Investigators probing the poisonous practice catastrophe in East Palestine, Ohio, are reviewing a number of movies of the practice previous to it derailing.

One video exhibits “what appears to be a wheel bearing in the final stage of overheat failure moments before the derailment,” the National Transportation Safety Board mentioned in a press release Tuesday.

“The suspected overheated wheel bearing has been collected and will be examined by engineers from the NTSB Materials Laboratory in Washington, D.C,” the assertion mentioned.

The wheelset will endure a metallurgical examination as a part of the general investigation. Investigators will return to finish an examination of the tank automobiles as soon as they’re totally decontaminated, the NTSB mentioned.

Investigators haven’t but decided what they consider brought about the catastrophe. Such a dedication sometimes takes many months.

The NTSB mentioned it’s reviewing different movies, too, together with footage from two native companies reported by native media to indicate glowing or flames from the practice previous to the derailment.

The company can be reviewing recording knowledge from the practice’s so-called black packing containers, together with an occasion recorder and picture recorders.

The practice carrying hazardous supplies, together with the poisonous chemical vinyl chloride, derailed February 3, prompting evacuation orders for residents within the village of 5,000 individuals close to the Pennsylvania border.

The wreckage burned for days as authorities fearful about the opportunity of a widespread, lethal explosion. But crews managed managed detonations to launch the chemical, which might kill rapidly at excessive ranges and improve most cancers danger. The hazardous substance spilled right into a trench, the place it was burned away.

The state’s public utilities fee advised Ohio Gov. Mike DeWine that the practice was not thought-about a “high hazardous material train,” DeWine advised reporters Tuesday, an assertion he mentioned he discovered “absurd.”

If that’s appropriate, he mentioned, “Congress needs to take a look at how these things are handled. We should know when we have trains carrying hazardous material that are going through the state of Ohio,” DeWine mentioned.

In an replace Tuesday, investigators mentioned no vinyl chloride has been detected in any of the down-gradient waterways close to the practice derailment, and environmental groups are aerating waterways close to the location.

While there are some waterways that stay contaminated, the Ohio Environmental Protection Agency is assured that the contaminants are contained, mentioned Tiffany Kavalec, chief of the division of floor water on the company.

What Kavalec described as “fire combustion chemicals” did stream to the Ohio River, “but the Ohio River is very large, and it’s a water body that’s able to dilute the pollutants pretty quickly,” she mentioned.

The chemical compounds are a “contaminant plume” that the Ohio EPA and different companies have been monitoring in actual time. It’s believed to be shifting a few mile an hour, Kavalec mentioned.

The “tracking allows for potential closing of drinking water intakes to allow the majority of the chemicals to pass. This strategy, along with drinking water treatment…are both effective at addressing these contaminants and helps ensure the safety of the drinking water supplies,” Kavalec mentioned, including that they’re fairly assured that the “low levels” of contaminants that stay are usually not getting handed onto prospects.

Still, authorities are strongly recommending that folks within the space use bottled water for ingesting, particularly if their water is from a non-public supply, resembling a effectively.

About 3,500 fish throughout 12 totally different species have died in Ohio’s waterways following the spill, Mary Mertz, the director of Ohio’s Department of Natural Resources, mentioned.

None of the 12 species affected are endangered or threatened, nevertheless it’s “still a loss of life, all the same,” she mentioned.

The estimation of the lifeless fish got here after preliminary testing and sampling by the state company, Mertz mentioned. There doesn’t seem to have been a rise within the variety of fish killed because the first couple of days following the derailment.

There has been no proof of non-aquatic species affected by the derailment, she mentioned, they usually haven’t had any issues about that.

Almost 500 cubic yards of “vinyl chloride-impacted material” has been eliminated, in response to the Ohio EPA, and cleanup of contaminated dust close to the derailment web site continues.

Some of the pits of dust which were dug up measure about 700 ft lengthy and eight ft deep, Kurt Kollar, the on-scene coordinator for the Ohio EPA’s Office of Emergency Response, mentioned.

Almost 1,000,000 gallons of water have been collected and saved in containers on web site, Kollar mentioned.

By subsequent week, most “high-end, daily” emergency environmental responses ought to be of their last phases, he mentioned.

When requested about anecdotal reviews of individuals getting complications and sore throats, and of animals, resembling cats and chickens, dying close to the practice derailment, Ohio Health Director Dr. Bruce Vanderhoff mentioned that air high quality doesn’t look like the supply.

“Anecdotes are challenging because they’re anecdotes,” Vanderhoff mentioned. “Everything that we’ve gathered thus far is really pointing toward very low measurements, if at all.”

People with these signs ought to contact their medical supplier and name the native hotline so a crew can examine that setting, he mentioned.
