Acute Hazardous-Events Data Base. Interim report (Final)

This document contains summaries of records of 3,121 accidental releases of hazardous substances. Because of sampling, these records represent a larger population of 6,928 events. One section describes the background and methodology. Another discusses the 468 events associated with the reported 4,717 injuries and 138 deaths. Other sections summarize the events as a whole, with attention to end effects, causes and quantities. A section considers large-scale atmospheric releases, assessing similarities to the Bhopol accident. Appendices contain the data coding procedures; summary data base profiles; a list of chemicals reportedly released; summary statistics for events with reported deaths of injuries and for events with spills or vapor releases, but not fires or explosions; and a brief listing of all events with reported deaths or injuries.
