Narrative
On february 16, 2019 dominion energy utah (deu) was notified of a house fire at 9740 bypass road, alta, utah. Deu sent a technician to the site. Upon arrival the technician was unable to access the gas meter due to excessive amounts of snow (about 12' of snow from ground level). Later, deu dispatch received an updated call from the fire department stating that a natural gas explosion may have occurred. Additional resources were sent to assist with securing the service line to the property. Company reported the incident upon discovery and suspected natural gas involvement. After the fire was contained, deu crews excavated the natural gas meter and found it was damaged. The gas service line to the unit was secured at 02:30 on february 17, 2019. A viewing of the meter and riser evidence was conducted with the involved parties and the state of utah pipeline safety on april 23, 2019. Based on information from the event investigation, deu believes that snow load, along with a snow slide from the roof of the building damaged the natural gas meter causing a leak. Leaking gas accumulated and ignited from an undetermined ignition source. This is substantiated through investigation and documented in the unified fire investigation report.
