Abstract
The risk of casualties is inherently high in the event of a fire in a goshiwon, a residential facility with small single-room accomodations, since the building is divided into a number of small rooms in a single floor among multi-use establishments. Therefore, flame resistant treatment of plywood and wood materials for interior design is required to minimize casualties in the event of a fire. To examine the effect of flame resistant treatment, combustion characteristics of flame resistant treated plywood were analyzed and a real scale fire test was performed by creating a fire area in the actual goshiwon building. The heat release rate of plywood treated with flame retardants was measured 12.4 MJ/m 2 lower than that of untreated plywood, and ignition temperature was 120 o C higher. According to the result of the real scale fire test, time taken to reach the highest temperature was 120 seconds for flame resistant treated plywood and 65 seconds for untreated plywood in the early stages of fire. Therefore, flame resistant treatment was found to have a considerable effect on fire spread protection.
