The US Chemical Safety and Hazard Investigation Board began operations in 1998 with the stated mission to promote the prevention of major chemical accidents at fixed facilities. The independent, scientific investigative agency's Web site contains historical and current data, reports, and other information on chemical accidents from around the nation. For example, on September 13, 2002, a chemical plant explosion occurred in Freeport, Texas, involving an explosion, fire, and release of chemicals to the environment. The entry contains which specific chemicals were involved and a brief report of the incident, as well as injury, containment, and other relevant information.
