In 2003, the U.S. Fire Administration (USFA) announced a goal to reduce firefighter fatalities by 25 percent within 5 years and 50 percent within 10 years. It also committed to doing research that would support that goal. The consistently high annual percentage of fatalities related to fire department response and roadway scene operations prompted the USFA to look at several aspects related to these collisions in an effort to improve responder safety. Firefighters who are killed in privately owned vehicles (POVs) during the course of their duties account for the largest percentage of vehicle-related deaths. These are typically volunteer firefighters who are responding to or returning from emergency calls. However, career firefighters are also occasionally killed in POVs while performing their duties. The original edition of this “Traffic Incident Management Systems” (TIMS) report was released in 2008 as part of a cooperative agreement between the UFSA and the International Fire Service Training Association (IFSTA) at Oklahoma State University (OSU). The project was funded by the DOT Federal Highway Administration (FHWA). This latest edition of TIMS was developed in response to the release of the 2009 edition of the DOT/FHWA's Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD). It becomes evident that injuries and deaths that occur at roadway emergency scenes are a major concern to emergency responders. The purpose of this report is to focus on the causes of firefighter injuries and deaths when working on roadway incidents. This report will focus on the causes of these incidents and provide strategies for mitigating them in the future. The occurrence and severity of these incidents can be reduced through proper roadway incident scene tactics and incident management, information which will be covered in the remaining chapters of this document.
