Incident overview

During a fireplace service in a row house, an energized 120V wire contacted a copper gas line, creating an arc and melting the gas line. The damaged gas line caused uncontrolled release of gas and ignition until the technician extinguished it. Further investigation saw a damaged factory crimp in the wiring with the uninsulated conductor exposed. The open conductor may have been due to manufacturer defect or field damage.
