- Abstract
- The problem of toxicity in a building fire involves considerations of all the factors which occur during the fire. Despite the fact that experiments with gas toxicity using experimental animals influenced by temperature, humidity, smoke, etc., in addition to gases the results are frequently analyzed only from a point of view of gaseous component. As the present study has clarified, such environmental conditions as temperature, humidity, etc., are also important factors which cannot be neglected under their certain level-conditions. In particular, the evaluation of toxicity in terms of gas-analysis values is the important subject for advancement in future study. Furthermore, in order to clarify the correlation between the toxicity expressed in terms of the analysis values and that obtained by animal experiments, the weight function of such physical factors as smoke, temperature, humidity, etc., as experimental conditions must be elucidated beforehand. Although tendencies in each single factor such as smoke, oxygen, temperature, and humidity were only obtained in the present study because various mice and different mice monitors were used, a further carefully thought out study is required in order to clarify the correlation between each factor.
