Jiang Fan, former general manager of Dalian Petrochemical Company in Liaoning Province's coastal city of Dalian, was replaced by Leng Shengjun, former general manager of Daqing Refining & Chemical Company of CNPC, according to its official website.

The Dalian branch has been the scene of two fires in the past two months. The latest incident occurred when a diesel oil tank caught fire on Monday. Fortunately, no one was injured or killed in the accident.

On July 16, a fire was triggered by a leak in a distillation device at the Dalian branch. No one was killed or injured as a result.

The CNPC also decided that the corporation would set up its own investigation team to assist with an on-going investigation conducted by the municipal work safety watchdog, according to its website.
