm in the compressed air, which is the permissible limit for Grade D air.

Which of the following is the most serious condition?

A. Heat stress

B. Heat stroke

C. Heat cramps

D. Asbestos warts

B. Heat stroke

Explanation:

Heat stroke is the most serious condition among the options listed. It is a medical emergency that occurs when the body's temperature regulation system fails, causing the body temperature to rise to dangerous levels (above 104°F or 40°C). This can lead to organ failure, brain damage, and even death if not treated immediately. Symptoms include confusion, rapid pulse, loss of consciousness, and hot, dry skin.

Why Not the Other Options?

A) Heat stress - Heat stress is a milder condition compared to heat stroke. It occurs when the body is unable to cool itself effectively in hot environments, leading to symptoms like heavy sweating, dizziness, or nausea, but it is not life-threatening if managed properly.

C) Heat cramps - Heat cramps are painful muscle contractions that occur after prolonged exposure to high heat. While uncomfortable, they are less serious than heat stroke and can typically be treated by hydrating and cooling the body.

D) Asbestos warts - Asbestos warts are benign growths on the skin caused by the physical irritation of asbestos fibers. While asbestos exposure is harmful, asbestos warts are not life-threatening compared to the immediate danger posed by heat stroke.

A metal-with poor cohesion is a good candidate for

A. Bridging encapsulant

B. Penetrating encapsulant

B. Penetrating encapsulant

Explanation:

A metal with poor cohesion is more likely to benefit from a penetrating encapsulant. Penetrating encapsulants are designed to soak into porous or loose materials, improving the adhesion and strength of the surface. These encapsulants bind fibers or particles more effectively by penetrating the surface, making them ideal for materials with poor cohesion, such as certain metals or deteriorating surfaces.

Why Not the Other Option?

A) Bridging encapsulant - A bridging encapsulant is typically used for surfaces that need to form a protective barrier over them (such as those with good cohesion or more solid surfaces). It creates a physical barrier, which might not be as effective for metals with poor cohesion where penetration is needed to bond the surface.

After conducting air monitoring in a building for general hazard evaluation purposes, a building owner must inform the tenants of the results within 15 days as require by:

A. Cal/Osha regulation 8 CCF 1528

B. 40 CFR 763

C. Not Required but is a good idea to reduce liability

D. Connelly Bill, eg: Asbestos Notification Act

D. Connelly Bill, eg: Asbestos Notification Act

Explanation:

Under the Connelly Bill (also known as the Asbestos Notification Act), which was enacted in California, the building owner is required to inform tenants of the results of air monitoring within 15 days after it has been conducted for general hazard evaluation purposes. This law helps ensure that tenants are aware of the potential risks of asbestos exposure and can take necessary precautions.

Why Not the Other Options?

A) Cal/Osha regulation 8 CCR 1528 - While this regulation governs asbestos exposure and monitoring in California, it does not specifically mandate that building owners inform tenants within 15 days of air monitoring results.

B) 40 CFR 763 - This regulation under the EPA is related to asbestos management plans in schools and public buildings but does not specifically address the 15-day requirement for notifying tenants after air monitoring.

C) Not Required but is a good idea to reduce liability - This is incorrect; it is required under the Connelly Bill. While informing tenants may help reduce liability, it is a legal requirement under the law.

The AHERA regulation, 40 CFR 763, is a portion of which of the following?

A. The Resource Conservation and Recovery Act (RCRA)

B. The Toxic Substance Control Act (TSCA)

C. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)

D. None of the above

B. The Toxic Substance Control Act (TSCA)

Explanation:

The AHERA (Asbestos Hazard Emergency Response Act) regulation, which is part of 40 CFR 763, is a portion of the Toxic Substances Control Act (TSCA). TSCA is a federal law that gives the Environmental Protection Agency (EPA) the authority to regulate the use of chemicals and hazardous substances, including asbestos. AHERA specifically addresses asbestos in schools and requires schools to inspect for asbestos, develop management plans, and take action to reduce asbestos risks.

Why Not the Other Options?

A) The Resource Conservation and Recovery Act (RCRA) - This act focuses on the regulation of hazardous waste and does not cover asbestos specifically.

C) The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) - FIFRA deals with the regulation of pesticides, not asbestos.

D) None of the above - This is incorrect because AHERA is indeed a part of the TSCA.

A trench is being evacuated in order to access and abate a transite water main. The trench is 6' deep. Which of the following should be done?

A. The trench should be shored

B. No employees should enter the trench under any circumstances

C. The trench should be treated as a confined space, with required air testing performed

D. A backhoe should be on standby to dig out the trench in case it collapses on employees.

A. The trench should be shored

Explanation:

According to OSHA regulations (specifically 1926 Subpart P: Excavations), any trench 6 feet deep or more requires shoring, shielding, or sloping to prevent a cave-in and protect workers from potential hazards. Trench shoring involves the use of supports to prevent the trench walls from collapsing, ensuring the safety of workers entering the trench.

Why Not the Other Options?

B) No employees should enter the trench under any circumstances - This is not correct. While there are hazards, the trench can be safely worked in as long as proper safety measures like shoring or trench boxes are in place.

C) The trench should be treated as a confined space, with required air testing performed - This is not necessarily correct unless the trench meets the definition of a confined space (which usually means limited means of entry and exit and potential for hazardous atmosphere). For a 6-foot trench, the primary concern is the risk of cave-ins.

D) A backhoe should be on standby to dig out the trench in case it collapses on employees - While having equipment on standby may be a good safety practice, it does not replace the requirement to shore the trench properly. Simply having a backhoe on standby is insufficient for preventing a collapse.

The OSHA protection factor for a PAPR for asbestos work is

A. 10

B. 25

C. 50

D. 100

C. 50

Explanation:

The OSHA protection factor for a Powered Air-Purifying Respirator (PAPR) used for asbestos work is 50. This means that the PAPR provides a protection level 50 times greater than the concentration of asbestos fibers in the air. A PAPR is typically used when working with asbestos because it provides a high level of protection, especially for workers in environments with high asbestos concentrations.

