On Aug. 6, 2019, a large-scale fire broke out at a plant in Anseong, killing one firefighter, injuring 10 people and burning a warehouse. NISI reported by debris analysis that the AIBN(Azobisisobutyronitrile) was stored in the estimated ignition location. The AIBN is a “self-reactive substance”, which is sensitive to shock or friction and has a high risk of explosion, due to adverse reactions at air temperatures above 40℃. The risk of explosion with the reference material, BPO(Benzoyl peroxide) is compared, by measuring the explosive pressure, velocity and onset temperature according to the capacity of the AIBN, and proposed a policy for preventing fire by deriving the appraisal technique through qualitative analysis of GC/MS.
