Purpose: This study aims to draw the problems and improvements of NFSC 103 sprinkler head discharge obstruction prevention standard to increase the fire extinguishing performance of sprinkler system in order to contribute to the protection of people's lives and property in the event of a fire. Method: NFSC 103 was compared to NFPA 13 which is the latest 2019 version in U.S in terms of sprinkler head discharge obstruction prevention. Results: This study found that NFSC 103 doesn't define even the basic concept of sprinkler discharge obstruction. And NFSC 103 doesn't have detailed standard for side wall sprinkler head discharge obstruction prevention as well as the "height" criteria of the "three times" separation rule. Conclusion: NFSC 103 needs a lot of supplements and improvements such as the addition of definition for water discharge obstructions, the adoption of sidewall sprinkler heads standard for preventing water discharge obstructions and the additional establishment of the "three times rule" considering the "height" of obstacles to promote the advance of fire safety standard equal or above fire fighting advanced country and increase the reliability for the suppression performance of sprinkler system.

The purpose of this study is to suggest the development direction of fire safety through the analysis of previous researches in the field of fire fighting. To this end, 929 papers published in the Journal of Korean Institute of Fire Science and Engineering have been sorted by field of study and analyzed for frequency. Accordingly, it was confirmed that researches were conducted in the order of fire chemistry and physics, detection and extinguishing system, fire safety design and management, evacuation and human behavior. In contrast, very little research has been conducted on human behavior, fire safety education, or training. This result is discussed in the article, and suggestions for future research objectives are made.

제연구역에 설치된 방화문의 개폐 기준은 현실과 괴리가 있고 상당 부분 문제점을 가지고 있다. 우리나라 성인 남녀가 일어서 있는 조건에서 오른손으로 미는 힘을 측정한 결과 국가화재안전기준(NFSC 501A)에서 제시하고 있는 개방력과 차이가 큰 것을 확인할 수 있었다. 20대는 평균 103.31N이었고, 30대는 105.27N, 40대는 100.92N, 50대는 97N, 60대는 91.75N 등으로 측정 되었다. 따라서 NFSC 501A에서 제시하고 있는 기준값의 하향 조정이 필요한 것으로 판단된다.
