Two executives responsible for the pipeline that exploded in Qingdao last week - killing at least 55 people and injuring 145 - were suspended yesterday as state oil giant Sinopec announced that the pipeline would be permanently shut down. Tian Yimin and Qian Jianhua were suspended from their respective roles as party secretary and general manger of Sinopec Pipeline Storage and Transportation, the Sinopec subsidiary responsible for their pipeline. Sinopec said it would decide on any disciplinary action after a full investigation. Other pipelines carrying oil or chemicals through two central streets in the city's Huangdao district are to be rerouted, the local publicity office said. The city said details would be released for public consultation later. Residents have raised concerns about the safety of the oil pipeline system running under residential areas of Qingdao. More than 100 people living near the accident site protested for a second day outside the government headquarters of Huangdao district yesterday morning, demanding to be relocated for their safety. "We have no idea about the details of the underground oil pipelines that are planted so close to us," said Xu Zhihui, a local resident. "Huangdao is more like a bomb now." Scuffles briefly broke out between protesters and police, but there were no injuries. Qingdao Mayor Li Qun called for greater efforts to maintain order in the city and said those spreading rumours would be punished, the Qingdao Daily reported. Investigators have blamed the leak and subsequent explosion on poor maintenance. The authorities have also been criticised for not evacuating people from the area quickly after the leak was found. President Xi Jinping visited the site of the blasts earlier this week and urged local authorities to ensure care for the people affected by the disaster.
