Notes:

See 29 CFR 1910.1000 Table Z-2. The OSHA Construction and Maritime Industries PEL is 20 ppm (60 mg/m³) as an 8 hr TWA, but there are no Construction or Maritime Ceiling or Peak values for carbon disulfide. Construction and Maritime regulations include a skin designation. See 29 CFR 1926.55 Table 1 and 29 CFR 1915.1000 Table Z-Shipyards.
