A chemical tank explosion on Tuesday, Oct. 21 released a hazardous chemical in northern Toledo, Ohio, prompting an evacuation order for residents within a 1-mile radius of the explosion and a shelter-in-place order for residents within a 3-mile radius.

The tank was carrying 5,500 gallons of glycidyl methacrylate.

Here’s what we know about the chemical.

What is glycidyl methacrylate?

Glycidyl methacrylate (GMA) is a laboratory chemical that can be used in adhesives, automotive and industrial coatings, and latex. It can be used in epoxies and other building materials.

More on GMA:

  • It is acutely toxic if swallowed or inhaled. 
  • It is corrosive and irritating to the skin and eyes.
  • Based on animal studies, it may also be mutagenic, carcinogenic and toxic to reproduction.
  • It may also be dangerous to aquatic life and environments.
An evacuation order has been issued for residents within a one-mile radius of 1050 Progress Ave. in Toledo, Ohio, following a "hazardous materials release." Residents within a three-mile radius are being asked to shelter-in-place.
