A 5,500-gallon (about 20,800-liter) chemical storage tank ruptured in Toledo,
Ohio, on the evening of the 20th, releasing glycidyl methacrylate vapor. Nearly
1,000 residents were evacuated and authorities advised more than 50,000 to
shelter indoors; at least 35 people were treated in hospital for eye or throat
irritation and local schools were closed. Mayor Wade Kapszukiewicz said the leak
resulted from a transfer error and officials are allowing the tank to vent
naturally to avoid triggering an explosion.
