F07 Fire Safety Equipment and Systems 2 — Questions and Answers
Question 1: How often should portable fire extinguishers in a commercial building typically be inspected?
- Every five years
- Annually only
- Monthly visual inspection plus annual maintenance (Correct answer)
- Only after use
Correct answer: Monthly visual inspection plus annual maintenance
NFPA 10 requires monthly visual inspections and annual maintenance checks of portable fire extinguishers to ensure they remain in operable condition.
Question 2: What does a flashing strobe light integrated into a fire alarm system primarily serve?
- It signals that the fire is located on an upper floor
- It provides visual notification for hearing-impaired occupants (Correct answer)
- It indicates the alarm system is in test mode
- It illuminates the path to the nearest exit
Correct answer: It provides visual notification for hearing-impaired occupants
Audible-visual notification appliances include strobes to alert hearing-impaired occupants who may not hear the audible alarm tones.
Question 3: During a fire drill, the conductor notices a fire door propped open. The correct action is to:
- Leave it open since it is only a drill
- Close the door immediately and document the violation (Correct answer)
- Report it to maintenance after the drill is complete
- Ignore it because no actual fire exists
Correct answer: Close the door immediately and document the violation
Fire doors must never be propped open as doing so compromises the building's fire and smoke compartmentalization; the conductor should close it and document the finding.
Question 4: Smoke detectors in a building are categorized by which two primary sensing technologies?
- Ionization and photoelectric (Correct answer)
- Thermal and ultraviolet
- Carbon monoxide and hydrogen
- Laser and infrared
Correct answer: Ionization and photoelectric
The two main types of smoke detectors are ionization (better for fast-flaming fires) and photoelectric (better for slow-smoldering fires), and both are commonly used in buildings.
Question 5: What is the significance of a fire extinguisher's PASS technique?
- Pull, Aim, Squeeze, Sweep — the steps to operate an extinguisher (Correct answer)
- Point, Activate, Spray, Stop — the steps for sprinkler override
- Prepare, Alert, Suppress, Secure — the fire response phases
- Pull, Alarm, Signal, Suppress — the drill conductor's steps
Correct answer: Pull, Aim, Squeeze, Sweep — the steps to operate an extinguisher
PASS stands for Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep side to side — the correct steps for operating a portable fire extinguisher.
Question 6: Emergency lighting in a building is required to provide illumination for a minimum of how long upon power failure?
- 30 minutes
- 60 minutes
- 90 minutes (Correct answer)
- 120 minutes
Correct answer: 90 minutes
NFPA 101 (Life Safety Code) requires emergency lighting systems to provide at least 90 minutes of illumination along egress paths following a power failure.
