Beijing, Shawwal 8, 1435, Aug 4, 2014, SPA -- The death toll from a factory blast in east China's Jiangsu Province rose to 75 on Monday, when a senior official in charge of the country's work safety said "very serious dereliction of duty" was behind the accident. Another 185 were injured in the blast, which gutted a wheel hub polishing workshop owned by Kunshan Zhongrong Metal Products Co., Ltd. in Kunshan City at 7:37 a.m. on Saturday, Xinhua reported. Yang Dongliang, director of the State Administration of Work Safety and head of an investigation team for the accident, said questions arising from the accident and initial investigation suggested that the factory had long failed to address related risks and problems. There was "very serious dereliction of duty," given the excessive metal dust inside the workshop, which was ignited by flames and caused the blast, Yang told a meeting of the investigation team. --SPA 18:29 LOCAL TIME 15:29 GMT www.spa.gov.sa/w
