Occupational Safety and Health Administration (OSHA). OSHA has three stated goals that serve as the cornerstones of its policies and regulations: 1) Improve the safety and health for all workers, as evidenced by fewer hazards, reduced exposures, and fewer injuries, illnesses, and fatalities; 2) Change workplace culture to increase employer and worker awareness of, commitment to, and involvement in safety and health; 3) Secure public confidence through excellence in the development and delivery of OSHA's programs and services. The federal guidelines imposed by this agency are complemented by state regulations that are often tougher than those proposed by OSHA.
