The Fishbone (Ishikawa) Diagram
The 5-Why Analysis Model
The Domino Theory (Correct answer)
The Hierarchy of Controls Model

Correct answer: The Domino Theory

H.W. Heinrich's Domino Theory suggests that an accident is the result of a chain reaction of sequential events. The theory visualizes these events as dominos; if one falls, it triggers the next. By removing one of the dominos (i.e., addressing one of the causal factors), the sequence is interrupted, and the accident can be prevented.

Question 15: In an emergency, the primary purpose of establishing an Incident Command Post (ICP) is to:

House injured personnel awaiting medical transport
Provide a central location for command and coordination of tactical operations (Correct answer)
Conduct media briefings and public notifications

Question 23: According to OSHA's Hazard Communication Standard (29 CFR 1910.1200), when must an employer provide additional training to employees?

Annually for all chemical hazards present in the workplace.
Only when a new employee is hired.
Whenever a new type of chemical hazard is introduced into their work area. (Correct answer)
When the company updates its written Hazard Communication Program.

Correct answer: Whenever a new type of chemical hazard is introduced into their work area.

OSHA's Hazard Communication Standard at 29 CFR 1910.1200(h) requires employee training at the time of their initial assignment and whenever a new chemical hazard is introduced into their work area. The training does not need to be repeated annually, but it must be updated when new hazards appear.

Question 24: Which of the following is NOT an accepted method of fall protection for workers on low-slope roofs (slope ≤ 4:12) under OSHA construction standards?

Warning line system combined with safety monitoring system
Guardrail system
Warning line system alone without any other protection (Correct answer)
Personal fall arrest system

Correct answer: Warning line system alone without any other protection

A warning line system alone does not meet OSHA requirements; it must be combined with a safety monitoring system, PFAS, or guardrail on low-slope roofs.

Question 25: Under OSHA's Process Safety Management standard (29 CFR 1910.119), a Process Hazard Analysis (PHA) must be updated and revalidated at least every:

7 years
10 years
5 years (Correct answer)
3 years

Correct answer: 5 years

OSHA's PSM standard requires that PHAs be updated and revalidated at least every five years to reflect current process conditions and any changes.

Question 26: A safety supervisor is evaluating control measures for a newly identified hazard. According to the hierarchy of controls, which of the following actions should be considered the MOST effective?

Requiring employees to wear personal protective equipment.
Redesigning the equipment to remove the source of the hazard. (Correct answer)
Conducting monthly safety meetings on the new hazard.
Implementing a new work procedure to avoid the hazard.

Correct answer: Redesigning the equipment to remove the source of the hazard.

The hierarchy of controls ranks hazard control methods from most to least effective. Elimination, which involves physically removing the hazard, is the most effective measure. Redesigning the equipment to remove the source of the hazard is an example of an engineering control that aims to eliminate the hazard at its source. Administrative controls like new work procedures and safety meetings, and PPE are lower on the hierarchy and considered less effective.

Question 27: According to OSHA, how frequently must portable fire extinguishers be subjected to a formal annual inspection?

Monthly
Every 3 years
Annually (Correct answer)
Every 6 months

Correct answer: Annually

OSHA 1910.157 requires that portable fire extinguishers be subjected to an annual inspection by a qualified person, in addition to monthly visual checks.

Question 28: What is the primary difference between a workplace safety inspection and a safety management system audit?

Inspections are performed by external consultants, while audits are performed by frontline supervisors.
An inspection focuses on identifying physical hazards and unsafe acts, while an audit evaluates the design, implementation, and effectiveness of safety programs and policies. (Correct answer)
Inspections result in corrective action plans, whereas audits result in OSHA citations.
An inspection is a comprehensive annual review, while an audit is a brief daily check.

Correct answer: An inspection focuses on identifying physical hazards and unsafe acts, while an audit evaluates the design, implementation, and effectiveness of safety programs and policies.

A safety inspection is a physical check of the work environment to find hazards and at-risk behaviors. A safety audit is a systematic, high-level evaluation of the entire safety management system (e.g., training programs, recordkeeping, management commitment) to determine if it is effective and compliant.

Question 29: A supervisor at a construction site observes an employee using a damaged ladder to reach an elevated platform. This situation represents what type of workplace hazard?

Ergonomic Hazard
Safety Hazard (Correct answer)
Biological Hazard
Chemical Hazard

Correct answer: Safety Hazard

Safety hazards are unsafe working conditions that can cause injury, illness, or death. Examples include spills, blocked aisles, unguarded machinery, and working from heights on unsafe equipment like a damaged ladder. Ergonomic hazards relate to strain on the body, chemical hazards to harmful substances, and biological hazards to organic materials like bacteria or viruses.

Question 30: Under OSHA's Respiratory Protection standard (29 CFR 1910.134), which of the following is required BEFORE an employee uses a respirator?

A written supervisor approval
A fit test only
Both a medical evaluation and a fit test (Correct answer)
A medical evaluation only

Correct answer: Both a medical evaluation and a fit test
