A tank carrying glycidyl methacrylate ruptured in an industrial area of Toledo, Ohio, sending a plume into the air and prompting evacuations within a one-mile radius and shelter-in-place guidance for a wider area. Officials said they were allowing the tank to vent because approaching it could expose responders to danger, while air testing continued.

A ruptured tank containing glycidyl methacrylate continued releasing a white plume in Toledo, Ohio, on Wednesday, prompting evacuations and shelter-in-place guidance as city officials said they were letting the chemical vent rather than sending responders close to a potentially unstable tank. The decision affects residents near the industrial site and has disrupted schools and production at a nearby Jeep plant.

Nearly 1,000 residents within a one-mile radius were told to evacuate overnight, while more than 50,000 people within a three-mile radius were advised to stay indoors. The shelter area includes neighborhoods along Lake Erie and reaches across the state line into Michigan. Schools across Toledo were closed Wednesday, and Stellantis halted production at its nearby Jeep assembly plant.

The tank began leaking Tuesday night, and video showed the plume continuing into early Wednesday afternoon, more than 14 hours later. Mayor Wade Kapszukiewicz said officials chose to let the release continue because approaching the tank could be more dangerous, particularly with other tanks stored at the chemical trucking company’s facility. He said drones showed the tank’s temperature falling and the plume diminishing, but it could still take hours before the tank was safe to approach.

MC Tank Transport said the tank held glycidyl methacrylate, which the company described as an industrial chemical used in making some plastics, paints and coatings. The Ohio Environmental Protection Agency said the leak followed an error during transfer of the material. Officials said reported symptoms included eye and throat irritation. One responding sheriff’s deputy later drove himself to a hospital after feeling unwell, according to city officials. Testing was underway to measure the chemical’s concentration in the air and assess possible health risks.

The developmentToledo officials are allowing a ruptured chemical tank to vent while residents evacuate or shelter indoors and crews monitor the plume.

Evacuation Orders Disrupt Toledo

The incident has affected residents across a broad area, with different instructions depending on proximity to the site: evacuate within one mile and shelter indoors within three miles. The orders, school closures and factory shutdown show the immediate reach of the emergency beyond the industrial facility itself.

Officials’ choice to let the tank vent reflects a trade-off between limiting the release and protecting responders from the risk of another explosion. The potential health effects also remain under review: the reported irritation is confirmed by officials, but air testing is needed before they can provide more specific guidance about exposure beyond the immediate symptoms.

How the Response Unfolded

The rupture occurred Tuesday night at a facility in an industrial area of Toledo. Mayor Kapszukiewicz said officials initially worried that the tank, which can hold 5,500 gallons, might explode. Emergency and hazardous-material crews were not approaching it because of that risk, he said.

The city coordinated with state and federal environmental officials as the plume continued. MC Tank Transport said it was working with the fire department and other emergency authorities, and the mayor said company representatives were on their way to Toledo. The Ohio EPA attributed the leak to an error during transfer but did not provide further details in the report.

“There’s no question the situation is improving.”

— Toledo Mayor Wade Kapszukiewicz

Air Test Results Are Pending

Officials had not released air-test results showing the concentration of glycidyl methacrylate or whether levels posed additional health risks. The extent of any exposure outside the reported irritation symptoms, including possible effects from material settling on homes, vehicles or gardens, was not established in the report.

The precise cause of the transfer error, the amount of chemical released and the tank’s condition remained unclear. Although the mayor said monitoring indicated improvement, officials had not said when responders could safely approach or when evacuation and shelter orders might be lifted.

Monitoring Before Crews Approach

City, state and federal officials were continuing to monitor the tank and test the air. Kapszukiewicz said the tank’s temperature and plume were being tracked by drone, and that it could take hours before responders could approach safely. Residents should follow current local instructions while authorities assess conditions.

The next public guidance will depend on monitoring and test results, including whether the plume continues to diminish and whether air measurements support changing the protective orders. The source report did not give a timetable for lifting restrictions, reopening schools or restarting production at the Jeep plant.
