摘要

Carbon dioxide(CO_2) is a nontypical toxic gas in fire, the effects of CO_2 ventilation on human incapacitation has not been noted enough in these years. A quantitative mathematical model methodology is described for addressing the effects of CO_2 ventilation on human incapacitation. The ventilation caused by high concentration of CO_2 is extremely obvious throughout the kitchen grease fire scenario. Most of time in the kitchen grease fire, the ventilation rate caused by high concentration of CO_2 is as much 4.33-8.39 times as that in the normal concentration of CO_2, which means such respiratory stimulation may be cause to inhale more carbon monoxide(CO) in fire toxic gases. The internal dose of CO uptake, may be as much 2.70-7.31 times as the CO_2 ventilation is neglected. The occupants in the mixture of CO, CO_2 and RO_2(reduced oxygen)are more easily to incapacitate than those in only CO and RO_2. If the part of CO inhalation led by CO_2 breath stimulation was ignored, the occupants in the kitchen grease fire would have more about 1.3-3.23 minutes to accomplish escape. Although carbon monoxide, reduced oxygen have direct toxic effects on human incapacitation in fire, carbon dioxide play very important roles in leading to indirectly incapacitate and its harm to human incapacitation should not be underestimated throughout the grease fire in kitchen.
