붕소 트리염화물

It is not flammable. Use dry chemical, carbon dioxide, or dry sand to extinguish. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to absorb vapors. For large fires use water spray, fog, or foam. Do not get water on material itself. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Do not get water inside container. Move container from fire area if you can do so without risk. Stay away from ends of tanks. Spray cooling water on containers that are exposed to flames until well after fire is out. Isolate area until gas has dispersed. (EPA, 1998)

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.

Fresh 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.

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Do not touch or walk through spilled material.

Warning: Boron trichloride is extremely corrosive. Caution is advised.

General First Aid:

· Wear positive pressure self-contained breathing apparatus (SCBA).

TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].

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.

In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water.

Fireproof if in building. Separated from food and feedstuffs.

Storage temp: Ambient

Evacuate danger area! Consult an expert! Ventilation. (Extra personal protection: gas-tight chemical protection suit including self-contained breathing apparatus).

Neutralize spilled material with crushed limestone, soda ash, or lime.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity 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 and plant life; and conformance with environmental and public health regulations.

Attach an appropriate control valve provided with a trap or check valve and a long piece of flexible hose connected to the control valve outlet. Discharge the gas at a moderate rate into an adequate amount of about 15% aqueous sodium hydroxide or other alkali in a suitable container. When the gas has been discharged, close the valve and transport to neutralization plant for disposal.

Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed.

Pain. Redness. Blisters. Skin burns. ON CONTACT WITH LIQUID: FROSTBITE.

Pain. Redness. Severe deep burns. Loss of vision.

/SIGNS AND SYMPTOMS/ Inhalation of boron trichloride vapor results in edema and irritation of upper respiratory tract.

/SIGNS AND SYMPTOMS/ Classified as a corrosive liquid to the skin and mucous surfaces due to its rapid hydrolysis to hydrochloric acid (and boric acid) by moisture.

/SIGNS AND SYMPTOMS/ EFFECTS OF SHORT-TERM EXPOSURE: ...Inhalation of the gas may cause lung edema. Rapid evaporation of the liquid may cause frostbite. Exposure at high levels may result in death. The effects may be delayed. Medical observation is indicated.

/SIGNS AND SYMPTOMS/ /Effects on exposure by/ inhalation /may include/ sore throat, cough, burning sensation, shortness of breath, and labored breathing.

According to the 2006 TSCA Inventory Update Reporting data, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of boron trichloride is 1 to 99; the data may be greatly underestimated(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 1,125 workers (613 of these are female) are potentially exposed to boron trichloride(1). Occupational exposure to boron trichloride may occur through inhalation and dermal contact with this compound at workplaces where boron trichloride is produced or used(SRC).

Industrial exposures ... occur from release ... into the worker atmosphere as well as from production & handling ... /Boron halides/

The chemistry of boron is dominated by its tendency to form stable bonds with electronegative atoms, especially oxygen. Reduced boron compounds (halides, hydrides, alkyls and aryls) tend to oxidize and hydrolyze readily, and would be expected to be converted into various boron-oxide compounds in the environment. Inorganic boron compounds are nonvolatile and would not be expected to volatilize from moist or dry soil surfaces. (SRC)

ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.

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/

If renal failure occurs, hemodialysis may be necessary to maintain fluid balance and normal extracellular fluid composition. Hemodialysis has had limited success in enhancing clearance of borates. Peritoneal dialysis has been performed in borate poisoning and is felt to be as effective as, and safer than, exchange transfusion in removing borate. No large study has been done, but it is still used somewhat less frequently than hemodialysis. /Boric acid and Borates/