Powered Air-Purifying Respirator (PAPR):

PAPR has a half mask facepiece the APF would be 50.

Full-facepiece: 1,000

PAPR has a loose fitting hood the APF is 25

The risk of which asbestos diseases are increased by smoking?

A. Asbestosis and mesothelioma

B. Asbestosis and lung cancer

C. Lung cancer and mesothelioma

D. Lung cancer, asbestosis, and mesothelioma

B) Asbestosis and lung cancer

Explanation:

Smoking significantly increases the risk of lung cancer in individuals exposed to asbestos. While both smoking and asbestos exposure are independent risk factors for lung cancer, their combination creates a synergistic effect, making the risk much higher than either factor alone.

Smoking also exacerbates asbestosis, a chronic lung disease caused by inhaling asbestos fibers, because smoking damages the lungs and impairs their ability to clear asbestos fibers.

Why Not the Other Options?

A) Asbestosis and mesothelioma - Smoking does not increase the risk of mesothelioma, as mesothelioma is primarily caused by asbestos exposure alone.

C) Lung cancer and mesothelioma - Smoking increases the risk of lung cancer, but not mesothelioma.

D) Lung cancer, asbestosis, and mesothelioma - This is incorrect because smoking does not affect the risk of mesothelioma.

Installation for a laid-in ceiling tile system over an acoustical spray asbestos ceiling is an example of which of the following AHERA Response Actions

A. Encapsulation

B. Removal

C. Enclosure

D. Restricting access

C. Enclosure

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), enclosure is a response action where a physical barrier is installed to separate asbestos-containing materials (ACM) from the environment, preventing fiber release.

Installing a laid-in ceiling tile system over an acoustical spray asbestos ceiling effectively creates a barrier that contains the asbestos, which aligns with the definition of enclosure rather than encapsulation or removal.

Why Not the Other Options?

A) Encapsulation - This involves applying a sealant or binding agent to asbestos material to prevent fiber release. Since a new ceiling tile system is being installed rather than a coating being applied to the asbestos material, this is not encapsulation.

B) Removal - Removal would involve physically taking out the asbestos-containing ceiling material, which is not happening in this case.

D) Restricting access - This refers to limiting entry to the area (e.g., closing off rooms or buildings), which is different from enclosing the asbestos material with a permanent barrier.

Which of the following temperatures are safe to use a standard glove-bag at?

A. 120 F

B. 140 F

C. 160 F

D. 180 F

A. 120 F

Explanation:

Standard glove-bags used for asbestos abatement are typically designed to withstand temperatures up to 120°F. Exceeding this temperature can cause the plastic material of the glove-bag to weaken, melt, or fail, increasing the risk of asbestos fiber release.

Why Not the Other Options?

B) 140°F, C) 160°F, and D) 180°F - These temperatures are too high for standard glove-bags, as the plastic may soften, deform, or rupture, leading to containment failure.

For higher-temperature applications, such as working with hot pipes or boilers, high-temperature-resistant glove-bags made of heat-resistant materials should be used instead of standard glove-bags.

If you quantitatively fit test a half-face respirator, and find that it has a 100 protection factor, what level of asbestos fibers may the worker be exposed to without exceeding the OSHA permissible exposure limit?

A. 10.0 f/cc

B. 2.5 f/cc

C. 5.0 f/cc

D. 1.0 f/cc

A. 10.0 f/cc

Explanation:

OSHA's Assigned Protection Factor (APF) for a half-face respirator is 10, meaning it should only be used in environments where the exposure level is no more than 10 times the OSHA Permissible Exposure Limit (PEL).

Step-by-step calculation:

The OSHA PEL for asbestos is 0.1 f/cc (fibers per cubic centimeter).

If a respirator has a protection factor of 100, it theoretically allows exposure 100 times the PEL before exceeding the limit.

0.1 f/cc × 100 = 10.0 f/cc (This would apply if using a full-face respirator with an APF of 100).

Since the question states a half-face respirator, we apply the OSHA-recognized APF of 10, meaning:

0.1 f/cc x 10 = 1.0 f/cc

This means the worker should not be exposed to more than 1.0 f/cc, making D (1.0 f/cc) the correct answer.

However, if OSHA were to allow the fit test-derived protection factor of 100, then 10.0 f/cc would be the correct answer. But this is not OSHA's official approach.

What is the recommended volume range for an AHERA clearance with a 25-mm cassette?

A. 1000-2000 liters

B. 1200-2400 liters

C. 1020 - 1800 liters

D. 1200-1800 liters

D. 1200-1800 liters

Explanation:

For AHERA clearance sampling, the recommended air volume range for a 25-mm cassette with a 0.45-µm filter is typically 1,200 to 1,800 liters of air. This ensures an adequate fiber collection for Transmission Electron Microscopy (TEM) analysis while preventing overloading of the filter.

Why Not the Other Options?

A) 1000-2000 liters - The lower limit (1000 L) is slightly below the recommended minimum volume.

B) 1200-2400 liters - The upper limit (2400 L) may risk filter overloading, making it too high for optimal sampling.

C) 1020-1800 liters - While this range includes the correct upper limit (1800 L), the lower limit (1020 L) is not a standard recommendation under AHERA.

Which of the following is an administrative control?

A. Negative pressure units

B. Ice vests

C. Supplied air respirators

D. Rest breaks

D. Rest breaks

Explanation:

Administrative controls are work practices and policies designed to reduce exposure to hazards without directly altering the physical environment. These include scheduling changes, training, and work-rest cycles.

Rest breaks help minimize heat stress and fatigue, reducing the likelihood of mistakes and increasing worker safety.

