Toledo Fire & Rescue ordered evacuations and shelter-in-place orders after a chemical escaped from a tank at an industrial site in northern Toledo, releasing glycidyl methacrylate into the air. Officials warned of an explosion risk from the 5,500-gallon tank as emergency crews responded.
Emergency precautions paralyzed northern Toledo following a late-night industrial accident that sent a plume of industrial coating into the atmosphere. The incident began shortly after 9:30 p.m. on Tuesday, Oct. 20, when an employee at MC Tank Transport Inc. called 911 to report an explosion at the facility located at 1266 Progress Ave., according to Toledo Mayor Wade Kapszukiewicz. Toledo Fire & Rescue initially ordered residents within a half-mile to evacuate, but quickly widened the perimeter to a one-mile radius.
By 4:24 a.m. Wednesday, Oct. 21, safety officials expanded precautions further, issuing a shelter-in-place order for everyone living or working within a three-mile radius of the site. Neighborhoods including Raintree Village and Alexis Addition fell directly inside the evacuation zone. The American Red Cross and TARTA buses established temporary staging at the Meijer parking lot off East Alexis Road, while Shoreland Elementary School opened as a temporary shelter for displaced families.
Explosion Risks Delay Hazmat Teams at MC Tank Terminal
First responders faced severe hazards that kept emergency crews from immediately approaching the damaged container. Mayor Kapszukiewicz explained during a morning news briefing that the tank, which had a capacity of 5,500 gallons, remained highly volatile hours after the initial rupture.
There is still concern that the tank is emitting this chemical and it has the potential within 12 hours of the incident to be explosive.

Because of that ongoing risk, hazardous materials teams and firefighters could not approach the equipment until at least 9:30 a.m. Wednesday, waiting for the 12-hour window of instability to subside. MC Tank Transport Inc., a subsidiary of The Kenan Advantage Group, confirmed in a statement that equipment linked to its operations was involved in the hazardous materials leak. City officials noted that one first responder sustained injuries during the initial response and drove himself to the hospital, though authorities believe the injury is not serious.

Glycidyl Methacrylate Exposure and Public Health Warnings
The substance released into the air is glycidyl methacrylate, commonly known as GMA, an industrial chemical used to improve the performance of plastics, paints, and coatings. City and health officials moved quickly to inform the public about its toxicological profile while urging calm across the community.
It’s really toxic if you touch it, if you ingest it.

Baroudi added that while the chemical is a long-term carcinogen, there was no immediate danger of cancer resulting from the nighttime release. In liquid form inside storage containers, the substance converts into a gas when exposed to the air. Contact with the chemical can produce burning sensations in the eyes, nose, mouth, and skin, alongside symptoms like headaches, dizziness, fatigue, nausea, and vomiting. The Toledo-Lucas County Health Department published an informational fact sheet to guide residents experiencing minor irritation to shower and rinse affected areas while seeking medical help for serious respiratory distress.

Dense Fog Compounds Confusion as Agencies Coordinate Response
Thick morning fog blanketed northern Toledo just as the emergency unfolded, creating widespread confusion among residents who mistook natural weather haze for the chemical plume. The National Weather Service tracked the fog, which temporarily grounded drone surveillance operations intended to assess the leak from above. City officials repeatedly emphasized that visibility was hindered by weather rather than the industrial release.
Coordinated multi-agency response efforts drew praise from Lucas County Commissioner Lisa Sobecki, who noted that emergency protocols benefited directly from years of prior cross-training exercises. Environmental Protection Agency personnel joined local firefighters and county emergency managers on site as specialized resources arrived to contain the leak and clear the area for safe reentry.
