Suitable extinguishingDry chemical, carbon dioxide.
media:
Unsuitable extinguishing 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.
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
Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment.
Prevent generation of vapour or mist. 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.
Avoid contact with skin, eyes and clothing.
Advice on safe handling:

Section8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering controls:Install a closed system or local exhaust. Also install safety shower and eye bath.
Personal protective equipment
Respiratory protection: Half or full facepiece respirator, self-contained breathing apparatus(SCBA), supplied
air respirator, etc. Use respirators approved under appropriate government standards
and follow local and national regulations.
Impervious gloves.
Hand protection:
Eye protection:Safety goggles. A face-shield, if the situation requires.
Skin and body protection: Impervious protective clothing. Protective boots, if the situation requires.
