29、. All Rights Reserved. NFPA 241 Standardfor SafeguardingConstruction,Alteration,andDemolitionOperations 2013Edition This edition of NFPA 241, Standard for Safeguarding Construction, Alteration, and Demolition Operations, was prepared by the Technical Committee on Construction and Demolition. It was

30、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 241 was approved as an American National Standard on Decem- ber 17, 2012. OriginandDevelopmentofNFPA241 Work on the subject of construction, a

31、lteration, and demolition operations began in 1930 when the NFPA Committee on Construction Operations developed the document, Recom- mended Good Practice Requirements for Building Construction Operations. This text was adopted by the NFPA, with revisions, in 1933. In 1942, a tentative revision was s

32、ubmitted, and, while no official action was taken, the revision was published subsequently for information purposes in Volume III of the National Fire Codes published by the NFPA. The NFPA Committee on Building Construction had jurisdiction over this standard when a tentative text prepared by that c

33、ommittee was adopted at the 1957 NFPA Annual Meeting. That text was unanimously approved by the NFPA in 1958. Complete revisions were adopted by the NFPA in 1968 and 1973. An editorial revision was approved in 1975 that brought the standard into conformance with the NFPA Manual of Style. The standar

34、d was substantively reconfirmed in 1980. When the document was reconfirmed in 1980, it came under the Technical Committee on Building Construction. The 1986 edition represented a complete rewrite, which was the result of a comprehensive review by the committee. The 1986 update changed the format in

35、which the safeguards were presented. Chapters 1 through 5 were general in nature and applied to both construction and demolition processes. Chapter 6 presented the specifics associated only with construction processes. Chapter 7 addressed the specifics of demolition. A new Chapter 8 in- cluded manda

36、tory references with which various provisions of the standard were required to comply. Nearly 20 codes and standards were referenced in a mandatory fashion. The 1986 edition also expanded the treatment of items related to an overall construction and demolition fire safety plan. Definitions were expa

37、nded and added to cover terms with meanings that were unique to the standard. Temporary heating equipment was required to be listed. The section on smoking was expanded. Trash disposal was broadened to include housekeeping. Outside chutes, fire cutoffs, and explosives used in demolition were ad- dre

38、ssed. Material on temporary standpipes was included in this edition. The 1989 edition included a complete rewrite of the section on roofing operations and greatly expanded the associated appendix items to address torch-applied roofing in addi- tional detail. A new chapter on underground operations w

39、as added. Revisions to the 1993, 1996, and the 2000 editions mainly consisted of reformatting and clarifications. The 2004 edition changes mainly consisted of the elimination of exceptions and the rever- sal of units of measurement for compliance with theManualofStyleforNFPATechnicalCommit- tee Docu

40、ments. Revisions for the 2009 edition included a requirement for a 2-hour fire watch following torch-applied roofing operations and new provisions for exterior trash chutes. Revisions for the 2013 edition include additional requirements for temporary heating equipment, an expansion of items needed i

41、n a construction or demolition fire safety pro- gram, and an updating of references related to underground air quality. 2411 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.TechnicalCommitteeonConstructi
