Description of first aid measures
If inhaledFresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. 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 with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms and effects, both acute and delayed
Strong irritant to tissue. Fumes are corrosive and highly toxic. Boron affects the central nervous system causing depression of circulation as well as shock and coma. May cause severe burns to skin. May result in marked fluid and electrolyte loss and shock. (EPA, 1998)
Indication of any immediate medical attention and special treatment needed
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
Extinguishing media
If material involved in fire: Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Specific Hazards Arising from the Chemical
When heated to decomposition, it emits toxic fumes of chlorides. It will react with water or steam to produce heat, and toxic and corrosive fumes. In hot water, decomposes to hydrochloric acid and boric acid. Fumes and hydrolyzes in moist air to form hydrochloric acid and oily, irritating corrosives. Avoid aniline, hexafluorisopropylidene amino lithium, nitrogen dioxide, phosphine, grease, organic matter, and oxygen. Nitrogen peroxide, phosphine, fat or grease react energetically with boron trichloride. Oxygen and boron trichloride react vigorously on sparking. Boron trichloride and aniline react violently in the absence of a coolant or diluent. Stable. (EPA, 1998)
Advice for firefighters
NO water. 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.

Reactivity
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride. Reacts violently with water and moist air. This produces hydrogen chloride and boric acid. Reacts violently with aniline, phosphine, alcohols, oxygen and organic matter such as grease. Attacks many metals in the presence of water.
Chemical stability
Trialkylboranes are stable indefinitely when stored under an inert atmosphere. Trialkylboranes
Possibility of hazardous reactions
Not flammableThe gas is heavier than air.BORON TRICHLORIDE vigorously attacks elastomers and packing materials. Contact with Viton, Tygon, Saran and natural and synthetic rubbers is not recommended. Highly corrosive to most metals in the presence of moisture. Reacts energetically with nitrogen dioxide/dinitrogen tetraoxide, aniline, phosphine, triethylsilane, or fat and grease [Mellor 5:132 1946-47]. Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides).
