Section5. FIRE-FIGHTING MEASURES
Suitable extinguishingDry chemical, foam, carbon dioxide.
media:
Unsuitable extinguishing Water (It may scatter and spread fire.)
media:
Specific hazards arising Take care as it may decompose upon combustion or in high temperatures to
from the chemical:generate poisonous fume.
Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing
method according to the surrounding situation is used. Uninvolved persons should
evacuate to a safe place. In case of fire in the surroundings: Remove movable
containers if safe to do so.
Special protectiveWhen extinguishing fire, be sure to wear personal protective equipment.
equipment for firefighters:

Section6. ACCIDENTAL RELEASE MEASURES
Personal precautions,Use personal protective equipment. Keep people away from and upwind of spill/leak.
protective equipment and Ensure adequate ventilation. Entry to non-involved personnel should be controlled
emergency procedures: around the leakage area by roping off, etc.
Environmental precautions: Prevent product from entering drains.
Methods and materials for Absorb spilled material in a suitable absorbent (e.g. rag, dry sand, earth, saw-dust).
containment and cleaning In case of large amount of spillage, contain a spill by bunding. Adhered or collected
up: material should be promptly disposed of, in accordance with appropriate laws and
regulations.
