The Tennessee Department of Labor and Workforce Development/Division of Occupational Safety and Health (TOSHA) administers and enforces workplace safety and health rules for private and public sector workplaces in the state.
PELS Rule 0800-1-1-.07
The state air contaminants standards for general industry contain PELs for several dozen chemicals for which federal OSHA does not have a PEL, and lower PELs for certain carcinogens. See the PEL table for exposure limits on specific chemicals.
Federal OSHA had revised its Z tables of hazardous substances and PELs in the 1980s to include the substances adopted by Tennessee's standards, but in 1992 a federal circuit court struck down the OSHA revisions. Several states, including California, Michigan, Oregon, Tennessee, and Washington, retained some of the PELs from the pre 1989 OSHA Z tables which are stricter than existing federal standards.
