Regulating Transportation of Hazardous Substances: Railroads and Reform, 1883–1930

Abstract

The increase in volume of explosives and other hazardous materials transported by rail during the nineteenth century resulted in a growing number of accidents. In response, the Pennsylvania Railroad developed some of the first regulations governing the transport of such materials. In the twentieth century, a combination of enforcement difficulties and competitive pressures led the company, working through the American Railway Association, to press for industry-wide rules and enforcement, which resulted in the Association's, Bureau of Explosives. Similar motives impelled the carriers to seek federal regulation, which began in 1908. The Interstate Commerce Commission provided the legal authority in this public–private partnership, whilethe bureau took the lead in inspecting shipments, encouraging improvements in shipping techniques, and developing rules that formed the basis of all modern regulations of hazardous shipments.
