Fire-fighting measures

- Suitable extinguishing media:

Water spray, Alcohol-resistant foam, Dry chemical, Carbon dioxide (CO2)

- Special hazards arising from the substance or mixture:

Vapours are heavier than air and may spread along floors. The product is combustible. In the event of fire the following may be released: Hydrogen fluoride, Nitrogen oxides (NOx), Carbon monoxide (CO), Carbon dioxide (CO2)

- Advice for fire fighter:

Special protective equipment for firefighters: In the event of fire and/or explosion do not breathe fumes. Wear self-contained breathing apparatus and protective suit.

Further information: Contain the spread of the fire-fighting media. Do not allow run-off from fire fighting to enter drains or water courses
