Natural gas flash explosion accident
On September 2, when the kitchen staff of Beijing Defuxiang Catering Management Co., Ltd. was cooking breakfast, the gas cylinder in the kitchen suddenly exploded, causing a direct economic loss of about 9200 yuan.
After investigation, the cause of the accident was that Beijing Defuxiang Catering Management Co., Ltd. illegally placed liquefied natural gas cylinders and evaporators indoors. When replacing liquefied natural gas cylinders, improper operation caused natural gas gasification leakage, and the gas alarm system did not arrange personnel on duty, and the alarm information was not effectively disposed, which eventually led to flash explosion.
The relevant departments imposed an administrative penalty of 200,000 yuan on Beijing Defuxiang Catering Management Co., Ltd. For Changqing Business Center, a gas supplier who illegally engaged in gas business activities without obtaining a gas business license, the urban management department has handed it over to the urban management law enforcement department for investigation.
Yang, an employee of Changqing Business Center, privately carved the official seal of Beijing Yanxinhu LPG Co., Ltd. and forged the contract, and the public security organ has filed a case for investigation.
