ASP Fire Prevention and Protection 4 — Questions and Answers
Question 1: Which NFPA standard governs the installation of sprinkler systems in occupancies?
- NFPA 10
- NFPA 13 (Correct answer)
- NFPA 25
- NFPA 72
Correct answer: NFPA 13
NFPA 13 is the Standard for the Installation of Sprinkler Systems.
Question 2: A facility stores flammable liquids in a warehouse. Which NFPA code primarily governs the storage and handling of these liquids?
- NFPA 30 (Correct answer)
- NFPA 58
- NFPA 70
- NFPA 101
Correct answer: NFPA 30
NFPA 30, the Flammable and Combustible Liquids Code, governs storage, handling, and use of flammable and combustible liquids.
Question 3: What is the primary purpose of a pre-action sprinkler system compared to a wet-pipe system?
- It discharges faster than wet-pipe systems
- It prevents accidental water discharge before heat detection (Correct answer)
- It requires lower water pressure to activate
- It is used exclusively in outdoor environments
Correct answer: It prevents accidental water discharge before heat detection
Pre-action systems require a detection signal before water fills the pipes, preventing accidental discharge in areas with valuable equipment.
Question 4: During a fire inspection, an inspector finds that a fire door is propped open with a wooden wedge. What is the primary hazard of this practice?
- It reduces HVAC efficiency
- It allows fire and smoke to spread unchecked between compartments (Correct answer)
- It increases electrical hazard risk
- It violates ergonomic standards
Correct answer: It allows fire and smoke to spread unchecked between compartments
Fire doors are designed to compartmentalize fires; propping them open eliminates this passive protection and allows fire and smoke to spread.
Question 5: Which type of fire extinguisher is recommended for use on a Class K fire in a commercial kitchen?
- Dry chemical (ABC)
- Carbon dioxide (CO2)
- Wet chemical (Correct answer)
- Water mist
Correct answer: Wet chemical
Wet chemical extinguishers are specifically designed for Class K fires involving cooking oils and fats at high temperatures.
Question 6: A safety professional is evaluating fire hazards in a facility. What does the term 'ignition temperature' refer to?
- The temperature at which a liquid produces enough vapor to ignite with a spark
- The minimum temperature at which a substance will spontaneously ignite without an external ignition source (Correct answer)
- The temperature at which a fire extinguisher activates
- The temperature of flames in a fully developed fire
Correct answer: The minimum temperature at which a substance will spontaneously ignite without an external ignition source
Ignition temperature (autoignition temperature) is the minimum temperature required for spontaneous combustion without an external spark or flame.
Question 7: OSHA 29 CFR 1910.157 requires portable fire extinguishers to be inspected at what minimum frequency?
- Daily
- Weekly
- Monthly (Correct answer)
- Annually
Correct answer: Monthly
OSHA 1910.157 requires that portable fire extinguishers be visually inspected monthly to ensure they are in place and operational.
