소듐, 리튬금속화재에 대한 불활성 기체 소화약제의 적용성 분석

다국어 초록 (Multilingual Abstract)

This study aims to assess the application of an inert gas fire extinguishing agent for extinguishing metal fire. Sodium and lithium were used as the metallic combustibles. Testing was executed by altering the oxygen concentrations in the order of 21, 6, 4 % by using inert gas fire extinguishing agents including IG-01, IG-541, and IG-100. Since metal features risks of dispersion and explosion, fire was generated by after having adjusted the inert gas extinguishing agent concentration in advance. Regarding the test results, The lower the oxygen concentration, explosion occurred without the manifestation of sparks or a flame. In addition, it was possible to obtain the same results for all of the fire extinguishing agents, namely, IG-541, IG-100, and IG-01. Through this test, it was possible to confirm the characteristics of metal fire and the applicability of IG-01, IG-541, and IG-100 to metal fire. Although it was confirmed that IG-541, unlike the results of NFPA 12 and NFPA 2001, can be applied to metal fire, it is deemed to be the result of the difference in the testing conditions.
