What is the purpose of permissible exposure limits (PELs) established by OSHA?

The purpose of permissible exposure limits (PELs) established by OSHA (Occupational Safety and Health Administration) is to protect workers from toxic exposures. These limits are set to regulate the maximum amount or concentration of a substance that an employee can be exposed to in the workplace over a specified period, typically an eight-hour workday. By establishing these limits, OSHA aims to minimize the risk of adverse health effects caused by hazardous substances, ensuring a safer working environment for employees. PELs are based on research and data regarding the potential health impacts of various chemicals, serving as a critical component of occupational health and safety regulations.
