The Standard for Portable Fire Extinguishers
NFPA 10 is the Standard for Portable Fire Extinguishers, published by the National Fire Protection Association (NFPA). It provides minimum requirements for selecting, installing, inspecting, maintaining, recharging, and testing portable fire extinguishers to ensure they function effectively as a first line of defense against small fires. The current edition is 2022 (effective as of 2025), with the next edition (2026) introducing minor updates like electronic monitoring for monthly inspections and clarified disposal rules. Compliance is voluntary but widely adopted via building codes, OSHA (29 CFR 1910.157), insurance requirements, and local authorities having jurisdiction (AHJs).
NFPA 10 covers these core areas:
Choose extinguishers based on fire class (A: ordinary combustibles; B: flammable liquids; C: electrical; D: metals; K: kitchen oils). Match ratings (e.g., 2A:10B:C) to hazard size and type. Consider travel distance and area coverage.
Securely mounted, labeled, and accessible. Signs required if not visible from normal paths.
Annual: 6-year teardown for dry chemical; 12-year hydrostatic test. Record tag with date/tech ID.
Pressure test every 5–12 years (depending on type) to verify shell integrity.
Keep maintenance records (tags + logs). Train employees on use (PASS: Pull, Aim, Squeeze, Sweep).
NFPA 10 ensures extinguishers are ready—non-compliance risks fines ($1k+), insurance denial, or liability. For Red Zeppelin, your annual swaps exceed minimums (annual certification + records).
