A company wants to determine the likelihood that a fire suppression system will fail on demand. Which technique is MOST appropriate?
Answer: Fault Tree Analysis (FTA)
Fault Tree Analysis uses Boolean logic to calculate the probability of a top-level system failure by tracing contributing component failures.
The concept of 'Defense in Depth' in risk control means:
Answer: Using multiple, independent layers of protection so no single failure causes an incident
Defense in Depth places multiple independent barriers between a hazard and harm so that a single barrier failure does not result in a loss.
Under ANSI/ASSP Z10.0, the primary purpose of the 'Check' phase in Plan-Do-Check-Act (PDCA) is to:
Answer: Evaluate whether implemented controls achieved desired safety performance
The Check phase measures actual results against planned objectives to determine whether controls are working as intended.
A 'Preliminary Hazard Analysis (PHA)' is MOST useful during which project phase?
Answer: Early concept or design stage
PHA is a high-level technique performed early in design when detailed information is limited but changes are least costly to make.
Which of the following is an example of an 'inherently safer design' strategy?
Answer: Reducing the inventory of flammable solvent stored on-site
Minimization — reducing hazardous material quantities — is one of the four inherently safer design strategies (Minimize, Substitute, Moderate, Simplify).
When a risk matrix plots 'Probability' on one axis and 'Severity' on the other, a hazard rated 'Moderate' probability and 'Critical' severity would typically require:
Answer: Documented acceptance by top management with interim controls
Moderate × Critical combinations typically fall in a 'high risk' zone requiring senior management acceptance and interim risk reduction before resuming full operations.
A 'what-if' analysis is BEST described as:
Answer: A structured team brainstorming technique that poses hypothetical deviation questions to identify hazards
What-If analysis uses structured team questions ('What if the pump fails?') to identify potential hazards and their consequences.
