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.  NO open flames. NO contact with hot surfaces.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Cough. Sore throat.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection if powder.  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. Convulsions. Drowsiness. Cough. Diarrhoea. Sore throat. Vomiting. Unconsciousness.  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 .

Physical dangers
 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive fumes. Reacts with acids. This produces toxic and corrosive fumes. 

Occupational exposure limits
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
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Ingestion could cause hypocalcaemia and hypokalaemia. This may result in central nervous system disorders and cardiac disorders. 

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