NGK Insulators announced the cause of the fire that occurred on September 21, 2011 involving the NAS (sodium-sulfur) batteries for electricity storage that it has manufactured. NGK also announced safety enhancement measures and the resumption of factory operations. NGK has worked to find the cause of the incident and implement countermeasures since it happened. Recently, a third-party investigation committee, with Japan's Hazardous Materials Safety Techniques Association serving as secretariat, reviewed the cause of the fire and containment measures, and judged that the details regarding both were reasonable and appropriate. Based on the results of this investigation, NGK decided to voluntarily implement safety enhancement measures, including a monitoring system, under the guidance of the Fire and Disaster Management Agency. By implementing these safety enhancement measures, customers can be assured of their NAS batteries because the batteries now have more safety features than previous ones. http://www.ngk.co.jp/english/announce/111031_nas.html
