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

Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

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

Rinse mouth. Do NOT induce vomiting. 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.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

General First Aid:

(General first aid procedures)

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

2.0 [ppm]

Use water spray, dry chemical, "alcohol resistant" foam, or carbon dioxide. Use water spray to keep fire-exposed containers cool. Approach fire from upwind to avoid hazardous vapors and toxic decomposition products.

Do not use a solid stream of water because the stream will scatter and spread the fire. ... Fire fighters should wear self-contained breathing apparatus and full set of protective clothing.

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. Apply water from as far a distance as possible. Use "alcohol" foam, dry chemical or carbon dioxide.

Fire Fighting: Use self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive pressure mode.

Store in closed containers in a cool, dry, well-ventilated area.

Outside or detached storage is preferred. Separate from oxidizing materials, acids, and sources of halogens. Store in a cool, dry, well-ventilated location.

Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Establish forced ventilation to keep levels below explosive limit. Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or a similar material and deposit in sealed containers. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable. /Butyl Amines/

Evacuate danger area! Consult an expert! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. Personal protection: chemical protection suit including self-contained breathing apparatus.

1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quantities, absorb on paper towels. Evaporate in a safe place (such as fume hood). Allow sufficient time for evaporating vapors to completely clear the hood ductwork. ... butylamine should not be allowed to enter a confined space, such as sewer, because of the possibility of an explosion. Sewers designed to preclude the formation of explosive concentrations of butylamine vapors are permitted.

Environmental considerations-land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. Apply appropriate foam to diminish vapor and fire hazard. Neutralize with sodium bisulfate (NaHSO4).

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.

Incineration; incinerator is equipped with a scrubber or thermal unit to reduce NOx emissions. Alternatively it may be poured into sodium bisulfate, neutralized and flushed with water.

/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.

TERRESTRIAL FATE: Based on a classification scheme(1), Koc values ranging from 15 to 107(2) indicate that n-butylamine is expected to have high mobility in soil(SRC). The pKa of n-butylamine is 10.78(3) indicating that this compound will exist almost entirely in the cation form in the environment and therefore volatilization from moist soil surfaces is not expected to be an important fate process(SRC). The potential for volatilization of n-butylamine from dry soil surfaces may exist(SRC) based upon a vapor pressure of 92.9 mm Hg(4). Numerous screening studies indicate that n-butylamine will biodegrade readily(5-8); n-butylamine reached 67% of its theoretical BOD in 12 days using an activated sludge inoculum(5).

AQUATIC FATE: Based on a classification scheme(1), a Koc value range of 15 to 107 in soil and sediment(2), indicates that n-butylamine is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 10.78(3) indicates n-butylamine 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(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Numerous screening studies indicate that n-butylamine will biodegrade readily(8-11); n-butylamine reached 67% of its theoretical BOD in 12 days using an activated sludge inoculum(8).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-butylamine, which has a vapor pressure of 92.9 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-butylamine 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 11 hours(SRC) from its estimated rate constant of 3.4X10-11 cu cm/molecule-sec at 25 °C(3).

... The presence of volatile aliphatic amines ... in human breast milk and amniotic fluid /was measured/ to assess their role in neonatal hypergastrinemia. These volatile nitrogenous amino acid metabolites have been previously demonstrated to stimulate gastrin release in in vivo and in vitro laboratory preparations. ... The present study ... demonstrated that these gastrin-stimulatory volatile amines were present in significant concentrations in breast milk during the first several weeks after parturition and in amniotic fluid. The individual amines that were identified in both human milk and amniotic fluid samples were methylamine, dimethylamine, ethylamine, trimethylamine, propylamine, isobutylamine, and butylamine. This study provides indirect evidence to support the possibility that the hypergastrinemia measured in the fetus/neonate during the period immediately before and after birth may be attributable, in part, to the ingestion of fluid containing high concentrations of gastrin-stimulating amines.

/AQUATIC SPECIES/ Of 78 binary mixtures of equitoxic concns of 13 amines, the ethyl amine-aniline mixture (I-II) showed the greatest (32-fold) toxicity potentiation in a /freshwater algae/ Scenedesmus subspicatus reproduction test. ... Combining I with Butylamine ... potentiated the toxicity 8-fold.
