Recently, as natural interiors have been in the spotlight, there is a trend to produce and assemble interior accessories using wood or bark. For small items made in this way, an oil finishing material for wood must be used, and the most used currently is oil stain. Linseed oil, which is classified as a drying oil among vegetable oils, is used as the main ingredient in oil stain. Linseed oil, which is a drying oil, consists of unsaturated fatty acids, and many of them are composed of polyunsaturated fatty acids, so it oxidizes very quickly in the air. Because of these properties, there is a risk of spontaneous ignition due to oxidative heat in the process of improperly processing the painting tools generated after wood painting. Therefore, this study analyzes fire cases that occurred at the fire site, and based on this, deduces the possibility of spontaneous ignition due to oxidative heat in painting tools with oil stains through a re-enactment experiment, and suggests considerations for fire detection and fire prevention measures.
