Toledo Chemical Tank Incident: Leak of Glycidyl Methacrylate Triggers Evacuation and Shelter-in-Place Orders
By Drooid · · How we work
Core Event
Late Tuesday night, a 5,500-gallon tank at MC Tank Transport Inc.’s facility on Progress Avenue ruptured, releasing glycidyl methacrylate (GMA) into the air. The dense white plume prompted Toledo Fire & Rescue to evacuate residents within a one-mile radius and issue a shelter-in-place order for those out to three miles. As the tank’s temperature and pressure fell, officials reduced the evacuation perimeter to a half-mile and later to a quarter-mile, lifting the shelter-in-place directive.
Background & Context
MC Tank Transport Inc., a subsidiary of Kenan Advantage Group, transports bulk liquids and ISO containers. GMA is used in plastics, paints and coatings. State and federal agencies said the leak resulted from an error during material transfer; the precise cause remains undetermined. A similar regional incident occurred in 2023 with a sulfuric-acid spill into the Ottawa River.
Data & Statistics
- About 57 patients received treatment for exposure-related symptoms; seven remained in care, none in serious condition.
- The initial evacuation affected roughly 1,000 residents; the current quarter-mile zone contains 54 households.
- Most patients presented with respiratory irritation; some reported headache, dizziness, nausea or vomiting.
- EPA air monitoring showed decreasing GMA concentrations as the tank cooled.
Official Statements & Responses
City officials emphasized an “abundance of caution.” Mayor Wade Kapszukiewicz said venting the tank was chosen because the immediate threat to the public was low and active intervention could trigger an explosion. The fire department noted crews could not approach the tank while material remained inside. The Ohio EPA confirmed the leak stemmed from a transfer error and classified GMA as flammable with a noticeable odor. MC Tank Transport pledged cooperation with authorities and stressed resident safety.
On-the-Ground Reports
Local hospitals treated most patients with breathing treatments and observation. A sheriff’s deputy self-transported to a hospital for evaluation. Temporary shelters were set up at Shoreland Elementary School and a Meijer parking lot, with Red Cross assistance. Residents reported eye and throat irritation, a plastic-like odor, and occasional lingering taste. Guidance advised those outside the evacuation zone to keep windows closed, turn off outdoor ventilation, and use recirculation mode while driving.
Conflicting Reports & Gaps
Sources differ on whether an explosion occurred. Early statements from the mayor referenced an “explosion,” but a city spokesperson later clarified none was confirmed. Evacuation figures also vary, with reports ranging from 300 to about 1,000 displaced residents. The cause of the breach remains identified only as a transfer error, and no definitive assessment of long-term environmental impact has been released.
Verbatim Quotes
- “There is a difference, though, between an annoying or unpleasant taste in your mouth or smell, and a dangerous or toxic amount of exposure. There is no question that we're all kind of smelling and sensing something in the air. That doesn't necessarily mean that it is something that is harming us immediately. There are levels of exposure to something like this,” — Wade Kapszukiewicz, Toledo mayor
- “The release has been confirmed as Glycidyl Methacrylate, which is classified as flammable and has a noticeable odor. It came from a 5,500-gallon tank because of an error that occurred when the material was being transferred,” — Bryant Somerville, Ohio EPA spokesperson
