Untitled

A laboratory that processes human tissues and body fluids into slides for microscopic examination.

Histopathology Laboratory

A medical healthcare provider who examines bodies and body tissues through performing lab tests.

Pathologist

An instrument used to view specimens by passing light through or reflecting it off the specimen.

Light Microscope

A contrast-enhancing microscope that improves the quality of the image obtained with birefringent materials.

Polarizing Microscope

An optical microscopy technique that converts small phase shifts in light passing through a transparent specimen into contrast changes in the images.

Phase-contrast microscope

A microscope used to observe unstained and transparent samples against a dark background.

Darkfield microscope

A microscope that uses fluorescence to generate an image.

Fluorescence microscope

A bladed instrument used to cut very fine sections of tissue for microscopic examination.

Microtome

A station where paraffin wax is placed for embedding tissue samples.

Embedding Station

Ovens used to quickly dry tissue samples.

Incubator Ovens

A bath used to float tissue sections on a water surface before placing them on microscope slides.

Floatation Bath

A device used to freeze tissue samples for preservation.

Freezer

A device used to store tissue samples at low temperatures.

Refrigerator

Instruments used to measure the acidity or alkalinity of a solution.

pH meters

An instrument used for quick heating or drying of samples.

Microwave

An instrument used to measure the weight of samples or reagents.

Weighing scale

Devices used to warm microscope slides before staining or examination.

Slide warmers

Measures taken to ensure the safe handling and storage of chemicals in the laboratory.

Chemical Safety

Chemicals that cause reversible inflammatory effects in living tissues.

Irritants

Chemicals that cause destruction in living tissue or certain inanimate surfaces.

Corrosive

Chemicals that cause allergic reactions in some exposed workers.

Sensitizers

Substances that induce tumors in experimental animals and humans.

Carcinogen

Chemicals that can readily ignite and burn.

Flammable

Chemicals capable of causing death by ingestion, skin contact, or inhalation at certain concentrations.

Toxic

Chemicals that may initiate combustion and present a serious fire risk when in contact with certain substances.

Explosive

The process of properly labeling chemical containers with relevant information such as chemical names, manufacturer's name and address, date purchased and opened, expiration date, and hazard warnings.

Labeling

Proper procedures for handling chemical spills, including not mopping the spill, identifying the type of chemical spilled, and using cat litter to absorb the spill.1. Formalin:A chemical compound used as a preservative in laboratories, but it is also a human carcinogen and can cause allergies and irritation.

Handling Spill

Objects that can cause accidents if not handled properly, such as getting stuck with a needle. Following safety rules can help prevent accidents.

Sharps and Needles

Hazards brought by machines and equipment used in the laboratory, such as broken or leaking glassware. Improper handling and manipulation of equipment can also be dangerous.

Machines

Not maintaining a safe and organized working area can lead to accidents. It is important to clean the working area throughout the day and before leaving the lab.

Poor Housekeeping

Refers to anything that can cause disease in humans, including infectious agents, toxins, and contaminated solutions or objects. Protective gear should be used, and biological materials should not be stored in hallways or unlocked freezers.

Biological Safety

Faulty electrical equipment, damaged connectors, and improper use of extension cords can lead to shocks or electrocutions. It is important to receive training and use proper equipment.

Electrical Safety

Personnel should receive training on fire safety. Flammable materials should be handled with caution, and prevention measures should be taken to avoid fires.

Fire Safety

In the context of sentinel lymph node biopsies, a specific amount of technetium-sulfur colloid is used. Proper disposal procedures should be followed, such as double bagging.

Radiation Safety

Laboratory work activities can introduce ergonomic risk factors that can lead to muscular-skeletal disorders. Factors include posture, repetitive movements, excessive force, contact stresses, and vibrations.

Ergonomic Safety

The process of ensuring and maintaining personal and environmental health and safety in the laboratory.

Risk Management

Written procedures mandated by accrediting or regulatory agencies to ensure laboratory safety.

Standard Operating Procedures (SOPs)

Files containing information about hazardous chemicals, which should be readily accessible in the laboratory.
