붕산트리메틸

Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]:

Use foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

Fresh air, rest.

Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. 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.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]:

General First Aid:

To fight fire use dry chemical, CO2, spray, foam.

If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid stream of water may be ineffective. Cool all affected containers with flooding quantities of water. Use "alcohol" foam, dry chemical or carbon dioxide. Keep run-off water out of sewers and water sources.

Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: self-contained breathing apparatus). /table/

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.

Personal protection: filter respirator for organic vapours of low boiling point adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Do NOT wash away into sewer. Absorb remaining liquid in dry sand or inert absorbent. Then store and dispose of according to local regulations.

Do not breathe gas, fumes, vapor, or spray. Avoid contact with eyes.

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.

SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

TERRESTRIAL FATE: Trimethyl borate is rapidly hydrolyzed to boric acid and methanol in the presence of water(1,2). Hydrolysis would be expected to be the dominate fate process for trimethyl borate in the environment(SRC).

AQUATIC FATE: Trimethyl borate is rapidly hydrolyzed to boric acid and methanol in the presence of water(1,2). Hydrolysis would be expected to be the dominate fate process for trimethyl borate in the environment(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), trimethyl borate, which has a vapor pressure of 136 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Trimethyl borate is rapidly hydrolyzed to boric acid and methanol in the presence of water(3,4). Hydrolysis would be expected to be the dominate fate process for trimethyl borate in the environment(SRC).

Cough. Sore throat.

Redness. Burning sensation.

Redness. Pain.

Burning sensation. Abdominal pain.

Trimethyl borate is rapidly hydrolyzed to boric acid and methanol in the presence of water(1,2). Hydrolysis would be expected to be the dominate fate process for trimethyl borate in the environment(SRC). Adsorption to soil or suspended particles in water is not considered an important environmental fate for trimethyl borate(SRC).

/SIGNS AND SYMPTOMS/ Inhalation: Cough, sore throat. Eyes: Redness, pain. Skin: Redness, burning sensation. /table/

/OTHER TOXICITY INFORMATION/ Harmful in contact with skin

Trimethyl borate's production and use as a solvent, flame retardant for textiles, dehydrating agent, brazing flux, wood preservative, catalyst, as well as it use as an intermediate for the synthesis of boron compounds and in scintillation counters(1-3) may result in its release to the environment through various waste streams(SRC). Trimethyl borate is used to treat wood where it is decomposed to boric acid upon contact with the moisture in the wood; the boric acid formed acts as a wood preservative preventing damage from wood-destroying fungi and insects(2).

Trimethyl borate is rapidly hydrolyzed to boric acid and methanol in the presence of water(1,2). Hydrolysis would be expected to be the dominate fate process for trimethyl borate in the environment(SRC). Bioconcentration is not considered an important environmental fate for trimethyl borate(SRC).

Trimethyl borate is rapidly hydrolyzed to boric acid and methanol in the presence of water(1,2). Hydrolysis would be expected to be the dominate fate process for trimethyl borate in the environment(SRC). Volatilization from water or soil is not considered an important environmental fate for trimethyl borate(SRC).
