Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a lf-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gas may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Contact with metals may evolve flammable hydrogen gas.
Extinguishing Media:
U water spray, dry chemical, or carbon dioxide.
Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: U proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
