\"\"NTSB Issues Report on East Palestine Derailment<\/h2>\n

The National Transportation Safety Board (NTSB)<\/a> has issued their findings<\/a> on the East Palestine train derailment<\/a> that happened on February 3, 2023. The primary cause of the fiery crash was a defective wheel bearing. But other issues and decisions may have contributed to making the accident worse.<\/p>\n

What Happened in East Palestine<\/strong><\/h4>\n

The NTSB determined that during the trip, a wheel bearing on one of the tank cars overheated. This caused the axle to separate, derailing the train. Unfortunately, it also led to the puncture of a tank car containing flammable liquids. This car met a fairly low standard for strength, rated as a DOT-111 specification. The tanker started to leak, releasing a flammable liquid that rapidly caught on fire.<\/p>\n

The spilled liquid wasn\u2019t the biggest concern, however. The heat began to affect five other tank cars that contained a chemical called vinyl chloride. This chemical is not just flammable and toxic to people and the environment, but can, when overheated, undergo a chemical reaction called polymerization. This can result in a potentially explosive build-up of pressure inside the tank car.<\/p>\n

Therefore, a decision was made to \u201cvent and burn<\/a>\u201d \u2013 the cars were punctured to release the chemical, which was ignited outside the car to destroy as much of the vinyl chloride as possible. However, this resulted in the vinyl chloride that was incompletely burned being spread throughout the area. Byproducts of the combustion of the chemical, such as phosgene (a poison gas) and dioxins (persistent carcinogens) were created and entered the environment, increasing the hazard.<\/p>\n

While there were no immediate human fatalities due to the release, many inhabitants reported significant symptoms. Many animals (including pets) in the region died shortly after the release. And of course, the long-term effects are still to be fully determined.<\/p>\n

What Were the Causes of the Incident?<\/strong><\/h4>\n

Defective bearings called \u201chot boxes<\/a>\u201d have been known for decades as a cause of train accidents. Methods have been developed to monitor them and prevent them from leading to derailments. However, this didn\u2019t work in East Palestine. According to the NTSB, \u201c[a] hot bearing detector<\/a> traversed by train 32N detected an elevated temperature on the overheating bearing, but the low priority alert it transmitted to railroad personnel did not reflect the true condition of the failing bearing.\u201d This led to a failure in stopping the train to address the problem in time.<\/p>\n

Also, the type of rail cars used, while meeting legal standards, were the bare minimum required. Stronger tank cars than the DOT-111 might have prevented the initial release and fire and avoided the disaster.<\/p>\n

Other problems were noted regarding the emergency response. For example, according to the NTSB:<\/p>\n
