NTSB blames lack of training in Minneapolis school explosion

MINNEAPOLIS (AP) - Federal investigators say 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 report Monday on the explosion at Minnehaha Academy that killed two people and injured nine.

Workers for the natural gas supplier CenterPoint Energy and Master Mechanical Inc. were moving meters on Aug. 2, 2017, when the explosion happened.
