Abstract: OSHA is amending its existing Air Contaminants standard, [1910. 1000] including Tables Z-1, Z-2, and Z3. This amendment is limited to making more protective 212 Permissible Exposure Limits (PEL) listed in these Tables; setting new PEL's for 164 substances not currently regulated by OSHA; and maintaining other PELs unchanged. Changes include revision of the PEL; inclusion of Short Term Exposure Limits (STEL) to complement 8 hour time weighted average (TWA) limits; establishment of skin designation; and addition of ceiling limits as appropriate. All of the revised PELs are included in a single new Table Z-1-A which also includes the existing OSHA PELs under the Transitional Limits Columns. This rule effective 3/1/89; start-up date with any combination of controls is 9/1/89; start-up date for compliance with preference for feasible engineering controls is 12/31/92 or in certain circumstances 12/31/93.
