1. A manufacturing facility experiences a fatal incident involving a
forklift striking a pedestrian at an intersection inside the
warehouse. What should be the primary objective of the accident
investigation?
A. Assign blame to the forklift operator
B. Determine who violated company policy
C. Identify immediate and underlying causes to prevent recurrence
D. Calculate financial losses only
Answer: C. Identify immediate and underlying causes to prevent
recurrence
Rationale: The purpose of accident investigation is prevention, not
blame. Investigators identify direct, indirect, and root causes, evaluate
contributing organizational factors, and recommend corrective actions
that reduce the likelihood of similar incidents.
2. Which evidence is considered the most perishable during an
accident investigation?
A. Maintenance records
B. Employee training records
C. Witness memories
D. Equipment manuals
1
,Answer: C. Witness memories
Rationale: Human memory deteriorates rapidly and becomes influenced
by discussions, media exposure, and assumptions. Witness interviews
should occur as soon as practical after the incident.
3. Under the hierarchy of evidence, which source generally provides
the strongest support for determining accident sequence?
A. Rumors from coworkers
B. Physical evidence
C. Opinions of supervisors
D. Personal assumptions
Answer: B. Physical evidence
Rationale: Physical evidence—including skid marks, equipment
damage, debris patterns, and instrument readings—is objective and less
susceptible to bias than verbal testimony.
4. During scene preservation, the first priority after emergency
response is to:
A. Clean the work area immediately
B. Restore production
C. Secure and preserve the accident scene
D. Remove damaged equipment
Answer: C. Secure and preserve the accident scene
Rationale: Preserving the scene protects critical evidence from
contamination, alteration, or destruction while ensuring investigators
can reconstruct events accurately.

, 5. Root cause analysis differs from identifying immediate causes
because root cause analysis focuses on:
A. Employee injuries only
B. Organizational system failures
C. Equipment replacement costs
D. Insurance claims
Answer: B. Organizational system failures
Rationale: Immediate causes involve unsafe acts or conditions, while
root causes examine deficiencies in management systems, policies,
training, supervision, maintenance, and safety culture.
6. Which interviewing technique produces the most reliable witness
information?
A. Leading questions
B. Open-ended questions
C. Accusatory questioning
D. Rapid-fire questioning
Answer: B. Open-ended questions
Rationale: Open-ended questions encourage witnesses to describe
events naturally, reducing interviewer bias and increasing the accuracy
and completeness of testimony.
7. Which factor most commonly contributes to human error during
industrial accidents?
A. Random chance
B. Poor lighting only
C. Multiple interacting factors
D. Weather alone
3
, Answer: C. Multiple interacting factors
Rationale: Human error typically results from interacting
environmental, organizational, procedural, equipment, and
psychological factors rather than a single isolated issue.
8. Which accident investigation model emphasizes multiple layers of
defense failing simultaneously?
A. Domino Theory
B. Swiss Cheese Model
C. Pareto Principle
D. Maslow's Hierarchy
Answer: B. Swiss Cheese Model
Rationale: The Swiss Cheese Model explains accidents as the alignment
of weaknesses in multiple protective barriers, allowing hazards to pass
through organizational defenses.
9. In accident reconstruction, measurements should be:
A. Estimated visually
B. Based on witness guesses
C. Taken using calibrated measuring tools
D. Rounded significantly
Answer: C. Taken using calibrated measuring tools
Rationale: Accurate measurements ensure reliable reconstruction,
engineering analysis, and courtroom defensibility if litigation occurs.
10. Why should investigators avoid assigning fault early in the
investigation?
