Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.
NO open flames. PREVENT DISPERSION OF DUST. Prevent build-up of electrostatic charges (e.g., by grounding).
Use water in large amounts.
Cough. Sore throat.
Use local exhaust.
Fresh air, rest.
Rinse skin with plenty of water or shower.
Wear safety spectacles.
Rinse with plenty of water (remove contact lenses if easily possible).

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE HYGROSCOPIC CRYSTALLINE POWDER WITH CHARACTERISTIC ODOUR.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air.
Chemical dangers Decomposes on heating. This produces toxic and corrosive fumes of sodium oxide. The solution in water is a weak base.
Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of long-term or repeated exposure See Notes.
OCCUPATIONAL EXPOSURE LIMITS
Health effects of exposure to the substance have been investigated, but none has been found.
