Confusion on sensor planes abilities delayed response in Ohio train derailment, report says

A report from the EPA's Inspector General highlights that confusion about a specialized sensor plane's capabilities delayed the response to the East Palestine train derailment. The ASPECT plane, which was deployed late, can detect temperature differences of less than 1 degree, contrary to the on-scene coordinator's belief of 20-30 degrees. This misjudgment resulted in the unnecessary venting and burning of five rail tank cars containing vinyl chloride, leading to a hazardous fire that prompted evacuations. The National Transportation Safety Board previously criticized Norfolk Southern for not sharing crucial safety information regarding the chemical. Residents have expressed ongoing health concerns, fearing long-term effects from exposure to the toxic chemicals.

The EPA maintains that no dangerous chemical levels were detected after the evacuation order was lifted, despite lingering doubts among locals. Robert Kroutil, who worked on the ASPECT technology, emphasized that accurate temperature data could have changed the response strategy. In light of these findings, the EPA plans to enhance its training and understanding of advanced monitoring tools for future incidents.
