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: 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 disperse vapors and dilute standing pools of liquid.

Personnel protection: Avoid breathing vapors. Keep upwind. Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. ... If contact with the material anticipated, wear appropriate chemical protective clothing.

/OTHER TOXICITY INFORMATION/ Vapor may injure eyes and respiratory tract ... .

/OTHER TOXICITY INFORMATION/ ... 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.

/LABORATORY ANIMALS: Acute Exposure/ ... Cause severe injury to rabbit eye and guinea pig skin. 5 of 5 rats died during exposure to 3200 ppm (calculated) ... but no deaths occurred after 1600 ppm for 8 hr. One of 10 rats died & others exhibited reduced growth during 50 7-hr exposures to 400 ppm. Weight loss, corneal opacities, & death occurred in all animals exposed repeatedly to 800 ppm.

/LABORATORY ANIMALS: Acute Exposure/ 1-Aminopropane, a strong irritant, volatile alkaline liquid has caused clouding of the cornea in rats during lethal exposure to 800 ppm in air. Test application to rabbit eyes caused severe injury, graded 9 on a scale of 1 to 10 after twenty-four hours.

/LABORATORY ANIMALS: Acute Exposure/ Sensory irritation due to inhalation of a series of alkylamines was estimated from the decrease in respiratory rate in normal (non-cannulated) mice (American standard method E 981-84, 1984). The irritation effects rapidly reached stable levels. The concentration-response relationships followed Michaëlis-Menten equations. The maximum response decreased with increasing chain length. The concentrations depressing the respiratory rate by 50% (RD-50) were 184, 121, 97, 51, and 27 p.p.m. for n-propylamine, n-butylamine, n-pentylamine, n-hexylamine, and n-heptylamine, respectively. It is suggested that the receptor is activated partly by the amines and partly by hydroxide ions. The nose has a scrubbing effect, which partly protects the lungs against water soluble irritants. Pulmonary irritation was estimated from the decrease in respiratory rate in tracheally cannulated mice. The plateau-level of the response was reached slowly. The respective concentrations depressing the respiratory rate by 50% (tRD-50) were 416, 300, 128, 66, and 36 p.p.m. for the C3-C7 n-amines

/OTHER TERRESTRIAL SPECIES/ ... This research compared the toxicity and inhibition caused by three aliphatic amines (n-propylamine, ethylmethylamine, and trimethylamine) and their chlorinated derivatives. ... Acute toxicity assays were conducted by using a Microtox system with Phosphobacterium phosphoreum (also known as Vibrio fischeri) for the aliphatic amine compounds and their corresponding chlorinated derivatives, as identified by membrane introduction mass spectrometry (MIMS). Inhibition tests were conducted by using the oxygen utilization rate test with an enhanced nitrifier culture. ... Trimethylamine and n-propylamine caused greater inhibition to nitrifiers than did ethylmethylamine under similar concentrations. Nitrifier inhibition from these amines increased after chlorination.

The substance is harmful to aquatic organisms.

Propylamine's production and use in dyestuffs, pharmaceuticals, agricultural chemicals, corrosion inhibitors, textile and leather finishing resins, and in manufacturing rubber chemicals may result in its release to the environment through various waste streams. Propylamine is found in various plants, such as tobacco and algae, as a volatile emission product from animal waste, and in various foods. If released to air, a vapor pressure of 310 mm Hg at 25 °C indicates propylamine will exist solely as a vapor in the atmosphere. Vapor-phase propylamine will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 12 hours. Propylamine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, propylamine is expected to have very high mobility based upon an estimated Koc of 43. The pKa of propylamine is 10.71, 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. Volatilization from moist soil surfaces is not expected to be an important fate process based upon its cationic state. propylamine may volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation is expected to be an important fate process in both soil and water, based upon propylamine's biodegradation in aqueous screening tests. If released into water, propylamine is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Biodegradation of propylamine is expected to be rapid; a BODT of 102% was measured using a sludge inoculum. A pKa of 10.71 indicates propylamine 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. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to propylamine may occur through inhalation and dermal contact with this compound at workplaces where propylamine is produced or used.

Propylamine has been reported in various species of marine algae(1) and in Latakia tobacco leaf(2). Propylamine can occur as a bio-organic degradant(3) and as a volatile emission product from animal waste(4). Propylamine has also been detected in various foods(5).

Propylamine's production and use in dyestuffs, pharmaceuticals, agricultural chemicals, corrosion inhibitors, textile and leather finishing resins, and in manufacturing rubber chemicals(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 43(SRC), determined from a log Kow of 0.48(2) and a regression-derived equation(3), indicates that propylamine is expected to have very high mobility in soil(SRC). The pKa of propylamine is 10.71(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 propylamine from moist soil surfaces is not expected to be an important fate process given its cationic state(SRC). Propylamine is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 310 mm Hg(6). Biodegradation of propylamine is expected to occur(7-9); a 102% theoretical BOD was measured after 13 days using a non-activated sludge inoculum(7).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 43(SRC), determined from a log Kow of 0.48(2) and a regression-derived equation(3), indicates that propylamine is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 10.71(4) indicates propylamine 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 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation of propylamine is expected to occur(8-10); a 102% of theoretical BOD was measured after 13 days using a non-activated sludge inoculum(8).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), propylamine, which has a vapor pressure of 310 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase propylamine 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 12 hours(SRC), calculated from its rate constant of 3.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Propylamine 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).

AEROBIC: Propylamine was readily bio-oxidized in Warburg respirometer studies using aniline-acclimated activated sludge(1). Using a non-activated sludge inoculum, 102% of the theoretical BOD was measured over a 13 day time period(2). Propylamine was readily acclimated to and metabolized by an activated sludge(3).

The rate constant for the vapor-phase reaction of propylamine with photochemically-produced hydroxyl radicals has been estimated as 3.3X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 12 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the aqueous-phase reaction with photochemically-produced hydroxyl radicals has been determined to be 6.6X10+9 L/mol-sec at pH 8-13(2). This corresponds to an aqueous half-life of approximately 122 days at an aqueous hydroxyl radical concn of 1.0X10-17 mol/L(2). Propylamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Propylamine does not contain chromophores that absorb at wavelengths >290 nm(3) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 3 was calculated in fish for propylamine(SRC), using a log Kow of 0.48(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).

The Koc of propylamine is estimated as 43(SRC), using a log Kow of 0.48(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that propylamine is expected to have very high mobility in soil. The pKa of propylamine is 10.71(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).

A pKa of 10.71(1) indicates propylamine 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). Propylamine is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 310 mm Hg(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.
