What is the primary purpose of establishing PELs by OSHA?

The primary purpose of establishing Permissible Exposure Limits (PELs) by the Occupational Safety and Health Administration (OSHA) is to minimize exposure to hazardous substances. PELs are regulatory limits on the concentration of substances in the air that workers can be exposed to during their workday. By setting these limits, OSHA aims to protect workers from the harmful effects of various toxic chemicals and substances, ensuring a safer work environment. This not only helps to prevent immediate health issues but also addresses long-term health risks associated with chronic exposure to hazardous substances.

While OSHA is concerned with workplace safety and health, promoting environmental conservation, regulating transportation of hazardous materials, and providing medical guidelines are functions served by other organizations or regulations and do not fall under the primary focus of PELs. Establishing PELs serves as a critical component in safeguarding worker health and establishing clear standards for what constitutes safe exposure levels in the workplace.
