1,3-Dichlorpropan

Fire Extinguishing Agents: Foam, carbon dioxide, dry chemical. (USCG, 1999)

Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Fresh air, rest.

First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.

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.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Evacuate danger area! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer. Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.

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.

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.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 290(SRC), determined from a log Kow of 2.0(2) and a regression-derived equation(3), indicates that 1,3-dichloropropane is expected to have moderate mobility in soil(SRC). Volatilization of 1,3-dichloropropane from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 9.76X10-4 atm-cu m/mole(4). The potential for volatilization of 1,3-dichloropropane from dry soil surfaces may exist (SRC) based upon a vapor pressure of 18.2 mm Hg(5). Using a standard dilution method and a sewage seed inoculum, 1,3-dichloropropane achieved 16% of the theoretical BOD during a 5 day incubation period(6), suggesting biodegradation may occur in soil(SRC). The hydrolysis half-life of 1,3-dichloropropane is 2.3 years at pH 7 and 25 °C(7), suggesting hydrolysis will occur slowly in moist soils(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 290(SRC), determined from a log Kow of 2.0(2) and a regression-derived equation(3), indicates that 1,3-dichloropropane is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 9.76X10-4 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2 hours and 4.5 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 7(SRC) from its log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low. The hydrolysis half-life of 1,3-dichloropropane is 2.3 years at pH 7 and 25 °C(7). Using a standard dilution method and a sewage seed inoculum, 1,3-dichloropropane achieved 16% of the theoretical BOD during a 5 day incubation period(8), suggesting biodegradation may occur in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,3-dichloropropane, which has a vapor pressure of 18.2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,3-dichloropropane 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 21 days(SRC), calculated from its rate constant of 7.8X10-13 cu cm/molecule-sec at 25 °C(3).

The Koc of 1,3-dichloropropane is estimated as 290(SRC), using a measured log Kow of 2.0(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,3-dichloropropane is expected to have moderate mobility in soil.

Toxicity of 1,3-dichloropropane (DCP) with respect to testicular changes was evaluated in male albino Wistar rats (10/treated group, 20 in arachis oil vehicle control group) exposed orally to DCP by gavage at dosage levels of 0, 100 or 400 mg/kg/day for 14 days. On day 15, the animals were sent for pathological examination. No significant differences between treated and control animals were observed in the following: maternal mortality, clinical observations, body weights and weight gain, testes weights, morphology, or detailed macroscopic and microscopic examination of the kidneys, testes, epididymides, ductuli efferentes, and vasa deferentes.

The mutagenicity of 1,3-dichloropropane was evaluated in Salmonella tester strains TA1535, TA1537, TA1538, TA98 and TA100 (Ames Test), Escherichia coli test strains WP2 and WP2 uvrA and Saccharomyces cerevisiae strain JD1, both in the presence and absence of added metabolic activation by Aroclor-induced rat liver S9 fraction. Bacterial cultures were tested at concentrations up to 4000ug/plate using the plate incorporation technique. 1,3-Dichloropropane was tested at concentrations up to 5.0mg/ml in liquid suspension cultures of Saccharomyces cerevisiae. 1,3-Dichloropropane produced a dose-related increase in the reversion frequency in Salmonella tester strain TA1535 at concentrations at or above 500ug/plate in the presence of metabolic activation. 1,3-Dichloropropane did not cause a positive response in any of the remaining tester strains with or without metabolic activation.

The ability of 1,3-dichloropropane (DCP) to cause chromosome aberrations in cultures of rat liver (RL4) cells was evaluated in the absence of added metabolic activation. Monolayer slide cultures of RL4 cells were exposed to 0, 125, 250 or 500 ug/ml for 24 hrs and 100 cells/culture (200-300 cells/dose level) were scored for chromosome aberrations. None of the cultures produced frequencies of chromosome aberrations statistically greater than those produced by the controls (DMSO vehicle).
