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.

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.
