Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire. 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!
Fresh air, rest.
Rinse and then wash skin with water and soap.
Wear safety spectacles.
Rinse with plenty of water for several minutes (remove contact lenses if easily possible).
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 sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air.
Chemical dangers Decomposes on heating and on burning. This produces toxic and irritating fumes including hydrogen cyanide, nitrogen oxides and ammonia.
Formula: C3H6N6 / C3N3(NH2)3

Decomposes at 345°C Decomposes at 270°C Density: g/cm³ Solubility in water: poor Vapour pressure, Pa at 20°C: 6.7 Auto-ignition temperature: >500°C Octanol/water partition coefficient as log Pow: -1.14
EXPOSURE & HEALTH EFFECTS
Routes of exposure
Effects of short-term exposure
Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
Effects of long-term or repeated exposure
OCCUPATIONAL EXPOSURE LIMITS
Ingestion in large amounts may cause effects on the kidneys and bladder. This may result in stone formation.
