SHENZHEN has launched a city-wide inspection on building safety following the collapse of a toy factory in Longgang district last month, according to reports by Shenzhen media yesterday. At least 16 ''major'' hidden deathtraps were discovered by city inspectors and orders were immediately issued to halt their constructions pending further examination, the Shenzhen Commercial Daily reported. The inspectors, from the city's Construction and City Planning Bureau, specifically looked into private houses built by rural farmers, multi-storey apartments and some public projects. Three special taskforces were destined for the Bao'an district where a large number of factories are located. The 16 deathtraps included the Yongfu Building, Xinan Market and a pedestrian flyover near the Nantou Checkpoint - one of several checkpoints separating the Shenzhen Special Zone from the rest of Guangdong Province. A factory in Longgang district and two school canteens were torn down after they were certified ''dangerous buildings'' by the inspectors. Two cinemas in Xili and Shahe districts were ordered to stop business after the buildings were found to be dangerous, the daily said. Individual buildings in the Luohu district were also found to be unsafe and their owners have been ordered to repair them after they were fined. The daily said the Shenzhen authorities would soon close down and expel construction teams and architects who were found responsible for the dangerous buildings. Official accounts said at least 11 workers died and dozens more were injured in the collapse of the Xie Cheng Toy Factory in Longgang district last month. Shenzhen, the fastest growing special economic zone in China, has been widely criticised for sacrificing public safety for business. Despite the frequent occurrence of industrial accidents, none of the government officials had been disciplined. Foreign city planners have warned that Shenzhen which has witnessed exponential growth over the past decade faced serious shortages in public emergency services, such as too few fire stations and an inadequate water supply.
