This review identified specific substances from a larger group of 115 for which data existed indicating that the current OSHA standards may not be sufficiently protective. The rulemaking process by OSHA for these 115 had for various reasons been suspended. In a preliminary analysis to OSHA in October of 1983, NIOSH recommended that the rulemaking process proceed for 36 of the substances with previously published NIOSH criteria documents in which recommendations were made to reduce the exposure limits currently enforced as OSHA permissible exposure limits. The evaluation of the total list of 115 has been completed. A summary of available information was provided for each of the substances, including production, major uses, existing standards, toxicology, work related health problems, NIOSH activities, and current recommendations to OSHA. An additional 15 substances has been identified in addition to the earlier 36 for which OSHA should proceed with rulemaking. The remaining 64 substances were grouped as follows: 18 for which rulemaking should be deferred, pending the outcome of studies now underway, and 46 for which insufficient information was available on which to base a new or revised OSHA standard.
