Permissible Exposure Limit

What Does Permissible Exposure Limit Mean?

Permissible exposure limit (PEL) is the legal limit in the U.S. for maximum concentration of any chemical in the air to which a worker may be exposed continuously for eight hours without any danger to health and safety. PEL is established by the Occupational Safety and Health Administration (OSHA).

Safeopedia Explains Permissible Exposure Limit

Permissible exposure limit is observed in workplaces to maintain a safe work environment for workers. These limits are not distinct lines between safe and dangerous and are reviewed from time to time as new information about chemicals emerges. It is therefore recommended that employers always aim to reduce the concentration of chemicals in the air and that workers use personal protective equipment (PPE) when working in such an environment.
