Abstract
In this study, we found that the release and dispersion of ammonia can create hazardous atmospheres using FLACS software. In General, ventilation or gas detector installations are recommended as preventive measures to control explosion incidents. However, the ventilation installations cannot be applicable to the refrigeration facility that uses ammonia as refrigerating medium, because the freezing room should be sealed. From the accident investigation of the explosion case, we suggested that all electronic devices were needed to be switched by explosion proof devices, and communication facility was also needed to be installed to announce to all employees within a building in case alert condition like ammonia releases occurred.
