Abstract

Fire evacuation drills are crucial for familiarizing occupants with building layouts and evacuation procedures. However, organizing a large drill in an educational site is rare due to the cost effort and data limitations. This paper examines a fire drill in a multi-functional university building in Hong Kong with over 800 participants. While capturing every participant's evacuation process was challenging, key location recordings allowed for a detailed analysis of corridors, staircases, and exits. The analysis revealed that nearly 50% of participants delayed responding to fire alarms, with some remaining in their rooms for over four minutes. Furthermore, exits experienced imbalanced utilization rates, and one was over 200% of design capacity, revealing occupants' preference for familiar routes. Additionally, it highlights the importance of fire drills and discusses future roadmap combining advanced techniques. Overall, this study offers valuable data on human behavior during emergencies, supporting the calibration and validation of evacuation models.

多功能高校高层建筑消防疏散演练多尺度分析

消防疏散演习对于使居住者熟悉建筑物布局和疏散程序至关重要。然而，由于成本和数据限制，在教育站点组织大型演习是罕见的。本文考察了在香港一所多功能大学大楼举行的消防演习，参加者超过800人。虽然捕捉每个参与者的疏散过程具有挑战性，但关键位置的记录允许对走廊、楼梯和出口进行详细分析。分析显示，近50%的参与者对火警反应迟缓，有些人在房间里呆了四分钟以上。此外，出口的利用率不平衡，有一个出口的利用率超过了设计容量的200%，这表明乘客更喜欢熟悉的路线。此外，它强调了消防演习的重要性，并讨论了结合先进技术的未来路线图。总的来说，这项研究提供了关于紧急情况下人类行为的宝贵数据，支持疏散模型的校准和验证。
