The February 3, 2023 derailment in East Palestine, Ohio resulted in the release of which hazardous chemical?

• A. Vinyl chloride
• B. Ammonium nitrate
• C. Benzene
• D. Hydrogen sulfide

Answer: (A)

During the East Palestine derailment, the train cars carrying vinyl chloride derailed and caught fire. To prevent a catastrophic explosion from the pressurized tanker cars, authorities decided to perform a controlled release and burn of the vinyl chloride. That deliberate burn released vinyl chloride gas into the air, making it the hazardous chemical involved in this incident. Vinyl chloride is a volatile, toxic chemical used to make PVC, and its release requires protective action and monitoring due to inhalation risks and potential byproducts from burning. The other chemicals listed—ammonium nitrate, benzene, and hydrogen sulfide—were not the substances released in this event, though they have their own separate hazards in different contexts.
