Warning of a second blast
Mayor Wade Kapszukiewicz said the tank had "the potential within 12 hours of the incident to be explosive", so responders kept their distance. Dense fog overnight delayed drone monitoring of the site. Officials do not yet know exactly what caused the blast.
Health advice
Health department director Karim Baroudi said the chemical is "really toxic if you touch it, if you ingest it". Officials advised residents to:
- keep windows and doors closed;
- shower if they feel eye irritation or have trouble breathing;
- contact a doctor if symptoms continue;
- not call 911 about the incident unless it is an emergency.
Exposure can burn the eyes, nose, mouth and skin, and cause headache, dizziness, tiredness, nausea and vomiting. The chemical is also considered a possible long-term cancer risk.
The company
MC Tank Transport said its "immediate and overriding concern is the safety of area residents, emergency responders and our employees", and that its representatives were travelling to Toledo to work with emergency services.
Why it matters
Toledo, a city of about 265,000 on the Ohio–Michigan border, sits on major road and rail freight routes. The incident revives memories of the 2023 East Palestine train derailment in Ohio, which released toxic chemicals and raised long-running questions about industrial and transport safety.
What happens next
Crews will reassess the tank once it is safe to approach, and health officials are measuring air quality before deciding when residents can return home.
