Incompatibilities
Strong oxidizing agents, moisture, strong acids.
Decomposition
Irritating and toxic fumes and gases, hydrogen fluoride, fluorine.

Fire.
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. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
