高校典型教学实验室火灾危险源系统评价

System evaluation of fire hazard sources in typical teaching laboratories in university

在总结国内外火灾风险评价研究的基础上,分析了高校实验室现状及进行火灾风险评价的意义。以矿业工程国家级实验教学示范中心典型实验室—矿井通风仿真实验室为例,从实验室电路、人员、环境及管理四个方面进行火灾风险识别,建立了实验室火灾风险评价指标体系。采用灰色关联分析确定指标集的权重,结合灰色—模糊综合评价法得出实验室火灾评价模型。以矿井通风仿真实验室为例进行了火灾风险评价实证研究,得出实验室安全等级为"安全",最后根据辨识和评价结果提出相应的防控措施,为同类实验室火灾风险评价和预防提供了一定的借鉴。

Based on the research of fire risk assessment at home and abroad, the current situation of university laboratories and the significance of fire risk assessment are analyzed. Taking mine ventilation simulation laboratory, a typical laboratory of national experimental teaching center of mining engineering, as an example, fire risk identification was carried out from four aspects of laboratory circuit, personnel, environment and management, and a fire risk evaluation index system was established. The weight of index is determined by grey correlation analysis, and the laboratory fire evaluation model is obtained by combining grey-fuzzy comprehensive evaluation method. Taking mine ventilation simulation laboratory as an example, this paper conducts an empirical study on fire risk evaluation and obtains that the level of the laboratory is “safety”. Finally, according to the identification and evaluation results, corresponding prevention and control measures are put forward, which provides certain reference for fire risk evaluation and prevention of similar laboratories.
