fire fighting measures back to contents
【flash point】

121
【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. runoff from fire control or dilution water may cause pollution. extinguishing media: use agent most appropriate to extinguish fire. in case of fire, use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam.
【fire potential】

non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
