Do NOT use halogenated extinguishing agents.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

All equipment should be fully enclosed and carefully designed to eliminate any likelihood of autoignition. All equipment must be purged before opening. All possible sources of ignition should be eliminated and processes in which boron hydrides are heated must be minutely controlled. Automatic leak detectors with visual and acoustic warning signals should be fitted. Where possible, processes should be automated or operated by remote control. /Boron hydrides/

All containers should be thoroughly flushed before maintenance work is carried out on them and, in event of leakage, only persons with adequate personal protective equipment should be allowed in vicinity of containers. /Boranes/

Maintain an open airway and assist ventilation if nescessary. treat coma, seizures, hypotension, and renal failure if they occur. There is no specific antidote. Administer activated charcoal (although boric acid is not well absorbed). Consider gastric lavage for large ingestions. /Boric acid, Borates, and Boron/

Hemodialysis is effective and is indicated after massive ingestions and for supportive care of renal failure. Peritoneal dialysishas not proved effective in enhancing elimination in infants. /Boric acid, Borates, and Boron/

In acute poisonings, if a large amount has been ingested and the patient is seen within one hour of exposure, gastrointestinal decontamination should be considered ... .It is important to keep in mind that vomiting and diarrhea are common, and severe poisoning may be associated with seizures. Therefore induction of emesis by syrup of ipecac is probably contraindicated in these exposures. Catharsis is not indicated if diarrhea is present. /Boric acid and Borates/

If ingestion of borate has been massive (several grams), or has extended over several days, administer intravenous glucose and electrolyte solutions to sustain urinary excretion of borate. Monitor fluid balance and serum electrolytes (including bicarbonate capacity ) regularly. Monitor cardiac status by ECG. Test the urine for proteins and cells to detect renal injury, and monitor serum concentration of borate. Metabolic acidosis may be treated with sodium bicarbonate. If shock develops, it may be necessary to infuse plasma or whole blood. Administer oxygen continuously. If oliguria (less than 25 to 30 mL urine per hour) occurs, intravenous fluids must be slowed or stopped to avoid overloading the circulation. Such patients should be referred to a center capable of providing intensive care for critically ill patients. /Boric acid and Borates/

Triethylboron's production and use as an igniter or fuel for jet and rocket engines, fuel additive, olefin polymerization catalyst, and as a chemical intermediate may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 53 mm Hg at 25 °C indicates triethylboron will exist solely as a vapor in the ambient atmosphere. Triethylboron is spontaneously flammable in air and reacts with water. These rapid reactions should dominate over all other environmental fate processes, and triethylboron should have a very short existence in the environment. Occupational exposure to triethylboron may occur through inhalation and dermal contact with this compound at workplaces where triethylboron is produced or used. When used commercially, triethylboron would need to be handled in an inert atmosphere. The high reactivity, rapid decomposition, and commercial handling techniques suggest that triethylboron would decompose before occupational exposure can occur, should small amounts be released. Exposure to the general population is not be expected because of the spontaneous decomposition of triethylboron on contact with oxygen or moisture. (SRC)
