24、 Standard on Aircraft Hangars, was prepared by the Technical Committee onAirport Facilities and acted on by NFPAat its MayAssociation Technical Meet- ing held May 2326, 2004, in Salt Lake City, UT. It was issued by the Standards Council on July 16, 2004, with an effective date of August 5, 2004, and
25、 supersedes all previous editions. This edition of NFPA 409 was approved as an American National Standard on August 5, 2004. Origin and Development of NFPA 409 The original fire protection recommendations for the construction and protection of airplane hangars were published by the National Board of
26、 Fire Underwriters (NBFU), now the American Insurance Association, in 1930. Revisions were issued by the NBFU in 1931, 1943, 1945, and 1950. The 1943, 1945, and 1950 editions were published as NBFU Pamphlet 85. In 1951, the National Fire Protection Association organized a Committee on Aircraft Hanga
27、rs, to which the NBFU and other interested groups lent their support. The NFPAs first standard on aircraft hangars was adopted in 1954, and the NBFU adopted the same text, rescinding its 1950 standard. Revisions were made in 1957 and 1958 by the NFPAcommittee. In 1959, a reorganization of the NFPA a
28、viation activities resulted in the assignment of NFPA 409 to the Sectional Committee on Aircraft Hangars and Airport Facilities, which pre- pared the 1960, 1962, 1965, 1966, 1967, 1969, 1970, 1971, 1972, 1973, and 1975 editions. The sectional committee was reorganized as the Technical Committee on A
29、irport Facilities and completed a revision to NFPA 409 in 1978. The document underwent extensive editorial revision and partial technical revision in 1984 and was again revised in 1990 and 1995. For the 2001 edition, the fire protection requirements for Group I hangars were exten- sively revised and
30、 new criteria were added for membrane-covered rigid-steel-frame-structure hangars. The 2004 edition of this standard is a partial revision. 4091 Copyright National Fire Protection Association Provided by IHS under license with NFPA Not for ResaleNo reproduction or networking permitted without licens
