ABSTRACT

By analyzing the operation characteristics according to the installation location of the heat detector and the existence of crossbeam, the purpose of this study is to figure out how they affect to the safe evacuation time. For this, the operation time of the detector was measured in case of general fire and oil based fire, respectively, applying 3 parameters of the open and closed conditions and the existence of crossbeam. In the general fire, the results showed 7 seconds difference between open and closed conditions, and 150 seconds of operation delay in maximum depending on the existence of crossbeam. In the oil based fire, the results were similar in two cases of the open and closed conditions, but there were 20 seconds difference in maximum depending on the existence of crossbeam. In case of general fire, the spreading speed of fire was slow, but the spreading speed was fast in the oil based fire, which resulted in these differences. In addition, the number 5 detector which was close to the wall operated most slowly and it was possible to confirm that the existence of wall and crossbeam affected the operation time of the detector. Thus, to secure the safe evacuation time effectively, it is highly required to review the national fire safety code(NFSC) on the clearance distance and design direction of the wall and the crossbeam.
