large quantities; may catch fire.Temperature above flashpoint: higher fire/explosion hazard.
Highly flammable liquid and vapour.
Explosion hazard :May form flammable/explosive vapour-air mixture.
5.3. Advice for firefighters
Firefighting instructions :Use water spray or fog for cooling exposed containers. Exercise caution when fighting any
chemical fire. Avoid (reject) fire-fighting water to enter environment.
Protection during firefighting :Do not enter fire area without proper protective equipment, including respiratory protection.

large quantities; may catch fire.Temperature above flashpoint: higher fire/explosion hazard.
Highly flammable liquid and vapour.
Explosion hazard :May form flammable/explosive vapour-air mixture.
5.3. Advice for firefighters
Firefighting instructions :Use water spray or fog for cooling exposed containers. Exercise caution when fighting any
chemical fire. Avoid (reject) fire-fighting water to enter environment.
Protection during firefighting :Do not enter fire area without proper protective equipment, including respiratory protection.

SECTION 5:Firefighting measures
5.1. Extinguishing media
Suitable extinguishing media :Foam. Dry powder. Carbon dioxide. Water spray. Sand.
Unsuitable extinguishing media :Do not use a heavy water stream.

large quantities; may catch fire.Temperature above flashpoint: higher fire/explosion hazard.
Highly flammable liquid and vapour.
Explosion hazard :May form flammable/explosive vapour-air mixture.
5.3. Advice for firefighters
Firefighting instructions :Use water spray or fog for cooling exposed containers. Exercise caution when fighting any
chemical fire. Avoid (reject) fire-fighting water to enter environment.
Protection during firefighting :Do not enter fire area without proper protective equipment, including respiratory protection.
SECTION 6:Accidental release measures

Fire hazard :Heating increases the fire hazard. Heating may cause a fire. Heating may cause a fire or
explosion. Insufficient data available on direct fire hazard (flashpoint > 100 C). Self-heating in
large quantities; may catch fire.Temperature above flashpoint: higher fire/explosion hazard.
Highly flammable liquid and vapour.
Explosion hazard :May form flammable/explosive vapour-air mixture.
5.3. Advice for firefighters
Firefighting instructions :Use water spray or fog for cooling exposed containers. Exercise caution when fighting any
chemical fire. Avoid (reject) fire-fighting water to enter environment.
Protection during firefighting :Do not enter fire area without proper protective equipment, including respiratory protection.
SECTION 6:Accidental release measures
