media:
Specific hazards arising Explosion risk in case of fire. Fight fire remotely due to the risk of explosion.
from the chemical:Take care as it may decompose upon combustion or in high temperatures to
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: Keep containers cool by
spraying with water. Eliminate all ignition sources if safe to do so.
Special protectiveWhen extinguishing fire, be sure to wear personal protective equipment.

Section6. ACCIDENTAL RELEASE MEASURES
Personal precautions,Use extra personal protective equipment (P3 filter respirator for toxic particles). Keep
protective equipment and people away from and upwind of spill/leak. Entry to non-involved personnel should
emergency procedures: be controlled around the leakage area by roping off, etc.
Environmental precautions: Be careful not to let it flow into rivers, etc., since adverse effects on the environment
are concerned.

Section7. HANDLING AND STORAGE
Precautions for safe handling
Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment.
Prevent dispersion of dust. Keep away from heat. Wash hands and face thoroughly
after handling.
Use a closed system if possible. Use a local exhaust if dust or aerosol will be
generated.
Advice on safe handling: Avoid contact with skin, eyes and clothing.
May develop pressure. Open carefully.
Don't leave used equipment or rag. This product may ignite if it is left stuck on
combustibles such as paper, rags, etc.
Use corrosive resistant equipment.
Conditions for safe storage, including any
incompatibilities
Storage conditions:Keep container tightly closed. Store in a refrigerator.
Store locked up.
Be sure not to give the container unexpected impacts, such as falling down or falling
off.
Store away from combustibles.
Heat-sensitive, Light-sensitive
Packaging material:Comply with laws. Keep only in original container.

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: Dust respirator, self-contained breathing apparatus(SCBA), supplied air respirator,
etc. Use respirators approved under appropriate government standards and follow
local and national regulations.
Hand protection:Impervious gloves.
Eye protection:Safety goggles. A face-shield, if the situation requires.
Skin and body protection: Impervious protective clothing. Protective boots, if the situation requires.
