Workers' Memorial Day, April 28, was established in 1989 as an international day of remembrance for workers who died or were injured on the job. This day also commemorates the 34th anniversary of the National Institute for Occupational Safety and Health and the Occupational Safety and Health Administration, both of which were created by the U.S. Occupational Safety and Health Act. On average, in the United States, nearly 11,000 workers are treated in emergency departments each day, and approximately 200 of these workers are hospitalized. An estimated 6,300 private-sector workers require time away from their jobs, 15 workers die from their injuries, and 134 die from work-related diseases. These losses account for nearly $73 billion in workers' compensation. International and national prevention practices during the preceding 3 decades have reduced these losses, but morbidity and mortality from occupational hazards are still a major social and economic burden.
