The aim of this paper is to analyze possibilities of metal fire detection using various types of fire detectors, and find the most convenient type of detector. Metal fires belong to class D fires, and demand extinguishing agents which work by smothering and heat absorption. On the other hand, it is too risky to use heat generated by fire for early-stage detection due to high heat release rate. Some metals burn with smoke, but during the fire, most of them produce significant ultraviolet and infrared component of radiation which can be used for detection. Therefore, this paper analyzes the possibility of using a flame detector in case of metal fires, as well as sitting and spacing of flame detectors for metal fire detection at its earliest stage.
