Seven workers from the U.S. Centers for Disease Control and Prevention got sick while investigating the derailment of a Norfolk Southern train in Ohio earlier this year.
A team of investigators from the CDC and the Agency for Toxic Substances and Disease Registry were investigating potential chemical exposure and health effects related to the Feb. 3 derailment of the freight train in East Palestine. Several of the cars caught fire and different chemicals were released into the surrounding area.
The chemicals included vinyl chloride, butyl acrylate and ethylhexyl acrylate, according to the Environmental Protection Agency.
