Abstract
According to the detailed guidelines for firestops, a through-penetration firestop system should be installed in a building to prevent the spread of fire when there is a gap in fire compartments due to the penetration of pipes, cable trays, etc. However, the inspection of 39 construction sites in Korea has revealed that the existing firestop system involves complex installation prcesses of 4~7 steps, resulting in wide variations in the quality of construction depending on situations at the construction site or the proficiency of workers. Furthermore, there are sites where firestop systems are not constructed due to the lack of knowledge of the builders. Thus, this study aims to set up a proper guide for firestop systems as per the rules, notices, and guidelines of Korea, and suggest a technical improvement plan for through-penetration firestop systems that can achieve the required fire resistive-performance while involving only 1~2 steps for the installation processes.