OSHA and other safety organizations recommend scheduled rest periods in hazardous work environments, especially for tasks involving asbestos abatement or high heat conditions.

Why Not the Other Options?

A) Negative pressure units - These are engineering controls because they physically modify the work environment by removing contaminated air.

B) Ice vests - These are a form of Personal Protective Equipment (PPE), not an administrative control.

C) Supplied air respirators - These are PPE, as they provide workers with clean air but do not change work practices.

When an EPA inspector makes an inspection of an LEA's compliance with AHERA, which

of the following must be done?

A. Provide written notice of findings before leaving the school property

B. Present credentials to the school principal.

C. Give 5 days notice to the LEA

D. All of the above

B. Present credentials to the school principal.

Explanation:

When an EPA inspector conducts an AHERA (Asbestos Hazard Emergency Response Act) compliance inspection at a Local Education Agency (LEA), they are required to:

✅ Present credentials to the school principal or designated official before starting the inspection. This ensures the inspector is properly identified and authorized to conduct the evaluation.

Why Not the Other Options?

A) Provide written notice of findings before leaving the school property - ❌ Incorrect. The inspector is not required to provide written findings immediately. Instead, the EPA typically issues an official report later.

C) Give 5 days' notice to the LEA - ❌ Incorrect. EPA inspections under AHERA are often unannounced to ensure compliance without prior preparation.

When constructing an equipment room and decontamination facility, how far up the wall

should the floor plastic go?

A. 6"

B. 12"

C. 24"

D. None of the above

C. 24"

Explanation:

When constructing an equipment room and decontamination facility for asbestos abatement, the floor plastic should extend at least 24 inches (2 feet) up the walls. This ensures:

✅ A secure seal between the floor plastic and wall plastic, reducing the risk of fiber leakage.

✅ Durability, preventing tears or gaps at the floor-wall junction.

✅ Proper containment, as required by AHERA and OSHA regulations for regulated asbestos work

To qualify for the CSST exam, a person needs to have:

A. College degree in science and 6 months experience

B. A high school diploma and 6 months experience

C. A year's experience unless you have a college degree

D. An AA degree and 6 months experience

C. A year's experience unless you have a college degree

Explanation:

To qualify for the Certified Site Surveillance Technician (CSST) exam in California, a person must meet the following requirements:

✅ One year (12 months) of field experience in asbestos abatement unless they have a college degree in a related field.

✅ If they do have a college degree, then less experience (typically 6 months) is required.

X-rays are part of the medical exam or asbestos workers because:

A. They indicate individuals who should not wear respirators

B. They can indicate preexisting asbestos exposure

C. Scarring and pleural plaques will show up under and x-ray, indicating previous exposure

D. They provide evidence of mesothelioma.

C. Scarring and pleural plaques will show up under and x-ray, indicating previous exposure

Explanation:

Chest X-rays are a standard part of the medical exam for asbestos workers because they can detect lung abnormalities caused by asbestos exposure, such as:

✅ Pleural plaques - Thickening or calcification of the pleura, often linked to past asbestos exposure.

✅ Lung scarring (fibrosis) - A sign of asbestosis, which results from prolonged asbestos exposure.

When does Cal/OSHA not require a negative pressure enclosure:

A. When it is infeasible

B. When it is impractical

C. When it is unsafe

D. All of the above

D. All of the above

Explanation:

Cal/OSHA requires a negative pressure enclosure (NPE) for most asbestos abatement projects to prevent fiber release. However, exceptions exist when an NPE is:

✅ Infeasible - When it is physically impossible to install an enclosure (e.g., on certain outdoor projects).

✅ Impractical - If the enclosure would not effectively contain fibers or hinder the work process.

✅ Unsafe - If creating an enclosure would introduce hazards greater than the asbestos exposure itself (e.g., confined spaces with limited ventilation).

How frequently must the LEA notify parents concerning asbestos activities in the school?

A. At least 10 days prior to each abatement project

B. Quarterly it there are 1iiable materials

C. Annually if there are friable or non-friable materials

D. Within 15 days of the beginning of each school year.

C. Annually if there are friable or non-friable materials

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), Local Education Agencies (LEAs) are required to notify parents, teachers, and employees annually about:

✅ The presence of asbestos-containing materials (ACMs) (both friable and non-friable) in the school.

✅ Any asbestos-related activities such as inspections, response actions, or abatement projects.

Which of the following contains the EPA NESHAPS regulations pertaining to asbestos?

A. 40 CFR 763

B. 8 CCR 1529

C. 40 CFR 61

D. 40 CFR 49

C. 40 CFR 61

Explanation:

The EPA's NESHAP (National Emission Standards for Hazardous Air Pollutants) regulations for asbestos are found in:

✅ 40 CFR Part 61, Subpart M - This section of the Clean Air Act regulates asbestos emissions from demolition, renovation, and disposal activities.

You are monitoring the abatement of all insulation on a mechanical tank which is 16' long and has a 3' diameter in a school. Following the visual inspection, you collect five PCM samples inside the work area, with a sample volume of 3,900 liters each. All of the samples came back less than 0.01 fibers/cc by NIOSH 7400 method, so you cleared the zone. What did you do wrong?

A. Insufficient sample volume

B. Insufficient number of samples for the size of the work area

C. Excess material quantity for this method

D. Nothing wrong.

C. Excess material quantity for this method

Explanation:

Under AHERA (40 CFR 763), when performing asbestos abatement clearance in a school, a mechanical tank insulation removal falls under the thermal system insulation (TSI) category.

What Went Wrong?

✅ PCM (Phase Contrast Microscopy) is not appropriate for TSI abatement clearance.

✅ TSI requires Transmission Electron Microscopy (TEM), not PCM, because PCM cannot differentiate asbestos fibers from non-asbestos fibers.

✅ AHERA clearance for TSI requires 5 TEM samples inside and 5 outside, not PCM.

