On December 2, 2005, a male career Captain (the victim) died, and a male driver/operator and a male fire fighter suffered severe injuries when their apparatus struck a passenger van at a four-way intersection, left the road and overturned 1¼ times. The crew was responding Code 3 (lights and sirens) to a reported gas leak when the incident occurred. The permanent stop lights had been replaced by temporary traffic control stop signs at the intersection as a result of an extended power outage caused by Hurricane Katrina. NIOSH investigators concluded that, to minimize the risk of similar occurrences, fire departments should: 1. provide members with safety advisories highlighting hazardous situations that may be encountered while responding to, working on the scene, or returning from emergency calls; 2. provide refresher training on and enforce standard operating procedures (SOPs) for emergency vehicle operations, including the use of seatbelts; 3. ensure that drivers of emergency apparatus come to a complete stop at intersections having a stop sign or a red signal light before proceeding through the intersection. In addition, state and local authorities having responsibility over local roadways should ensure that temporary traffic control devices and traffic control signals are in compliance with the standards set forth in the Manual on Uniform Traffic Control Devices (MUTCD).
