Permissible Exposure Limit
The permissible exposure limit (PEL) for lead in the workplace is 50 micrograms per cubic meter of air, averaged over an 8-hour workday. This limit is set by the Occupational Safety and Health Administration (OSHA) to protect workers from the health effects of lead exposure. Employers must take measures to ensure that workers are not exposed to lead levels above the PEL.
The Permissible Exposure Limit (PEL) for hydrochloric acid is set by the Occupational Safety and Health Administration (OSHA) at 5 parts per million (ppm) as an 8-hour time-weighted average. This limit is based on protecting workers from potential health effects associated with exposure to hydrochloric acid in the workplace.
The permissible exposure limit for respirable dust containing crystalline silica is 0.05 mg/m3 as recommended by the National Institute for Occupational Safety and Health (NIOSH) and the American Conference of Governmental Industrial Hygienists (ACGIH). This limit is intended to protect workers from the health risks associated with exposure to crystalline silica, which can cause silicosis and other respiratory diseases.
OSHA
The OSHA Limit (PEL or Permissible Exposure Limit) is that concentration of a hazardous material in air above which an employee may not be exposed without violating the OSHA regulation on employee exposure. Most OSHA limits were taken from consensus exposure standards in place in 1970 and have not been revised to take notice of knowledge that has been developed since then.
