Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 66°C explosive vapour/air mixtures may be formed. Finely dispersed particles form explosive mixtures in air.
NO open flames. Above 66°C use a closed system and ventilation. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.
Use water spray, powder, foam, carbon dioxide.
PREVENT DISPERSION OF DUST!
Cough. Sore throat. Further see Ingestion.
Use ventilation (not if powder), local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Wear safety spectacles or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Burning sensation in the throat and chest. Nausea. Vomiting. Diarrhoea. Headache. Confusion. Convulsions. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Artificial respiration may be needed. Refer for medical attention .
CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 4.1; UN Pack Group: III
Separated from strong oxidants, strong reducing agents, chlorinated solvents and food and feedstuffs. Well closed. Ventilation along the floor.
Do not transport with food and feedstuffs.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS OR WHITE CRYSTALS WITH CHARACTERISTIC ODOUR.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air.
Chemical dangers Decomposes on burning. This produces toxic gases and irritating fumes. Reacts violently with strong oxidants, strong reducing agents and chlorinated solvents. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion.
Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in convulsions and respiratory depression. Ingestion could cause death.
Inhalation risk A harmful contamination of the air will be reached on evaporation of this substance at 20°C.
Effects of long-term or repeated exposure
OCCUPATIONAL EXPOSURE LIMITS
