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, foam, powder, carbon dioxide.
PREVENT DISPERSION OF DUST!
Fresh air, rest.
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.
Do not eat, drink, or smoke during work.
CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.
According to UN GHS Criteria
Transportation UN Classification
Separated from strong oxidants.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WAXY WHITE SOLID IN VARIOUS FORMS.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air.
Chemical dangers Decomposes at 260°C. Decomposes on burning. This produces toxic fumes of nitrogen oxides. Reacts with strong oxidants.
Molecular mass: 593
Decomposes at 260°C Melting point: 135-146°C Relative density (water = 1): 0.97 Solubility in water: none Flash point: 280°C o.c.
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of dust.
Effects of short-term exposure The substance is mildly irritating to the eyes, skin and respiratory tract.
Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly , especially if powdered.
Effects of long-term or repeated exposure
