:
:
:
:

Water spray, Alcohol-resistant foam, Dry powder, Carbon dioxide, Sand.
Do not use a heavy water stream.
May induce explosion of containers by heating.
In case of fire, product may produce irritative or toxic fumes/gases.

:

Protection during firefighting:

If ignited, for the initial fire-fighting, cut off combustion sources, extinguishfire at a stroke using appropriate fire-extinguishers.
In the case of peripheral fire, quickly remove movable containers to safe
places.
If unable to be moved containers, sprinkle water to containers andsurrounding equipment, etc. to cool.
Avoid (reject) fire-fighting water to enter environment.
Even after extinguishing fire, thoroughly cool containers by using plenty ofwater.
Wear appropriate fire-resistant clothing including self containedcompressed air breathing apparatus.

6. Accidental release measures
Personal Precautions, Protective Equipment and Emergency Procedures
General measures: Before entering, ventilate the area.
Do not let unauthorized persons come close to the area.
Immediately place the leakage area in isolation, with taking proper
distances for all directions.
Wear appropriate personal protective devices to prevent inhalation andcontact with eye, skin, and clothing, and never attempt to work on the lee.
Environmental precautions
Environmental precautions:

Avoid release to the environment.
Prevent entry to sewers and public waters.
