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 Risk of fire and explosion on contact with powdered metals. See Chemical Dangers.     
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Burning sensation. Cough. Laboured breathing. Shortness of breath. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Pain. Redness. Blisters.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Pain. Redness. Severe deep burns.  Wear face shield 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.

Physical dangers
 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive fumes of of hydrogen bromide (see ICSC 0282) and bromine (see ICSC 0107). Decomposes slowly under the influence of light and moisture. This produces corrosive hydrogen bromide. Reacts vigorously with powdered aluminium, powdered magnesium, metals such as sodium; potassium and calcium, strong bases and strong oxidants. This generates fire and explosion hazard. Attacks fats, rubber, some forms of plastic and coatings. 

Occupational exposure limits
TLV: (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: Carcinogen category: 2; Skin absorption (H); (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. 

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in lowering of consciousness. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause effects on the lungs. This may result in bronchitis. The substance may have effects on the liver and kidneys. This substance is probably carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
