EXPLOSION


EXPOSURE


  • INHALATION

    		• Local exhaust.
    		Fresh air, rest.
  • SKIN

    		• Protective gloves.
    		Rinse skin with plenty of water or shower.
  • EYES
    		• Redness. Pain.
    		Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION

    		• Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water (extra personal protection: P2 filter respirator for harmful particles)
    		Separated from strong oxidants, strong bases, strong acids. Keep in a well-ventilated room.

    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 (OELs):
     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.


    PHYSICAL
    PROPERTIES
    Decomposes below melting point at 100°C
    Relative density (water = 1): 1.6
    		 Solubility in water, g/100 ml at 10°C: 57.5
