DALIAN -- The general manager of the Dalian Petrochemical Company of China National Petroleum Corporation (CNPC), a leading on-shore oil producer, was removed from his post Tuesday following the branch's second fire in two months, a company source said Wednesday.

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.
