  1. Which type of sprinkler is required in rack storage applications where in-rack sprinklers are installed below the top tier?

    Answer: In-rack sprinklers with water shields

    NFPA 13 requires water shields (also called water barriers or shields) on in-rack sprinklers below the top level to prevent prewetting from upper sprinklers.

  2. A wet chemical suppression system is most commonly installed to protect which type of hazard?

    Answer: Commercial cooking equipment and hood systems

    Wet chemical systems (NFPA 17A) are specifically designed for commercial cooking equipment, suppressing grease fires through saponification.

  3. In a CO2 total flooding system, the minimum design concentration for protecting a Class B surface fire hazard per NFPA 12 is:

    Answer: 34%

    NFPA 12 requires a minimum CO2 concentration of 34% (by volume) for surface fire protection of Class B hazards.

  4. What does the term 'K-factor' represent in sprinkler system hydraulics?

    Answer: Sprinkler discharge coefficient relating flow to pressure

    The K-factor is the discharge coefficient in the formula Q = K√P, relating sprinkler flow (gpm) to operating pressure (psi).

  5. Under NFPA 750, water mist systems are classified by operating pressure. What pressure range defines a 'low-pressure' water mist system?

    Answer: Below 175 psi

    NFPA 750 defines low-pressure water mist systems as those operating at or below 175 psi (12.1 bar).

  6. When sizing a fire pump per NFPA 20, the pump must be capable of delivering what percentage of rated capacity at churn (no-flow) pressure not exceeding what limit?

    Answer: 0% rated flow; churn pressure ≤ 140% of rated pressure

    At churn (shutoff/no-flow) condition, NFPA 20 requires the net pump pressure not exceed 140% of the rated (design) pressure.

  7. Which suppression agent is best suited for protecting a normally occupied electronic equipment room due to its zero ozone depletion potential and low toxicity?

    Answer: HFC-227ea (FM-200)

    HFC-227ea has zero ozone depletion potential, low toxicity at design concentrations, and is safe for use in occupied spaces.