You walk into a mechanical room and see a large insulated tank. The vessel has two pipes going into one end, a pipe on the top and a pipe on the bottom. What function does the tank

probably perform?

A. Hot water boiler

B. Heat exchanger

C. Chiller

D. Expansion tank

B. Heat exchanger

Explanation:

A heat exchanger is designed to transfer heat between two fluids (liquid or gas) without them mixing. Based on the description:

✅ Two pipes entering one end - Suggests a flow of fluid in and out.

✅ One pipe on the top and one on the bottom - Indicates heat transfer between two separate fluids.

What disposal requirements pertain to friable materials with 0.1% to <1.0% asbestos content?

A. Dispose in asbestos landfill with all appropriate labeling, 6" cover, etc.

B. Dispose in Class 1 landfill with all appropriate labeling

C. Dispose in municipal landfill with asbestos warning label while bags are being handled

D. No disposal requirements

C. Dispose in municipal landfill with asbestos warning label while bags are being handled

Explanation:

Under EPA NESHAP (40 CFR 61, Subpart M) and Cal/OSHA (8 CCR 1529) regulations:

✅ Friable materials containing 0.1% to <1.0% asbestos are not regulated as asbestos-containing materials (ACM) under NESHAP.

✅ However, OSHA still considers them hazardous, requiring proper handling.

✅ They can be disposed of in a municipal landfill but must have asbestos warning labels while being handled to ensure worker safety.

A "fire watch" is required by Cal/OSHA regulations in which of the following conditions?

A. It is a duty fulfilled by the clean room attendant

B. When a high rise fireproofing removal being conducted, someone must be on the floor

full time to watch for potential fires

C. When welding is occurring near flammable materials

D. None of the above

C. When welding is occurring near flammable materials

Explanation:

Under Cal/OSHA regulations (8 CCR 1529 & 8 CCR 4848) and NFPA (National Fire Protection Association) 51B, a fire watch is required when:

✅ Welding, cutting, or other hot work is performed near flammable materials or in areas where fire hazards exist.

✅ A fire watch must remain on-site for at least 30 minutes after hot work ends to monitor for smoldering fires.

✅ Fire extinguishers or other suppression equipment must be readily available.

Why Not the Other Options?

A) It is a duty fulfilled by the clean room attendant - ❌ Incorrect.

A clean room attendant is responsible for contamination control, not fire safety.

B) When high-rise fireproofing removal is being conducted, someone must be on the floor full-time to watch for potential fires - ❌ Incorrect.

While fire risks exist in fireproofing removal, a dedicated fire watch is not explicitly required unless hot work (e.g., torching or grinding) is involved.

D) None of the above - ❌ Incorrect.

Fire watches are required in hot work situations near flammable materials.

A worker is on the clean side of the bag-out chamber, and is receiving labeled bags, putting them into a hopper and wheeling it out to the dumpster. The worker should be wearing:

A. Street clothes are adequate

B. A half-face respirator and coverall

C. A PAPR

D. A coverall, respirator is optional

B. A half-face respirator and coverall

Explanation:

In this scenario, the worker is handling labeled bags of potentially contaminated asbestos materials in the clean side of a bag-out chamber, which is an area where some level of asbestos exposure could still occur.

Cal/OSHA and OSHA requirements specify that workers handling or potentially exposed to asbestos waste must wear appropriate personal protective equipment (PPE):

✅ A half-face respirator is required because there could still be minimal airborne asbestos in the area, and respirators are necessary to protect against even low concentrations of asbestos.

✅ Coveralls are required to prevent the contamination of street clothes and to provide basic protection from asbestos exposure.

Why Not the Other Options?

A) Street clothes are adequate - ❌ Incorrect.

Street clothes are not adequate for handling asbestos-contaminated waste because they don't provide protection against contamination.

C) A PAPR - ❌ Incorrect.

A PAPR (Powered Air Purifying Respirator) is not required for handling asbestos waste in this type of scenario, unless high exposure levels are anticipated, which is unlikely here.

D) A coverall, respirator is optional - ❌ Incorrect.

Respirators are not optional when working in areas where there could be airborne asbestos fibers.

A portable ladder must be tied down or blocked off to prevent slipping under which of the following circumstances?

A. When the ladder extends less than three feet over roof height

B. Under all circumstances

C. When the ladder is being used at a slant of less than 4:1

D. When the ladder is being used at a slant of greater than 4:1

A. When the ladder extends less than three feet over roof height

Explanation:

A portable ladder must be properly secured to prevent slipping in various situations. According to OSHA regulations (29 CFR 1926.1053), a portable ladder must be tied off or blocked when it does not extend sufficiently above the edge it is used to access, which is generally three feet. This ensures that the ladder remains stable and is less likely to slip when the worker is ascending or descending.

Why Not the Other Options?

B) Under all circumstances - ❌ Incorrect.

While securing the ladder is a best practice, it is not required under all circumstances. The requirement specifically applies when the ladder does not extend 3 feet above the landing.

C) When the ladder is being used at a slant of less than 4:1 - ❌ Incorrect.

The 4:1 slant ratio (4 feet horizontal for every 1 foot vertical) affects the stability of the ladder but does not automatically require it to be tied off unless the 3 feet above the landing rule is violated.

D) When the ladder is being used at a slant of greater than 4:1 - ❌ Incorrect.

When the ladder is at a steeper angle (greater than 4:1), it is less stable and may require other safety precautions, but securing the ladder is not specifically required unless it falls below the 3-foot overhang rule.

Which of the following asbestos-containing materials was used in the most buildings in the US?

A. Structural fireproofing

B. Boiler and pipe insulation

C. Piper hanger blocks

D. Loose fill insulation

B. Boiler and pipe insulation

Explanation:

Boiler and pipe insulation made with asbestos was one of the most commonly used asbestos-containing materials (ACMs) in buildings throughout the United States. These materials were primarily used in industrial, commercial, and residential settings for thermal insulation and fireproofing. Asbestos was valued for its heat resistance and insulating properties, especially in high-temperature areas such as boilers, pipes, and steam lines.

