Combustible. Finely dispersed particles form explosive mixtures in air.
NO open flames. Prevent build-up of electrostatic charges (e.g., by grounding). Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.
In case of fire in the surroundings, use appropriate extinguishing media.
PREVENT DISPERSION OF DUST!
Cough. Sore throat.
Use 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.
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.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink.
CLASSIFICATION & LABELLING
Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.
According to UN GHS Criteria
Transportation UN Classification
Separated from strong oxidants.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS CRYSTALS.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc.
Chemical dangers Decomposes on burning. This produces toxic gases including nitrogen oxides. Reacts violently with oxidants.
Molecular mass: 133.1
Decomposes at 324°C Melting point: 270°C Density: 1.7 g/cm³ Solubility in water, g/100ml: 0.45 Octanol/water partition coefficient as log Pow: -3.89
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion.
Effects of short-term exposure The substance is irritating to the eyes and respiratory tract.
Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
Effects of long-term or repeated exposure
