The permissible exposure limit (PEL or OSHA PEL) is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent such as high level noise. Permissible exposure limits were established by the Occupational Safety and Health Administration (OSHA). Most of OSHA's PELs were issued shortly after adoption of ...
An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health .
National Institute for Occupational Safety and Health (NIOSH) RELs are designed to protect the health and well-being of workers by recommending safe exposure levels. To really use these guidelines well, safety professionals need to understand the recommended exposure levels, how to measure them, and ways to make sure workers aren't exposed to harmful stuff.
In 1970, the US Occupational Health and Safety Act was signed into law, [6] which created the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health.

OSHA sets enforceable permissible exposure limits (PELs) to protect workers against the health effects of exposure to hazardous substances, including limits on the airborne concentrations of hazardous chemicals in the air. [22] Most of OSHA's PELs were issued shortly after the adoption of the OSH Act in 1970.
Furthermore, OSHA has set permissible exposure limits [9] (PEL) on around 500 chemicals which are enforceable by law. These exposure limits include evidence that a certain amount of a chemical exposure is linked to one or more adverse health effects.
Furthermore, occupational exposure banding has become an important component of the Hierarchy of Occupational Exposure Limits (OELs). [3] [4] The U.S. National Institute for Occupational Safety and Health (NIOSH) has developed a process that could be used to apply occupational exposure banding to a broader spectrum of occupational settings.
