· 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.

General First Aid:

ALCOHOL 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 streams 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.

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.

/Absorb small spills with paper and/ burn the paper in a suitable location away from combustible materials. Large quantities can be reclaimed or collected & atomized in suitable combustion chamber equipped with appropriate effluent gas cleaning device.

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.

If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away.Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.

Personnel protection: Avoid breathing vapors. Keep upwind. ... Do not handle broken packages unless wearing appropriate personal protective equipment. If contact with the material anticipated, wear appropriate chemical protective clothing.

Excerpt from ERG Guide 132 [Flammable Liquids - Corrosive]:

SRP: When working with strong solutions of acids or bases or other caustic or corrosive materials, always wear a full face mask. When working with caustic or corrosive gases or vapors, a full face mask will not protect the eyes or prevent inhaling the material. A full face respirator is required.

Personnel protection: ... Wear appropriate chemical protective gloves, boots and goggles.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a log Kow of 1.33(2) and a regression-derived equation(3), indicates that butylmethylamine is expected to have high mobility in soil(SRC). The pKa of butylmethylamine is 10.9(4) indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of butylmethylamine from moist soil surfaces is not expected to be an important fate process given its cationic state(SRC). Butylmethylamine is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 50 mm Hg(SRC), determined from a fragment constant method(6).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a log Kow of 1.33(2) and a regression-derived equation(3), indicates that butylmethylamine is expected to adsorb to suspended solids and sediment(SRC). A pKa of 10.9(4) indicates butylmethylamine will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 2(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), butylmethylamine, which has an estimated vapor pressure of 50 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase butylmethylamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 5 hours(SRC), calculated from its rate constant of 7.8X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Butylmethylamine does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

The Koc of butylmethylamine is estimated as 130(SRC), using a log Kow of 1.33(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that butylmethylamine is expected to have high mobility in soil. The pKa of butylmethylamine is 10.9(4) indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

... amines from decomposing fish ... /Amines/

Aliphatic amines, including butylmethylamine were identified, not quantified, in tobacco leaves(1).

/OTHER TOXICITY INFORMATION/ Since the amines are bases and may form strongly alkaline solutions, they can be damaging if splashed in the eye or if allowed to contaminate the skin. Otherwise they have no specific toxic properties, and the lower aliphatic amines are normal constituents of body tissues, so that they occur in a large number of foods, particularly fish, to which they impart a characteristic odor. One area of concern at present is the possibility that some aliphatic amines may react with nitrate or nitrite in vivo to form nitroso compounds, many of which are known to be potent carcinogens in animals ... . /Aliphatic amines/

An estimated BCF of 2 was calculated in fish for butylmethylamine(SRC), using a log Kow of 1.33(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

A pKa of 10.9(1) indicates butylmethylamine will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces and moist soil surfaces is not expected to be an important fate process(2).
