What is the PEL (Permissible Exposure Level) for lead according to OSHA?

The Permissible Exposure Level (PEL) for lead, as established by OSHA, is set at 50 μg/m3 over an 8-hour workday. This standard is designed to protect workers from the harmful effects of lead exposure, which can lead to serious health issues, including neurological damage and various other acute and chronic health conditions.

In the context of occupational safety, this PEL provides a threshold that, when exceeded, could require employers to implement additional safety measures and exposure monitoring to ensure that workers' health is protected. The level is based on a comprehensive assessment of available data regarding lead's toxicity and risk of exposure in the workplace.

The other options listed do not align with the established PEL defined by OSHA and therefore do not accurately reflect the limits set for lead exposure in the occupational environment.
