10.3 Possibility of hazardous reactions

Not flammableThe vapour is heavier than air.CARBON TETRACHLORIDE is a commonly used liquid in fire extinguishers to combat small fires. It has no flash point, it is not flammable. However, when heated to decomposition, it will emit fumes of extremely toxic phosgene and of hydrogen chloride. Forms explosive mixtures with chlorine trifluoride, calcium hypochlorite, decaborane, dinitrogen tetraoxide, fluorine. Forms impact-sensitive explosive mixtures with particles of many metals: lithium, sodium, potassium, beryllium, zinc, aluminum, barium. Vigorous exothermic reaction with allyl alcohol, boron trifluoride, diborane, disilane, aluminum chloride, dibenzoyl peroxide, potassium tert-butoxide, liquid oxygen, zirconium. [Bretherick, 5th ed., 1995, p. 666]. Potentially dangerous reaction with dimethylformamide or dimethylacetamide in presence of iron [Cardillo, P. et al., Ann. Chim. (Rome), 1984, 74, p. 129].

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

11.Toxicological information

Acute toxicity

  • Oral: LD50 Rat oral 2920 mg/kg
  • Inhalation: no data available
  • Dermal: no data available

Skin corrosion/irritation

no data available

Serious eye damage/irritation

no data available

Respiratory or skin sensitization

no data available

Germ cell mutagenicity

no data available

Carcinogenicity

NTP: Reasonably anticipated to be a human carcinogen

Reproductive toxicity

No information is available on the reproductive effects of carbon tetrachloride in humans. Limited epidemiological data have indicated a possible association between certain birth outcomes (e.g., birth weight, cleft palate) and drinking water exposure. However, as the water contained multiple chemicals, the role of carbon tetrachloride is unclear. Decreased fertility and degenerative changes in the testes have been observed in animals exposed to carbon tetrachloride by inhalation. Birth defects have not been observed in animals exposed to carbon tetrachloride by inhalation or ingestion.

STOT-single exposure

no data available

STOT-repeated exposure

no data available

Aspiration hazard

no data available

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 Lepomis macrochirus (Bluegill) 125,000 ug/l/96 hr (static unmeasured)
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: The static screening flask test method measured >87% degradation of carbon tetrachloride in 7 days in the original test, and 100% degradation in the second, third, and fourth trials(1). In a standard dilution test, 0% Theoretical BOD for carbon tetrachloride was measured(2).

12.3 Bioaccumulative potential

A BCF of 3.2-7.4 for carbon tetrachloride was measured(1). A measured BCF value for trout, rainbow trout and bluegill sunfish was found to be 17.37(2,3), 52.48(5), and 30.2(4) and 26.3(5), respectively. According to a classification scheme(6), these BCF values suggest the potential for bioconcentration in aquatic organisms is low.

12.4 Mobility in soil

The Koc for carbon tetrachloride was measured to be 71(1). According to a classification scheme(4), this Koc value suggests that carbon tetrachloride is expected to have high mobility in soil. Estimated retardation factor in breakthrough sampling in groundwater - 1.44-1.8(2,3).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.
