On November 16, 2000, a 19-year-old male volunteer fire fighter (the victim) died and a 17-year-old junior fighter was injured when the victim lost control of the tanker truck (Tanker 63) he was driving. At 1900 hours, the fire department began performing a water shuttle training exercise. At approximately 2000 hours, the victim was driving Tanker 63 en route to the station with the junior fire fighter as a passenger. Tanker 63 was traveling eastbound on a two-lane state road when it drifted off the east edge of the roadway. The victim steered it back onto the roadway. The tanker traveled a short distance on the center line before the victim lost control after he overcorrected in an attempt to steer the tanker back into the right eastbound lane. The tanker left the right (east) roadway and traveled down an embankment and through a ditch line. The tank separated from the chassis, became airborne and rotated approximately 180 degrees before landing on the ground, while the truck overturned and rolled upside down before coming to rest on its top. The junior fire fighter was ejected from the tanker and sustained serious injuries. The victim was trapped inside the cab of the truck. He was removed and taken to a local hospital where he was pronounced dead. NIOSH investigators concluded that, to minimize the risk of similar occurrences, fire departments should: ensure all drivers of fire department vehicles are responsible for the safe and prudent operation of the vehicles under all conditions; enforce standard operating procedures (SOPs) on the use of seatbelts in all emergency vehicles. Additionally, fire departments and apparatus constructors should ensure that second unit body mounting systems are of substantial design and construction.
