Narrative
48 hr. Nrc report no. 1209590 at 3:26 pm on april 15, 2018, atmos energy received a call from the arlington fire department reporting that a gas main had been struck at the intersection of ditto and dugan in arlington, tx. An atmos energy service technician arrived at 4:02 pm and determined that a gas main and a water line had been damaged during a city project to excavate the water line. The excavated trench was filling with water, and the gas line was leaking underneath the water. An atmos energy construction crew arrived at 4:20 pm to repair the gas leak and, after first confirming no gas was present in the atmosphere, began pumping water from the trench using gasoline-fired water pumps provided by the city. After some time, an accidental ignition occurred. Because this action led to the circumstance that made this a reportable incident, the cause of this incident is listed as "incorrect operations." at approximately 5:30 pm, the gas ignited over the trench damaging a backhoe that was adjacent to the trench. A flash occurred injuring a city employee and two fire fighters. The injury of one of the fire fighters resulted in hospitalization; therefore, atmos energy reported this as an incident. Atmos energy crews eliminated the gas leak at 9:40 pm and the gas main was repaired and placed back into service on april 17, 2018 at 5:00 pm.
