International Chemical Safety Cards ALUMINIUM FLUORIDE (ANHYDROUS) ICSC: 1324 Aluminium trifluoride AlF3 Molecular mass: 84.0 ICSC #    1324 CAS #     7784-18-1 RTECS # BD0725000 UN #        1759 October 19, 1999 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE!  •INHALATION Cough. Shortness of breath. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Pain. Redness. Protective gloves. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Personal protection: P2 filter respirator for harmful particles. Separated from food and feedstuffs . Dry. Well closed. Do not transport with food and feedstuffs.

International Chemical Safety Cards ALUMINIUM FLUORIDE (ANHYDROUS) ICSC: 1324 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: HYGROSCOPIC , WHITE OR COLOURLESS CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes of fluorine. OCCUPATIONAL EXPOSURE LIMITS: TLV: (fluorides, as F) 2.5 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004). TLV: (as Al) 2 mg/m³ as TWA; (ACGIH 2004). MAK: (as F) (Inhalable fraction) 2.5 mg/m³; Peak limitation category: II(2); (DFG 2004). EU OEL: fluorides as F: 2.5 mg/m³ (EU 2004). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of the dust and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The aerosol is irritating to the eyes , the skin and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the bone, nervous system , resulting in bone alterations (fluorosis), and nervous system impairment. PHYSICAL PROPERTIES Sublimation point: 1272°C Density: 2.9 g/cm3 Solubility in water, g/100 ml at 20°C: 0.5 Vapour pressure, Pa at 1238°C: 133 ENVIRONMENTAL DATA N O T E S CAS 15098-87-0 and 32287-65-3 are for hydrated forms. Temperature of decomposition unknown in literature. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
