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: Keep containers cool by
spraying with water but NO direct contact with water. Eliminate all ignition sources if
safe to do so.

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 dry sand or inert absorbent before recovering it into an
containment and cleaning airtight container. In case of large amount of spillage, contain a spill by bunding.
up: Adhered or collected 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.

Section7. HANDLING AND STORAGE
Precautions for safe handling
Handling is performed in a well ventilated place. Wear suitable protective equipment.
Technical measures:
Prevent generation of vapour or mist. Keep away from heat/sparks/open flame/hot
surfaces. -No smoking. 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 if possible. Use a ventilation, local exhaust if vapour or aerosol
will be generated.
Advice on safe handling:Avoid contact with skin, eyes and clothing.
Use well-dried equipment.
Handle under inert gas.
Don't leave used equipment or rag. This product may ignite if it is left stuck on
combustibles such as paper, rags, etc.
Conditions for safe storage, including any
incompatibilities
Storage conditions:Keep container tightly closed. Store in a cool, dark and well-ventilated place.
Store under inert gas.
Protect from moisture.
Store locked up.
Store away from incompatible materials such as oxidizing agents.
Moisture-sensitive
Packaging material:Comply with laws.
