Chlorine is used in the pre-chlorination and post-chlorination that is a yellow-green gas under standard conditions, where it forms diatomic molecules. Elemental chlorine at high concentrations is extremely dangerous and poisonous for all living organisms, and was historically used in World War I as the first gaseous chemical warfare agent. Chlorine gas is a pulmonary irritant with intermediate water solubility that causes acute damage in the upper and lower respiratory tract. Despite the dangers of chlorine gas, the review of research of the safety-related chlorine facilities in water treatment plant is insufficient. In this study, in the case of the accident outbreak of chlorine gas we evaluated the overall safety in order to provide an optimal design method of the chlorine storage room. First, the gate of chlorine storage facilities should be designed the double doors of iron gate and shutter gate. It is the best secure. Second, in the shutter gate, to block the leaking chlorine gas through the door gap, it is desirable that the injection device of sodium hydroxide is designed. Third, the design of the discharge pressure of the chlorine gas should consider the storage facility size and discharge time. Fourth, at the same pressure, the more number of discharge inlet is more effective for chlorine gas emissions. KCI Citation Count: 0
