| Outline of Final Research Achievements |
Scorched odor emitted from various materials gave ambiguous atmosphere when their oxidative combustion proceed. The odor generated from the oxidative combustible from woods and plastic were measured and assigned to their chemical species. Mixed odor of the burning Cedar with kerosene was measured to simulate the odor of incendiarism cases. The peak intensity of odor from wood appeared at around of 250-300 deg. C of thermally degradation period and which corresponds to CO, methane, and aldehyde. Tatami mats (including PS foam) gave odor of PS. The odor from the early stage of fire was detected earlier than or almost equal to the detection of the smoke. The odor detecting system could detect the early stage of fire earlier than or almost equal to the ordinal fire detecting system. The odor could detect CO, aldehydes, and other small molecular spices. It is expected that the odor detecting system could be the next generation fire detecting system.
