Special hazards arising from the substance or mixture
Special exposure hazards arising from the substance or preparation itself, its combustion products, or released gases Carbon oxides, Sulphur oxides.
Advice for firefighters Special protective equipment for firefighting
Personal protection through wearing a tightly closed chemical protection suit and a self-contained breathing apparatus.
Additional information on firefighting
Remove all sources of ignition. Pay attention to flashback. Suppress (knock down) gases/vapours/mists with a water spray jet. Do not allow run-off from fire fighting to enter drains or water courses.
Accidental release measures
Personal precautions
Keep people away from and upwind of spill/leak. Wear as appropriate: Complete suit protecting against chemicals
