  • INHALATION

    		• Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED!
    		Protective gloves. Protective clothing.
    		Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid.
  • EYES

    		• Face shield or eye protection in combination with breathing protection.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic fumes. Reacts violently with dimethyl formamide above 65°C.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.
    PDK: 0.9 mg/m3 (USSR 1982).


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Lungs may be affected by repeated or prolonged exposure. The substance may have effects on the liver, skin, and nervous system. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

    ENVIRONMENTAL
    DATA
         		In the food chain important to humans, bioaccumulation takes place, specifically in plants and fish. It is strongly advised not to let the chemical enter into the environment.
    NOTES
    Depending on the degree of exposure, periodic medical examination is indicated. Do NOT take working clothes home. Amatin, Anticarie, Bunt-cure, No Bunt 80, Sanocide, Sniecotox are trade names.
