The fire was caused by the ignition of hydrocarbon vapor released during the off-loading of basic sediment and water (BS&W) from the two vacuum trucks into an open area collection pit. BS&W is an oil/gas exploration and production (E&P) waste liquid. The BS&W was contaminated with highly flammable condensate. During the off-loading, vapor off-gassed from the BS&W and was drawn into the air intakes of the vacuum trucks' running diesel engines. As a result, the engines began to race and backfire.
FVIR ((Flammable Vapor Ignition-Resistant) Water Heaters. Natural gas and propane (LP) fired water heaters have caused fires in some homes where flammable liquids such as gasoline have been poorly handled near the water heater. Gas spills can be ignited by the water heater burner. As a result, design improvements have been made to residential water heaters to reduce this problem. All water heaters now produced in North America are Flammable Vapor Ignition-Resistant (FVIR) types. Timing.
