In early August, Supply Chain Matters called attention to a tragic explosion and subsequent fire that occurred at a factory belonging to a Tier Two auto parts supplier located in China. The factory belonged to Kunshan Zhongrong Metal Production Co. and was located in a development zone in the Jiangsu provincial city Kunshan City located about 50 kilometers west of Shanghai. The plant performed plating and polishing of metal hubs that include wheel hubs, a pre-production preparation for aluminum car wheels used by automakers. The explosion was initially believed to have been caused by accumulation of metal dust particles within the facility. At the time of this incident, media reports were unclear as to the full extent of deaths or injuries but the government news agency indicated that 75 workers perished as a result of this accident. The accident was China’s worst industrial disaster in nine years and highlighted continuing problems with workplace safety.

Earlier this week, Chinese investigative authorities reported that the blast killed at least 146 workers, nearly double the initial reported death toll.  Reports in August indicated that there were upwards of 260 workers in the plant at the time of the explosion, and this revised number amounts to a significant casualty toll. According to various global and business media reports, Chinese authorities indicated this week that they would prosecute three senior executives of Kunshan Zhongrong Metal Production as well as 15 Kunshan governmental officials. China’s government further announced the firing of two top officials within the city of Kunshan.

According a published report by the New York Times, Beijing has been holding local government officials and company executives accountable by handing out harsh penalties for work accidents with high casualties. In Kunshan, the investigation team found that local officials were negligent in enforcing safety regulations and that plant management failed to provide safety training for workers, ignored rules on building spacing, density in manufacturing lines, dust cleanup, and use of anti-explosion equipment.

As noted in our August posting, previous incidents of explosions caused from combustible metal parts involved two different suppliers to Apple. In May of 2011, a significant explosion rocked a Foxconn Technology Group production facility located in Chengdu, China where two workers were reported killed. In December of that same year, an explosion at a manufacturing facility of Ri Teng Computer Accessory Co., a subsidiary of Pegatron Corp, located in Shanghai’s Songjiang Industrial Park, injured upwards of 60 workers.

This latest report is a further indication that China’s governmental leaders are indeed clamping down on factory safety standards by holding individual executives and investigative agencies accountable for enforcing worker safety standards.
