Notes:
 

See 29 CFR 1910.1000 Table Z-1. OSHA Construction and Maritime PEL: A3 Gasoline and/or Petroleum Distillates. The composition of these materials varies greatly, and thus, a single TLV for all types of these materials is no longer applicable. The content of benzene, other aromatics, and additives should be determined in order to arrive at the appropriate TLV (ACGIH, 1970). See 29 CFR 1926.55 Appendix A, §1926.6(g)(1) Incorporation by reference; 29 CFR 1915.1000 Table Z- Shipyards, §1915.5(d)(3)(i) Incorporation by reference.
