CFPS CFPS - Certified Fire Protection Specialist Fire Risk Assessment and Analysis Questions and Answers 1 — Questions and Answers
Question 1: In a quantitative fire risk assessment, which term describes the likelihood that a specific fire event will occur within a defined time period?
- Consequence severity
- Probability of ignition (Correct answer)
- Fire load density
- Suppression effectiveness
Correct answer: Probability of ignition
Probability of ignition quantifies the likelihood of a fire initiating event occurring within a specified period, forming the foundation of quantitative risk assessment.
Question 2: Which NFPA document provides guidance on fire risk assessment methodology for performance-based fire protection design?
- NFPA 13
- NFPA 72
- NFPA 551 (Correct answer)
- NFPA 101
Correct answer: NFPA 551
NFPA 551, Guide for the Evaluation of Fire Risk Assessments, provides the framework and methodology for conducting and evaluating fire risk assessments.
Question 3: A Failure Mode and Effects Analysis (FMEA) is used in fire risk assessment primarily to:
- Estimate fire suppression water demand
- Identify how individual component failures contribute to system risk (Correct answer)
- Calculate smoke layer descent time
- Determine egress travel distance
Correct answer: Identify how individual component failures contribute to system risk
FMEA systematically evaluates how each potential component failure mode affects overall system performance, helping identify critical vulnerabilities before they cause loss.
Question 4: In fire risk analysis, 'consequence' is best defined as:
- The probability that suppression will fail
- The adverse outcome resulting from a fire event (Correct answer)
- The number of ignition sources present
- The heat release rate of the fuel
Correct answer: The adverse outcome resulting from a fire event
Consequence refers to the adverse outcomes — such as deaths, injuries, or property loss — that result if a fire event occurs.
Question 5: Which analytical technique uses a tree diagram to trace all possible causes that could lead to a defined top-level fire event?
- Event tree analysis
- Fault tree analysis (Correct answer)
- HAZOP study
- Layer of protection analysis
Correct answer: Fault tree analysis
Fault tree analysis works backward from an undesired top event, using Boolean logic gates to map all combinations of failures that could cause that event.
Question 6: The risk matrix approach in fire risk assessment typically plots which two variables?
- Temperature vs. oxygen concentration
- Probability vs. consequence (Correct answer)
- Suppression flow rate vs. demand
- Egress time vs. population density
Correct answer: Probability vs. consequence
A risk matrix plots probability of occurrence on one axis and consequence severity on the other, enabling visual prioritization of risks.
