SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Inhalation causes severe irritation of mucous membranes. Ingestion causes burns of mouth and stomach. Contact with eyes or skin causes severe burns. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
The symptoms of lung edema 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.
SECTION 5: Firefighting measures
Suitable extinguishing media
Extinguish fire using agent suitable for surrounding fire. Use dry chemical, or carbon dioxide. DO NOT use water. Violent reaction may result.
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Toxic fumes of the chemical or hydrogen bromide may form in fires. (USCG, 1999)
Special protective actions for fire-fighters
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.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
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.
Environmental precautions
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.
Methods and materials for containment and cleaning up
Releases may require isolation or evacuation. Keep water away from release. Stop or control the leak, if this can be done without undue risk. Approach release from upwind. Absorb in noncombustible material for proper disposal.
SECTION 7: Handling and storage
Precautions for safe handling
NO contact with water or steam. NO contact with hot surfaces. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

SECTION 10: Stability and reactivity
Reactivity
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.
Chemical stability
Trialkylboranes are stable indefinitely when stored under an inert atmosphere. Trialkylboranes
Possibility of hazardous reactions
Not flammableThe vapour is heavier than air.BORON TRIBROMIDE strongly attacks wood and rubber with generation of flammable hydrogen gas. Reacts exothermically and violently with water. Mixing tungsten trioxide and boron tribromide caused an explosion when the reaction was not cooled in an ice bath.
Conditions to avoid
no data available
Incompatible materials
Reacts with water and various metals.
Hazardous decomposition products
On decomposition, /one mole of/ boron tribromide would be expected to produce three moles of hydrogen bromide.

Other Information
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.
