Combustible under specific conditions. Finely dispersed particles form explosive mixtures in air.
In case of fire in the surroundings, use appropriate extinguishing media.
PREVENT DISPERSION OF DUST!
Cough. Sore throat.
Use ventilation, local exhaust or breathing protection.
Fresh air, rest.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
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.
CLASSIFICATION & LABELLING
Sweep spilled substance into covered containers. Wash away remainder with plenty of water.
According to UN GHS Criteria
Transportation UN Classification
Separated from strong acids. Dry. Well closed.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance HYGROSCOPIC WHITE GRANULES OR CRYSTALLINE POWDER.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air.
Chemical dangers Decomposes on heating. This produces carbon monoxide (see ICSC 0023) and hydrogen (see ICSC 0001). This generates fire and explosion hazard. Decomposes on contact with acids. This produces formic acid vapours (see ICSC 0485).
Molecular mass: 68.0
Melting point: 253°C Density: 1.9 g/cm³ Solubility in water, g/100ml at 20°C: 97
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol.
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.
Effects of long-term or repeated exposure
