What is the OSHA permissible exposure level for lead?

The Occupational Safety and Health Administration (OSHA) has established a permissible exposure limit (PEL) for lead in the workplace, which is set at 50 micrograms per cubic meter of air (µg/m³) averaged over an eight-hour work shift. This regulation is designed to protect workers from the harmful effects of lead exposure, which can lead to serious health issues, including neurological damage, kidney damage, and other health problems.

This specific limit is grounded in comprehensive research on the health effects of lead and is intended to minimize risk to workers. The chosen answer reflects well-established safety standards aimed at creating a safer working environment in industries where lead exposure may occur.

The other options presented do not align with the OSHA regulation regarding lead exposure limits. Each of those alternative values is lower than the established PEL, which may lead to a misunderstanding of safety requirements for lead exposure in the workplace. This highlights the importance of familiarity with current regulatory standards in maintaining health and safety compliance.