Why Not the Other Options?

A) Structural fireproofing - ❌ Incorrect. While asbestos-containing fireproofing materials were commonly used, they were not as prevalent as boiler and pipe insulation in terms of overall usage in the construction of buildings across the U.S.

C) Pipe hanger blocks - ❌ Incorrect. Pipe hanger blocks containing asbestos were used but in a much smaller quantity compared to the large-scale use of boiler and pipe insulation.

D) Loose fill insulation - ❌ Incorrect. Loose fill insulation (often used in attics) was used in some buildings, but it was not as widely used as pipe and boiler insulation. It is also less commonly found today due to its high potential for disturbance and fiber release.

You are conducting an AHERA survey, and are collecting bulk samples of an acoustical ceiling material. The material appears to have been sprayed on. The material occurs only in four adjacent classrooms, each of which is 750 square feet. How many bulk samples should you

collect of the material.

A. 1

B. 3

C. 5

D. 7

C. 5

Explanation:

Under AHERA regulations (40 CFR 763), the number of bulk samples required for asbestos surveys depends on the area and type of material being sampled. For sprayed-on acoustical ceiling materials, the guidance generally requires at least 3 bulk samples for the first 1,000 square feet and additional samples for each additional 1,000 square feet or portion thereof.

Since you are surveying four classrooms, each 750 square feet, the total area of the acoustical ceiling material is 3,000 square feet (750 sq. ft. x 4 classrooms).

For areas less than or equal to 1,000 square feet, you need at least 3 bulk samples. Since the total area is 3,000 square feet (which is a bit over 2,000 square feet), 5 samples would be required for accurate sampling across all areas.

Claims made insurance requires that, in order to be covered by the policy, the claim must be made when?

A. During the policy period

B. Anytime as long as the incident occurred during the policy period

C. Within 30 years of an individual's termination of employment

D. Within 30 years of when the incident occurred.

A. During the policy period

Explanation:

Claims-made insurance requires that the claim must be made during the policy period in order for it to be covered by the policy. This type of insurance only covers claims that are reported while the policy is active, regardless of when the incident occurred, as long as the claim is made during the policy term.

Which of the following is the recommend visual inspection and clearance testing protocol?

A. Conduct visual inspection, remove wall plastic, remove floor plastic, wet wipe walls, wet wipe floors, visually inspect, perform clearance sampling

B. Conduct visual inspection, encapsulate plastic, remove floor plastic, remove wall plastic, wet wipe walls, wet wipe floors, visually inspect, perform clearance sampling

C. Conduct visual inspection, encapsulate plastic, remove floor plastic, remove wall plastic, wet wipe walls, wet wipe floors, perform clearance sampling, visually inspect

D. Conduct visual inspection, encapsulate plastic, remove wall plastic, remove floor plastic, wet wipe walls, wet wipe floors, visually inspection, perform clearance sampling

D. Conduct visual inspection, encapsulate plastic, remove wall plastic, remove floor plastic, wet wipe walls, wet wipe floors, visually inspection, perform clearance sampling

Explanation:

The recommended protocol for visual inspection and clearance testing follows a specific order to ensure proper containment removal and testing. The correct steps are:

1. Visual inspection: The area should be thoroughly inspected to ensure no visible asbestos contamination or residues remain.

2. Encapsulate plastic: Before removing the plastic sheeting, it is generally recommended to encapsulate (seal) the plastic to avoid any disturbance and potential contamination.

3. Remove wall plastic: Carefully remove the wall plastic after ensuring the area is sealed and cleaned.

4. Remove floor plastic: Similarly, remove the floor plastic after sealing the area.

5. Wet wipe walls and floors: Clean any remaining surfaces with wet wipes to remove any potential asbestos residues.

6. Visual inspection (again): Reinspect the area to ensure it is clean and free from asbestos contamination.

7. Perform clearance sampling: Finally, perform clearance sampling to verify the effectiveness of the cleaning process and confirm that the area meets the required clearance levels.

Scanning electron microscopy (SEM) may be used for which of the following under AHERA?

A. Bulk sample analysis

B. Clearance air sample analysis

C. Bulk sample verification following PLM analysis

D. None of the above

C) Bulk sample verification following PLM analysis

Explanation:

Scanning Electron Microscopy (SEM) is often used as a complementary method to confirm the presence of asbestos in bulk samples, especially following the analysis of bulk samples using Polarized Light Microscopy (PLM). SEM provides high magnification and can be used to further verify or differentiate fibers, particularly when there is a need for greater accuracy or in ambiguous cases.

Ground fault circuit interrupters (GFCI) are used for:

A. Running several cords off of one power outlet

B. Converting 3-prong plug to a 2-prong plug

C. Shutting down a circuit if there is a sharp drop in the line power

D. Converting 220 power to 110 power

C. Shutting down a circuit if there is a sharp drop in the line power

Explanation:

Ground Fault Circuit Interrupters (GFCIs) are designed to shut down a circuit if there is a ground fault or a difference in the current between the hot and neutral wires, which can happen if there is a sharp drop in power or when an electrical path deviates, posing a shock risk. GFCIs protect individuals from electrical shock hazards, particularly in areas where electrical equipment may come into contact with water, such as bathrooms, kitchens, or construction sites.

Qualitative fit testing is acceptable by Cal/OSHA up to a protection factor of?

A. 10

B. 25

C. 50

D. 100

A) 10

Explanation:

Cal/OSHA allows qualitative fit testing (QLFT) for respirators with a protection factor up to 10. This type of fit testing uses sensory responses (like taste or smell) to determine if the respirator provides an adequate seal. It is considered suitable for lower protection factors (up to 10) but is not acceptable for respirators requiring higher protection factors.

