  • 노즐을 통하여 미세한 물 입자를 뿜어내어 화재를 진압하는 방식은 1930년대부터 응용되어왔지만 하론이 소화 물질로서 개발되어 널리 사용됨에 따라 물분무에 대한 개발이 중단되었다. 그러나 몬트리올 환경회의에 의해 하론이 오존층 파괴 물질로 사용이 제한됨에 따라 대체 소화물질로서 1990년대에 미세 물분무에 대한 연구가 활발히 진행되기 시작하였으며 최근 IMO(세계 해사기구)에서는 2003년부터 건조되는 선박의 소화설비로서 물분무 노즐 사용을 의무화하기 시작했다.(중략)

  • 화재에 대한 소화방법으로서는 점화원의 냉각, 산화제 농도의 감소에 의한 화염의 질식 및 제거소화와 부촉매를 이용한 소화법이 있다. 이중 냉각소화방법은 주로 물을 사용하여 화재를 진압하고 있으나, 유류화재와 전기화재 등에서는 물보다 할론소화약제가 효과적으로 사용되어 왔다. 그러나 할론 등 CFC 계통의 소화약제는 환경오염물질을 내포하며, 지구온난화지수와 오존파괴지수 등이 높아 전세계적으로 그 사용이 중단되고 있다. 이에 대한 대체 기술의 하나로 최근에 관심이 고조되기 시작한 소화기술은 분무 노즐을 이용한 미세물분무(water mist) 소화설비이다.(중략)

  • For sustainable development of air transport, the establishment and application of international standards of environmental protection area is significant. The development and use of alternative fire extinguishing agent to Halon, which is used for the fire extinguishing systems of engine nacelles/APU and cargo compartments, has been requested in order to protect the ozone layer. The ICAO has been active in preparing international standards and recommended practices (SARPs); however, certification of alternative fire extinguishing agents has been postponed due to technical readiness problem.. Consequently, the implementation of SARPs has also been postponed by two years from the end of 2016. to the end of 2018. As such consequences have caused confusion among Member States regarding its implementation, it is necessary to discuss and pay more attention to this issue. ICAO Council and Air Navigation Commission should consider between setting the implementation time frame earlier or giving enough time for mature readiness and preparedness. Also in order to minimize the unnecessary discharge of Halon owned by Member States, it is necessary to consider efficient management methodologies; for example, requesting fire extinguisher manufacturers to recharge in professional ways. For the successful implementation of the SARPs, ICAO developed an implementation task list as including notification of differences, establishment of a national implementation plan, drafting of the modification to the national regulations and means of compliance, adoption of the national regulations and means of compliance. Member States can develop their own rule making process in reference with the ICAO implementation task list. This issue was presented and discussed during the 54th Conference of Directors General of civil aviation, Asia and Pacific Regions which was held in Ulaanbaatar, Mongolia in 2017 with significant attention among participated Contacting States. In this regards, ICAO Council and Air Navigation Commission should consult with Legal Bureau lawyers regarding SARPs preparing process to eliminate difficulties and confusions for proper implementation within effective date.
