The several floor finishing materials that widely used in entertainment service industry buildings were evaluated according to the method of NES 713. Also, toxic gases of floor finishing materials in combustion without air flow rate were checked as concentration of fire gases variation according to time using gas analyzer. We had estimated the smoke hazard of floor finishing materials in fire. As results of gas analyses using the method of NES 713, toxic index of samples was estimated range of 2～9.7. Therefore, a large amount of toxic gases will release from a floor finishing materials fire and connoted great smoke hazard in fire.

In this study, we tried to evaluate the ignitibility, flammability, heat release rate, and toxicity of five different types of burning artificial leather sofa covers that are widely used in entertainment service industry buildings. As the results of this study, putting the artificial leathers under fire conditions we found out following results auto-ignition temperature was$ 427~437^{\circ}C$, limiting oxygen index was 19~20%; at heat flux of $25 kW\m^2$, ignition time was 10~16s and peak heat release rate was $147~277 kW\m^2$; and at heat flux of$ 35 kW\m^2$, ignition time was 6~9s and peak heat release rate was $176~296 kW\m^2$. The toxic materials discharged from the burning leathers were 5,550~6,290 ppm of CO, 18,500~23,400 ppm of $CO_2$, 110~140 ppm, of HCl, 13~65 ppm of HCN and 145~220 ppm of NOx.
