An experimental study was conducted to statistically compare the ignition potential of Reduced Ignition Propensity (RIP) cigarettes with that of conventional cigarettes using Japanese style bedding, futon, in order to examine the effectiveness of RIP cigarettes in the context of Japanese fire scenario. Number of ignition of futon caused by three different types of cigarettes, namely, one conventional cigarette (Conv.) and two RIP cigarettes using banded paper with either sodium alginate bands (RIPCB) or cellulose bands (RIPMB) was examined in two testing configurations, which are compressed configuration and quasi-crevice configuration. Difference in the number of ignition of futon observed in different test settings were statistically compared by Fisher’s exact test to examine whether experimental parameters such as the cigarette types, materials of futon, and placement conditions contribute to the ignition. Additionally, logistic regression analysis was conducted to examine how the experimental parameters contribute to the ignition. Test results showed no significant difference between Conv. and RIPCB, and between Conv. and RIPMB (as a result of Fisher’s exact test ; P < 0.05) in either test configuration. Filling materials of futon, outer materials of futon, and testing configurations are thought to be greater contributing factors to the ignition at least under the experimental conditions examined in this study.
