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.

ALUMINIUM FLUORIDE (ANHYDROUS) ICSC: 1324
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC, WHITE OR COLOURLESS CRYSTALS

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) 1 mg/m³; Peak limitation category: I(4); skin absorption (H); Pregnancy risk group: C; (DFG 2005).
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

NOTES
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. Card has been partly updated in April and October 2005. See sections Occupational Exposure Limits, Emergency Response.
