The specific objective of this study was to identify all of the on-duty firefighter fatalities that occurred in the United States in 1995, and to analyze the circumstances surrounding each occurrence. The study is intended to help identify approaches that could reduce the number of deaths in future years. In addition to the 1995 findings, this study includes a special analysis of the use of personal alert safety devices at fatal structure fires and a special report on several fatalities that occurred during technical rescue operations.
