Each year, approximately 6300 workers in the United States die from work-related injuries; costs of such injuries exceed $83 billion annually. In addition, an estimated 50,000-70,000 workers die each year from occupational diseases. To honor those who have died from occupational injuries or diseases and to recognize opportunities to prevent these deaths, April 28, 1994, has been designated Workers' Memorial Day. Workers' Memorial Day was initiated by the American Federation of Labor-Congress of Industrial Organizations (AFL-CIO) and designated by Congress in 1989. Additional information on causes and prevention of work-related injury and disease is available from CDC's National Institute for Occupational Safety and Health. Addendum.
