F80 Hazard Identification and Risk Assessment 2 — Questions and Answers
Question 1: Which hierarchy of controls is considered the MOST effective at eliminating workplace hazards?
- Administrative controls
- Personal protective equipment
- Elimination (Correct answer)
- Engineering controls
Correct answer: Elimination
Elimination physically removes the hazard from the workplace and is considered the most effective control measure.
Question 2: A job safety analysis (JSA) is primarily used to:
- Document worker injuries for insurance
- Identify hazards associated with specific job tasks before work begins (Correct answer)
- Assign blame after an incident occurs
- Calculate workers' compensation costs
Correct answer: Identify hazards associated with specific job tasks before work begins
A JSA breaks down a job into steps and identifies potential hazards for each step so they can be controlled proactively.
Question 3: What does the term 'residual risk' mean in the context of risk assessment?
- Risk that existed before any controls were applied
- Risk that remains after all control measures have been implemented (Correct answer)
- Risk transferred to a third-party contractor
- Risk associated only with chemical hazards
Correct answer: Risk that remains after all control measures have been implemented
Residual risk is the level of risk that remains after all practical control measures have been applied.
Question 4: Which of the following is an example of an ergonomic hazard?
- Exposure to benzene vapors
- Repetitive motion tasks on an assembly line (Correct answer)
- Slippery walking surfaces
- Electrical panel without a lock-out tag
Correct answer: Repetitive motion tasks on an assembly line
Ergonomic hazards involve physical stressors such as repetitive motions, awkward postures, and forceful exertions that can cause musculoskeletal disorders.
Question 5: In a risk matrix, if the severity of an injury is rated 'critical' and the probability is 'likely,' what is the typical risk level?
- Low
- Medium
- High (Correct answer)
- Negligible
Correct answer: High
A high severity combined with a high probability results in a high overall risk rating on a standard risk matrix.
Question 6: Which document is typically used to communicate chemical hazards to workers in the US?
- Job Hazard Analysis (JHA)
- Safety Data Sheet (SDS) (Correct answer)
- Incident Investigation Report
- Personal Protective Equipment Checklist
Correct answer: Safety Data Sheet (SDS)
Safety Data Sheets (SDS), required under OSHA's Hazard Communication Standard, provide detailed information about chemical hazards.
Question 7: What is the primary purpose of a 'near miss' report in a safety program?
- To discipline employees who almost caused an injury
- To identify hazards and prevent future incidents before an injury occurs (Correct answer)
- To calculate insurance premiums for the following year
- To satisfy legal requirements after an OSHA inspection
Correct answer: To identify hazards and prevent future incidents before an injury occurs
Near miss reporting identifies hazardous conditions and unsafe behaviors that could lead to injuries, enabling corrective actions before harm occurs.
