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.
PREVENT DISPERSION OF DUST!
Cough. Sore throat.
Use ventilation (not if powder).
Fresh air, rest. Refer for medical attention.
Rinse skin with plenty of water or shower. Refer for medical attention .
Wear safety goggles.
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. Refer for medical attention .
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. Carefully collect remainder. Then store and dispose of according to local regulations.
According to UN GHS Criteria

Decomposes at 140°C Melting point: 135°C Density: 1.4 g/cm³ Solubility in water, g/100ml at 15°C: 0.25 (poor) Vapour pressure, Pa at 25°C: ~ 0.004 Octanol/water partition coefficient as log Pow: 1.19
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. Ingestion of large amounts could cause effects on the blood and central nervous system.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
Effects of long-term or repeated exposure Animal tests show that this substance possibly causes toxic effects upon human reproduction.
OCCUPATIONAL EXPOSURE LIMITS
