What is the action level for lead in air according to OSHA guidelines?

The action level for lead in air, according to OSHA guidelines, is indeed 30 micrograms per cubic meter (ug/m3). This level is established to ensure the safety of workers who may be exposed to lead in their occupational environments. When lead exposure in the air reaches this action level, it triggers certain requirements, such as the implementation of monitoring, medical surveillance, and protective measures to minimize exposure. This regulation is crucial in protecting workers from the potential health risks associated with lead, including neurological damage, respiratory issues, and other serious health concerns.
