Back injuries are a primary source of workers’ comp claims and legal disputes over disability. But you don’t have to wait for trouble. The American College of Occupational and Environmental Medicine has a checklist to help you train workers to stay healthy. It provides a series of preventive strategies that reduce the odds of injury. Examples include providing regular rest breaks for employees who do strenuous physical work, having them alternate between standing and sitting tasks and using equipment that stops potentially harmful vibrations.
