SECTION 4: First-aid measures
4.1 Description of necessary first-aid measures
If inhaled
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Following skin contact
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Following ingestion
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.
4.2 Most important symptoms/effects, 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)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
SECTION 5: Fire-fighting measures
5.1 Suitable 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.
5.2 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)
5.3 Special protective actions for fire-fighters
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.
