supervisor during an emergency is classified as:
A) Policy statement
B) Procedure
C) Work instruction
D) Record‑keeping requirement
Answer: B
Explanation: Procedures describe the steps to be followed for specific actions, such as
emergency response duties.
**Question 5.** Which of the following best describes a “hazard” in occupational health and
safety terminology?
A) The likelihood that an incident will occur.
B) The potential source of injury or ill‑health.
C) The severity of an injury.
D) The frequency of workplace inspections.
Answer: B
Explanation: A hazard is any source or situation with the potential to cause harm.
**Question 6.** Noise exposure that exceeds 85 dB(A) over an 8‑hour workday is considered:
A) A non‑occupational hazard.
B) An ergonomic hazard.
C) A physical hazard requiring hearing conservation.
D) A chemical hazard.
, AIEHS Certified Health and Safety CHSP Exam
Answer: C
Explanation: Prolonged exposure above 85 dB(A) is a recognized occupational noise hazard that
mandates hearing protection programs.
**Question 7.** Which control hierarchy level is most effective for eliminating a chemical
hazard?
A) Engineering controls
B) Administrative controls
C) Personal protective equipment (PPE)
D) Substitution or elimination
Answer: D
Explanation: Substitution or elimination removes the hazard entirely, making it the most
effective control.

**Question 8.** When conducting a Job Safety Analysis (JSA), the first step is to:
A) Identify required PPE.
B) Break the job into sequential steps.
C) Evaluate the likelihood of injury.
D) Assign responsibility for each control.
Answer: B
Explanation: A JSA begins by dividing the task into discrete steps to later identify hazards for
each step.
**Question 9.** A qualitative risk assessment typically results in:
A) Numerical risk scores based on probability and impact.
, AIEHS Certified Health and Safety CHSP Exam
B) A color‑coded matrix describing risk levels (e.g., low, medium, high).
C) Exact monetary loss estimates.
D) Detailed exposure concentration values.
Answer: B
Explanation: Qualitative assessments use descriptive categories or color codes rather than
precise numerical values.
**Question 10.** Which of the following is a biological hazard commonly found in a
food‑processing plant?
A) Ultraviolet radiation.
B) Legionella bacteria in water systems.
C) Vibration from machinery.
D) Silica dust.
Answer: B

jurisdictions is:
A) 10 ppm (8‑hour TWA).
B) 1 ppm (8‑hour TWA).
C) 0.1 ppm (8‑hour TWA).
D) 5 ppm (8‑hour TWA).
Answer: B
Explanation: Regulatory agencies commonly set benzene’s PEL at 1 ppm as an 8‑hour
time‑weighted average.
