Dozens of gallons of fire-suppressant foam were accidentally released on Thursday following an electric-component malfunction at Wright-Patterson Air Force Base, officials said.
The malfunction, which occurred in aircraft hangar 4016 on Wright-Patterson's Area A, caused the release about 100 gallons of foam, according to a press release.
Officials said the foam released is called Ansul JetX, an alcohol-based expansion foam that "cools the blaze and coats the fuel, preventing its contact with oxygen."
The foam doesn't contain perfluoroalkyl and polyfluoroalkyl substances, also known as PFAS, officials said.
PFAS are man-made chemicals commonly found in commercial products such as nonstick coatings, paints, cleaning products and fire-fighting foams, according to the U.S. Environmental Protection Agency.
PFAS in fire-fighting foams are a major source of groundwater contamination at airports and military bases, the agency says.
