Carbon tetrachloride

IDLH Documentation

CAS number: 56­23­5

NIOSH REL: 2 ppm (12.6 mg/m³) 60­minute STEL; NIOSH considers carbon tetrachloride to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR 1990].

Current OSHA PEL: 10 ppm TWA, 25 ppm CEILING,

200 ppm 5­min MAXIMUM PEAK in any 4 hours

1989 OSHA PEL: 2 ppm (12.6 mg/m³) TWA

1993­1994 ACGIH TLV: 5 ppm (31 mg/m³) TWA, 10 ppm (63 mg/m³) STEL [skin], A3

Description of Substance: Colorless liquid with a characteristic ether­like odor.

LEL: . . Noncombustible Liquid

Original (SCP) IDLH: 300 ppm

Basis for original (SCP) IDLH: ACGIH [1971] reported that a severe case of human poisoning has been observed after a 3­hour exposure to concentrations ranging from 75 to 600 ppm and averaging about 210 ppm [Barnes and Jones 1967]. AIHA [1961] reported that exposures for 0.5 to 1 hour to 1,000 to 2,000 ppm have caused human fatalities from acute kidney damage [Fassett]. Kirk­Othmer [1964] reported that a 30­minute exposure to about 300 ppm causes symptoms of intoxication. Based on these data, an IDLH of 300 ppm is chosen.

Short­term exposure guidelines: None developed

ACUTE TOXICITY DATA

Lethal concentration data:

*Note: Conversion factor (CF) was determined with "n" = 2.8 [ten Berge et al. 1986].

Other human data: A severe case of poisoning was observed after a 3­hour exposure to concentrations ranging from 75 to 600 ppm and averaging about 210 ppm [Barnes and Jones 1967]. It has been reported that exposures to 1,000 to 2,000 ppm for 0.5 to 1 hour have caused human fatalities from acute kidney damage [AIHA 1961]. It has also been reported that a 30­minute exposure to about 300 ppm causes symptoms of intoxication [Kirk-Othmer 1964].
