| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS OR WHITE POWDER. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes including hydrogen fluoride and ammonia. The solution in water is a weak acid. Reacts with chlorine trifluoride causing explosion hazard. Attacks glass and metal. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as fluorine) 2.5 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004). MAK: (as F) (Inhalable fraction) 1 mg/m³; Peak limitation category: I(4); skin absorption (H); Pregnancy risk group: C; (DFG 2005). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating 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 bones and teeth, resulting in fluorosis. | ||
