Toledo hazmat incident in Ohio: What is glycidyl methacrylate chemical and how does it impact? Check symptoms
Ohio fire department said symptoms of overexposure include headache, dizziness, tiredness, nausea and vomiting. It advised residents to contact a medical professional if they believe they are having a reaction to exposure.

People within a 1.6-kilometer radius of the “hazardous materials release” were ordered to evacuate at about 10:50 p.m. Tuesday. The shelter-in-place order was issued for Toledo residents within a 4.8-kilometer radius beyond that area. Dense fog and haze hindered visibility in the city of about 265,000 people, and local news stations reported smelling a plastic-like odor.
The evacuation order was in relation to an address on Progress Avenue, an industrial and commercial area in the north part of the city. The release is ongoing, and crews continue to monitor the situation, the Toledo Fire & Rescue Department said in a statement posted online early on Wednesday.
The department did not name a business, but MC Tank Transport Inc., which is located on that street, said in a statement Wednesday that “equipment associated with our operations is involved in the hazardous materials incident.”
MC Tank said the chemical involved is glycidyl methacrylate, which it described as “an industrial chemical used to make certain plastics, paints and coatings perform better.”
The company, which handles the transportation of liquid chemicals, said: “Our immediate and overriding concern is the safety of area residents, emergency responders and our employees.”
It said it is working with the fire department and other emergency authorities. “We have mobilized additional specialized emergency response resources to assist,” it said in the statement.
The fire department said symptoms of overexposure include headache, dizziness, tiredness, nausea and vomiting. It advised residents to contact a medical professional if they believe they are having a reaction to exposure.
“You can't tell fog from the release by looking, so please don't rely on how the air looks,” the department said in the news release. “If you are outside the evacuation or shelter-in-place zones and smell an unusual odor, please stay indoors, close windows and doors and turn off ventilation that draws in outside air.”
