Around 1,000 people were forced to evacuate their homes in Ohio after a chemical storage tank exploded, releasing a hazardous substance into the air. Authorities fear that another explosion might occur as the situation remains volatile.

The incident occurred at the MC Tank Transport facility in Toledo, at around 9:30pm Tuesday, where a tank containing glycidyl methacrylate began releasing chemicals. City officials say 983 people within a one-mile radius of the facility were evacuated, while residents within a three-mile radius were asked to stay indoors as a precautionary measure.

Toledo Mayor Wade Kapszukiewicz warned Wednesday that the chemical could remain explosive for up to 12 hours after the incident, preventing hazardous materials teams from approaching it immediately. The tank has a capacity of 5,500 gallons, posing a significant risk to the surrounding industrial area.

The chemical, commonly used in manufacturing plastics, paints and industrial coatings, can irritate the eyes, skin and respiratory system. Exposure may also cause headaches, dizziness, nausea and vomiting, prompting health officials to issue warnings to the public.

A sheriff's deputy was injured while responding to the incident and taken to hospital, although details about his condition were not immediately available. The local law enforcement agencies are coordinating with emergency responders to manage the perimeter.

Thick fog covering Toledo also created confusion among residents, some of whom mistook the weather conditions for a spreading chemical cloud. Officials cautioned that the appearance of the air could not be used to safely determine whether an area was secure.

Emergency shelters were set up for displaced residents and some local school districts cancelled classes on Wednesday to ensure the safety of students and staff. The Red Cross is assisting those who have been forced to leave their homes.

Authorities were monitoring air quality continuously and using drones to evaluate the affected area from a safe distance. The cause of the initial explosion remains under investigation by state and federal agencies.

Environmental protection teams are also on-site to assess potential soil and water contamination. Residents have been advised to follow official social media channels for real-time updates regarding the evacuation orders.

The facility management has pledged full cooperation with the investigation. As of Wednesday evening, the situation remained under close observation by the Toledo Fire and Rescue Department.
