while investigating danger zone

The Centers for Disease Control and Prevention (CDC) team studying the health impacts of the Ohio train derailment fell ill themselves during the investigation.

Seven of the team suffered sore throats, headaches, coughing and nausea in early March — the same symptoms experienced by residents following the train derailment on February 3, which released a toxic soup of chemicals into East Palestine and beyond.

The government investigators were carrying out door-to-door surveys in the area to determine the effects on residents' health.
