An investigation by the National Transportation Safety Board revealed that a crew working in the basement area of a building in Youngstown, Ohio, intentionally cut a pressurized gas line, leading to a deadly explosion. The incident occurred as workers were clearing out piping and outdated infrastructure in preparation for a city project to fill in the area and replace sidewalks.
According to the NTSB, workers were unaware that the gas line was pressurized and only realized the issue after making the third cut. Following this discovery, they promptly pulled the fire alarm and evacuated residents and bank employees. The explosion occurred six minutes later, resulting in significant damage to the building.
