Abstract

The research has been conducted to determine the safe residence time for people in a room where the composition of the gas environment has deteriorated due to fire. Carbon monoxide, which is produced by fire, has been found to be lethal for human life and health. Determination of safe time was made based on the study of the composition and amount of fire load in premises and buildings, physical and chemical properties of carbon monoxide, and its effect on the human body. The graphical dependences of the concentration of carbon monoxide in a room, as a function of time, were obtained for eight variants. The results allow authors to determine the possible residence time of a person in a building during a fire before the lethal concentration of carbon monoxide occurs. Studies made it possible to determine the safe residence time of people in a building on fire in a calculated way and to compare it with the normative indicators of the onset of lethal concentration of carbon monoxide in the air. The results obtained determine the safe time during which a person can escape from the building on fire.

在建筑物发生火灾时一氧化碳对人的影响的调查

这项研究是为了确定人们在因火灾而导致气体环境成分恶化的房间里的安全居住时间。由火产生的一氧化碳已被发现对人的生命和健康具有致命性。安全时间的确定是根据对房屋和建筑物火灾负荷的组成和数量、一氧化碳的物理化学性质及其对人体的影响进行研究。在房间里一氧化碳浓度的图形依赖关系，作为一个函数的时间，得到了八个变体。研究结果使作者能够确定在一氧化碳浓度达到致死浓度之前，火灾期间一个人在建筑物内可能停留的时间。研究使人们能够以计算的方式确定人们在着火建筑物中的安全居住时间，并将其与空气中一氧化碳致死浓度开始的规范指标进行比较。得到的结果确定了一个人可以从着火的建筑物中逃生的安全时间。
