制造商和新建EASA认证的大型飞机和大型直升机的运营商现在必须逐步淘汰哈龙在便携和方便的内置系统灭火剂. 哈龙是灭火非常有效, 但它也被认为是由气候专家污染物.
据欧洲航空安全局, the aim is to gradually mitigate the environmental impact that Halon extinguishing agents in firefighting equipment have on the ozone and climate, and to progressively achieve a “Halon-free aviation, which balances the environmental concerns with safety-enhancing and cost-efficient rules.”
Under this requirement—new EASA Part 26.170 和 26.400—operators of large airplanes and large helicopters for which the first individual certificate of airworthiness is issued on or after Feb. 18, 2020, shall ensure that the built-in lavatory fire extinguisher does not use Halon. The Halon ban applies to portable extinguishers on aircraft newly certified on or after May 18, 2019.
Although EASA has taken the lead on this ICAO-recommended standard, many other national aviation regulatory authorities have not yet moved to ban Halon. 事实上, the FAA requires the use of Halon 1211, or its equivalent, in the passenger cabins of large airplanes. There is no specific extinguishing agent described by the FAA for large helicopters.
