What does the Occupational Health Safety Administration do?

The US Occupational Safety and Health Administration promulgates regulations related to maintenance of minimum safety and health conditions in the workplace, inspects covered workplaces for compliance with regulations or when a fatality or other serious incident has happened, issues citations and fines for failure to comply with regulations, and investigates whistle-blower complaints under some 24 Federal Laws (many of which are not related to occupational health and safety).
