Nitric Acid Leak Creates Plume of Smoke From Vinton County Manufacturing Plant
- On June 11, 2025, a leak released 3,000 gallons of nitric acid at Austin Powder's Red Diamond plant near McArthur, Ohio, prompting evacuations.
- The leak originated from a 5,000-gallon storage tank, and authorities enforced evacuations because nitric acid and its plume of nitric oxide are hazardous.
- Officials evacuated Zaleski village and nearby roads, directed residents to a shelter at Vinton County High School, and provided transportation for those without vehicles.
- Brad Price indicated that the gas might lead to eye discomfort and feelings of sleepiness, while Czechlewski confirmed there were no explosions or hospital admissions and noted that the National Weather Service is tracking the nitric oxide plume.
- Emergency agencies monitor air quality continuously and will lift evacuations when it is safe, suggesting the disruption could last several hours depending on gas concentrations.
