  1. NFPA 10 Changes & Extinguisher Maintenance • Definitions: • Clean agent • Maintenance • 30 day inspections

  2. NFPA 10 Changes & Extinguisher Maintenance • Pressurized Fires • Liquids • Forced • Pumped • Sprayed

  3. NFPA 10 Changes & Extinguisher Maintenance • 1984: • Replace at next 6-year hydrostatic test • Does not apply to wheeled units • Fixed nozzle

  4. NFPA 10 Changes & Extinguisher Maintenance • Operating Instruction/Identification • Pictographic • Easier to identify • Standardized throughout the industry

  5. NFPA 10 Changes & Extinguisher Maintenance • Certified personnel • Factory trained • Certified by AHJ • Licensing

  6. NFPA 10 Changes & Extinguisher Maintenance • Maintenance Procedures: • Physical condition • Mechanical parts • Hoses on wheeled units

  7. NFPA 10 Changes & Extinguisher Maintenance • Maintenance Procedures • Rechargeable stored pressure dry chemical hand portable extinguishers

  8. NFPA 10 Changes & Extinguisher Maintenance After today’s presentation ask yourself Are we using the right fire extinguisher? Will it put out our fires? Are we keeping SAFETY our #1 priority?

  9. NFPA 10 Changes & Extinguisher Maintenance

  10. NFPA 10 Changes & Extinguisher Maintenance Combustible Metals – ease of ignition of thin sections, fine particles, or molten metal

  11. NFPA 10 Changes & Extinguisher Maintenance • Form of metal affects combustibility • Castings, blocks, billets, extrusions, etc. will not react or burn easily • Turnings & shavings will react more easily to water & ignition source • Powders may react to moist air, burn easily, even explode if airborne • The more finely divided, the easier to ignite

  12. NFPA 10 Changes & Extinguisher Maintenance • Heat from grinding, machining, sparks, or other burning fuels usually causes ignition in these metals • Most metals burn at very high temperatures • Relative slow progression of fire compared to Class “B” – closer to Class “A” rate • Toxic/caustic fumes • Once ignited most metals will react violently with water

  13. NFPA 10 Changes & Extinguisher Maintenance • Other fire considerations • Magnesium melts as it burns & may form puddles of molten magnesium – explosion hazards with water • Alkali metals react violently with halons • Detonation can occur in reaction between potassium and bromine in halons • Lithium will burn in nitrogen • Lithium fumes are more profuse & dense

  14. NFPA 10 Changes & Extinguisher Maintenance Magnesium Chips MET-L-X
