25、actice forFire Protection for Hydroelectric Generating Plants2010 EditionThis edition of NFPA 851, Recommended Practice for Fire Protection for Hydroelectric GeneratingPlants, was prepared by the Technical Committee on Electric Generating Plants. It was issuedby the Standards Council on October 27,
26、2009, with an effective date of December 5, 2009,and supersedes all previous editions.This edition of NFPA 851 was approved as an American National Standard on December 5,2009.Origin and Development of NFPA 851The Committee on Non-Nuclear Power Generating Plants was organized in 1979 to haveprimary
27、responsibility for documents on fire protection for non-nuclear electric generatingplants. The Hydroelectric Subcommittee was formed in 1982 to write this document. The firstedition of NFPA 851 was issued in 1987 and revised in 1992. The 1996 edition containedminor changes to clarify the life safety
28、 recommendations and generator windings protection.The 2000 edition editorially revised Chapter 2 to be consistent with NFPA 850, RecommendedPractice for Fire Protection of Electric Generating Plants and High Voltage Direct Current ConverterStations. In addition, the document was revised to clarify
29、the requirements for fire suppressionsystems for generator windings of different composition.The 2005 edition of NFPA 851 was restructured to conform to the requirements of theManual of Style for NFPA Technical Committee Documents. There were changes made to clarifyexisting recommendations under 5.2
30、.2.3 and 5.2.2.4 using new artwork. Other changes in-cluded coordination of similar recommendations from NFPA 850, Recommended Practice forFireProtection for Electric Generating Plants and High Voltage Direct Current Converter Stations.The 2010 edition of NFPA 851 now includes a chapter containing r
31、ecommendations for afire protection design process and a fire protection design basis document (new Chapter 4).An annex has been added showing an example of a Fire Protection Design Basis document.The chapter on Fire Risk Control Program has been moved to a new Chapter 9.The use of compressed air fo
32、am systems and fast-depressurization systems has been recog-nized, and recommendations for the use of these systems are now included.8511NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.Technical Committe
