ARCCA was asked to investigate an accident where a dump truck, while dumping mulch, knocked the cap off a buried propane tank. The resulting explosion not only destroyed the truck, but also killed the driver. Our expert inspected an exemplar dump truck and measured its clearance, as well as the clearances of all the other farm vehicles. He inspected the site’s layout relative to the tank burial and compared it to the township and other regulatory authorities’ regulations for tank location and protection. He determined that the tank was too close to a roadway to not have been protected by bollards.
