TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation   Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. 

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. Carefully collect remainder. Then store and dispose of according to local regulations.   
EC Classification
 
UN Classification
 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
  Separated from mineral acids. 

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

Physical dangers
No data. 

Chemical dangers
On combustion, forms toxic fumes of fluoride. Reacts with mineral acids. This produces corrosive fumes. 

Occupational exposure limits
TLV: 2.5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (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 its aerosol and by ingestion. 

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

Effects of short-term exposure
 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 2500°C
Melting point: 1403°C
Density: 3.2 g/cm³
Solubility in water at 20°C: none 
 

NOTES
Calcium fluoride minerals are mined as fluorite and fluospar.
Card has been partly updated in April and October 2005.
