Federal investigators have concluded that a deadly explosion at a Minneapolis school in 2017 happened because a pipefitting crew lacked proper training and wasn’t fully authorized to move a gas meter.
The National Transportation Safety Board released its 10-page report Monday, Dec. 2,on the explosion at Minnehaha Academy that killed two people, injured nine and caused $30 million in damage at the private Christian school’s upper campus, which overlooks the Mississippi River just south of the Lake Street-Marshall Avenue Bridge between Minneapolis and St. Paul. Workers for the natural gas supplier CenterPoint Energy and Eagan-based Master Mechanical Inc. were moving meters on Aug. 2, 2017, when the explosion happened in the basement of the school’s original century-old building.
