F80 Fire Safety Procedures 3 — Questions and Answers
Question 1: What is the primary purpose of a fire watch?
- To observe fire training drills
- To monitor an area when fire protection systems are impaired (Correct answer)
- To inspect fire extinguisher labels monthly
- To count occupants during an evacuation
Correct answer: To monitor an area when fire protection systems are impaired
A fire watch is required when automatic fire suppression or detection systems are out of service, providing continuous human monitoring.
Question 2: Which fuel scenario represents a Class K fire hazard?
- A burning wooden pallet
- Gasoline spilled on a garage floor
- Hot cooking oil in a commercial fryer (Correct answer)
- Magnesium shavings in a machine shop
Correct answer: Hot cooking oil in a commercial fryer
Class K fires involve cooking oils and fats in commercial cooking equipment and require wet chemical suppression agents.
Question 3: How often must fire drills be conducted in most US office buildings under NFPA 101?
- Once every five years
- Once per year minimum (Correct answer)
- Once per quarter
- Monthly
Correct answer: Once per year minimum
NFPA 101 (Life Safety Code) generally requires at least one fire drill per year for business occupancies.
Question 4: What does a flashing red light on a smoke detector most commonly indicate?
- Normal standby operation (Correct answer)
- Low battery warning
- Active alarm condition
- Detector has been disabled
Correct answer: Normal standby operation
Most modern smoke detectors flash a red LED every 30–60 seconds during normal standby to show they are functioning.
Question 5: In a healthcare facility, which fire response strategy is used instead of full evacuation?
- Lockdown procedure
- Defend-in-place (shelter-in-place) (Correct answer)
- Vertical evacuation only
- Rapid assembly protocol
Correct answer: Defend-in-place (shelter-in-place)
Healthcare facilities use defend-in-place because moving bedridden patients during a fire may cause greater harm than staying in protected areas.
Question 6: Which extinguisher agent is safe to use on a Class A fire involving ordinary combustibles?
- Dry chemical (BC rated)
- Water (Correct answer)
- Carbon dioxide (CO2)
- Halon
Correct answer: Water
Water is effective on Class A fires (wood, paper, cloth) because it cools burning material below its ignition temperature.
Question 7: What is the correct response if a fire alarm sounds but no smoke or fire is visible?
- Investigate thoroughly before evacuating
- Silence the alarm and report it as a false alarm
- Evacuate the building as if the emergency is real (Correct answer)
- Call the alarm company before leaving
Correct answer: Evacuate the building as if the emergency is real
Every fire alarm must be treated as a real emergency; evacuation should begin immediately while emergency services are notified.
