7. Handling and storage
Handling
General advice:
Use with local exhaust ventilation. Avoid dust formation. Protect against moisture. Protect from air. Protect
from direct sunlight. Containers should be opened carefully in well-ventilated areas to avoid static discharge.
Protection against fire and explosion:
Take precautionary measures against static discharges. Sources of ignition should be kept well clear. Fire
extinguishers should be kept handy. Dust can form an explosive mixture with air.
Storage
General advice:
Keep container tightly closed in a cool, well-ventilated place. Keep under nitrogen.
Storage incompatibility:
General: Segregate from acids and acid forming substances.
Storage stability:
Protect against moisture.
8. Exposure controls and personal protection
Advice on system design:
Provide local exhaust ventilation to control dust.
Personal protective equipment
Respiratory protection:

for the respirator facepiece/cartridge combination.
Hand protection:
Chemical resistant protective gloves, Suitable materials, butyl rubber
Eye protection:
Tightly fitting safety goggles (chemical goggles) and face shield.
Body protection:
Protective coverall and/or impermeable apron and boots as necessary.
General safety and hygiene measures:
Avoid contact with the skin, eyes and clothing. Do not breathe dust. Eye wash fountains and safety showers
