Pittsburgh Police from Zone 4 responded to a call for possible explosive material discovered in the 5600 block of Cox Avenue just before 8 p.m. on May 21.
Responding officers spoke with a resident who had purchased an old military medical kit with gauze that contained picric acid, which was once used as an antiseptic. Picric acid can become unstable when it's bumped or heated up quickly.
The homeowner took it outside and the Bomb Squad was called in. They determined the material shouldn't be transported and opted to dispose of it on site. Pittsburgh Bureau of Fire and EMS were standing by.
After establishing a perimeter and ensuring no one was on their front porches or yards, the technicians dug a hole in the ground and safely disposed of the material.
There were no injuries or resulting property damage and the hole was later filled in.
Tonight, the City-County Building is illuminated to recognize Poison Prevention Week and the 50th Anniversary of "Mr. Yuk" in partnership with Children's Hospital of Pittsburgh of UPMC.
For questions about the lighting at the City-County Building, please reach out to the Office of the Mayor.
