What is the OSHA action level for exposure to lead?

The OSHA action level for exposure to lead is set at greater than or equal to 30 micrograms per cubic meter (ug/m^3) of air averaged over an 8-hour workday. This level is significant because it triggers specific requirements for employers to implement additional protective measures to minimize worker exposure to lead. When concentrations reach this action level, employers need to monitor lead levels in the workplace, assess the risks, and begin implementing control measures to ensure the health and safety of their workers.

This action level reflects OSHA's commitment to limiting lead exposure, as lead is a toxic metal that can cause serious health issues, including neurological damage and other systemic effects. Maintaining lead exposure below this action level helps protect workers from these adverse effects and ensures compliance with safety regulations.
