FIRE-FIGHTING MEASURES Suitable extinguishingDry chemical, foam, water spray, carbon dioxide. media: Unsuitable extinguishing Solid streams of water 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. When extinguishing fire, be sure to wear personal protective equipment. Special protective equipment for firefighters: Section6. ACCIDENTAL RELEASE MEASURES Personal precautions,Use extra personal protective equipment (self-contained breathing apparatus). Keep protective equipment and people away from and upwind of spill/leak. Ensure adequate ventilation. Entry to non- emergency procedures: involved personnel should be controlled 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. Section7. HANDLING AND STORAGE Precautions for safe handling Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment. Prevent generation of vapour or mist.
