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      
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Reacts with acids. This produces hydrogen fluoride. Reacts violently with chlorine. This generates fire hazard. 

Occupational exposure limits
TLV: 2mg/m³ as TWA; (ACGIH 2004). 

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
Corrosive on ingestion. The substance is irritating to the eyes. 

Effects of long-term or repeated exposure
The substance may have effects on the teeth and bones (fluorosis). 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 850°C
