25、ition of NFPA 501A, Standard for Fire Safety Criteria for Manufactured Home Installations, Sites, and Communities, was prepared by the Technical Committees on Manufactured Housing, released by the Technical Correlating Committee on Manufactured Housing, and acted on by NFPA at its November Associati
26、on Technical Meeting held November 1317, 2004, in Miami Beach, FL. It was issued by the Standards Council on January 14, 2005, with an effective date of February 7, 2005, and supersedes all previous editions. This edition of NFPA501Awas approved as anAmerican National Standard on February 7, 2005. O
27、rigin and Development of NFPA 501A NFPAactivity associated with manufactured homes commenced in 1937 when NFPAorga- nized its first Committee on Trailers and Trailer Courts. The first standard covering trailer coach camps appeared in 1939, with revisions in 1940, 1952, 1960, and 1964. A completely n
28、ew edition was adopted in 1971, and this text was revised in 1972, 1973, 1974, 1975, 1977, and 1982. The American National Standards Institute (ANSI) approved the 1972 NFPA edition on May 8, 1973; the 1973 NFPA edition on December 28, 1973; the 1974 NFPA edition on January 30, 1975; the 1975 NFPAedi
29、tion on February 27, 1976; and the 1977 NFPAedition on October 18, 1977. The 1982 edition of Standard for Firesafety Criteria for Mobile Home Installations, Sites, and Communitiessupersededthe1977editionandwasadoptedbyNFPAatitsAnnualMeetingheld in San Francisco on May 19, 1982. The 1982 edition was
30、produced by the newly formed Committee for Firesafety for Mobile Homes (June 10, 1979), which was charged with the responsibility of developing documents for fire safety criteria for single-family mobile homes, including the installation, sites, and communities, and the maintenance of and improvemen
31、ts for existing mobile homes. There- fore, that edition excluded all sections of previous editions not considered within the com- mittee scope. Notably excluded were stabilizing and anchoring systems, requirements for piers and footings, and plumbing, including sewerage disposal systems. Requirement
32、s for park electrical systems were addressed by reference to NFPA 70, National Electrical Code. Modifications were also made in sections dealing with fuel supply, air conditioning, and life and fire safety. Major revisions to the standard were made in the 1987 edition in an attempt to better coordin
33、ate the NFPAchapters in a joint publication with NCSBCS,ANSIA225.1/NFPA501A. Major changes included substituting “manufactured home” for “mobile home” throughout; deleting Chapter 3, Air Conditioning; expanding Chapter 2, Fuel Supply; and combining three appendixes into two. The standard was reconfi
34、rmed in 1992 with a plan to expand the scope of NFPA 501A to cover fire safety requirements for the design, construction, installation, alteration/ rehabilitation, maintenance, use, and occupancy of manufactured homes, manufactured home sites, and manufactured home communities, including accessory b
35、uildings and structures. This was a major revision of the scope and the entire standard, and the com- mittee targeted a complete revision of 501A for 1994. The 1997 edition was a reconfirmation of the 1992 edition of NFPA 501A. The proposed expansionofthescopeofthe1992edition,asnotedinthepreviouspar
36、agraph,wasdiscussedand acted on by the technical committee. The scope of the NFPA501Adocument was not expanded; instead a new document was generated. This document, NFPA 501, Standard on Manufactured Housing, represents the reconstituted 1977 edition of Standard for Mobile Homes. This original docum
37、ent was the basis for the federal Manufactured Home Construction and Safety Standards. 501A1 Copyright National Fire Protection Association Provided by IHS under license with NFPALicensee=Purdue University/5923082001 Not for Resale, 11/02/2006 02:54:24 MSTNo reproduction or networking permitted with
38、out license from IHS -,-,- The earlier editions of NFPA 501A were jointly developed and published by NFPA and NCSBCS as the A225.1/ NFPA 501A document. The 1997 edition of NFPA 501A was published as a separate, stand-alone document in agree- ment with NCSBCS and contained only the fire safety requir
39、ements. The nonfire safety requirements were published by NCSBCS as A225.1 (1994 edition). NFPA assumed responsibility for the NCSBCS A225 Standard in 2003. It was processed concurrently with the 2003 edition of NFPA 501A. The 1999 edition was a reconfirmation of the earlier document. In June 1998,
40、NFPA was selected by the U.S. Department of Housing and Urban Development to update the federal standards (24 CFR 3280) for manufactured homes.As a result of this selection by HUD, the original technical committee for manufactured homes was expanded into six technical committees and a technical corr
41、elating committee. This expansion occurred during the Report on Comments phase of the 1999 edition. The2000editionhadonlyafewminorrevisions.Onerevision,in4.3.5,pertainedtoupdatingthewatersuppliesfor fire department operations. The other revisions were editorial in nature. The 2003 edition was reform
42、atted to meet the editorial and format-related requirements of the Manual of Style for NFPATechnical Committee Documents. Several definitions were deleted during that revision cycle. The 2005 edition incorporates new requirements for fire separation distances between manufactured homes. 501A2FIRE SA
