TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Explosive. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with combustable or reducing agents.
Water in large amounts. NO other extinguishing agents. In case of fire in the surroundings: use flooding amounts of water in the early stages.
EXPLOSION Risk of fire and explosion under confinement and high temperatures.

In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. Evacuate danger area.
EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• Cough. Headache. Sore throat (see Ingestion).
    		Local exhaust or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
  • EYES
    		• Redness. Pain.
    		Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Blue lips or fingernails. Blue skin. Convulsions. Diarrhoea. Dizziness. Vomiting. Weakness (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into non-combustible containers. Wash away remainder with plenty of water.
    		Provision to contain effluent from fire extinguishing. Separated from combustible and reducing substances. Dry.

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Heating may cause violent combustion or explosion. The substance decomposes on heating or on burning producing toxic fumes (nitrogen oxides). The substance is a strong oxidant and reacts with combustible and reducing materials.

    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 harmful 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. The substance may cause effects on the the blood , resulting in formation of methaemoglobin.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Decomposes below boiling point at c.a. 210°C
    Melting point: 170°C
    		 Relative density (water = 1): 1.7
    Solubility in water, g/100 ml at 20°C: 192
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to water.
    NOTES
    Becomes shock-sensitive when mixed with organic materials. Rinse contaminated clothes (fire hazard) with plenty of water.
