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 protective When extinguishing fire, be sure to wear personal protective equipment.
equipment for firefighters:
Section 6. 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.
Prevention of secondary Do not allow contact with water. Remove all sources of ignition. Fire-extinguishing
hazards: devices should be prepared in case of a fire. Use spark-proof tools and explosion-
proof equipment.
Section 7. 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. Keep away from flames and hot surfaces. Take
measures to prevent the build up of electrostatic charge. Use explosion-proof
equipment. Wash hands and face thoroughly after handling.
Use a closed system, ventilation.
Advice on safe handling: Avoid contact with skin, eyes and clothing.
May develop pressure. Open carefully.
