8. 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? NFPA 10 Changes & Extinguisher Maintenance

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

11. 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 NFPA 10 Changes & Extinguisher Maintenance

12. 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 NFPA 10 Changes & Extinguisher Maintenance

13. 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 NFPA 10 Changes & Extinguisher Maintenance
