Ohio Chemical Tank Blast Spurs Evacuations After Days of Leaks
WHO:
CBS News - Toledo Mayor Wade Kapszukiewicz said the tank’s potential to explode made it too dangerous for first responders, including hazardous-material teams, to approach.
PBS - A sheriff’s deputy was injured while responding to the explosion and drove himself to a hospital, Mayor Wade Kapszukiewicz said. The mayor did not provide the deputy’s name.
CBS News - Toledo resident Travis Williams said he woke up choking and experienced burning, itchy skin, and irritated eyes. He said he was worried about long-term effects.
PBS - Karim Baroudi, director of the Toledo-Lucas County Health Department, said officials were assessing the air’s toxicity and described the chemical as “really toxic if you touch it, if you ingest it.”
PBS - Arkansas-based MC Tank Transport said it was working with the fire department and other emergency authorities; company representatives were traveling to Toledo.
WHAT:
CBS News - The chemical plume remained after the shelter-in-place order was lifted and the evacuation area reduced.
CBS News - Residents described the scene as “looked like a movie”; Travis Williams said, “I couldn't even see as far as my car to the curb.”
CBS News - In May, a tank containing another methacrylate compound ruptured in Orange County, California, displacing thousands; a crack formed in the overheating tank, relieving pressure and ending the explosion risk.
PBS - Mayor Wade Kapszukiewicz said the tank could remain explosive within 12 hours of the incident.
PBS - The Toledo Fire Department advised people experiencing symptoms to contact a medical professional.
PBS - Karim Baroudi advised residents to close their windows and said those experiencing eye irritation or heavy breathing should shower.

PBS - A chemical tank containing glycidyl methacrylate exploded, prompting evacuations and shelter-in-place orders. The mayor said the tank could still be explosive and that officials did not know what caused the explosion.
CBS News - The tank held 5,500 gallons. Officials allowed the chemical to vent rather than send crews to stop the leak.
CBS News - One first responder was injured; a hospital was treating 35 patients. Residents reported burning eyes, lungs and sinuses, headaches, and nausea.
PBS - Glycidyl methacrylate can cause burning eyes, nose, mouth, and skin; overexposure may cause headache, dizziness, tiredness, nausea, and vomiting.

WHERE:
CBS News - The leak occurred at an MC Tank facility in Toledo, Ohio.
PBS - More than 900 people lived within the one-mile evacuation zone; the mayor said all were believed to have left. Residents within a three-mile (4.8-kilometer) radius were ordered to shelter in place.
PBS - Toledo has about 265,000 residents.
WHEN:
PBS - The deputy responded at around 9:30 p.m. Tuesday. The mayor addressed the incident Wednesday morning.
WHY:
CBS News - State officials said the leak resulted from an error while the chemical was being transferred.
PBS - Authorities kept responders away from the tank because of the risk of further explosions.
HOW:
PBS - First responders, hazardous-material and safety teams planned to reassess conditions later in the morning before approaching the tank.
CBS News - The city initially ordered evacuation within one mile and sheltering within three miles; Wednesday, it lifted the shelter order and reduced the evacuation area to half a mile.

A chemical tank exploded at an MC Tank facility in Toledo, Ohio, releasing a toxic plume and forcing hundreds of people from their homes. The 5,500-gallon tank held glycidyl methacrylate, which can become a gas when released. Officials said a transfer error caused the leak, but the explosion’s cause remains unknown. Because the tank could explode again, crews stayed back and allowed the chemical to vent. More than 900 people were believed to have left the one-mile evacuation zone, while residents within three miles were initially told to shelter in place. A sheriff’s deputy was injured, and a hospital was treating 35 patients. Residents reported burning eyes and skin, headaches and nausea. The city later lifted the shelter order and reduced the evacuation area to half a mile. The EPA monitored air quality as officials assessed the risk.
