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. Extinguishing media: Use extinguishing media most appropriate for the surrounding fire. In case of fire, use carbon dioxide, dry chemical powder or appropriate foam.
