ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances.
NO contact with combustible substances and incompatible substances such as acetylene, alkalies, halides and other compounds.
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
STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

  • INHALATION
  • Burning sensation. Cough. Laboured breathing.
    Local exhaust or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Redness. Skin burns. Pain.
    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. Weakness.
    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. 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, organic and incompatible chemicals such as acetylene, alkalies, halides and other compounds. Cool. Keep in the dark. Keep in a well-ventilated room.
    Unbreakable packaging; put breakable packaging into closed unbreakable container.

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

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    Shock-sensitive compounds are formed with. The substance decomposes on heating producing toxic fumes (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 other compounds causing fire and explosion hazard. Attacks some forms of plastics, rubber and coatings. The substance decomposes on contact with organic contaminants when exposed to light.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV (as Ag): ppm; 0.01 mg/m3 (ACGIH 1991-1992).


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

    INHALATION RISK:
    Evaporation at 20C 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:
    Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The substance may have effects on the blood , resulting in forming 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 444C
    Melting point: 212C
    Relative density (water = 1): 4.3 at 19C
    Solubility in water: very good
    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to fish.
    NOTES
    Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. Rinse contaminated clothes (fire hazard) with plenty of water.
