The Occupational Safety And Health Act is administered by the Occupational Safety and Health Administration (OSHA). Safety and health conditions in most private industries are regulated by OSHA or OSHA-approved state systems. Employers must identify and eliminate unhealthful or hazardous conditions; employees must comply with all rules and regulations that apply to their own workplace conduct. Covered employers must maintain safe and healthful work environments in keeping with the requirements of the law. Effective OSHA safety and health regulations supersede others originally issued under these other laws: the Walsh-Healey Act, the Service Contract Act, the Contract Work Hours and Safety Standards Act, the Arts and Humanities Act and the Longshore and Harbor Workers’ Compensation Act.
