| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: GREY TO PURPLE CRYSTALS. CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides and hydrogen chloride. OCCUPATIONAL EXPOSURE LIMITS: TLV: (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2009). MAK: skin absorption (H); Carcinogen category: 2 (DFG 2009). |
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 when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver. This substance is possibly carcinogenic to humans. | ||
