Toledo Chemical Leak: Evacuation in 1 Mile, Shelter in 3

Updated 00:18 UTC, Oct 22, 2026: Shelter in place lifted, evacuation cut to half a mile

Toledo Fire and Rescue lifted the three mile shelter in place order at 5 p.m. local time on Wednesday, Oct. 21, and cut the evacuation zone around the MC Tank Terminal at 1266 Progress Ave. to a half mile, the city said in an update posted at 6:36 p.m. local time. The release of glycidyl methacrylate is still ongoing, and hazardous materials crews are working with federal, state and local partners to monitor conditions and decide next steps, the city said. Mayor Wade Kapszukiewicz told reporters on Wednesday afternoon that crews were waiting for the tank to finish venting rather than trying to stop the leak directly, because the threat to the public was low and an intervention carried more risk. He said the tank temperature was falling and the amount of gas being vented was significantly lower. USA Today reported that local hospitals had treated 35 people. Air monitoring had not shown significant concerns for human health, the Akron Beacon Journal reported, though people with asthma or breathing sensitivities could face minor irritation.

Updated 21:34 UTC, Oct 21, 2026: About 30 people treated in hospitals

About 30 people went to local hospitals with symptoms that may be related to the chemical leak, and most were treated and released, ProMedica said in a statement reported by USA Today. The health system gave the count as of 2 p.m. local time on Wednesday, Oct. 21. That is a wider count than the single injury reported earlier in the day, the Lucas County sheriff's deputy who drove himself to a hospital. City spokesperson Rachel Hart said the release had not finished at the 12 hour mark officials had expected, so crews could not move in as quickly as hoped. The tank temperature was falling and the release had slowed significantly, Hart said, but the one mile evacuation order and the three mile shelter in place order remain in effect.

Updated 18:35 UTC, Oct 21, 2026: Reaction could run 6 to 16 more hours

The chemical reaction inside the damaged tank at the MC Tank Terminal could take another six to 16 hours to finish, officials said at a 1 p.m. news conference, the Akron Beacon Journal reported. The US Environmental Protection Agency said on Wednesday afternoon that the release is ongoing, that fire department attempts to contain it were not successful, and that the city has decided the safest course is to let the reaction complete on its own. The tank held 5,500 gallons of glycidyl methacrylate, a flammable chemical that was being transferred when an error occurred, the Ohio EPA said. The only known injury remains the Lucas County sheriff's deputy who drove himself to a hospital. The one mile evacuation zone, covering about 983 people, and the three mile shelter in place order stay in effect.

Updated 16:33 UTC, Oct 21, 2026: City says no explosion, 983 people evacuated

The city of Toledo now says no explosion occurred. City spokesperson Rachel Hart told USA Today that there was a release of glycidyl methacrylate from a tanker that produced a large plume. That clarification follows Mayor Wade Kapszukiewicz calling the incident an explosion of the chemical tank at his Wednesday news conference, a description other national reports also used.

About 983 people live inside the one mile evacuation zone around the MC Tank Terminal at 1266 Progress Avenue, officials said. The tank can hold 5,500 gallons of the chemical, which is a liquid inside the tank and becomes a gas when released. The injured Lucas County sheriff's deputy drove himself to a hospital, the mayor said.

Lucas County health commissioner Karim Baroudi said the chemical is mostly an irritant at this point, and that smelling it or feeling irritation does not by itself mean a person is being exposed to dangerous levels. No new city update had been released as of 10:30 a.m. local time, after the 12 hour window of possible explosive risk that the mayor placed at about 9:30 a.m. had passed, the Akron Beacon Journal reported. The evacuation and shelter in place orders remained in place on Wednesday morning.

The three mile shelter in place zone also reaches across the state line into Monroe County, Michigan. Bedford Public Schools, Mason Consolidated Schools and the Whitman campus of Monroe County Community College closed for Wednesday, Oct. 21, and the shelter order covers the Erie and Temperance areas of Monroe County, the Monroe News reported.

Air monitoring is under way with help from the US Environmental Protection Agency, The Sun Times News reported. Dense fog cut visibility and delayed the use of drones to watch the site, the mayor said, in a city of about 265,000 people. Arkansas based MC Tank Transport said it is working with the fire department and other emergency authorities and called the safety of residents, responders and employees its overriding concern, the AP reported. Officials had not determined whether the deputy's symptoms were related to the chemical exposure, The Sun Times News reported.

Updated 13:06 UTC, Oct 21, 2026: Chemical named, deputy injured

Officials have now named the chemical released in north Toledo as glycidyl methacrylate. City officials and MC Tank Inc., the company whose equipment was involved, identified the chemical, which is used in plastic coatings. Officials said at a Wednesday news conference that it is a carcinogen if ingested at certain levels, and that exposure can cause itching in the eyes and throat.

One person has been injured, a sheriff's deputy who was taken to a hospital. It is the only injury reported so far, which corrects the earlier city statement carried below that no injuries had been reported. Mayor Wade Kapszukiewicz told the news conference that the tank was still emitting the chemical and could stay explosive within 12 hours of the incident, so hazmat crews had not approached it and would reassess at about 9:30 a.m. local time, USA Today reported. The evacuation and shelter in place orders remain in effect. The original report follows.

Toledo Fire and Rescue has ordered everyone within one mile of the MC Tank Terminal at 1266 Progress Avenue in north Toledo to evacuate after a hazardous materials release that began at 10:48 p.m. on Tuesday, Oct. 20. Everyone within three miles must shelter in place. The release is still going on, the city said in an update posted at 7:30 a.m. on Wednesday, Oct. 21.

What residents are told to do

Shelter in place means stay indoors, close all windows and doors, and turn off ventilation that draws in outside air. Keep pets indoors, the city said. The shelter in place order was added at 4:24 a.m. on Wednesday. The evacuation zone was first set at half a mile on Tuesday night and then widened to one mile.

The city has not named the chemical. It described the release as an irritant that can burn the eyes, nose, mouth and skin, and said there has been no explosion, only a release. News crews in the area reported a haze and a chemical smell. City officials warned that dense fog over Toledo on Wednesday morning cannot be told apart from the release by sight.

Where to go, and what is closed

People leaving the evacuation zone can go to Shoreland Elementary School, which is open as a temporary shelter, or to the Meijer parking lot off East Alexis Road, where the Red Cross and TARTA buses are stationed. The neighborhoods inside the zone include the Raintree Village mobile home park and the Alexis Addition, and township officials helped evacuate Raintree Village residents.

Toledo Public Schools and Washington Local Schools both cancelled classes for Wednesday, Oct. 21. Enterprise Boulevard is closed between Stickney Avenue and Benore Road, and rail operations near the terminal were halted. No injuries or deaths have been reported, the city said. Residents with health questions can call the Toledo-Lucas County Health Department at 419-213-4100.

What is not known yet

Fire department spokesman Pvt. Sheldon Collins told local reporters early Wednesday that a tank on the ground outside the facility was leaking. The cause is under investigation, and officials have not said when the orders will be lifted. City officials held a news conference at 7:30 a.m. on Wednesday and said the city page will be updated as new information comes in.
