† indicates that exposure to the analyte is subject to an OSHA PEL (e.g., Table Z-1) or other OSHA regulatory limit. ‡ indicates that exposure to the analyte is regulated under an OSHA expanded standard.

Search results are gathered from both the chemical name as well as synonyms commonly used.

OSHA Standards and Exposure Limits

Employers must comply with a number of standards where employees are potentially exposed to chemical hazards. These include OSHA's Permissible Exposure Limits PELs for about 400 substances, which can be found as follows:

General Industry: 29 CFR 1910.1000, Toxic and Hazardous Substances Air contaminants and Z1, Z2, Z3 tables 29 CFR 1910.1001 - 29 CFR 1910.1018 29 CFR 1910.1025- 29 CFR 1910.1053

Construction: 29 CFR 1926.1101, Toxic and Hazardous Substances 29 CFR 1926.1101 – 29 CFR 1926.1153

Maritime: 29 CFR 1915.1000, Toxic and Hazardous Substances Substance-specific standards



OSHA's PELs are included in the "Exposure Limits" table for individual chemicals in the database. In addition, OSHA has separate substance-specific standards, which can be found in the "Notes" section of the "Exposure Limits" table.

Other OSHA standards that generally apply to hazardous substances include the Hazard Communication standard (1910.1200) and the Respiratory Protection standard (1910.134). Employers may also need to provide personal protective clothing (1910.132) where there is a potential hazard from skin contact with chemicals, or eye and face protection to guard against chemical splashes (1910.133).
