Fire-fighting measures

Extinguishing media

Suitable: Dry chemical powder, Carbon dioxide (CO2), Foam, Sand

Special hazards arising from the substance or mixture: Water hydrolyzes material liberating acidic gas which in contact with metal surfaces can
generate flammable and/or explosive hydrogen gas.

 

Advice for firefighters:

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

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

 

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Precautions:       Avoid contact with spilled product or contaminated surfaces. Use personal protective equipment.

 

Environmental precautions

Do not allow to get into surface water, drains and ground water.
