"Crude oil that is extracted and shipped from eastern Montana, western North Dakota, and parts of the Canadian prairie provinces is named Bakken crude. In recent months, it has become front page news as both an energy source and hazardous material. A train derailment in Lac-Megantic, Quebec, resulted in 47 deaths and nearly wiped out the small community's downtown area, while incidents in North Dakota, Alabama and Virginia have fueled first responder concerns. The U.S. Department of Transportation (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has been working with government agencies, shippers, first responders and private sector groups to address the hazards associated with the raw product in transportation. Bakken crude is considered a 'light, sweet crude' because of its low sulfur content. Light, sweet crude oil is typically assigned a DOT Packing Group I or II classification in accordance with federal regulations. These packing groups mean that the material's flash point is below 73 F (22.7 C); for Packing Group I materials, the boiling point is below 95 F (35 C). This means the materials pose significant fire risk if released from the package during an accident."
