| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: ODOURLESS WHITE CRYSTALS OR POWDER. CHEMICAL DANGERS: The substance decomposes on heating above 100°C, on contact with strong bases, producing toxic and corrosive fumes including ammonia, nitrogen oxides and phosphorous oxides. The solution in water is a weak base. Reacts vigorously with strong acids and strong oxidants. Gradually gives off ammonia on exposure to air. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed, especially, if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes. | ||
