NFPA 501A Standardfor FireSafetyCriteriaforManufacturedHomeInstallations, Sites,andCommunities 2013Edition This edition of NFPA 501A, Standard for Fire Safety Criteria for Manufactured Home Installa- tions, Sites, and Communities, was prepared by the Technical
30、 Committee on Manufactured Housing. It was issued by the Standards Council on November 27, 2012, with an effective date of December 17, 2012, and supersedes all previous editions. This edition of NFPA 501A was approved as an American National Standard on December 17, 2012. OriginandDevelopmentofNFPA
31、501A NFPA activity associated with manufactured homes began in 1937, when NFPA organized its first Committee on Trailers and Trailer Courts. The first NFPA standard covering trailer coach camps appeared in 1939, with revisions in 1940, 1952, 1960, and 1964. A completely new edition was adopted in 19
32、71, and that 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 NFPA edition on February 27, 1976;
33、and the 1977 NFPA edition on October 18, 1977. The 1982 edition of Standard for Firesafety Criteria for Mobile Home Installations, Sites, and Communities superseded the 1977 edition and was adopted by NFPA at its Annual Meeting held in San Francisco in 1982. The 1982 edition was produced by the newl
34、y formed Committee for Firesafety for Mobile Homes (created June 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 improvements for existing
35、mobile homes. Therefore, the 1982 edition excluded all sections of previous editions not considered within the committee scope. Notably excluded were stabilizing and anchoring systems, requirements for piers and footings, and plumbing, including sewage disposal sys- tems. Requirements for park elect
36、rical 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 coordinate the NFPA cha
37、pters in a joint publication with the National Conference of States on Building Codes and Standards (NCSBCS), ANSI A225.1/NFPA 501A. Major changes in- cluded substituting manufactured home for mobile home throughout; deleting Chapter 3, Air Conditioning; expanding Chapter 2, Fuel Supply; and combini
38、ng three appendixes 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/ rehabilitation, maintenance, use, and occupancy of manufactured homes, manufactured home sites, an
39、d manufactured home communities, including accessory buildings and struc- tures. This was a major revision of the scope and the entire standard, and the committee targeted a complete revision of NFPA 501A for 1994. The 1997 edition was a reconfirmation of the 1992 edition of NFPA 501A. The proposed
40、expansion of the scope of the 1992 edition, as noted in the preceding paragraph, was dis- cussed and acted on by the technical committee. The scope of NFPA 501A was not expanded; instead, a new document, NFPA 501, Standard on Manufactured Housing, was generated. NFPA 501 represented the reconstitute
41、d 1977 edition of NFPA 501B,StandardforMobileHomes, which was the basis for the federal Manufactured Home Construction and Safety Standards. 501A1 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.The earl
42、ier editions of NFPA 501A were jointly developed and published by NFPA and NCSBCS as A225.1/ NFPA 501A. 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 were publi
43、shed by NCSBCS as A225.1 (1994 edition). NFPA assumed responsibility for NCSBCS A225 standard in 2003, which was processed concurrently with the 2003 edition of NFPA 501A. The 1999 edition was a reconfirmation of the 1997 edition. In June 1998, NFPA was selected by the U.S. Department of Housing and
44、 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 correlating committee. This expansion occurred during the
45、Report on Com- ments phase of the 1999 edition. The 2000 edition had only a few minor revisions. One revision, in 4.3.5, pertained to updating the water supplies for fire department operations. The other revisions were editorial in nature. The 2003 edition was reformatted to meet the editorial and f
46、ormat-related requirements of the Manual of Style for NFPATechnical Committee Documents. Several definitions were deleted during that revision cycle. The 2005 edition incorporated new requirements for fire separation distances between manufactured homes. The 2009 edition of NFPA 501A was revised to
47、include updates to extracted text where appropriate. In addition, revisions were made that clarified requirements and added new ones for water supplies that serve the site, and newly revised criteria were introduced for fire department access roads and paths. The 2013 edition has been revised to inc
48、lude requirements on retroactivity and equivalencies in Chapter 1. Provi- sions for storm shelters, community buildings, and emergency considerations such as windstorms were added. Several modifications were made to the organization of requirements within the document. 501A2 FIRE SAFETY CRITERIA FOR
