WASHINGTON — Warning that a “major loss of life” could result from an accident involving the increasing use of trains to transport large amounts of crude oil, U.S. and Canadian accident investigators urged their governments Thursday to impose new safety rules.
The unusual joint recommendations by the U.S. National Transportation Safety Board and the Transportation Safety Board of Canada include better route planning for trains carrying hazardous materials to avoid populated and other sensitive areas.
They also recommended stronger efforts to ensure hazardous cargo is properly classified before shipment, and greater government oversight to ensure rail carriers that transport oil are capable of responding to “worst-case discharges of the entire quantity of product carried on a train.”
The NTSB also noted that it is still waiting for final action from government regulators on new requirements to improve the safety of tank cars used to transport oil. The safety board called for changes in the DOT-111 tank cars, which are used for a variety of flammable liquids, after a 2009 accident in Cherry Valley, Ill. The rules aren’t expected to be ready until next year.
Last month an oil train derailed and exploded near Casselton, N.D., creating intense fires. The accident occurred about a mile outside the town, and no one was hurt, but about 2,000 people were evacuated to avoid toxic smoke. Rail lines run through and alongside the town.
In July, a runaway oil train derailed and exploded in Lac-Megantic, Quebec, near the Maine border. Forty-seven people were incinerated and 30 buildings destroyed.
The NTSB noted that crude oil shipments by rail have increased by more than 400 percent since 2005. Some oil trains are more than 100 cars long.
“The NTSB is concerned that major loss of life, property damage and environmental consequences can occur when large volumes of crude oil or other flammable liquids are transported on single train involved in an accident,” NTSB said.
