The railroad industry formed the Bureau of Explosives (BOE) in 1907 as a self-policing agency to advance the safe transportation of explosives and other dangerous articles. In fact, the BOE developed the first hazmat safety rules, which the U.S. Department of Transportation (DOT) later expanded upon. Today, the BOE remains dedicated to helping carriers, shippers and container manufacturers continually improve hazardous materials transportation safety.
