At 11 o'clock on the morning of the 20th, two wall-hung boiler sales company's commissioning staff was at Mr. Chen’s home at the Dongkeng branch of Xinqiao Farm in Jingbian County, and he conducted heating commissioning on the gas boiler installed just the day before. When debugging, the wall-hung boiler was in a no-fire condition. The commissioning staff suspected that there was air obstruction in the pipe, so the valve in the natural gas pipeline was opened to vent the air. As a result, the natural gas leaked and the flash explosion occurred suddenly when the lighter fired again.
At the time of the explosion, with the exception of two commissioning staff, Mr. Chen’s four generations of five people were injured in varying degrees, including Mr. Chen and his two-year-old grandson and his son, daughter and 74-year-old mother. After the accident, related departments started emergency rescue operations. After the wounded were briefly treated in Jingbian County Hospital, they were sent to the Second Affiliated Hospital of Yan'an University for treatment in the afternoon. As Mr. Chen, a 2-year-old grandson and 26-year-old daughter had severe skin burns, she was sent to Xi'an for further treatment yesterday morning. At present, 7 people are lifeless.
According to the investigation, the commissioning personnel opened the gas pipe network valve without authorization, resulting in leakage of natural gas of approximately 0.37 cubic meters due to improper operation. The county safety supervision bureau estimates that the leakage of 0.37 cubic meters of natural gas explosion is equivalent to that of 3 kilograms of ordinary explosives.
