Definition of annotate in engineering11/6/2023 Cal/OSHA PELs are promulgated under statutory requirements for risk and feasibility that are no less protective than the OSH Act. California Division of Occupational Safety and Health (Cal/OSHA) Permissible Exposure Limits (PELs).Ĭal/OSHA has established an extensive list of PELs ( Cal/OSHA AC-1 Table) that are enforced in workplaces under its jurisdiction.However, OSHA recommends that employers consider using the alternative occupational exposure limits because the Agency believes that exposures above some of these alternative occupational exposure limits may be hazardous to workers, even when the exposure levels are in compliance with the relevant PELs. OSHA's mandatory PELs in the Z-Tables remain in effect. The tables list air concentration limits, but do not include notations for skin absorption or sensitization. OSHA has chosen to present a side-by-side table with the Cal/OSHA PELs, the NIOSH Recommended Exposure Limits (RELs) and the ACGIH ® TLVs ®s. To provide employers, workers, and other interested parties with a list of alternate occupational exposure limits that may serve to better protect workers, OSHA has annotated the existing Z-Tables with other selected occupational exposure limits. OSHA's Hazard Communication standard (1910.1200 Appendix D) requires that safety data sheets list not only the relevant OSHA PEL but also the ACGIH ® TLV ® and any other exposure limit used or recommended by the chemical manufacturer, importer, or employer preparing the safety data sheet. Many large industrial organizations have felt obligated to supplement the existing OSHA PELs with their own internal corporate guidelines. This has been demonstrated by the reduction in allowable exposure limits recommended by many technical, professional, industrial, and government organizations, both inside and outside the United States. Industrial experience, new developments in technology, and scientific data clearly indicate that in many instances these adopted limits are not sufficiently protective of worker health. Since 1970, OSHA promulgated complete 6(b) standards including new PELs for 16 agents, and standards without PELs for 13 carcinogens. Comparable PELs were adopted for shipyards (.1000) and construction (.55). Some consensus standards from the American Standards Association were also adopted at that time, following the 6(a) procedures. These in turn had been adopted from the 1968 Threshold Limit Values (TLVs ®) of the American Conference of Governmental Industrial Hygienists (ACGIH ®). 1000 were adopted from the Walsh-Healy Public Contracts Act as existing Federal standards for general industry. Most of the PELs contained in the Z-Tables of. Section 6(a) of the OSH Act granted the Agency the authority to adopt existing Federal standards or national consensus standards as enforceable OSHA standards. Most of OSHA's PELs were issued shortly after adoption of the Occupational Safety and Health (OSH) Act in 1970, and have not been updated since that time. OSHA recognizes that many of its permissible exposure limits (PELs) are outdated and inadequate for ensuring protection of worker health.
