  1. Under NFPA 13, what is the minimum required flow from the most hydraulically remote sprinkler in a light hazard occupancy using the density/area method at 0.10 gpm/sq ft over 1,500 sq ft?

    Answer: 13.0 gpm

    At 0.10 gpm/sq ft with a 130 sq ft coverage area per sprinkler (1,500/~11.5 sprinklers), the remote sprinkler must flow approximately 13 gpm to satisfy the density requirement.

  2. Which NFPA standard specifically addresses the inspection, testing, and maintenance of water-based fire protection systems?

    Answer: NFPA 25

    NFPA 25 is the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems.

  3. A kitchen hood suppression system discharges wet chemical agent and automatically shuts down the cooking equipment. Which NFPA standard governs this requirement?

    Answer: NFPA 17A

    NFPA 17A is the Standard for Wet Chemical Extinguishing Systems and requires automatic fuel and electrical shutoff upon system actuation.

  4. In high-expansion foam systems protecting a warehouse, what is the primary suppression mechanism?

    Answer: Flooding the space with foam to exclude oxygen and cool the fuel

    High-expansion foam (200:1 to 1,000:1) floods the protected volume, excluding oxygen and transferring heat through the foam's water content.

  5. What condition triggers the pressure switch alarm in a wet-pipe sprinkler system under normal operating circumstances?

    Answer: A drop in system water pressure caused by sprinkler discharge or waterflow

    A pressure switch (waterflow switch) in a wet-pipe system detects a pressure drop caused by water flowing through open sprinklers and activates the alarm.

  6. Per NFPA 2001, the minimum design concentration for HFC-125 (FE-25) protecting a Class A surface fire hazard is approximately:

    Answer: 8.7%

    NFPA 2001 specifies a minimum design concentration of 8.7% (volume) for HFC-125 on Class A surface fire hazards, based on cup-burner tests plus safety factor.

  7. When a fire pump is driven by a diesel engine per NFPA 20, what is the minimum fuel tank capacity required to operate the pump continuously?

    Answer: 6 hours at rated pump load

    NFPA 20 requires diesel-driven fire pump fuel tanks to hold sufficient fuel for at least 8 hours of operation at rated pump load.
