This study examines the influence of the atmospheric disturbance caused by a fire in a semi-open parking garage and the resulting rapid drop of toxic gases on evacuation safety. According to a FDS simulation, the air pressure in an atmosphere of 1 kgf/m2 or a windless environment is used, each factor for hazardous escape does not reach a significant level (SFPE Handbook of Fire Protection Engineers). This indicates that even if two sides of an exterior wall are closed, in order to escape, a semi-open space is safe. However, in the industry, there is a debate on whether the influence of a different spatial format and the air pressure in the atmosphere needs to be re-assessed.
