True or False: The PEL for benzene is a guideline for safe exposure levels.

The statement is true because the Permissible Exposure Limit (PEL) for benzene is established as a regulatory guideline that indicates the maximum allowed concentration of benzene in the workplace over a specific time period. The PEL is designed to ensure that workers are not exposed to harmful levels of benzene, which is a known carcinogen and poses significant health risks, including effects on the blood and immune system.

Setting a PEL involves scientific research and regulatory review to determine what concentration levels are considered safe for human exposure over time. Therefore, adhering to the PEL helps in protecting workers' health and preventing occupational diseases. This guideline is critical for industries that handle or use benzene, ensuring that appropriate safety measures are implemented to reduce exposure risks.
