Cheat Sheet

  1. Compartmentation by Fire Doors -

    Fire doors help combat fires because they seal gaps and maintain compartmentation, preventing smoke and flames from spreading. Remember the "TIGHT" mnemonic: Temperature-rated, Intumescent seals, Gravity-close, Heat response, Tested to UL 10C. According to NFPA 80, proper installation and rating are essential for effective compartmentation.

  2. High Expansion Foam Systems -

    High expansion foam systems flood large voids with low-density bubbles, displacing oxygen and suppressing fire quickly. Typical expansion ratios exceed 1,000:1, creating a blanket that conforms to stairwells and machinery spaces (NFPA 11). When reviewing high expansion foam systems questions, focus on generation rate, discharge time, and compatibility with hydrant or pump pressure.

  3. AFFF Application and Film Formation -

    Aqueous Film-Forming Foam (AFFF) forms a thin film that seals the fuel surface, blocking vapor release and extinguishing hydrocarbon fires within seconds. A standard 3% AFFF solution coverage rate is roughly 0.10 gal/ft² for medium-hazard areas (FM Global Data Sheet 3-13). In AFFF usage safety quiz scenarios, always confirm proportioner accuracy and environmental precautions.

  4. Integrated Fire Detection and Door Release -

    Fire detection systems test must verify that smoke or heat detectors trigger fire door closers within 30 seconds to limit fire growth (UL 864 standard). Linking door release to detection ensures a coordinated response: once an alarm is activated, doors automatically latch shut. When practicing for your fire inspection quiz, simulate detector activation to observe proper door operation.

  5. Routine Inspection and Maintenance -

    NFPA 80 and fire safety inspection practice call for monthly self-inspections of fire doors, checking clearances, hinges, seals, and latches. A quick checklist - door clearances ≤1/8″ top and sides, ≤¼″ under bottom, no missing hardware - ensures compliance. Document findings and remediate issues promptly to pass any fire inspection quiz and real-world audit.
