The purpose of this study is to analyze four cases of firefighter burns in various fire scenes and to find prevention measures to decrease firefighter injuries. Among the analysis reports prepared by the National Fire Research Institute of Korea from 2016 to 2020, four burn-related accidents are summarized and the main causes are conveyed. The four accidents include second-degree burns from using extinguishers during containment of fires; nine firefighters burned due to re-ignition in the LPG car repair shop; two firefighters injured with third-degree burns from using fire extinguishers during life-saving events in residential housing; and injuries from the radiant heat of the tank BLEVE near the factory fire. These cases are comprehensively investigated in their respective scenes and analyzed based on the fire site investigation reports from the fire department and related theoretical explanations of risk for each accident scene. In the third case study, some experimental research is conducted to evaluate the risk involved with the use of safety gloves. This is evaluated by reviewing Fire Tactics and Standard Operational Procedures (SOP) to determine improvements and recommendations for an efficient firefighting response. Results show that the main causes of burn accidents are the insufficient use of personal protective equipment (PPE), such as safety gloves, and the failure to follow firefighting tactics or SOPs. Through the accident investigation and assessment, it is concluded that to reduce the frequency of burn accidents, the performance of firefighting equipment, SOPs, protection tactics, and safety policy systems require improvement. -

본 연구는 급류지역 수로관 시설물에서 수난구조 활동 중 반복적으로 발생하는 소방공무원의 순직사고를 예방하기 위해 사고 현장을 조사⋅분석한 정보를 바탕으로 수리모형실험을 수행하였다. 실험 결과, 수로관에 가까워질수록유속이 빨라졌으며, 최대 유속이 가장 큰 폭으로 상승한 경우에는 수로관 전면 최대 유속보다 수로관 후면 최대 유속이 약 3.99배 높았고, 수로관 단면적 정면에서는 수로관 위쪽보다 아래쪽 유속이 더 빠른 경향을 보였다. 각 부위별 최대 유속은 수로관 입구를 기준으로 통과 전(10 cm)은 1.65 m/s, 통과 전(5 cm)은 2.63 m/s, 수로관 통과 시에는7.12 m/s, 수로관 통과 후(5 cm)는 5.33 m/s로 측정되었다. 평균 유속은 통과 전(10 cm) 0.94 m/s, 통과 전(5 cm) 1.75m/s, 수로관 내부는 5.53 m/s, 수로관 통과 후(5 cm)는 4.64 m/s로 측정되었다. 연구 결과를 바탕으로 관련 SOP, 지침등을 고찰하고, 현장 대원의 수난구조 활동과 안전사고를 예방하기 위한 권고 및 지침 보완사항(안)을 제시하였다. In this study, waterway modeling experiments were conducted by incorporating the information obtained by analyzingaccident sites to prevent frequent accidents of firefighters that occur during water rescue operations conducted near waterpipes in rapid flow waterways. Based on the conducted experiments, it was observed that the flow velocity increased withdecreasing distance from the water pipe. Furthermore, the maximum flow velocity was found to be 3.99 times higher atthe posterior end than at the anterior end of the water pipe, and the flow velocity was found to be higher at the lowerside than at the upper side of the water pipe’s anterior end. The maximum flow velocity was measured to be 1.65 m/sat a distance of 10 cm from the entrance to the pipe, 2.63 m/s at a distance of 5 cm from the entrance to the pipe, 7.12m/s within the pipe, and 5.33 m/s at a distance of 5 cm from the pipe’s exit. The average flow velocity was measuredto be 0.94 m/s at a distance of 10 cm from the entrance to the pipe, 5.53 m/s within the pipe, and 4.64 m/s at a distanceof 5 cm from the pipe’s exit. Furthermore, in this study, relevant standard operating procedures and regulations were takeninto consideration. Based on the results obtained from this study, recommendations and guidelines were then accordinglydevised for preventing accidents of firefighters that occur during water rescue operations.
