F80 F80 Hazard Identification and Risk Assessment 5 — Questions and Answers
Question 1: When inspecting a warehouse and you notice liquid spilled on the floor with no wet floor signs posted, which hazard category does this fall under?
- Biological hazard
- Safety hazard (slip/trip/fall) (Correct answer)
- Ergonomic hazard
- Chemical hazard
Correct answer: Safety hazard (slip/trip/fall)
Uncontrolled liquid spills create slip, trip, and fall hazards, which are classified under safety hazards.
Question 2: A risk assessment determines that a hazard has a 'critical' severity rating. Which action is most appropriate?
- Schedule corrective action for the next quarterly review
- Accept the risk and document it
- Implement immediate interim controls while developing permanent controls (Correct answer)
- Monitor the hazard monthly
Correct answer: Implement immediate interim controls while developing permanent controls
Critical severity hazards require immediate interim controls to protect workers while permanent engineering or elimination solutions are developed.
Question 3: Which OSHA General Duty Clause obligation applies to ALL employers regardless of specific standards?
- Provide free safety training annually
- Furnish a workplace free from recognized hazards likely to cause death or serious harm (Correct answer)
- Conduct monthly fire drills
- Supply all PPE at no cost to employees
Correct answer: Furnish a workplace free from recognized hazards likely to cause death or serious harm
Section 5(a)(1) of the OSH Act (General Duty Clause) requires every employer to provide a workplace free from recognized serious hazards even when no specific standard applies.
Question 4: During hazard identification, 'change analysis' is used to evaluate:
- Employee turnover impact on safety
- New or modified processes, equipment, or materials for introduced hazards (Correct answer)
- Seasonal variation in injury rates
- Budget changes for the safety department
Correct answer: New or modified processes, equipment, or materials for introduced hazards
Change analysis (or Management of Change) systematically reviews modifications to processes, equipment, or chemicals to identify new hazards before implementation.
Question 5: Which statement best describes 'residual risk'?
- Risk that exists before any controls are applied
- Risk that remains after all feasible controls have been implemented (Correct answer)
- Risk transferred to an insurance carrier
- Risk associated with emergency scenarios only
Correct answer: Risk that remains after all feasible controls have been implemented
Residual risk is the level of risk that remains after all practicable control measures have been put in place.
Question 6: A supervisor asks workers to identify hazards on their own before starting a new task. This practice is called:
- Incident investigation
- Pre-task hazard assessment (Correct answer)
- Corrective action planning
- Safety committee review
Correct answer: Pre-task hazard assessment
A pre-task hazard assessment (also called a pre-job hazard analysis or take-five) is a worker-led evaluation of hazards before beginning work.
Question 7: Which regulatory body sets permissible exposure limits (PELs) for chemical hazards in US workplaces?
- EPA
- CDC
- OSHA (Correct answer)
- NIOSH
Correct answer: OSHA
OSHA establishes and enforces Permissible Exposure Limits (PELs) for chemical hazards under 29 CFR 1910.1000 and substance-specific standards.
