Description

Previous research papers reported that smoldering odor generated in building fire is most sensitive signal for occupants. In this study, a link between human response to the unusual occasions and the smoldering odor caused in fire was discussed. The odor concentration of smoldering wood was measured using semiconductor type odor sensors installed at the 56 points on the two-dimensional location in a small test room. From the results of the these experiments, the smoldering odor propagated with air flow and diffused over the room. 24 of 30 persons in total were aware of the unusual smell of the odor and the remaining 6 were aware of the smoke itself. It was concluded that most of human was aware of unusual smell at first in the process of the smell of smoke.
