TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Cough. Sore throat. Headache. Dizziness. Nausea. Abdominal pain.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles 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 See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes including carbonyl bromide and hydrogen bromide. Reacts with strong bases and strong oxidants. Attacks some metals such as aluminium, magnesium and zinc. Attacks some plastics, rubber and coatings. 

Occupational exposure limits
TLV (inhalable vapor and aerosol): 0.1ppm as TWA; (ACGIH 2008). 

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

Inhalation risk
A harmful contamination of the air will be reached rather slowly 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 and liver. This may result in impaired functions. 

Effects of long-term or repeated exposure
The substance may have effects on the liver.
