Purpose: The purpose of the research in this paper is to derive the operating key of the manual that must be included in the preparation of the manual in order to prepare the field action manual that works at the disaster site. We want to contribute to preparing a manual of on-site action that can operate at disaster sites through critical reflection on the fact that many human casualties were caused by the failure of the prepared manual in each national disaster. The study will contribute to preparing manuals for disaster sites. Methods: Research on the field action manual is insufficient. In particular, there has been no research on the key to the field action manual to operate at the disaster site. Nevertheless, the need for this research is due to the urgent need to make manuals that do not work at disaster sites into manuals that can be operated. To this end, in addition to theoretical research, we would like to study based on the insights gained from our experience in the disaster scene and military experience as a professional career soldier. Results: Disaster relief agencies and various related agencies, including disaster relief agencies, will respond to disasters, and in order for them to properly respond to disasters, they must prepare manuals that can operate at disaster sites. In order for the manual to function properly at the disaster site, it must have a key to operate the manual. According to the research, the key to making the manual work at the disaster site is mission and golden time, decision making requirements, a resolution table, and various field information that affects decision making. Conclusion: The reason why the manual did not work at the disaster site was that there was no key for the manual to work. It is expected that the manual will be operated on the spot if the key for operation of the manual derived from this study is prepared by including the on-site action manual during peacetime, and regular training is conducted with the decision maker taking the initiative. It will also give insight to officials preparing and train-ing manuals. We look forward to expanding further research on the working keys of the manual.
