SCENARIO
It was a typical August day, sun shining, hot and humid, with a light breeze blowing from the south west. A transport tanker, hauling ethanol, was headed north on U.S. 41, and in the process of making a left turn onto U.S. 136. The driver of the tanker apparently did not see the southbound truck approaching the intersection. This truck was carrying a load of sodium hydroxide. The southbound driver, realizing there was to be an impact, veered his vehicle to the right, skidding sideways into and capsizing the tank truck.

SCENARIO (cont’d)
A valve on the tanker popped open, permitting some ethanol to escape on the ground. After the impact, the southbound truck lost some containers of sodium hydroxide. Sparks from the tanker ignited the fuel. The fire and heat from the fire created a plume while heating the sodium hydroxide.
