| Outline of Final Research Achievements |
It is well known that a scorched odor emitted from various materials in a house when their oxidative pyrolysis and/or combustion reactions proceed. In order to examine the detection of odor fires for residential use, it is necessary to clarify whether or not there is a difference in the odor analysis that occurs in daily life from the viewpoint of false alarms and false alarms. The odor generated during the thermal decomposition of combustibles and the odor of fragrances added to various personal belongings were measured, and whether or not there was a difference in odor was examined. As a result, during the thermal decomposition of combustibles, detection of aldehyde-based substances and an increase in the similarity of odors were observed, but the similarity of fragrances was low. From this, it was suggested that there is a high possibility that fragrances will not cause false detection of fire.

| Academic Significance and Societal Importance of the Research Achievements |
火災発生時には，煙や熱の他にニオイも発生しており，在館者がきな臭いあるいは通常と異なるニオイにより火災に気付づくことも多い．火災発生は新築建物より長年生活した建物で発生することが多い．生活内では様々なニオイが発生しており，ニオイによる火災感知には，生活臭を考慮する必要がある．木材やプラスチックの熱分解時に発生するニオイ分析を行う．また，香料等の生活空間のニオイを定性・定量時に測定し，木材やプラスチック材料等の酸化熱分解時に発生するニオイをそれぞれ明らかにし比較し，生活臭が誤報となる可能性があるか否かを検討し，既存の火災感知器よりも早くに感知する可能性があるニオイ火災感知器の開発の一助となる．
