Abstract

Introduction: Emergency evacuation from hospitals is a complicated process. This is on account of multiple categories of occupants of hospitals at any given time. This study was conducted using simulation, which simulated emergency evacuation in a teaching hospital. The aim was to identify defects in stairways and exit doors to propose design modifications to facilitate emergency evacuation.

Methods: This cross-sectional study was conducted using Pathfinder software. The stages of the study included (1) map and model preparation, (2) field study, (3) simulation of evacuation, and (4) making feasible changes in the dimension of the hospital stairways and exit doors and examining its impact on the efficiency of evacuation processes.

Results and discussion: In the case where all people can move on their own, the evacuation time was 129.7 seconds. If the occupants of the beds and wheelchairs needed assisted evacuation, the evacuation time was 733.3 seconds, which increased by more than five times. If there were impediments in the building corridors, the evacuation was not complete, and 36 percent of the people could not be evacuated. By considering modification of around 58.6 percent in width and/or area of exit dimensions based on the field visit and its feasibility without making major structural changes, there was a reduction in the evacuation time by 46 percent.

Conclusion: The results showed that the modifications of passages could make significant improvements in the evacuation process. This would also lead to the reduction of evacuation time in emergencies.

医院建筑物紧急疏散的软件模拟及提供纠正措施。
医院紧急疏散是一个复杂的过程。这是因为在任何特定时间,医院的住院者有多种类别。本研究采用模拟的方法,模拟某教学医院的紧急疏散。目的是确定楼梯和出口门的缺陷,提出设计修改建议,以方便紧急疏散。方法:采用Pathfinder软件进行横断面研究。研究的阶段包括(1)地图和模型准备,(2)实地研究,(3)疏散模拟,以及(4)对医院楼梯和出口门的尺寸进行可行的改变,并检查其对疏散过程效率的影响。结果与讨论:在所有人都可以自行移动的情况下,疏散时间为129.7秒。如果床和轮椅上的人需要辅助疏散,疏散时间为733.3秒,增加了5倍以上。如果建筑物走廊有障碍物,疏散就不完整,36%的人无法疏散。考虑到在实地考察的基础上对出口尺寸的宽度和/或面积进行58.6%的修改,以及在不进行重大结构改变的情况下的可行性,疏散时间减少了46%。结论:通过对通道的改造,可以明显改善大鼠的疏散过程。这也将减少紧急情况下的疏散时间。
