Synopsis

At approximately 1724 on 28 December 2000, a release of natural gas resulted in an explosion that destroyed the electrical and services building, heavily damaged the compressor building, and damaged the remaining buildings at the East Hereford compressor station (Kilometre Post 217,094) on Line 3000 of Gazoduc TQM Inc. Before the occurrence, the station had been shut down since approximately 1004 due to an unintentional manual initiation of the station's emergency shutdown system. Following the emergency shutdown of the compressor station, a maintenance person was sent to the station to reinitiate the electric motor-driven compressor unit. During the day, after repeatedly trying to get the station into the ready state mode to return the station to normal pipeline operations, an explosion occurred. The on-site maintenance person was seriously injured.
