Occupational health clinics provide medical services for workers who may have work-related health problems. They focus on the prevention of occupational illnesses and injuries, and promote a worker’s physical, mental and social well-being. OHCs can also identify workplace factors which are detrimental to the health and well-being of workers, provide occupational health and ergonomic information to increase knowledge among workers, employers and the general public; and provide services designed to produce changes to improve workplaces and the health of workers.
