Evaluasi APAR Dan Perancangan Sistem Proteksi Kebakaran Aktif pada Workshop Fabrikasi di Gresik

Abstract

The fabrication workshop is a high fire-risk work environment due to the use of heat-producing machinery such as welding, cutting, blasting, and painting equipment. To minimize this risk, a reliable and standardized active fire protection system is essential. This study aims to evaluate and design active fire protection systems, including portable fire extinguishers (APAR), heat detectors, and manual fire alarm pull stations (TPM), in a fabrication workshop located in Gresik. The evaluation and design process refers to NFPA 10 (2022) and NFPA 72 (2022) as the main standards. The evaluation revealed that among the five observed areas, only the main workshop was equipped with fire extinguishers, while the other areas lacked proper protection. Based on hazard classification and area coverage, the minimum required number of extinguishers was eight units; however, only five units were found, all located in the workshop area. Their placement did not fully comply with the maximum coverage distance of 23 meters as regulated. Repositioning and additional units are needed, particularly in the painting, blasting, office, and parking areas. For the detection system, the heat detector layout was designed using a grid pattern, resulting in a total of 16 detectors to ensure full area coverage. Furthermore, one manual fire alarm pull station (TPM) was designed near the main exit, installed at a height and distance no greater than 1.5 meters from the door, in accordance with NFPA 72 Section 17.14.1.3. This study highlights the importance of evaluating and redesigning active fire protection systems to ensure workplace safety in high-risk environments such as fabrication workshops.
