  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion. See Chemical Dangers.    NO contact with incompatible materials: See Chemical Dangers  In case of fire in the surroundings, use appropriate extinguishing media.   

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Burning sensation. Cough. Laboured breathing. Shortness of breath. Vomiting. Drowsiness. Unconsciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer immediately for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles, 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. 
Ingestion Abdominal pain. Vomiting. Drowsiness.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO LIGHT. 

Physical dangers
 

Chemical dangers
Decomposes on heating or on burning and on contact with hot surfaces. This produces toxic and corrosive fumes of hydrogen bromide and bromine (see ICSC 0107). Reacts violently with powdered aluminium, powdered magnesium, calcium, strong bases and strong oxidants. This generates fire and explosion hazard. Attacks some forms of plastic, rubber and coatings.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the liver and kidneys. This may result in tissue lesions. Exposure at high concentrations could cause lowering of consciousness and death. The effects may be delayed. 

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

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver and kidneys, resulting in impaired functions. This substance is probably carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (skin); A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: skin absorption (H); carcinogen category: 2 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
