The Occupational Safety and Health Administration (OSHA) is a U.S. government agency that is part of the Department of Labor, responsible for ensuring safe and healthy working conditions for employees. OSHA sets and enforces workplace safety and health standards, provides training and education, and assists employers in developing safer work environments. OSHA regulations cover a wide range of workplace hazards, including physical, chemical, biological, and ergonomic risks. The agency also conducts inspections and investigations to ensure compliance with these standards and may issue citations or penalties for violations. OSHA aims to reduce workplace injuries, illnesses, and fatalities through prevention, education, and regulatory enforcement.
