Dozens Treated After Toledo Chemical Release
Toledo Mayor Wade Kapszukiewicz attributed the release at MC Tank Terminal to employee error, the Associated Press reported October 23. He said a worker “introduced a temperature level to the tank” during liquid transfer, triggering a reaction. The company accepted responsibility, he said, but the investigation continued. He reported no fire or explosion. AP said 57 people received hospital treatment.
Chemical Release Prompts Emergency Response
According to the U.S. Environmental Protection Agency’s incident record, Toledo Fire and Rescue responded around 10 p.m. October 20 to a release of glycidyl methacrylate from an approximately 5,500-gallon intermodal tank near 1266 Progress Ave.
EPA personnel arrived at 2:30 a.m. October 21 to provide technical assistance, including air modeling to support evacuation decisions. The agency subsequently monitored volatile organic compounds and particulates around the evacuation perimeter and collected air samples.
In its October 21 morning update, EPA said the tank had been compromised and the chemical inside was undergoing a reaction. Attempts to contain the release had been unsuccessful, and the city determined that allowing the reaction to finish was the safest course. EPA continued supporting the fire department with technical assistance and expanded air sampling.
Evacuation Orders Lifted
Toledo initially ordered residents within one mile of the terminal to evacuate late October 20. Officials added a three-mile shelter-in-place order early October 21, according to the city’s incident timeline.
The city lifted the shelter-in-place order October 21 and reduced the evacuation area to a half-mile radius. The evacuation zone narrowed to a quarter-mile October 22 before officials lifted the remaining order at noon October 23.
Hazardous-materials crews found no detectable hazards during re-entry, the city said. Officials determined that conditions allowed the facility to be turned over to the company and EPA for the next phase of cleanup. The Toledo-Lucas County Health Department also issued guidance for residents returning to their homes.
Coatings Raw Material Connection
Glycidyl methacrylate has applications in coating compounds and polymer materials. Manufacturer technical information for the chemical lists coating compounds, antistatic additives and ion-exchange resins among its uses. It also identifies heat and sunlight as conditions under which the material can polymerize. These are general material properties, not findings from the Toledo investigation.
The incident is relevant to manufacturers and suppliers handling monomers used in paint and coating resins and polymers, particularly emergency planning and coordination across chemical-storage and transportation operations.
