An inadequate water supply badly hampered firefighters battling a Guangzhou factory blaze in which 15 people died, it was reported yesterday. Chen Yongchao, who owned the Yongfa Foam Rubber Factory in the Baiyun district, has been held for further questioning over Saturday's fire. Fifteen bodies were found on the second floor of the five-storey building. Most windows were sealed with iron bars - a common practice in factories on the mainland to prevent theft - and the exit to the roof was locked. According to newspaper reports in Guangzhou yesterday, although two fire engines arrived 25 minutes after the fire broke out, it took 85 firefighters two hours to put out the blaze because of a poor water flow from nearby fire hydrants. The firefighters had to fetch water from a reservoir further down the road. The Yangcheng Evening News said the factory was told to stop production when safety inspectors visited the building last month. However, Chen had ignored the warning, the paper said. Only two workers managed to escape. They said the fire broke out at about 9am on Saturday, when Chen had told them to put in overtime. They claimed the fire spread rapidly and the smoke from the foam, used for cushions, made it difficult to escape.
