A tanker truck leaking hydrochloric acid sent two people to the hospital and forced an overnight evacuation in Barberton, with fire crews rushing to the 700 block of Norton Avenue just after 11 p.m. Monday. Cleanup and mitigation efforts were still underway as of 8:28 a.m. Tuesday, according to a city update.
Barberton fire crews were dispatched to the scene at approximately 11:03 p.m. Monday, as reported by WKYC. Upon arrival, they determined that the tanker truck was leaking hydrochloric acid. The affected area was evacuated and secured.
Hazmat and EPA Called In Overnight
City officials said the Summit County hazmat team and the Ohio EPA were both contacted to respond to the scene, per the same city post relayed by the station. That county hazmat unit operates under the Summit County Special Operations Response Team Executive Board and the Summit County Emergency Management Agency, which carries out its mandate under Chapter 5502 of the Ohio Revised Code, according to Summit County, Ohio. The agency's emergency response operations extend across 31 political subdivisions countywide.
The team is also certified by the state as a Type I hazardous materials response unit, meaning it is equipped to handle high-level chemical emergencies not just in Summit County but across Ohio Region 5 and, in some cases, nationally, according to Nordonia Hills News. Grants fund specialized training and are financed by fines paid by hazardous-material carriers and shippers. Notably, county emergency management personnel had run a full-scale exercise simulating a leaking chemical tanker rail car in July 2025, according to Akron.com, a drill built around multi-agency unified command protocols for exactly this kind of release.
What Hydrochloric Acid Exposure Can Do
Hydrochloric acid is federally classified as a Class 8 corrosive material under identification number UN1789, according to the U.S. Pipeline and Hazardous Materials Safety Administration, a designation that governs how it must be shipped, placarded, and handled in transit. Under federal Superfund rules, releases of the chemical at or above 5,000 pounds require immediate notification to the National Response Center, per Alliance Chemical.
Exposure to hydrochloric acid vapors or hydrogen chloride gas can cause irritation, corrosive damage, and pulmonary edema. Workplace safety regulators enforce a 5 parts-per-million ceiling limit for hydrogen chloride gas, while NIOSH sets the threshold considered immediately dangerous to life or health at 50 ppm, per the CDC.
A City With Recent Industrial Incident History
Barberton has dealt with industrial chemical scares before. In July 2023, Barberton had an oil spill involving a tanker truck and railcar; the city later released a video, Akron.com reported. And in March 2024, municipal officials responded to a wastewater leak at PPG Industries after the company reported a pipe on its property was leaching wastewater into the ground, the outlet reported.
Under Ohio law, chemical spills that exceed reportable quantities and leave facility property must be verbally reported to local fire departments, the county emergency planning committee, and the Ohio EPA within 30 minutes of discovery, per state rules cited by Summit County's Local Emergency Planning Committee. Whether the Norton Avenue leak breached the tanker's immediate footprint, how much acid was released, or what specifically caused the leak were not addressed in the city's update.
The City of Barberton thanked the Summit County hazmat team, the Ohio EPA, and the Barberton police and street departments for their work responding to the spill. As of Tuesday morning, cleanup and mitigation efforts remained ongoing.
