  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Heating will cause rise in pressure with risk of bursting.  Risk of fire and explosion on contact with water. Risk of fire and explosion as a result of decomposition when heated.  NO contact with water or steam. NO contact with hot surfaces.    In case of fire in the surroundings, use appropriate extinguishing media. NO water.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 

 STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Shortness of breath. Sore throat. Burning sensation. Laboured breathing. Symptoms may be delayed. See Notes.  Use ventilation. Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Skin burns. Pain. Blisters.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain. 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. 
Ingestion Abdominal cramps. Burning sensation. Weakness. Diarrhoea. Vomiting. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS FUMING LIQUID WITH PUNGENT ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
May explode on heating. Decomposes on contact with alcohol. This produces toxic and corrosive fumes of hydrogen bromide. Reacts with water. This produces hydrogen bromide gas. This generates explosion hazard. 

Formula: BBr3
Molecular mass: 250.5
Boiling point: 91°C
Melting point: -46°C
Relative density (water = 1): 2.7
Solubility in water: reaction
Vapour pressure, kPa at 14°C: 5.3
Relative vapour density (air = 1): 8.6
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.4 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema. See Notes. 

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
 


Occupational exposure limits
TLV: 0.7 (ceiling) ppm as STEL 

ENVIRONMENT
 

NOTES
Reacts violently with fire extinguishing agents such as water or foam.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
The odour warning when the exposure limit value is exceeded is insufficient.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do NOT take working clothes home.
