📘 What Is NFPA 10?

NFPA 10 is published by the National Fire Protection Association, and it provides detailed requirements for how portable fire extinguishers should be managed in commercial and industrial settings. Most local fire departments and insurance companies reference NFPA 10 when conducting inspections or investigating incidents.


🔍 Key NFPA 10 Requirements for Business Owners

1. Extinguisher Placement and Accessibility

  • Must be mounted or placed where they are visible and accessible.
  • Travel distance should not exceed:
    • 75 ft for Class A hazards (ordinary combustibles)
    • 50 ft for Class B (flammable liquids) or Class K (kitchen fires)
  • Mounting height should be appropriate: no more than 5 ft from the floor for small units, and 3.5 ft for heavier units.

2. Proper Selection Based on Hazard Type

  • Class A: Paper, wood, cloth → Use water, foam, or ABC dry chemical
  • Class B: Flammable liquids → Use CO₂ or ABC dry chemical
  • Class C: Electrical fires → Use non-conductive extinguishers like CO₂ or ABC
  • Class D: Combustible metals → Use specialized Class D extinguishers
  • Class K: Commercial kitchen fires → Use wet chemical extinguishers

3. Monthly Inspections

  • Required to be done visually by the owner or designated staff.
  • Must check pressure gauge, location, accessibility, and condition.
  • Record inspection on a tag or log.

4. Annual Maintenance by Certified Technicians

  • A professional must inspect all units at least once a year.
  • Includes internal and external checks, labeling, seals, and service history.

5. Hydrostatic Testing

  • Conducted every 5 to 12 years, depending on the extinguisher type.
  • Tests the strength and integrity of the cylinder.
  • Performed by licensed technicians only.

⚠️ Why NFPA 10 Compliance Matters

  • Avoid Violations: Fire marshals often check for NFPA 10 compliance during inspections.
  • Protect Lives and Property: A properly maintained extinguisher can prevent a minor fire from becoming a disaster.
  • Insurance Validity: Non-compliance could affect your insurance claim after a fire.
