Narrative
On wednesday, july 7, 2021, at approximately 9:30 am a general fitter (gf) was excavating a 3/4-inch steel gas service line in a customer's lawn to complete a service renewal. During the course of the work activities, the 3/4-inch steel gas service line was broken at the 3/4-inch outlet of the service tee, and a 240 volt energized electric cable supplying street lamps was severed. It is believed that the severed electrical cables served as an ignition source, igniting the gas within the excavation. During the resulting fire, the gf suffered injuries to the extent that ems responded and transported the employee to the hospital for treatment. The root cause is that general fitter and fitter failed to follow the procedure and have separated from the company. Specifically, failure to follow distribution & transmission procedure(d&tp) 1.1 "preventing accidental ignition", d&tp1.6 "energy gas excavation and confined space entry," and d&tp 4.6 "identifying and protecting underground utilities, conduits, and structures."
