LEXINGTON, Ky. (AP) - Authorities say a propane torch set off the blast that damaged a UPS freight hub in Kentucky's second-largest city and sent multiple people to the hospital.
Lexington fire investigator Maj. Robert King tells news outlets that the torch likely ignited leaking gas, leading to Wednesday's explosion.
Fire department spokeswoman Lt. Jessica Bowman says none of the 45 tanks of acetylene gas inside the UPS box truck at the facility actually exploded, despite initial reports. King says crews are checking the tanks to see which, if any, had leaks.
Eight people were hospitalized following the explosion. Bowman didn't have an update on victims' conditions Thursday, but all were considered in fair condition later Wednesday. King says both the propane torch operator and truck driver were among the injured.
