    This document is provided by the Agency for Toxic Substances and Disease Registry (ATSDR) ONLY as an historical reference for the public health community. It is no longer being maintained and the data it contains may no longer be current and/or accurate.

    The Hazardous Substances Emergency Events Surveillance (HSEES) system, maintained by the Agency for Toxic Substances and Disease Registry (ATSDR), actively collects information to describe the public health consequences of acute releases of hazardous substances in 15 states. This report summarizes the characteristics of events reported to ATSDR by all participating state health departments in 2004. Information about acute events involving hazardous substances was collected, including the substance(s) released, number of victims, number and types of injuries, and number of evacuations. The data were computerized using an ATSDR-provided Web-based data entry system.

    A total of 7,744 events was reported. In 6,835 (88.3%) events, only one substance was released. The most commonly reported categories of substances were other inorganic substances (excluding chemicals in the categories of acids, bases, ammonia, and chlorine), volatile organic compounds, and mixtures involving substances from different categories that were mixed or formed from a reaction before release. During this reporting period, 620 events (8.0% of all reported events) resulted in a total of 1,838 victims, 41 of whom (2.4%) died. The most frequently reported injuries were respiratory irritation, headaches, and dizziness/central nervous system symptoms. Evacuations were ordered for 499 (6.4%) events.

    Findings regarding the percentage of events involving victims and the distribution of types of injuries reported have been consistent in recent years. Topics targeted in 2004 included

    1) disaster preparedness, 2) methamphetamine lab awareness activities, 3) outreach to specific groups using ammonia, chlorine, cleaning products, acids, and mercury, 4) outreach to targeted populations including children, responders, the transportation industry, and 5) special interest topics including carbon monoxide poisonings from underground utility fires and exposure to tearing agents from theft deterrent devices.
