Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA's role is to ensure these conditions for America's working men and women by setting and enforcing standards, and providing training, education and assistance. The same Act charges the National Institute for Occupational Safety and Health (NIOSH) with recommending occupational safety and health standards. NIOSH communicates these recommended standards to regulatory agencies (including OSHA) and to others in the occupational safety and health community through the publication and dissemination of Criteria Documents such as the Criteria for A Recommended Standard - Occupational Noise Exposure.
