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.  Use 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.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
 		PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.  Do not transport with food and feedstuffs. 
EC Classification
 
UN Classification
UN Hazard Class: 8; UN Pack Group: II 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-80GC10-II+III.  Separated from food and feedstuffs. Dry. Well closed. 

IMPORTANT DATA
Physical State; Appearance
HYGROSCOPIC WHITE OR COLOURLESS CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic fumes of fluorine. 

Occupational exposure limits
TLV (as F): 2.5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004).
TLV (as Al): 2mg/m³ as TWA; (ACGIH 2004).
MAK (inhalable fraction): 1 mg/m³; Peak limitation category: I(4); Pregnancy risk group: C; Skin absorption (H); (DFG 2005). 

Routes of exposure
The substance can be absorbed into the body by inhalation of 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, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause asthma. The substance may have effects on the bone and central nervous system. This may result 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/100ml 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.
Card has been partly updated in April and October 2005.
