F80 F80 Hazard Identification and Risk Assessment 2 — Questions and Answers
Question 1: Which of the following is the PRIMARY purpose of a Job Hazard Analysis (JHA) in fire prevention?
- To assign blame after an incident
- To systematically identify potential hazards associated with each step of a task (Correct answer)
- To determine insurance premiums for a facility
- To schedule routine maintenance activities
Correct answer: To systematically identify potential hazards associated with each step of a task
A Job Hazard Analysis breaks down tasks into individual steps to identify and mitigate potential hazards before they cause harm.
Question 2: When conducting a fire risk assessment, what does the term 'likelihood' refer to?
- The total cost of potential fire damage
- The probability that a fire hazard will result in an actual fire event (Correct answer)
- The number of occupants in a building
- The age of the fire suppression system
Correct answer: The probability that a fire hazard will result in an actual fire event
Likelihood in risk assessment refers to the probability that an identified hazard will lead to an adverse event such as a fire.
Question 3: A fire inspector identifies exposed electrical wiring near combustible storage materials. How should this be classified in a risk matrix?
- Low likelihood, low consequence
- High likelihood, high consequence (Correct answer)
- Low likelihood, high consequence
- No risk since wiring is common in buildings
Correct answer: High likelihood, high consequence
Exposed wiring near combustibles presents both a high probability of ignition and a high potential for serious fire damage.
Question 4: What is the MOST important factor to evaluate first when assessing fire risk in an occupied building?
- The color of the exit signs
- Life safety and occupant vulnerability (Correct answer)
- The brand of fire extinguishers installed
- The date of the last fire drill
Correct answer: Life safety and occupant vulnerability
Life safety and occupant vulnerability are always the highest priority in any fire risk assessment because protecting human life is paramount.
Question 5: Which hazard identification method involves tracing potential failure sequences from an initiating event to their consequences?
- Fault tree analysis
- Event tree analysis (Correct answer)
- Checklist inspection
- Pre-incident planning
Correct answer: Event tree analysis
Event tree analysis starts with an initiating event and maps out possible sequences of successes and failures to determine potential outcomes.
Question 6: During a risk assessment, an inspector finds that a warehouse lacks automatic sprinkler coverage. What type of risk factor does this represent?
- An ignition hazard
- A fuel load hazard
- A fire protection deficiency (Correct answer)
- An occupancy classification error
Correct answer: A fire protection deficiency
The absence of automatic sprinklers is a fire protection deficiency that increases the potential severity of a fire event.
