4.2 Most important symptoms/effects, acute and delayed

It is classified as moderately toxic. Probable oral lethal dose for humans is 0.5 to 5 g/kg (between 1 ounce and 1 pint) for a 150 lb. person. The mean lethal dose is probably near 1 fluid ounce (44 g). It is a human suspected carcinogen. Also, it is a central nervous system depressant and a gastrointestinal irritant. It has caused rapid death attributable to cardiac arrest and delayed death from liver and kidney damage. (EPA, 1998)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Halogenated aliphatic hydrocarbons and related compounds/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Use water spray to keep fire-exposed containers cool. Extinguish fire using agent suitable for surrounding fire.

5.2 Specific hazards arising from the chemical

Container may explode in the heat of fire. When heated it liberates phosgene, hydrogen chloride, chlorine and toxic and corrosive oxides of carbon and chlorine. Chloroform explodes when in contact with aluminum powder or magnesium powder or with alkali metals (e.g., lithium, sodium, and potassium) and dinitrogen tetroxide. It reacts vigorously with acetone in the presence of potassium hydroxide or calcium hydroxide. It is oxidized by strong oxidizers such as chromic acid forming phosgene and chlorine. It reacts vigorously with triisopropylphosphine. It develops acidity from prolonged exposure to air and light. (EPA, 1998)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Decomposes at ordinary temp in sunlight in the absence of air, and in the dark in the presence of air.

10.3 Possibility of hazardous reactions

Not combustible.The vapour is heavier than air.A mixture of acetone and CHLOROFORM in a residue bottle exploded. Since addition of acetone to chloroform in the presence of base will result in a highly exothermic reaction, it is thought that a base was in the bottle. [MCA Case History 1661(1970)]. Powdered aluminum and carbon tetrachloride (also methyl chloride and chloroform or mixtures of these chemicals) exploded when heated (to 153° C) and by impact, [Chem. Eng. News 32:258(1954); UL Bull. Research 34 (1945), ASESB Pot. Incid. 39(1968)]. An inadequately cooled addition of sodium to a chloroform-methanol mixture (sodium methoxide) caused a violent explosion, [MCA Case History No. 693]. It is incompatible with dinitrogen tetraoxide, fluorine, sodium metal and alcohols, nitromethane, and triisopropylphosphine.

EPA: Probable human carcinogen. IARC: Possibly carcinogenic to humans. NTP: Reasonably anticipated to be a human carcinogen

Reproductive toxicity

Little information is available on the reproductive or developmental effects of chloroform in humans, via any route of exposure. A possible association between certain birth outcomes (e.g., low birth weight, cleft palate) and consumption of contaminated drinking water was reported. However, because multiple contaminants were present, the role of chloroform is unclear. Animal studies have demonstrated developmental effects, such as decreased fetal body weight, fetal resorptions, and malformations in the offspring of animals exposed to chloroform via inhalation. Reproductive effects, such as decreased conception rates, decreased ability to maintain pregnancy, and an increase in the percentage of abnormal sperm were observed in animals exposed to chloroform through inhalation. Animal studies have noted decreased fetal weight, increased fetal resorptions, but no evidence of birth defects, in animals orally exposed to chloroform.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Danio rerio (Zebra danio); Conditions: freshwater, flow through, 23°C, pH 8.15; Concentration: 121000 ug/L for 48 hr
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea); Conditions: freshwater, renewal, 25°C, pH >7; Concentration: 79000 ug/L for 24 hr; Effect: behavior, equilibrium
  • Toxicity to algae: EC50; Species: Scenedesmus subspicatus (Green algae, log growth phase); Conditions: freshwater, static, 24°C, pH 8.0-9.3; Concentration: 560000 ug/L for 48 hr; Effect: decreased population biomass
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

Chloroform was reduced from 0.12 mg/L to <40 ug/L after anaerobic digestion at 25°C for 53 days and then was digested aerobically for 20 days which reduced chloroform to a not detected level(1). Chloroform was not degraded aerobically or anaerobically in an aquifer storage and recovery site(2).

12.3 Bioaccumulative potential

The BCF values for chloroform range from 2.9-10.35(1). A log bioconcentration factor <1 for 4 species of fish have been reported(2,3). An experimental log BCF of 0.78 was also reported for chloroform(4). According to a classification scheme(5), these BCF values suggest the potential for bioconcentration in aquatic organisms is low.

12.4 Mobility in soil

A soil sorption study was conducted on chloroform in three distinctly different soils(1). Soils used were from Missouri (composed of 11.4% sand, 52.7% silt, 33.4% clay, 2.4% organic matter, at pH 6.9), California (composed of 45.1% sand, 35.2% silt, 21.7% clay, organic matter 1.7%, at pH 8.1), and Florida (composed of 91.7% sand, 6.3% silt, 2.0% clay, 1.6% organic matter, at pH 4.7)(1). The ratio of the amount of contaminant adsorbed in micrograms per gram of soil to the equilibrium concn in ppm was used to calculate a Kd value of 2.133 in the Missouri soil, 1.941 in the California soil, and 1.763 in the Florida soil(1). These values correspond to a Koc value ranging from 153-196 based upon the relationship between Kd and Koc(2). Chloroform is adsorbed most strongly to peat moss, less strongly to clay, very slightly to dolomite limestone and not at all to sand(3). The Koc values measured for 2 soils was 34; 3 other soils with the lowest organic carbon content in the same study gave no appreciable adsorption(4). Field experiments in which chloroform was injected into an aquifer and the concn in a series of observation wells determined, demonstrated that chloroform is very poorly retained by aquifer material (retardation factor 2-4), less so than other C1- and C2-halogenated compounds studied(4-5). Laboratory percolation studies with a sandy soil gave similar results (retardation factor <1.5)(6). Chloroform was reported to have a Koc of 65(7), 55(8), 47(9) and 34(10). According to a classification scheme(11), these Koc values suggest that chloroform is expected to have very high to moderate mobility in soil.

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods


The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging
