AIEHS Certified Health and Safety Manager
CHSM Exam
Question 1. Which of the following best describes the “Domino Theory” of accidents?
A) Accidents are caused by a single unsafe act.
B) Accidents result from a chain of events beginning with management decisions.
C) Accidents are random and cannot be predicted.
D) Accidents are solely the result of equipment failure.
Answer: B
Explanation: The Domino Theory posits that accidents follow a sequence of events, starting with
management decisions that create unsafe conditions, leading to unsafe acts and finally an
accident.
Question 2. In the hierarchy of controls, which control is considered the most effective?
A) Personal protective equipment (PPE)
B) Engineering controls
C) Administrative controls
D) Elimination
Answer: D
Explanation: Elimination removes the hazard entirely, making it the most effective control; all
other controls are less reliable.
Question 3. Which ISO standard specifies requirements for an occupational health and safety
management system?
A) ISO 9001
B) ISO 14001
C) ISO 45001
D) ISO 31000
Answer: C
, AIEHS Certified Health and Safety Manager
CHSM Exam
Explanation: ISO 45001 is the international standard for occupational health and safety
management systems.
Question 4. Under 29 CFR 1910, which part specifically addresses “General Workplace Safety
and Health” for all industries?
A) Subpart D – Walking‑Working Surfaces
B) Subpart G – Occupational Health and Environmental Controls
C) Subpart A – Scope, Definitions, and General Provisions
D) Subpart Z – Toxic and Hazardous Substances
Answer: C
Explanation: Subpart A provides the scope, definitions, and general provisions applicable to all
general industry workplaces.
Question 5. The primary purpose of an OSHA 300 Log is to:
A) Record all employee training hours.
B) Document work‑related injuries and illnesses.
C) List all safety inspections performed.
D) Track equipment maintenance schedules.
Answer: B
Explanation: The OSHA 300 Log records work‑related injuries and illnesses for reporting and
analysis.
Question 6. Which of the following is a biological occupational hazard?
A) Noise exposure
B. Lead dust
C. Legionella bacteria in cooling towers
, AIEHS Certified Health and Safety Manager
CHSM Exam
D. Vibration from hand tools
Answer: C
Explanation: Legionella is a microorganism that can cause disease when inhaled from
aerosolized water, making it a biological hazard.
Question 7. A “near‑miss” is defined as:
A) An incident that results in a minor injury.
B) An event that could have resulted in injury or loss but did not.
C) A documented safety training session.
D) A scheduled equipment shutdown.
Answer: B
Explanation: Near‑misses are events that had the potential for injury or damage but did not
actually cause harm.
Question 8. Which engineering control would most effectively reduce exposure to airborne silica
dust?
A) Providing respirators to workers.
B) Installing local exhaust ventilation at the source.
C) Rotating workers to limit time of exposure.
D) Posting warning signs.
Answer: B
Explanation: Local exhaust ventilation captures the dust at the source, reducing airborne
concentrations more effectively than PPE or administrative measures.
Question 9. The “Plan‑Do‑Check‑Act” (PDCA) cycle is primarily used for:
A. Conducting root‑cause investigations.
, AIEHS Certified Health and Safety Manager
CHSM Exam
B. Implementing continuous improvement in safety management.
C. Recording injury statistics.
D. Scheduling equipment inspections.
Answer: B
Explanation: PDCA provides a systematic framework for planning, executing, evaluating, and
improving safety processes.
Question 10. Which of the following best illustrates “duty of care” for a safety manager?
A) Ignoring a known hazard because production is down.
B) Providing adequate training and safe work procedures to employees.
C) Delegating all safety responsibilities to line supervisors.
D) Relying solely on employees to report unsafe conditions.
Answer: B
Explanation: Duty of care requires the manager to take reasonable steps, such as training and
procedures, to protect employees from harm.
Question 11. In a Job Hazard Analysis (JHA), the first step is to:
A) Identify the necessary personal protective equipment.
B) Break the job down into sequential steps.
C) Assign responsibility for each hazard.
D) Develop a corrective action plan.
Answer: B
Explanation: The initial step of a JHA is to list all the steps of the task to later analyze each for
hazards.
