Forensic Investigations of Propane-Related Food Truck Incidents

Abstract

The proliferation of propane-fueled food trucks and concession trailers over the last decade has led to a fast-growing industry. As with many nascent industries, accidents accompany the surge in growth, and the food truck industry is no exception. Numerous propane-related fires, flash fires, and explosions have resulted in property damage, business interruption, injury, and death. Conducting a proper investigation of a food truck incident is essential in determining the origin/cause and ultimately assigning liability and preventing recurrences. This paper discusses the food truck industry as well as the design, construction, and layout of the trucks. It provides an overview of the gas systems installed in the vehicles — from the cylinder or tank to the appliances, properties of propane, and relevant codes and standards applicable to food trucks that utilize propane. Finally, an outline of the proper methodology to use when investigating a food truck incident is pro-vided, and a food truck explosion case study is presented.
