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: all extinguishing agents allowed.
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	PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. (Extra personal protection: P2 filter respirator for harmful particles).	UN Hazard Class: 8 UN Pack Group: II	Do not transport with food and feedstuffs.

EMERGENCY RESPONSE	STORAGE
Transport Emergency Card: TEC (R)-80G18	Separated from food and feedstuffs. Dry. Well closed.

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 (ACGIH 1999).
TLV (as Al): 2 mg/m³ (ACGIH 1999).
fluorides as F : 2.5 mg/m³ EC OELs

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 irritates 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	ENVIRONMENTAL DATA
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

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.
