June 2012
CAS #: 7784-18-1Aluminium trifluoride
EINECS #: 232-051-1

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
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. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & 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. 

According to UN GHS Criteria

 

Transportation
UN Classification
 

STORAGE
Dry. Well closed. 
PACKAGING
 
ALUMINIUM FLUORIDE (ANHYDROUS) ICSC: 1324
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
HYGROSCOPIC WHITE OR COLOURLESS CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating and under the influence of moisture. This produces toxic and corrosive fumes including hydrogen fluoride (see ICSC 0283). 

Formula: AlF3
Molecular mass: 84.0
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  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of dust and by ingestion. 

Effects of short-term exposure
The aerosol is irritating to the eyes, skin and respiratory tract. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. 

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. 


Occupational exposure limits
TLV: 2.5 mg/m3, - ppm, as TWA; A4 (not classifiable as a human carcinogen).
MAK: 1 (inhalable, as Fluoride) mg/m3; peak limitation category: II(4).
MAK skin absorption (H).
pregnancy risk group: C 

ENVIRONMENT
 

NOTES
CAS 15098-87-0 and 32287-65-3 are for hydrated forms.
Temperature of decomposition is unknown in the 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.
