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 Nausea. Vomiting.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting. Abdominal pain.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink.

Chemical dangers
 

Occupational exposure limits
TLV: 2.5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2005).
MAK (inhalable fraction): 1 mg/m³; Peak limitation category: II(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
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the bones and teeth. This may result in fluorosis. Repeated or prolonged inhalation of dust particles may cause effects on the lungs.
