TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with flammable substances.
Water in large amounts. In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION
    		• Blue lips or finger nails. Blue skin. Burning sensation. Confusion. Convulsions. Cough. Dizziness. Headache. Laboured breathing. Nausea. Shortness of breath. Sore throat. Unconsciousness. Symptoms may be delayed (see Notes).
    		Local exhaust or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Redness. Skin burns. Pain. Blisters (further see Inhalation).
    		Protective gloves. Protective clothing.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
  • EYES
    		• Redness. Pain. Loss of vision. Severe deep burns.
    		Face shield, or eye protection in combination with breathing protection if powder.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Burning sensation. Shock or collapse (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from combustible and reducing substances. See Chemical Dangers. Keep in the dark. Well closed.

    PHYSICAL STATE; APPEARANCE:
     ODOURLESS, COLOURLESS TRANSPARENT OR WHITE CRYSTALS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic fumes including nitrogen oxides. The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts with incompatible substances such as acetylene, alkalies, halides and many other compounds causing fire and explosion hazard. Attacks some forms of plastics, rubber and coatings.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as Ag): ppm; 0.01 mg/m3 (ACGIH 1997).


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

    INHALATION RISK:
     Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. The substance may cause effects on the blood , resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the blood , resulting in formation of methaemoglobin. Inhalation or ingestion can lead to generalized argyria, a grey pigmentation of the skin and brown fingernails.
    PHYSICAL
    PROPERTIES
    Decomposes below boiling point at 444°C
    Melting point: 212°C
    		 Density: 4.35 at 19°C
    Solubility in water: very good
    ENVIRONMENTAL
    DATA
         		The substance is very toxic to aquatic organisms.
    N O T E S
    Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Rinse contaminated clothes (fire hazard) with plenty of water.
