This study examines the fire safety performance of hospital sprinkler systems under Korean standards by analyzing the impact of different sprinkler head types on Available Safe Egress Time (ASET). Four simulation scenarios were developed: (1) no sprinkler system, (2) fast response heads, (3) special response heads, and (4) standard response heads. A fire was assumed to originate on the first floor, and simulations were conducted using PyroSim software. ASET was evaluated in terms of temperature, visibility, carbon monoxide (CO), and oxygen (O₂) concentration. The results showed ASET values of 354 s, 394 s, 354 s, and 355 s, respectively. Fast response heads demonstrated the best performance, increasing ASET by 11.30% on the first floor and 8.96% on the second floor compared to no sprinklers. These findings indicate that sprinkler activation significantly enhances evacuation safety, with the greatest effect observed on the fire-origin floor.
