Section5. FIRE-FIGHTING MEASURES
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.

Section7. HANDLING AND STORAGE
Precautions for safe handling
Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment.
Be careful not to cause leakage, overflow, or dispersion. Steam should not be
generated unnecessarily. 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. Avoid shock and friction. Wash hands and face before
breaks and immediately after handling the product.
Use a closed system if possible. Use a local exhaust if dust or aerosol will be
generated.
Advice on safe handling: Avoid all contact!
Conditions for safe storage, including any
incompatibilities
Storage conditions:Keep container tightly closed. Store in a cool, dark and well-ventilated place.
Store locked up.
Be sure not to give the container unexpected impacts, such as falling down or falling
off.
Store away from incompatible materials such as oxidizing agents.
Comply with laws.

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.
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.
