EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
  • Cough. Headache. Laboured breathing. Weakness (see Ingestion).
    Closed system and ventilation.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Redness. Pain.
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
  • Redness. Pain.
    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. Diarrhoea. Vomiting. Burning sensation behind breastbone and in the mouth.
    Do not eat, drink, or smoke during work. Wash hands before eating.
    Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Do NOT wash away into sewer. Vacuum spilled material. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles).
    Separated from strong oxidants, strong acids, food and feedstuffs. Cool. Well closed. Keep in a well-ventilated room.
    Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    WHITE POWDER.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating producing very toxic fumes of arsenic and lead. Reacts with oxidants. Reacts violently with strong acids.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV (as Pb): ppm; 0.15 mg/m3 (ACGIH 1992-1993).


    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 by dispersing.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance and the aerosol irritate the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system, digestive tract, circulatory system , resulting in severe haemorrhagic, losses of fluids and electrolytes, collapse, shock and death. Exposure at low level may result in death. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the peripheral nervous system, skin, mucous membranes, and liver , resulting in neuropathy, pigmentation disorders, perforation of nasal septum and cirrhosis. This substance is carcinogenic to humans.
    PHYSICAL
    PROPERTIES
    Relative density (water = 1): 5.85
    Solubility in water: none
    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to water organisms. In the food chain important to humans, bioaccumulation takes place, specifically in seafood. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
    N O T E S
    Temperature of decomposition unknown in literature. Do NOT take working clothes home.
