On July 28, 2003, at approximately 1730 hours, a 23-year-old male volunteer lieutenant (the driver/victim) was killed and a 19-year-old male volunteer fire fighter (the passenger) was seriously injured during a single-vehicle rollover crash while responding in a privately owned vehicle (POV) to a confirmed trailer fire. The POV was traveling southbound an estimated 80 miles per hour (mph) on a two-lane State road when it drifted off the right side of the roadway. The lieutenant lost control after he apparently overcorrected while attempting to bring the POV back onto the roadway. The POV overturned several times, struck a wood utility pole, and ejected both fire fighters. Emergency medical services responded within minutes of the incident, and the victim was flown to the hospital via life-flight helicopter where he was pronounced dead. The passenger was transported to the hospital via road ambulance. NIOSH investigators concluded that, to minimize the risk of similar occurrences, fire departments should: 1. review, and revise if appropriate, Standard Operating Guidelines (SOGs) to explicitly require mandatory use of seatbelts in privately owned vehicles (POVs) during emergency response; and, 2. develop or revise, as appropriate, and enforce SOGs for the use of privately owned vehicles for emergency response, and provide training on the SOGs to fire fighters in all new-member orientation and driver training sessions.
