In Tucson last year, a collision between a pickup truck and tractor trailer spilled nearly 4,500 gallons of gasoline, igniting the tanker and killing the passengers in the pickup. In March 2011, it took three hours and 80,000 gallons of water to contain a fuel tanker fire on a highway shoulder near Parker. The driver survived with a broken wrist and pelvis. The fire eventually burned out on its own and the environmental damage was contained with sand. And in September 2007, a tractor trailer hauling 8,500 gallons of diesel fuel flipped over after striking a highway center divide near Payson.