You are monitoring the abatement of all insulation on a mechanical tank which is 10' long and have a 3' diameter in a school. Following the visual inspection, you collect five PCM samples inside the work are, with a sample volume of 3,800 liters each. All of the samples came back less than 0.01 fibers/cc by NIOSH 7400 method, so you cleared the zone. What did you do wrong?

A. Insufficient sample volume

B. Insufficient number of samples for the size of the work area

C. Excess material quantity for this method

D. Nothing wrong

B. Insufficient number of samples for the size of the work area

Explanation:

Under AHERA regulations, for an abatement area of greater than 1,000 square feet, you are required to collect a minimum of 5 air samples inside the containment (which you did), but you may need additional sampling based on the complexity of the area or the volume of the material being removed. Since the mechanical tank in question is 10' long and 3' in diameter, it might exceed 1,000 cubic feet of abated material, which generally requires more samples to be considered adequate for clearance.

For larger or more complex work areas, additional samples might be required to ensure that there are no fibers present in the air after the abatement.

The sample volume of 3,800 liters per sample is adequate, and the NIOSH 7400 method is appropriate for analyzing the air samples. However, you may have needed more than five samples to ensure the clearance level was sufficiently met.

Which of the following are not included in an AHERA survey?

A. Roofing felts on a low walkway cover (portico) between classes

B. Transite panels on a roof-mounted exhaust duct from a woodshop

C. Friable stucco on the columns supporting a covered walkway between classes

D. Pipe lagging debris in a crawlspace which is never entered by students

D) Pipe lagging debris in a crawlspace which is never entered by students

Explanation:

Under the AHERA regulations, an asbestos survey is required to identify asbestos-containing materials (ACMs) in school buildings that are accessible to students, faculty, and staff. The goal is to assess areas where asbestos could be disturbed or present a risk to human health.

A) Roofing felts on a low walkway cover (portico) between classes - ✅ This is included in an AHERA survey, as roofing materials are often assessed for asbestos, particularly if they are in areas that could be disturbed during maintenance or repairs.

B) Transite panels on a roof-mounted exhaust duct from a woodshop - ✅ This is included in an AHERA survey. Transite panels (often containing asbestos) should be surveyed, especially in areas like woodshops where activities could potentially disturb the material.

C) Friable stucco on the columns supporting a covered walkway between classes - ✅ This is also included in an AHERA survey. Stucco containing asbestos in accessible areas (like walkways) must be assessed under AHERA.

D) Pipe lagging debris in a crawlspace which is never entered by students - ❌ This is not included in an AHERA survey.

AHERA surveys typically focus on materials that are accessible or could be disturbed by routine activities (e.g., areas frequented by students, faculty, or staff). Since the pipe lagging debris in a crawlspace is not accessible or disturbed by students, it might not be considered a priority for surveying under AHERA. However, if it were to be disturbed during construction or maintenance, it could still be a concern.

How often does the competent person need to be at the jobsite?

A. At least once daily

B. At all times

C. Not defined by regulations

B. At all times

Explanation:

Under OSHA regulations (specifically 29 CFR 1926.1101 for asbestos), a competent person must be present at the jobsite at all times when work involving asbestos is being conducted. The competent person is responsible for identifying and correcting hazardous conditions, ensuring that safety measures are followed, and managing the abatement process.

A) At least once daily - ❌ This is incorrect. The competent person is required to be on-site at all times while asbestos-related work is being conducted.

B) At all times - ✅ This is the correct answer. The competent person needs to be present at all times to monitor safety, oversee compliance, and address any potential hazards during asbestos work.

C) Not defined by regulations - ❌ This is incorrect. OSHA does define the requirement for a competent person to be present at all times during asbestos abatement work.

The following term related to the construction practice of installing main pipes, ducts, and mechanical equipment when a building's frame is first constructed, prior to fireproofing the building.

A. Rough-out

B. Rough-in

C. Rough-on

D. Rough-of

B. Rough-in

Explanation:

In construction, the term "rough-in" refers to the installation of main pipes, ducts, and mechanical equipment before the building's frame is finished and prior to fireproofing, drywall installation, or other finishing work. It typically happens early in the construction process.

A) Rough-out - ❌ This term is not commonly used in the context of installing systems during construction.

B) Rough-in - ✅ This is the correct term. It refers to the initial installation of systems like plumbing, electrical, and HVAC before the building is finished.

C) Rough-on - ❌ This is not a standard construction term.

D) Rough-of - ❌ This term does not apply in this context.

Adhesion refers to which of the following properties?

A. Tendency of a material to hold together or stick to itself

B. Tendency of a material to substrate

B. Tendency of a material to substrate

Explanation:

A) Tendency of a material to hold together or stick to itself refers to cohesion, not adhesion. Cohesion is the attraction between molecules of the same substance.

B) Tendency of a material to stick to a substrate is the correct definition of adhesion. Adhesion refers to the force that causes different substances (like glue to wood, or paint to metal) to stick together.

What is a homogeneous area under AHERA?

A. A group of rooms containing similar materials in similar condition

B. A room with only one material all of which is either "damaged" or extremely

"damaged"

C. A portion of a surfacing or miscellaneous material which is in the same condition, i.e. similar damage extent

D. An area of surfacing, miscellaneous, or thermal system insulation which is similar in color and texture.

D. An area of surfacing, miscellaneous, or thermal system insulation which is similar in color and texture.

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), a homogeneous area refers to a portion of a building where the asbestos-containing material (ACM) is similar in type, color, texture, and condition. This helps in organizing materials for sampling and assessment during an asbestos survey.

A) A group of rooms containing similar materials in similar condition: This is a more general description and not the definition of a homogeneous area under AHERA.

B) A room with only one material all of which is either "damaged" or extremely "damaged": This relates more to damaged materials, but it's not the definition of homogeneous areas.

