Most important symptoms/effects, acute and delayed
Highly toxic; may cause death or permanent injury after very short exposure to small quantities. Substance is irritating to the eyes, the skin, and the respiratory tract. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
If strong concentrations of boron trifluoride gas get into the eyes, wash eyes immediately with large amounts of water, lifting the lower and upper lids occasionally. Get medical attention immediately. Contact lenses should not be worn when working with this chemical.
SECTION 5: Firefighting measures
Suitable extinguishing media
Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Use water spray to keep fire-exposed containers cool. Extinguish fire using agent suitable for surrounding fire.
Specific hazards arising from the chemical
When heated to decomposition or upon contact with water or steam, it will produce toxic and corrosive fumes of fluorine containing compounds. Decomposes upon heating or on contact with moist air, forming toxic and corrosive fumes of boric acid and hydrofluoric acid. Reacts with alkalis and fumes in moist air, producing particulates which reduce visibility. Reacts with alkali metals, alkaline earth metals (except magnesium), alkyl nitrates, and calcium oxide. It hydrolyzes in moist air to form boric acid, hydrofluoric acid, and fluoboric acid. (EPA, 1998)
Special protective actions for fire-fighters
In case of fire in the surroundings: use appropriate extinguishing media. In case of fire: keep cylinder 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: complete protective clothing including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. Remove fumes with fine water spray.
Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. Remove fumes with fine water spray.
Methods and materials for containment and cleaning up
Approach release from upwind. Stop or control the leak, if this can be done without undue risk. Use water spray to cool and disperse vapors and protect personnel. Avoid wetting leak or spill area. Releases may require isolation or evacuation.
SECTION 7: Handling and storage
Precautions for safe handling
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.
Conditions for safe storage, including any incompatibilities
Separated from alkali metals, alkaline earth metals, alkyl nitrates and lime. Cool.Store in cool, dry, well-ventilated location. Outside or detached storage is preferred. Separate from water, active metals, monomers.

Other Information
Boron trifluoride is soluble in cold water, 332 g/100 ml at 0°C.The occupational exposure limit value should not be exceeded during any part of the working exposure.Depending on the degree of exposure, periodic medical examination is suggested.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.
