East Palestine, Ohio, is back in the news.
The city in southern Ohio was the site of a February train derailment involving rail cars carrying resin as well as vinyl chloride monomer, a PVC feedstock. Fire in the cars prompted emergency officials on-site to release the VCM to avoid a possible explosion, which then led to evacuation orders in the town.
The National Traffic Safety Board began two days of hearings June 22 to try to get to the bottom of what caused the freight cars to derail and whether the aftermath was handled properly.
You can watch the hearings on C-SPAN and NTSB's YouTube page and also access records and interviews with witnesses and experts. There's a lot to try to keep track of, and people with a lot more expertise than me will obviously have conclusions they can draw. For one example, an interview with an expert from Oxy Vinyls LLC — the company shipping the VCM — questions whether the company thought venting the chemical was needed.
The hearings will also cover: communication problems between emergency responders; freight car bearing failures; detection systems that were slow to pick up a fire in the moving train; and the damage and crashworthiness of the rail cars.
