Chinanews.com, February 6 (Xinhua) According to CBS reports, on the evening of the 3rd local time, about 50 train carriages near the junction of Ohio and Pennsylvania were seriously derailed due to mechanical failure of the train axle and caused a fire.
The derailed carriage contained dangerous goods, and nearby residents were being evacuated.
Rail operator Norfolk Southern said 20 of the more than 100 carriages carried dangerous goods, including flammable, combustible and environmental hazards.
At least one of the cars will be "intermittently released" of its contents via a pressure release device.
On the evening of February 3, local time, a train derailed in Northeast Ohio, USA, followed by a fire. The picture shows part of the train burning at the scene of the accident.
The National Transportation Safety Board said only 10 of the derailed cars contained hazardous materials, and five of them contained vinyl chloride.
Officials have previously stressed that no other leaks related to vinyl chloride have been identified beyond the pressure relief device, which was operating as designed.
Vinyl chloride may lead to an increased risk of liver and other cancers, according to the National Cancer Institute.
Norfolk Southern will subsequently provide a fact sheet listing all the chemicals involved.
Youngstown Mayor Trent Conaway emphasized that the air quality detectors far from the fire site did not show any worrying data, and the water resources in the incident area are also safe because it comes from groundwater, not Affected by pollutants entering streams.
Currently, environmental agency staff are removing pollutants from the stream and monitoring the water quality.
Residents within a 1.6-kilometer radius of the incident will be evacuated, officials said.
On the 5th local time, the police went door to door to count the number of remaining residents and urged people in the evacuation area to leave.
The evacuation order reportedly covered the homes of 1,500 to 2,000 residents in the town, though it was unclear exactly how many people were actually affected.
Emergency crews are monitoring the fire and say remedial work cannot be done as long as smoke is rising from the compartment.
