Abstract

One of the fire extinguishers commonly used in various places and also utilized in practical training for students in the Aircraft Accident Rescue Program (Diploma Three) is the Portable Fire Extinguisher (APAR). In their learning, students are not only taught how to use APAR but also about its working system, maintenance, and refilling process. A drawback of the current APAR refilling process is the frequent spillage of dry chemical powder (DCP) and inaccurate measurements. The aim of this research is to design an automatic APAR refilling device that can serve as a learning tool for students. The method used is VDI 2221 (Verein Deutscher Ingenieure), a systematic approach for solving problems and optimizing the use of materials and technology. The outcome of this research is the development of a comprehensive APAR refilling device that integrates the removal of old DCP, refilling with new DCP, and nitrogen charging. The test results showed that the process of suctioning DCP powder and filling nitrogen for a 6 kg cylinder takes 7 minutes and 50 seconds. This tool makes the APAR refilling process easier, minimizes DCP spillage, and saves time during the refilling process.

Abstract

Structural Fire Practice is a firefighting training activity in buildings carried out to equip students with technical skills in dealing with fire incidents in buildings or airport facilities. The risk to physical safety, health, and equipment damage is very high if hazard identification and risk management are not carried out systematically. The purpose of this study is to identify hazards and assess potential risks and provide mitigation so that these risks do not cause more severe consequences. This study was conducted using the Hazard Identification and Risk Assessment (HIRA) approach. The results of the study showed that there were 31 potential hazards covering human, equipment, environmental, and work procedure aspects. The results of the risk assessment showed that four potential hazards were in the intolerable category, namely: SCBA compressors that are not properly maintained, hoses that do not meet standards, manual fuel injection, and backdraft or flashover conditions. Mitigation measures implemented include increased supervision of equipment maintenance, the use of thermal imaging cameras, the implementation of SOPs, and safety training and briefings. The implementation of HIRA in training activities provides significant benefits in increasing safety awareness and reducing the potential for accidents in aviation education environments.
