Abstract
This study attempted to derive an empirical formula that can measure the distance of the carbon monoxide risk radius and oxygen risk radius to ensure safety in the event of a fire in the ESS device of public indoor sports facilities. The derived empirical formula must consider the flow of the air, and in the case of public indoor sports facilities, it presents the airflow speed of 1m/s. Accordingly, it was substituted to the empirical formula and the findings derived the conclusion with 2.92500562m of carbon monoxide risk radius and 0.589756321m of oxygen risk radius. It was verified that in the case air-conditioner · heater is used in the public indoor sports facilities, the carbon monoxide risk radius will expand by around 1m and the oxygen risk radius will expand by around 0.1~0.2m. Moreover, the state suggests ESS installation in public sports facilities, but it is difficult to find manuals or legislation about fire accidents that could occur from installing ESS. Therefore, it is necessary to devise means of revision and policies that consider the ESS facility installation environment.
