    PHYSICAL STATE; APPEARANCE:
     BROWN POWDER.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating or on burning producing toxic fumes of arsenic and iron.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; 0.01 mg/m3 A1 (as TWA) (as As) (ACGIH 1994-1995).


    		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 when dispersed, especially if powdered.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the nervous system, liver, skin, kidneys and gastrointestinal tract , resulting in kidney impairment, neuropathy, severe gastroenteritis, degenerative liver damage and dermatitis. Exposure 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, gray skin and hyperkeratosis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the nervous system, liver, cardiovascular system and respiratory system , resulting in neuropathy, gangrene, degenerative liver damage and perforation of nasal septum. This substance is carcinogenic to humans.
    PHYSICAL
    PROPERTIES
    Solubility in water: none
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to plants, air and water. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
