A tank containing glycidyl methacrylate leaked and released a plume in Toledo, Ohio, prompting nearly 1,000 people to evacuate and more than 50,000 to shelter indoors. City officials said they were allowing the tank to vent because approaching it could raise the risk of another explosion; air testing was underway to assess exposure.
A leaking chemical tank in Toledo, Ohio, continued releasing a white plume Wednesday after an explosion, prompting nearly 1,000 residents to evacuate and more than 50,000 people to shelter indoors. Mayor Wade Kapszukiewicz said city leaders were allowing the tank to vent because sending emergency crews near it could be more dangerous and risk another explosion.
The leak began Tuesday night at a chemical trucking company’s industrial-area facility. Videos showed a plume still rising from the tank early Wednesday afternoon, more than 14 hours after the leak began. The tank can hold up to 5,500 gallons, according to Kapszukiewicz. He said drones monitoring it showed its temperature was falling and the plume was diminishing, but it could take hours before the tank was safe to approach.
MC Tank Transport said the tank contained glycidyl methacrylate, describing it as an industrial chemical used to improve the performance of certain plastics, paints and coatings. The Ohio Environmental Protection Agency said the leak resulted from an error during the transfer of the material, without providing further details. Officials had not publicly explained the cause of the explosion.
An evacuation covered a one-mile radius around the site. A shelter-in-place order applied to more than 50,000 people within a three-mile radius, including neighborhoods near Lake Erie and an area just over the Michigan state line. Toledo schools closed Wednesday, and Stellantis halted production at its nearby Jeep assembly plant.
Evacuations Disrupt Toledo Area
The incident has affected residents well beyond the immediate industrial site. People within the evacuation zone had to leave their homes, while the broader shelter-in-place order reached tens of thousands of residents. School closures and the shutdown at the nearby Jeep plant show how the response has disrupted everyday life and local business operations.
There is also a public-health concern, but the extent of any exposure was not yet established. City officials said some people reported eye and throat irritation. A responding sheriff’s deputy later drove himself to a hospital after feeling unwell, according to city officials. Officials were testing air samples to determine chemical concentrations and whether the plume posed additional health risks.
The decision to let the chemical escape rather than approach the tank reflects a trade-off officials described between controlling the release and protecting responders from a possible explosion. The effects on people, property and the surrounding environment remained under assessment.

Why Officials Let the Tank Vent
City leaders said the tank was still considered dangerous to approach because of the risk of another explosion and the presence of additional tanks at the trucking facility. Kapszukiewicz said officials judged that sending first responders closer could be more hazardous than allowing the material to vent while they monitored conditions.
The chemical is liquid inside the tank but becomes a gas when released, the mayor said. The city fire department warned that contact with glycidyl methacrylate can cause burning sensations in the eyes, nose, mouth and skin; it also listed headaches, dizziness, tiredness, nausea and vomiting as possible effects of overexposure. Those warnings describe possible effects, not confirmed diagnoses among residents.
Health officials advised people to close their windows. Toledo-Lucas County Health Department director Karim Baroudi said people experiencing irritation or difficulty breathing should take a shower for now, and the fire department advised people with symptoms to contact a medical professional. The city said odors reported outside the shelter zone did not by themselves establish that the air was harmful.
“There’s no question the situation is improving.”
— Toledo Mayor Wade Kapszukiewicz
Air Test Results Still Pending
Officials had not released the results of testing to establish the chemical’s concentration in the air or whether the measured levels posed additional health risks. The duration and full extent of the release were also not known, and officials had not said when the tank would be safe to approach.
It remained unclear how much chemical, if any, reached homes, vehicles, gardens or other surfaces during the overnight rain. Residents outside the affected zone reported chemical or paint-like odors, but an odor alone does not establish the level of exposure. Authorities had not reported confirmed long-term health effects.
The Ohio EPA attributed the leak to an error during material transfer but gave no account of how the error occurred. The precise cause of the explosion, the amount released and the length of the cleanup were not specified in the report.
Monitoring Before Crews Approach
Emergency and hazardous-material teams were expected to continue monitoring the tank and the surrounding air while keeping personnel away from the immediate danger area. City officials said drones showed improving conditions, but the tank would remain off-limits until responders judged it safe to approach.
Air-testing results are expected to help officials refine guidance for residents and determine whether the shelter-in-place order can be changed. People in the affected areas should follow instructions from local authorities; the fire department advised anyone experiencing symptoms to contact a medical professional.
Further updates are also needed on the cause of the transfer error, the amount of chemical released and any assessment of impacts to nearby properties or the environment. The company said it was cooperating with emergency authorities, but a timetable for ending the response had not been provided.
Key Questions
What chemical was in the tank?
MC Tank Transport said it was glycidyl methacrylate, an industrial chemical used in certain plastics, paints and coatings.
Who was told to evacuate or stay indoors?
Nearly 1,000 people within a one-mile radius were told to evacuate. A shelter-in-place order covered more than 50,000 people within three miles, including an area across the Michigan state line.
Why did officials allow the tank to keep venting?
Mayor Wade Kapszukiewicz said approaching the tank could expose responders to danger and increase the risk of another explosion. Officials chose to monitor the release rather than send crews close to the tank while it remained unsafe.
Is the air safe to breathe?
Officials had not released air-test results establishing chemical concentrations or the level of risk. Residents were told to follow local instructions, close windows and seek medical advice if they developed symptoms.
When will the evacuation and shelter orders end?
No end time had been announced. The mayor said it could take hours before the tank was safe to approach, and officials were continuing to monitor the tank and test the air.