C) A portion of a surfacing or miscellaneous material which is in the same condition, i.e., similar damage extent: This is somewhat related to condition but doesn't fully capture the concept of similarity in color, texture, and material type.

Under AHERA, an inspector sampling a TSI patching material which is approximately 5 square feet in size needs to collect a minimum of:

A. 1 sample

B. 3 samples

C. 5 samples

D. 1 sample and a quality control sample

B. 3 samples

Explanation:

Under AHERA regulations, when sampling a patch of thermal system insulation (TSI) that is approximately 5 square feet in size, the inspector must collect a minimum of 3 samples to ensure the material is adequately analyzed.

A) 1 sample: One sample is generally not sufficient for a material that is larger than a very small patch, like a 5-square-foot area.

C) 5 samples: While this may seem like an appropriate option for larger areas, it is not required under AHERA for a 5-square-foot patch of TSI.

D) 1 sample and a quality control sample: This is not the correct requirement for TSI under AHERA. Quality control samples may be taken, but this option is not the primary requirement.

The AHERA method recommends which of the following methods for dust sampling?

A. MicroVac sampling with a pump and cassette

B. Wet wipe sampling over a measured area

C. Removal of substrate for laboratory analysis under a microscope

D. None of the above.

A. MicroVac sampling with a pump and cassette

B. Wet wipe sampling over a measured area

Here's why:

AHERA (Asbestos Hazard Emergency Response Act) specifically addresses asbestos in schools and requires certain protocols for sampling. MicroVac sampling is a recognized method for collecting dust samples to analyze for asbestos content.

While wet wipe sampling (B) and substrate removal (C) are methods used for asbestos sampling in certain situations, MicroVac is the method that AHERA recomends for dust sampling.

Explanation:

Under AHERA regulations, wet wipe sampling is the recommended method for collecting dust samples over a measured area to evaluate asbestos dust in a building. This method is commonly used to sample dust on surfaces in areas where asbestos-containing materials (ACMs) have been disturbed or may be present.

A) MicroVac sampling with a pump and cassette: This is not the primary method recommended by AHERA for dust sampling, though it may be used in some circumstances.

C) Removal of substrate for laboratory analysis under a microscope: This is not typically how dust is sampled under AHERA. Wet wipe or air monitoring methods are more common.

D) None of the above: This option is incorrect because wet wipe sampling is indeed a recognized method under AHERA.

Cohesion refers to which of the following properties?

A. Tendency of a material to hold together or stick to itself

B. Tendency of a material to stick to a substrate

A. Tendency of a material to hold together or stick to itself

Explanation:

Cohesion refers to the internal attraction within a material, or the tendency of a material to stick to itself. This is the property that allows a substance to resist being broken apart or separated into pieces.

B) Tendency of a material to stick to a substrate refers to adhesion, not cohesion. Adhesion is the property that allows materials to stick to different surfaces or substrates.

When should AHERA recommend building inspections occur?

A. During normal school hours

B. During lunch breaks

C. During naptime

D. During nights or weekends

D. During nights or weekends

Explanation:

AHERA recommends that building inspections occur when school activities are not taking place to minimize exposure to asbestos-containing materials (ACMs) for students and staff. This is often during nights or weekends when the school is not in operation.

Under AHERA, how frequently must re-inspections by trained building inspectors occur?

A. Every six months

B. Every year

C. Every three years

D. Whenever material conditions deteriorate noticeably

C. Every three years

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), re-inspections of asbestos-containing materials (ACMs) in schools must be conducted by trained inspectors every three years. This ensures that any changes in the condition of the materials are properly assessed and managed.

Which of the following is an LEA responsibility under AHERA?

A. Notify temporary workers (exterminators, utility repair persons etc.) of the presence of

asbestos in the areas where they are working

B. Designate a person to ensure that requirements of the AHERA document are followed

C. Train workers to recognize asbestos and to protect themselves against it

D. All of the above

D. All of the above

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), the Local Education Agency (LEA) has several responsibilities to ensure the safety of individuals in and around schools with asbestos-containing materials (ACMs). These responsibilities include:

A. Notify temporary workers (exterminators, utility repair persons, etc.) of the presence of asbestos in the areas where they are working: LEAs must notify workers and contractors about the presence of asbestos in areas they will be working, so they can take necessary precautions.

B. Designate a person to ensure that requirements of the AHERA document are followed: LEAs must designate an individual, often referred to as the designated person, to ensure compliance with AHERA regulations and that appropriate actions are taken regarding asbestos management.

C. Train workers to recognize asbestos and to protect themselves against it: The LEA is responsible for ensuring that school maintenance and custodial staff, as well as contractors working in the building, receive appropriate training to safely handle or avoid asbestos.

AHERA requires this activity every six months in school buildings with known friable or suspected friable asbestos?

A. Wet cleaning using PPE

B. Air sampling by accredited individuals

C. Visual assessment by maintenance staff

D. Bulk sampling

C. Visual assessment by maintenance staff

Explanation:

Under AHERA (Asbestos Hazard Emergency Response Act), school buildings with known or suspected friable asbestos must have visual assessments performed every six months by trained or accredited maintenance staff. This is to monitor the condition of asbestos-containing materials (ACMs) and ensure they are not deteriorating or becoming a hazard.

A. Wet cleaning using PPE: Wet cleaning is required when cleaning asbestos debris or dust, but it is not specifically mandated every six months.

B. Air sampling by accredited individuals: Air sampling is not required every six months unless there is a known disturbance or during specific situations like abatement.

D. Bulk sampling: Bulk sampling is only done when necessary, such as when suspect materials need to be identified, not on a regular six-month schedule.

A functional space as defined by AHERA is...

A. A material with similar color and texture occurring in various areas throughout a building

B. A room or group of rooms with similar materials and conditions

C. An area comprising a single usage, such as classroom, gymnasium, etc., which is identified as having asbestos material in it.

