Abstract:

In order to effectively prevent and reduce fire accidents in buildings, 58 of such accidents were collected based on 24 Model, and individual and organizational factors leading to their frequent occurrence and evolution paths were analyzed. Then, an evolution path diagram was developed. The results show that among all direct causes, the more frequent ones are violation of rules and regulations by individuals, supervision responsibility not in place and failure of production site design to meet requirements of emergency evacuation. And indirect causes include problems in safety knowledge, consciousness and habits of accident parties and organization managers, with a frequency of 75.86%, 84.48% and 56.90% respectively. In terms of fundamental causes, lacks of safety production responsibility system, fire hazard investigation and management system and safety training system all feature a frequency of over 85%, while for root causes, the most frequent ones are relatively low importance of safety and inadequate understanding of main responsibilities for production safety.

Key words: building fire, 24Model, reason analysis, evolution path, prevention strategy
