| Fire Fighting Measures | Back to Contents | 【Flash Point】
235 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use extinguishing media appropriate to the surrounding fire. Substance is nonflammable. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Extinguishing media: Substance is nonflammable; use agent most appropriate to extinguish surrounding fire. Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam. | 【Fire Potential】
Nonflammable |
