Notes:

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