What is the maximum permissible exposure limit (PEL)?

The maximum permissible exposure limit (PEL) refers specifically to the legal limit established by OSHA for exposure to a hazardous substance in the workplace over a specific period. The PEL is designed to protect workers from health risks associated with prolonged exposure to hazardous substances, such as chemicals or airborne contaminants. This limit is often determined based on research into the toxicology of the substance, allowing for a baseline that employers must adhere to in order to ensure the safety and health of their employees.

By defining PEL as the legal limit for exposure, OSHA sets enforceable standards to which companies must comply, making it a critical aspect of workplace safety regulations. These limits are legally enforceable under the Occupational Safety and Health Act, positioning them as a key instrument in promoting workplace health.

In comparison, maximum concentration levels, recommendations for ventilation, or specific decibel levels pertain to different standards or guidelines that address safety but do not define the legal threshold for chemical exposure as the PEL does.
