Abstract: (254 Views)
Background: Fire is one of the most perilous phenomena, resulting in human and financial losses. Hospitals and medical centers are among the places where a large number of fires occur every year, making the timely evacuation of patients, individuals with disabilities, and staff crucial. The aim of this study was to simulate and analyze the emergency evacuation of individuals in a hospital in Shiraz City, Iran.
Methods: This study was performed in the treatment building of a hospital that lacked emergency exits. Evacuation simulations were performed in both fire and non-fire modes to investigate the impact of smoke and combustion products on the evacuation time of individuals. Fire Dynamics Simulator (FDS)+Evac and PyroSim software were applied to simulate fire and evacuation.
Findings: The results of the emergency evacuation simulation showed that under normal conditions (without a fire), the average evacuation time was 815 seconds, during which 295 individuals successfully evacuated. In contrast, during the fire scenario, when the ventilation system was either operational or non-operational, 10 and 32 individuals, respectively, were unable to exit the building after 900 seconds.
Conclusion: The results of this study demonstrate the crucial role of ventilation systems in preventing smoke from reaching the floors, by making emergency exit doors available.
