FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• Cough.
    		Ventilation (not if powder), local exhaust, or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
    		• Redness.
    		Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Nausea. Sore throat. Vomiting.
    		Do not eat, drink, or smoke during work. Wash hands before eating.
    		Rinse mouth. Give plenty of water to drink. Rest. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers. Wash away remainder with plenty of water (extra personal protection: P2 filter respirator for harmful particles).
    		Separated from ammonium nitrate, potassium chlorate, acids, alkalis, silver salts. Dry.

    PHYSICAL STATE; APPEARANCE:
     ODOURLESS, COLORLESS TO WHITE, HYGROSCOPIC SOLID IN VARIOUS FORMS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating or on burning, producing toxic and irritating fumes (nitrogen oxides, ammonia and hydrogen chloride). The solution in water is a weak acid. Reacts violently with ammonium nitrate and potassium chlorate causing fire and explosion hazard. Reacts with highly concentrated acids to form hydrogen chloride and with strong bases to form ammonia. Reacts with silver salts to form compounds that are sensitive to mechanical shock. Attacks copper and its compounds.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as fume): ppm; 10 mg/m3 (as TWA); 20 mg/m3 (as STEL) (ACGIH 1992-1993).
    OSHA PEL: none
    NIOSH REL: TWA 10 mg/m3 ST 20 mg/m3
    NIOSH IDLH: No data


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its dust or fume, and by ingestion.

    INHALATION RISK:
     Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin and the respiratory tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Sublimation point: 350°C
    Relative density (water = 1): 1.5
    		 Solubility in water: good (28.3 g/100 ml at 25°C)
    Vapour pressure, kPa at 160°C: 0.13
