Identification of Hazard and Risk Assessment Lecture

Question-and-Answer flashcards covering definitions, methods, risk matrix categories, control measures, hazard mapping value, and earthquake preparedness steps from the lecture notes.

What is hazard identification?

The process of determining all physical and non-physical agents in a workplace or specific environment that could cause harm.

What is risk assessment?

A method for prioritizing identified hazards based on the probability and severity of their potential impact.

List the four key steps in the hazard identification and risk-assessment cycle.

1) Identify the hazards 2) Assess the risk 3) Make changes (implement controls) 4) Check the changes made.

Name five common methods used to identify workplace hazards.

Observation, Material Safety Data Sheets (MSDS), Hazard and risk surveys, Discussion groups, and Safety audits.

In the Observation method, what tools are primarily used to detect hazards?

Sight, hearing, smell, and touch combined with knowledge and experience.

What information do Material Safety Data Sheets (MSDS) provide?

Possible harm from hazardous substances and the precautions that need to be taken when handling them.

What is the goal of a hazard and risk survey?

To interview people about their safety concerns, especially those who might be at special risk such as children or visitors.

How do discussion groups help in hazard identification?

They allow workers to collectively identify hazards and recommend practical solutions.

What is a safety audit?

A periodic, systematic inspection by an assigned committee to check safety conditions in an area.

In the risk matrix, what does the probability category "Almost Certain" imply?

Incidents of this nature are expected at least once a week.

Which probability value is assigned to "Almost Certain" in the matrix?

5

What does the probability category "Probable" signify?

Incidents are likely to occur at least once a month.

Which probability category covers incidents likely about once every three months?

Possible

Which probability category describes incidents that may happen roughly once in three years?

Rare

Which impact severity category represents severe loss of operational capability but survivable conditions?

Major

Which impact severity category indicates minimal, if any, operational impact?

Insignificant

Which severity category reflects complete operational failure and unsurvivable conditions?

Extreme

What are the three risk-priority levels used in the matrix?

Low, Moderate, and High.

Give one control measure recommended for the risk of hearing damage from loud noise.

Provide appropriate personal protective equipment (PPE) such as earplugs or earmuffs.

List two main purposes of hazard mapping in a community.

It shows areas vulnerable to specific hazards and supplies critical information for emergency planning and spatial development rules.

Name two preparedness actions to take BEFORE an earthquake occurs.

Check the structural integrity of buildings and prepare a first-aid or survival kit.

What safety protocol should you perform indoors during an earthquake?

Duck, Cover, and Hold on.

Why should elevators not be used during an earthquake?

Elevators can become stuck or fail, trapping occupants and increasing danger.

After an earthquake, why must you be prepared for aftershocks before re-entering buildings?

Aftershocks can further damage weakened structures, posing additional risk.

State one immediate action to do AFTER an earthquake to ensure safety.

Check yourself and others for injuries.

When on a beach during an earthquake, what should you do to reduce tsunami risk?

Move quickly to higher ground away from the coast.
