Damaged Gas Line Found at Site of Deadly Ohio Explosion, NTSB Says

A cut natural gas line was found in a basement area of an Ohio building which was severely damaged by a massive explosion this week, the National Transportation Safety Board reported Thursday, but it’s not yet known if that played a role in the blast. The line was not supposed to have gas in it, NTSB board member Tom Chapman said during a news conference, but it was found to be pressurized. He said the line came off the main service line and led to the building in downtown Youngstown but did not service the structure. Mr. Chapman said investigators would try to determine whether third-party work to clear out old infrastructure in the basement may have led to the line cut and explosion and why it was pressurized. Mr. Chapman said he did not believe there was anything suspicious about the cut line....
