18、rs, was prepared by the TechnicalCommittee on Airport Facilities. It was issued by the Standards Council on July 2, 2010, withan effective date of July 22, 2010, and supersedes all previous editions.This edition of NFPA 409 was approved as an American National Standard on July 22, 2010.Origin and De
19、velopment of NFPA 409The original fire protection recommendations for the construction and protection of airplanehangars were published by the National Board of Fire Underwriters (NBFU), now the AmericanInsurance Association, in 1930. Revisions were issued by the NBFU in 1931, 1943, 1945, and 1950.T
20、he 1943, 1945, and 1950 editions were published as NBFU Pamphlet 85. In 1951, the NationalFire Protection Association organized a Committee on Aircraft Hangars, to which the NBFU andother interested groups lent their support. The NFPAs first standard on aircraft hangars wasadopted in 1954, and the N
21、BFU adopted the same text, rescinding its 1950 standard. Revisionswere made in 1957 and 1958 by the NFPA committee. In 1959, a reorganization of the NFPAaviation activities resulted in the assignment of NFPA 409 to the Sectional Committee on AircraftHangars and Airport Facilities, which prepared the
22、 1960, 1962, 1965, 1966, 1967, 1969, 1970,1971, 1972, 1973, and 1975 editions. In 1978, the sectional committee was reorganized as theTechnical Committee on Airport Facilities and completed a revision to NFPA 409. The documentunderwent extensive editorial revision and partial technical revision in 1
23、984 and was again revisedin 1990 and 1995.For the 2001 edition, the fire protection requirements for Group I hangars were exten-sively revised, and new criteria were added for membrane-covered rigid-steel-frame-structurehangars.The 2004 edition of this standard was a partial revision.The 2011 editio
24、n of this standard is also a partial revision. Criteria have been added toclarify where sprinklers are required for smaller hangars such as those used by general avia-tion entities. Unenforceable terms have also been removed to comply with the Manual of Stylefor NFPA Technical Committee Documents.40
