为分析不同应激条件下受限空间内人员疏散时间规律,基于受限空间环境与安全人工智能仿真试验系统,开展气体灭火剂IG541不同体积分数环境中人员生理影响试验研究,在某电子设备厂房人员进行了疏散试验,分析疏散时间与气体体积分数间相关关系。试验结果表明,随着体积分数增加试验对象心率显著加快;部分试验对象在体积分数为30%情况下出现窦性心律过速现象,体积分数超过30%时部分测试者舒张压超过90 mm Hg、收缩压超过120 mm Hg。疏散时间与灭火气体体积分数存在明显正相关关系。
In order to analyze the regularity of evacuation time in confined space under different stress conditions and based on confined space environment and artificial intelligence artificial intelligence test system, this paper carried out experimental research on physiological effects of IG541 gas in different volume fraction environment. In an electronic equipment factory The evacuation test was conducted to analyze the correlation between evacuation time and gas volume fraction. The results showed that the heart rate of the test subjects increased significantly with the increase of the volume fraction. In some subjects, the sinus tachycardia occurred when the volume fraction was 30%. When the volume fraction exceeded 30%, the diastolic blood pressure of some subjects exceeded 90 mm Hg, Systolic blood pressure exceeds 120 mm Hg. There was a clear positive correlation between evacuation time and volume of fire extinguishing gas.
