Question 1
Scenario: A safety director at a manufacturing plant is
investigating why accidents continue to occur despite safety
training. She observes that each accident follows a predictable
sequence: management decisions, personal factors, unsafe acts,
unsafe conditions, and eventual injury.
Which accident causation theory best describes this chain-of-
events model?
A) Human Factors Theory
B) Domino Theory
C) Multiple Causation Theory
D) Systems Theory
,Page 2 of 92
Answer: B
Rationale: The Domino Theory, developed by Heinrich, views
accidents as a sequence of linked events or "dominoes."
Removing any single link (domino) in the chain prevents the loss.
The scenario explicitly describes a chain-of-events sequence,
which is the hallmark of this theory .
Question 2
Scenario: Your organization experienced one fatal injury this
quarter. According to Heinrich's Law, approximately how many
minor injuries would you expect to have seen leading up to this
event?
A) 10
B) 30
C) 100
D) 300
,Page 3 of 92
Answer: D
Rationale: Heinrich's Law, also known as the "300-30-1" ratio,
predicts that for every major injury (fatality), there are
approximately 300 minor injuries and 30 serious injuries. This
ratio helps safety directors understand that minor incidents are
precursors to major events .
Question 3
Scenario: During an ISO 45001 audit, the auditor asks you to
define the "context of the organization" as it relates to your
safety management system.
What should your response include?
A) Legal requirements only
B) Internal and external issues affecting safety
, Page 4 of 92
C) Employee grievances
D) Financial statements
Answer: B
Rationale: Under ISO 45001, "context of the organization"
refers to understanding both internal factors (organizational
culture, resources, knowledge) and external factors (legal,
technological, competitive, social) that influence the occupational
health and safety management system .
Question 4
Scenario: A chemical spill hazard has been identified in your
facility's laboratory. You are reviewing the Hierarchy of Controls
to determine the most effective intervention.
Which control level provides the highest level of protection?
