REGULATIONS|Federal Regulatory Program Lists

List: Air Contaminants (Occupational and Safety Health Act)
Description
The Occupational and Safety Health Act (OSHA) establishes the federal regulatory framework for the control of workplace safety. OSHA's goal is to make sure employers provide their workers a place of employment free from recognized hazards to safety and health, including exposure to toxic chemicals. OSHA establishes permissible exposure limits (PELs) to regulate workplace exposure to air contaminants.

The universe of substances covered by OSHA PELs has largely been determined by whether a substance has a Threshold Limit Value (TLV), a voluntary exposure standard developed by the American Conference of Governmental Industrial Hygienists (ACGIH).
