Exactly 533 firefighters from refineries and other industries worldwide attended the 48th annual TEEX Industrial Fire School conducted the week of July 18, 2010, at the Brayton Fire Training Field in College Station. The largest of the live-fire training props tackled by the visiting firefighters was Prop 31 - the process unit.

The unit stands 66 feet tall and is a multi-level prop encompassing 21,608 square feet. It boasts six fixed monitors and burns LPG and E3 fuel. It contains 18 dual-fuel leak points, although not all are lit at once. The valve station controlling the project is 12 feet wide to accommodate the large number of valves involved.

Prop 31 can simulate various scenarios such as a process sump fire, truck-loading area fire and various other process unit-related emergency situations. Cost of the new prop built in 2008 exceeded $1 million.