D. A room or group of rooms designated by and accredited management planner or project designer, typically with a similar use (such as several classrooms/offices)

D. A room or group of rooms designated by and accredited management planner or project designer, typically with a similar use (such as several classrooms/offices)

According to AHERA, a "functional space" is defined as:

A room or group of rooms designated by and accredited management planner or project designer, typically with a similar use (such as several classrooms/offices)

Here's a breakdown of what that means and why the other options are less accurate:

The definition emphasizes that it's an area designated by accredited professionals. This is crucial for proper asbestos management.

It includes the possibility of a "group of rooms," acknowledging that asbestos hazards might span multiple areas with similar characteristics.

The phrase "similar use" indicates that the grouping isn't arbitrary but based on how the space is utilized.

In essence, a functional space is a defined area within a school building used for AHERA asbestos inspections and management.

"Significantly damaged" material as defined by UC Berkeley Extension (Not by AHERA)

constitute which of the following?

A. Evenly distributed damage over at least one tenth of the materials surface

B. One quarter of the materials surface damaged in a localized area

C. Asbestos debris has been generated by the material

D. All of the above

D. All of the above

Explanation:

"Significantly damaged" material, as defined by UC Berkeley Extension (but not by AHERA), includes all the following conditions:

A. Evenly distributed damage over at least one tenth of the material's surface: This indicates widespread damage over a substantial portion of the material.

B. One quarter of the material's surface damaged in a localized area: This condition highlights that a localized area is heavily damaged, and the damage exceeds a certain threshold (e.g., 25%).

C. Asbestos debris has been generated by the material: The generation of asbestos-containing debris, whether through damage or wear, is another indicator of significant damage.

All of these factors combined are used to classify the material as "significantly damaged" in the context defined by UC Berkeley Extension.

Which of the following is not required in an AHERA inspection report?

A. Name and signature of each accredited inspector who collected samples or made assessments

B. State of accreditation and accreditation number for each inspector

C. Exact locations where each bulk sample was collected

D. Assessments of friable and non-friable ACBM's

D. Assessments of friable and non-friable ACBM's

Explanation:

An AHERA inspection report does require:

A. Name and signature of each accredited inspector who collected samples or made assessments: The report should include this information to verify the qualifications and accountability of the inspectors.

B. State of accreditation and accreditation number for each inspector: This is necessary to ensure that the inspectors are properly accredited for the work they are conducting.

C. Exact locations where each bulk sample was collected: It is important to document where samples were taken so that there is a record of potential exposure risks and locations of asbestos-containing materials (ACM).

However, D. Assessments of friable and non-friable ACBM's is not explicitly required in the report. While identifying and assessing these materials is part of the inspection, AHERA primarily focuses on the sampling process and conditions of the materials rather than a full assessment of their status as friable or non-friable.

You enter a mechanical room and note an insulated tank. The tank is 12' long and 4' in diameter. How much insulation is on the tank?

A. 201 square feet

B. 251 square feet

C. 163 square feet

D. 176 square feet

D. 176 square feet.

Here's how to calculate the surface area of the cylindrical tank:

Understanding the Formula:

The total surface area of a cylinder is calculated by adding the area of the two circular ends and the area of the curved side.

The formula is: Total Surface Area = 2πr² + 2πrh, where: r = radius of the cylinder h = height (or length) of the cylinder π (pi) ≈ 3.14159

Applying the Values:

Diameter = 4 feet, so radius (r) = 2 feet

Length (h) = 12 feet

Calculation:

Area of the two ends = 2 π (2²) = 8π

Area of the curved side = 2 π 2 * 12 = 48π

Total surface area = 8π + 48π = 56π

56 * 3.14159 = 175.92904, which rounds to approximately 176 square feet.

Therefore the amount of insulation would be approximately 176 square feet.

The Federal level, which of the following agencies regulates asbestos?

A. EPA

B. Cal/OSHA

C. DOT

D. All of the above

D. All of the above

At the federal level, multiple agencies regulate asbestos:

EPA (Environmental Protection Agency): Oversees regulations for asbestos in buildings, water, air, and in the environment.

Cal/OSHA: Though Cal/OSHA operates at the state level in California, it is a part of OSHA's broader federal regulations regarding asbestos exposure in the workplace.

DOT (Department of Transportation): Regulates the transport of asbestos materials.

How much notification is required under NESHAPS prior to demolition of a building with

several thousand square feet of friable asbestos?

A. None

B. 10 days

C. 30 days

D. Annually

B. 10 days

Under the NESHAPS (National Emission Standards for Hazardous Air Pollutants), a notification must be provided to the EPA or the local air pollution control agency at least 10 days prior to demolition or renovation of a facility that contains friable asbestos. This notification includes information about the scope of the work and the presence of asbestos.

Which of the following is not a regulatory agency?

A. EPA

B. OSHA

C. NIOSH

D. They are all regulatory agencies

C. NIOSH

NIOSH (National Institute for Occupational Safety and Health) is not a regulatory agency. It is a research organization that provides recommendations for occupational safety and health standards but does not have enforcement authority.

On the other hand, the EPA (Environmental Protection Agency) and OSHA (Occupational Safety and Health Administration) are regulatory agencies with the authority to create and enforce regulations.

Cal/OSHA requires which of the-following licensing for abatement contractors?

A. Carcinogen user's registration

B. Asbestos contractor's registration

C. Both

C. Both

Here's why:

Asbestos Contractor's Registration: Cal/OSHA has specific regulations for asbestos abatement work, requiring contractors to be registered. This registration ensures that contractors meet certain safety and training standards.

Carcinogen User's Registration: Asbestos is a known carcinogen. Therefore, contractors working with asbestos are also required to have a carcinogen user's registration. This registration helps Cal/OSHA track and regulate the use of carcinogenic materials.
