Questions with Correct Verified Answers/ Rated A+
1. What is the primary goal of a system safety inspection?
a) To assign blame after an accident
b) To identify and mitigate hazards before they cause harm
c) To reduce production costs
d) To comply with insurance requirements
Correct Answer: b) To identify and mitigate hazards before
they cause harm
Rationale: System safety inspections are proactive measures
designed to identify potential hazards in equipment, processes,
and work environments before they result in injuries, property
damage, or operational disruptions. The goal is prevention, not
fault-finding .
2. What is the main difference between an inspection and an
audit?
1
,a) Inspections are more expensive than audits
b) Inspection checks physical conditions; audit checks the
management system
c) Audits are always conducted by external parties
d) There is no meaningful difference
Correct Answer: b) Inspection checks physical conditions;
audit checks the management system
Rationale: Inspections focus on identifying physical hazards and
unsafe conditions in the workplace. Audits evaluate the
effectiveness of the overall safety management system, including
policies, procedures, and documentation .
3. Which of the following is the correct hierarchy of hazard
controls (most to least effective)?
a) PPE → Engineering controls → Administrative controls →
Elimination
b) Elimination → Substitution → Engineering controls →
2
,Administrative controls → PPE
c) Administrative controls → PPE → Substitution → Elimination
d) Engineering controls → PPE → Elimination → Substitution
Correct Answer: b) Elimination → Substitution → Engineering
controls → Administrative controls → PPE
Rationale: The hierarchy of controls places elimination (removing
the hazard entirely) as most effective, followed by substitution
(replacing with something safer), engineering controls (physical
changes), administrative controls (policies and training), and PPE
(personal protective equipment) as the least effective but often
necessary control measure .
4. What does "ALARP" (As Low As Reasonably Practicable) refer
to?
a) A cost-cutting strategy
b) A risk management principle where risks are reduced to a
level tolerable given the cost and effort of further reduction
3
, c) A type of hazard control
d) An accounting standard
Correct Answer: b) A risk management principle where risks
are reduced to a level tolerable given the cost and effort of
further reduction
Rationale: ALARP is a key risk management principle used in
many safety regimes. It requires that risks be reduced to a level
that is as low as reasonably practicable, balancing the risk
reduction benefit against the cost, time, and effort of further
reduction measures .
5. What does "PHA" stand for in system safety?
a) Preliminary Hazard Analysis
b) Personal Hazard Assessment
c) Process Hazard Avoidance
d) Partial Hazard Allocation
Correct Answer: a) Preliminary Hazard Analysis
Rationale: Preliminary Hazard Analysis (PHA) is an initial step in
