Which organization typically enforces legally binding exposure limits known as OELs in the United States?

Explanation:
In the United States, legally binding exposure limits for workers are set and enforced by OSHA. These limits, known as Permissible Exposure Limits (PELs), come from the Occupational Safety and Health Act and are enforceable through inspections, citations, and penalties to ensure workplaces limit hazardous airborne concentrations over time. ACGIH provides Threshold Limit Values as guidelines that help assess risk and guide control measures, but they aren’t legally enforceable. NIOSH offers Recommended Exposure Limits based on research, intended to inform safety decisions, but these RELs are not law. The EPA handles environment-focused exposure limits for pollutants and pesticides, not the standard occupational exposure limits that apply directly to workplaces.
