Combustible. Finely dispersed particles form explosive mixtures in air.
NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.
Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
PREVENT DISPERSION OF DUST!
Cough. Sore throat.
Use ventilation (not if powder), local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Wear safety spectacles, face shield or eye protection in combination with breathing protection if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
Rinse mouth. Rest. Refer for medical attention .
CLASSIFICATION & LABELLING
Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment. Personal protection: P2 filter respirator for harmful particles.
According to UN GHS Criteria
Transportation UN Classification
Separated from strong oxidants. Well closed.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE CRYSTALS OR FLAKES.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air.
Chemical dangers Decomposes on heating. Decomposes under the influence of strong oxidants. This produces acrid, toxic fume. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation.
Effects of short-term exposure The substance is mildly irritating to the skin and respiratory tract.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis under the influence of UV light.
OCCUPATIONAL EXPOSURE LIMITS
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
