F80 F80 Hazard Identification and Risk Assessment 3 — Questions and Answers
Question 1: Which hierarchy of controls level provides the highest degree of protection against a workplace hazard?
- Administrative controls
- Engineering controls
- Elimination (Correct answer)
- Personal protective equipment
Correct answer: Elimination
Elimination physically removes the hazard from the workplace and is the most effective level of the hierarchy of controls.
Question 2: A maintenance worker notices a frayed electrical cord on a power tool. What is the FIRST action they should take?
- Wrap the cord with electrical tape and continue working
- Remove the tool from service and tag it out (Correct answer)
- Notify a coworker to watch for sparks
- Use the tool briefly to finish the current task
Correct answer: Remove the tool from service and tag it out
A damaged electrical cord is an immediate hazard; the tool must be removed from service and tagged out to prevent injury.
Question 3: What does a Job Hazard Analysis (JHA) primarily document?
- Employee performance metrics
- Hazards associated with each step of a job task (Correct answer)
- Equipment maintenance schedules
- Incident cost estimates
Correct answer: Hazards associated with each step of a job task
A JHA breaks a job into steps and identifies hazards and controls associated with each step.
Question 4: Which type of hazard is BEST described as a condition caused by repetitive motion, awkward posture, or excessive force?
- Chemical hazard
- Physical hazard
- Ergonomic hazard (Correct answer)
- Biological hazard
Correct answer: Ergonomic hazard
Ergonomic hazards arise from workplace factors such as repetitive motion, awkward postures, and forceful exertions that can cause musculoskeletal disorders.
Question 5: During a risk assessment, 'likelihood' refers to:
- The severity of injury if exposure occurs
- The number of employees exposed
- The probability that a hazard will cause harm (Correct answer)
- The cost to control the hazard
Correct answer: The probability that a hazard will cause harm
Likelihood (or probability) is the chance that a hazard will actually result in an adverse event or injury.
Question 6: Which document legally requires US employers with 11 or more employees to record work-related injuries and illnesses?
- OSHA 300 Log (Correct answer)
- NFPA 70E Standard
- ANSI Z10 Standard
- EPA Form R
Correct answer: OSHA 300 Log
OSHA 300 Log (and related forms 300A and 301) is the recordkeeping requirement under 29 CFR 1904 for qualifying employers.
Question 7: A chemical's Safety Data Sheet (SDS) Section 2 provides information about:
- First aid measures
- Hazard identification and classification (Correct answer)
- Physical and chemical properties
- Disposal considerations
Correct answer: Hazard identification and classification
SDS Section 2 (Hazard Identification) describes the hazards of the chemical and required label elements.
