-CLINICAL EFFECTS
GENERAL CLINICAL EFFECTS
- Direct skin contact may cause burns. Direct eye contact may cause corneal burns.
- Boron trifluoride itself can cause severe respiratory tract irritation with chemical pneumonitis and possible pulmonary edema.
- Ethers have anesthetic properties and can cause CNS depression, coma, and respiratory depression.
- This material could release toxic and irritating fluoride and fluoroboride compounds on thermal decomposition.
- POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)
Highly toxic: contact with water produces toxic gas, may be fatal if inhaled. Inhalation or contact with vapors, substance, or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
-FIRST AID
FIRST AID AND PREHOSPITAL TREATMENT
FLUORIDE BINDING - Attempt immediate administration of a fluoride binding substance. Options include milk (one-half to one glassful), chewable calcium carbonate tablets, or milk of magnesia. Avoid large amounts of liquid, since this may induce vomiting.
-MEDICAL TREATMENT
LIFE SUPPORT
- Support respiratory and cardiovascular function.
SUMMARY
- FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, wipe from skin immediately; flush skin or eyes with running water for at least 20 minutes. Keep victim warm and quiet. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
EYE EXPOSURE - Irrigate promptly with crystalloid solution (lactated ringer's or normal saline) for at least 30 minutes. Carefully evaluate for eye damage. The patient should be evaluated by an ophthalmologist following appropriate decontamination. DERMAL EXPOSURE - Prompt decontamination of the affected area is of primary importance. Specific treatment is controversial, with no single type of therapy clearly superior. Topical calcium gluconate gel or magnesium oxide paste has been successful. Local calcium gluconate infiltration may be considered in some cases. Significant systemic absorption from dermal exposure may cause symptomatic hypocalcemia, hyperkalemia, and hypomagnesemia which will require aggressive treatment. ORAL EXPOSURE - Do NOT induce vomiting. Administer fluoride-binding substance (options include milk, chewable calcium carbonate tablets, milk of magnesia). Consider nasogastric or soft orogastric suction and lavage with 10% calcium gluconate if large and recent ingestion, and spontaneous emesis has not occurred. Monitor and treat hypocalcemia, hypomagnesemia, hyperkalemia parenterally as needed. INHALATION EXPOSURE - Move the patient to fresh air and administer 100% humidified supplemental oxygen with assisted ventilation as required. Monitor for respiratory signs and symptoms and treat symptomatically. Nebulized calcium gluconate has been used in the treatment of HF inhalation exposure. However, its clinical efficacy is uncertain (NIOSH , 1998).

-PERSONAL PROTECTION
SUMMARY
- RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)
Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.
RESPIRATORY PROTECTION
- Refer to "Recommendations for respirator selection" in the NIOSH Pocket Guide to Chemical Hazards on TOMES Plus(R) for respirator information.
-PHYSICAL HAZARDS
FIRE HAZARD
POTENTIAL FIRE OR EXPLOSION HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004) Produce flammable and toxic gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Containers may explode when heated. Runoff may create fire or explosion hazard.
Boron trifluoride methyl ether is a flammable liquid (IATA, 1991; (Lewis, 1992).
- FIRE CONTROL/EXTINGUISHING AGENTS
FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004) SMALL FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004) LARGE FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004) DRY sand, dry chemical, soda ash or lime or withdraw from area and let fire burn. FOR CHLOROSILANES, DO NOT USE WATER; use AFFF alcohol-resistant medium expansion foam; DO NOT USE dry chemicals, soda ash or lime on chlorosilane fires (large or small) as they may release large quantities of hydrogen gas that may explode. Move containers from fire area if you can do it without risk.
TANK OR CAR/TRAILER LOAD FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004) Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not get water inside containers. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire.
Boron trifluoride methyl ether can evolve toxic and irritating fumes of fluorides and fluoroborides when hydrolyzed or heated to decomposition; hydrofluoric acid, fluoboric acid, and hydrochloric acid are released in a fire involving this compound (HSDB , 1993; Lewis, 1992).
EXPLOSION HAZARD
- Boron trifluoride methyl ether is a peroxide containing ether that reacts explosively with solid lithium tetrahydroaluminate (Lewis, 1992).
- It is also incompatible with water, steam, and oxidizing materials, a violent explosion may result (Lewis, 1992).
- Interaction of hexafluorisopropylideneaminolithium with a range of chloro- and fluoro- derivatives of BORON during warming to 25 degrees C tended to be violently exothermic in the absence of solvent (HSBD, 1993).
DUST/VAPOR HAZARD
- Boron trifluoride methyl ether dust or water-reactant by-products are corrosive (Lewis, 1992).
- It can evolve toxic and irritating fumes of fluorides and fluoroborides when hydrolyzed or heated to decomposition (EPA, 1985; ACGIH, 1986).
REACTIVITY HAZARD
- Boron trifluoride methyl ether is corrosive (Lewis, 1992).
- This compound can evolve toxic and irritating fumes of fluorides and fluoroborides when hydrolyzed or heated to decomposition (EPA, 1985; ACGIH, 1986).
- It is a peroxide containing ether that reacts explosively with solid lithium tetrahydroaluminate (Lewis, 1992).
- It is also incompatible with water, steam, and oxidizing materials (Lewis, 1992).
- Boron trihalides are reduced by active metals, metal hydrides, and hydrogen. Elemental boron and the metal halide will be produced at elevated temperatures in the presence of an alkali and alkali earth metals (HSDB , 1993).
- The trihalides react with water, lower alcohols, hydrogen sulfide, alkyl mercaptans, ammonia, primary and secondary amines, phosphine and arsine (HSDB , 1993).
- The following information is for BORON HALIDES (HSDB , 1993):
Interaction of hexafluorisopropylideneaminolithium with a range of chloro- and fluoro- derivatives of boron during warming to 25 degrees C tended to be violently exothermic in the absence of solvent. Boron trihalides react with water, lower alcohols, hydrogen sulfide, alkyl mercaptans, ammonia, primary and secondary amines, phosphine, and arsine, liberating hydrogen halide in each case. Boron halides react violently with water, and particularly if there is a deficiency of water, a violent explosion may result. Boron halides are reduced by active metals, metal hydrides, and hydrogen. Reaction with the alkali and alkaline earth metals at elevated temperature yields elemental boron and the metal halide.
