Injured at work? An interesting, informative site will give you a good start. All 50 States' and D.C.'s Home Pages and Workers' Compensation Agencies. This site has Workers' Compensation Sites for every state in the union as well as related state specific links.
Additionally, there is a great website for the National Institute for Occupational Safety and Health (powered by the CDC) which provides a wealth of information for the prevention of illness and injuries at work. Literally a ton of very valuable and potentially life saving information.
