29、y Criteria for Manufactured Home Installa- tions, Sites, and Communities, was prepared by the Technical Committee on Fire Safety for Man- ufactured Housing, released by the Technical Correlating Committee on Manufactured Housing, and acted on by the National Fire Protection Association, Inc., at its
30、 World Fire Safety Congress and Exposition held May 1417, 2000, in Denver, CO. It was issued by the Standards Council on July 20, 2000, with an effective date of August 18, 2000, and supersedes all previous editions. This edition of NFPA 501A was approved as an American National Standard on August 1
31、8, 2000. Origin and Development of NFPA 501A NFPA activity associated with manufactured homes commenced in 1937 when NFPA orga- 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
32、completely new 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 Janu- ary 30, 1975; th
33、e 1975 NFPA edition on February 27, 1976; and the 1977 NFPA edition on October 18, 1977. The 1982 edition of Standard for Firesafety Criteria for Mobile Home Installations, Sites, and Com- munities superseded the 1977 edition and was adopted by NFPA at its Annual Meeting held in San Francisco on May
34、 19, 1982. The 1982 edition was 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 t
35、he maintenance of and improvements 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 sewage
36、 disposal systems. Requirements 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 i
37、n an attempt to better coor- dinate the NFPA chapters in a joint publication with NCSBCS, ANSI A225.1/NFPA 501A. Major changes included substituting “manufactured home” for “mobile home” throughout; deleting Chapter 3, “Air Conditioning”; expanding Chapter 2, “Fuel Supply”; and combining three appen
38、dixes into two. The standard was reconfirmed in 1992 with a plan to expand the scope of NFPA 501A to cover fire safety requirements for the design, construction, installation, alteration/rehabilita- tion, maintenance, use, and occupancy of manufactured homes, manufactured home sites, manufactured ho
39、me communities, including accessory buildings and structures. This was a major revision of the scope and the entire standard, and the committee targeted a complete revision of 501A for 1994. The 1997 edition was a reconfirmation of the 1992 edition of NFPA 501A. The proposed expansion of the scope o
40、f the 1992 edition, as noted in the previous paragraph, was discussed and acted on by the technical committee. The scope of the NFPA 501A document was not expanded but instead a new document was generated. This document, NFPA 501, Standard The Standard is downloaded from Standard Sharing 501A2FIRE
41、SAFETY CRITERIA FOR MANUFACTURED HOME INSTALLATIONS, SITES, AND COMMUNITIES 2000 Edition on Manufactured Housing, represents the reconstituted 1977 edition of Standard for Mobile Homes. This original document was the basis for the federal Manufactured Home Construction and Safety Standards. The earl
42、ier editions of NFPA 501A were jointly developed and published by NFPA and NCSBCS as the A225.1/501A document. The 1997 edition of NFPA 501A was published as a separate, stand-alone document in agreement with NCSBCS and contained only the fire safety requirements. The nonfire safety requirements wer
43、e published by NCSBCS as A225.1 (1994 edition). Currently, there are discussions with NCSBCS in regard to updating the A225.1 document. The discussions include NFPA assuming the responsibilities of maintaining this document within the Manufactured Home Project as a separate NFPA document. The 1999 e
44、dition was a reconfirmation of the earlier document. In June 1998, 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 h
45、omes was expanded into six technical com- mittees and a technical correlating committee. This expansion occurred during the Report on Comments phase of the 1999 edition. The 2000 edition has only a few minor revisions. One revision, in 4.3.5, pertains to updat- ing the water supplies for fire depart
46、ment operations. The other revisions were editorial in nature.
