For example, in the United States the Occupational Safety and Health Administration (OSHA) reports that every year work-related accidents and illnesses cost an estimated 56,000 American lives. On an average day, 17 people are killed in safety accidents, 16,000 are injured, and 137 die from occupational disease. Each year, 700,000 days are lost to injuries and illnesses related to musculoskeletal disorders because of overuse of particular parts of the body. It is estimated that safety accidents alone cost the American economy over $100 billion a year.
