How are OSHA regulations different from EPA regulations?

OSHA and EPA regulations address different aspects of industrial air quality. OSHA focuses on protecting workers from airborne hazards inside the facility by regulating workplace exposure. The EPA regulates what facilities emit outside into the environment through air emissions standards.

For example:

• OSHA: worker exposure to weld fumes, dust and oil mist inside the plant
• EPA: exhaust emissions and hazardous air pollutants released into the surrounding environment

Depending on the process and industry, manufacturers may need to comply with both.
