The Permissible Exposure Limit (PEL or OSHA PEL) is a legal limit in the United States for personal exposure to a substance, usually expressed in parts per million (ppm). Workers may not be exposed to greater than this concentration during any eight-hour workshift. Permissible Exposure Limits are defined by the Occupational Safety and Health Administration (OSHA).
