| 摘要： | On March 10, 2017, about 12:50 a.m., central standard time, an eastbound Union Pacific Railroad (UP) unit ethanol train with 3 locomotives, 98 loaded tank cars, and 2 buffer cars derailed near milepost 56.8 at a timber railroad bridge near Graettinger, Iowa. Twenty loaded tank cars derailed. Fourteen of the derailed tank cars released about 322,000 gallons of undenatured ethanol, ethyl alcohol without a denaturant added to it, fueling a postaccident fire. The accident occurred near Jack Creek. There were no injuries and three nearby homes were evacuated. About 400 feet of railroad track and a 152-foot railroad bridge were destroyed in the accident. UP estimated damages, excluding environmental remediation or the cost of clearing the accident, at $4 million. The investigation focused on the following safety issues: the adequacy of UP’s track maintenance and inspection program, the adequacy of the Federal Railroad Administration (FRA) oversight, and the transportation of fuel ethanol without the use of volatile organic chemical denaturants. As a result of this investigation, the National Transportation Safety Board (NTSB) makes new safety recommendations to the FRA, the Pipeline and Hazardous Materials Safety Administration (PHMSA) and UP. The NTSB is also reiterating an existing safety recommendation to PHMSA. |
