NFPA 10 Changes Extinguisher Maintenance

• After todays 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

• 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
