We are designed to compare the impact of smoke control systems on Available Safe Egress Time (ASET) in hospital buildings under Korean and Chinese standards. Using PyroSim, three scenarios are simulated: no smoke control, minimum standard exhaust and air supply rates, and a fixed exhaust rate of 18,000 m³/h. Evaluation focuses on temperature, visibility, CO, and O₂. Korean standards mandate a minimum exhaust rate of 5,000 m³/h per zone, while Chinese standards require 15,000 m³/h, producing a 77-second ASET difference. Air supply rules also differ: Korea requires supply to exceed exhaust, while China requires only 50% more. Under a uniform exhaust rate of 18,000 m³/h, ASET differs by over 495 seconds. Findings suggest Korea should raise its minimum exhaust rate and clarify the supply-to-exhaust ratio.
