Based on data from the Consumer Product Safety Commission's (CPSC) National Electronic Injury Surveillance System, fireworks-related injuries accounted for an estimated 12,400 emergency room visits during 1990 in the United States (1); two thirds of fireworks-related injuries occur during the 4-week period surrounding Independence Day. Since 1986, to better characterize fireworks-related injuries and to improve local health education and prevention efforts, the Marion County (Indiana) Health Department (MCHD) has conducted surveillance of fireworks-related injuries. This report summarizes surveillance results for 1986-1991.
