This study was accomplished by measuring the lower and upper flash point with air blowing method and grasping the characteristics of flammability for the three component systems, which are made up of the Benzene-Toluene-o-Xylene and Methylethylketone-Toluene-o-Xylene. These three component systems are widely used in the various industrial fields together with the development of industry. The results are as follows ; 1) Isothermal line is plotted on the triangular diagram for flash points determined in each solutions. From this line, the mixed compositions which indicated the same lower and upper flash points in each different composition could be read on this diagram, if the composition of mixtures are known. 2) Lower and upper explosion limits obtained from the flash points determined for the three component solution are compared with the value calculated from Le Chatelier's law. Especially the lower explosion limits are in a good agreement with the calculated values.

The characteristics of spontaneous ignition of painting waste was investigated at constant ambient temperature in oven. As the results of experiments, the spontaneous ignition temperature decreased as the sample vessel became large, and the spontaneous ignition temperature of the sample in small, intermediate and large vessels was 165.5℃, 144.5℃ and 134.5℃ respectively. The apparent activation energy calculated by the Frank-Kamentskii's thermal ignition theory was 34.73 ㎉/㏖.

The critical spontaneous ignition temperature for activated carbon were observed by performing experiments for granulated activated carbon with varying the period. As the results of the experiments, the critical spontaneous ignition temperature according to period of 0.5hr, 1.5hr and 2.5hr was 177.5, 176.5℃ and 172.5℃ respectively, and the approximate expression of the critical spontaneous ignition temperature obtained for ambient temperature amplitudes was as follow ; δ_c(χ,ω)=δ_c{1-0.381 exp(-0.930·ω^(0.811))}
