Fire ranks the first among all of these disasters; the accompanied high temperature and heat, the smoke, and toxics often provoke serious personnel casualties and the property loss. Fire Services Act specifies that "fire prevention", "disaster relief", and "emergency medical service" are three major tasks; therefore, on-site firefighters always involve in direct management and operation to the disasters. The special features of the work often endanger firefighters with fatal working environments with higher probability on casualties comparing to other occupations. According to Fire Departments’ statistics, the annual fire cases, especially the accidents in buildings, have raised since 2015. The accumulation of high fever by fire with dense smoke in the closed space hardens the rescue, lowers visibility with worse vision, and endangers firefighters with the risk of falling into holes by unfamiliarity to buildings. On the other hand, the destruction of buildings imposes plenty of fresh air to boost the combustion by flashover or backdraft, and becomes the main reason to jeopardize firefighters’ lives. The application of infra-red thermal imager favors the above fire rescue with less deficiency as well as firefighters with identified recognition to internal environments for successful search tasks with less elapsed time; the equipment’s bias against accidents gains the attention of fire units gradually. This research compiles all the on-site rescue duty data of firefighters, conducts samples by questionnaire, measures by the on-site fire service, analyzes by SPSS statistical method, and checks the service efficacy with or without the thermal imager. Results, based on the analysis with T-test independent samples, indicate the significant difference, t=3.899, p<. 001, between the thermal imager and “fire service efficacy” by significant test. The average result show the “fire service efficacy” of crews "with" thermal imager is M1=3.7791, which is bigger than M2=3.3037 by those “without” thermal imager. (M1: crews with thermal imager; M2: crews without thermal imager). The auxiliary of thermal imager to diverse services does can upgrade efficiency with less injury by accidents, but the imager can only play the role as aid with limits; the traditional rescues and experiences are still required with draft of relevant standard operation process for developing the best effect of the imager to the fire rescue.
