occupational health and safety (OH&S) policy?**
A) Clause 4.2
B) Clause 5.1
C) Clause 6.3
D) Clause 8.1
Answer: B
Explanation: Clause 5.1 of ISO 45001 specifies the requirements for leadership and worker
participation, including the establishment of an OH&S policy by top management.
**Question 2. In a positive safety culture, which indicator is most likely to be observed?**
A) High number of near‑miss reports
B) Low employee morale
C) Frequent disciplinary actions for safety violations
D) Minimal safety training sessions
Answer: A
Explanation: A high reporting rate of near‑misses shows that employees feel safe to report
hazards, indicating trust and a proactive safety culture.
**Question 3. Under OSHA’s General Duty Clause, an employer must provide a workplace that is
free from recognized hazards that are causing or are likely to cause what?**
A) Financial loss
B) Employee dissatisfaction
C) Death or serious physical harm
D) Legal disputes
Answer: C
, AIEHS Certified Workplace Health and
Safety CWHSP Exam
Explanation: The General Duty Clause (Section 5(a)(1)) requires employers to ensure a
workplace free from recognized hazards that could cause death or serious physical harm.
**Question 4. Which document is required to be kept for at least 30 years under OSHA’s
hazardous waste regulations?**
A) Safety Data Sheet (SDS)
B) Hazard communication poster
C) Hazardous waste manifest
D) Incident investigation report
Answer: C
Explanation: OSHA’s Hazardous Waste Operations and Emergency Response (HAZWOPER)
regulations require the hazardous waste manifest to be retained for a minimum of 30 years.
**Question 5. A leading indicator in occupational health and safety performance measurement
is:**
A) Lost‑time injury rate
B) Number of safety training hours delivered
C) Workers’ compensation claim cost
D) Frequency of recordable injuries
Answer: B
Explanation: Leading indicators predict future performance; training hours reflect proactive
safety efforts, unlike lagging indicators such as injury rates.
**Question 6. Which of the following is the most effective control in the hierarchy of
controls?**
A) Personal protective equipment (PPE)
B) Administrative procedures
, AIEHS Certified Workplace Health and
Safety CWHSP Exam
C) Engineering controls
D) Elimination of the hazard
Answer: D
Explanation: Elimination removes the hazard entirely, making it the most effective control,
followed by substitution, engineering, administrative, and PPE.
**Question 7. When conducting a Job Hazard Analysis (JHA), the first step is to:**
A) Evaluate the severity of each identified hazard
B) List the tasks involved in the job
C) Determine the appropriate PPE
D) Assign responsibility for corrective actions
Answer: B
Explanation: A JHA begins by breaking down the job into individual tasks, after which hazards
for each task are identified and assessed.
**Question 8. Which quantitative risk assessment method uses probability and consequence
matrices to calculate risk levels?**
A) Failure Mode and Effects Analysis (FMEA)
B) Fault Tree Analysis (FTA)
C) Risk Matrix scoring
D) Job Safety Analysis (JSA)
Answer: C
Explanation: A risk matrix assigns numerical values to probability and consequence, allowing
calculation of a risk rating.

**Question 9. Substituting a solvent with a lower toxicity level is an example of which control
level?**
A) Elimination
B) Substitution
C) Engineering control
D) Administrative control
Answer: B
Explanation: Substitution replaces a hazardous material with a less hazardous one, representing
the second tier in the hierarchy.
**Question 10. Which engineering control is most appropriate for controlling airborne dust
generated by a grinding operation?**
A) Local exhaust ventilation (LEV)
B) Safety signage
C) Mandatory PPE
D) Job rotation
Answer: A
Explanation: LEV captures dust at the source, reducing worker exposure to airborne
particulates.

A) An employee requests a new safety poster
B) A new piece of equipment is installed in the production line
C) A routine safety meeting is held
D) Annual safety training is completed
Answer: B
