It was issued by the Standards Council on Novem
31、ber 11, 2014,with an effective date of December 1, 2014, and supersedes all previous editions.This edition of NFPA 850 was approved as an American National Standard on December 1,2014.Origin and Development of NFPA 850The Committee on Non-Nuclear Power Generating Plants was organized in 1979 to have
32、primary responsibility for documents on fire protection for non-nuclear electric generatingplants. Begun early in 1980, the first edition of NFPA 850 was officially released in 1986 as theRecommended Practice for Fire Protection for Fossil Fueled Steam Electric Generating Plants.The second edition o
33、f NFPA 850 was issued in 1990 under the revised title of RecommendedPractice for Fire Protection for Fossil Fueled Steam and Combustion Turbine Electric Generating Plants.This second edition incorporated a new Chapter 6 on the identification and protection ofhazards for combustion turbines.In 1991 t
34、he committee changed its name to the Technical Committee on Electric Gener-ating Plants. This simplified name was made to reflect the committees scope to cover all typesof electric generating plants except nuclear.The 1992 edition of NFPA 850 incorporated a new Chapter 7 on alternative fuel electric
35、generating plants. As part of these changes, the document title was revised to the RecommendedPractice for Fire Protection for Electric Generating Plants. Various other technical and editorialchanges were also made.The 1996 edition of the standard added a new Chapter 8 on fire protection for highvol
36、tage direct current (HVDC) converter stations. In addition, the title was changed to Recom-mended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct CurrentConverter Stations to incorporate the new chapter.The 2000 edition revised the application of the document to a
37、pply to existing facilities, asit is a good industry practice. Chapter 2 was reorganized to be specific to a fire risk controlprogram. The document also clarified that a single water tank is not a reliable water supply,the spacing of hydrants, and lock-out of five suppression systems, and additional
38、 require-ments were added for water mist fire suppression systems.The 2005 edition of NFPA 850 underwent a complete revision to comply with the ManualofStyleforNFPATechnicalCommitteeDocuments. Chapter 2 now contains mandatory references andChapter 3 now contains definitions, and the subsequent chapt
39、ers were renumbered.Additional changes included revised figures in Chapter 5 that are intended to furtherclarify existing requirements and the addition of new annex material on fire protection re-quirements.The 2010 edition of NFPA 850 included a chapter containing recommendations for a fireprotecti
40、on design process and fire protection design basis documentation (the new Chapter4). The chapter on fire risk control program was moved to Chapter 16. New chapters on windturbine generating facilities, solar thermal power generation, geothermal power plants, andintegrated gasification combined cycle

42、ecommendationsfor the use of these systems included.The 2015 edition has undergone a significant revision with the merger of NFPA 851. The recommendations con-tained in NFPA 850 and 851 were aligned, and a new chapter (Chapter 14) was created to provide recommendationsspecific to hydroelectric gener
43、ating plants. Recommendations for aerosol extinguishing systems have been added.Recommendations for active carbon injection systems have been added to Chapter 7, and Chapter 11 has beenexpanded to provide recommendations for fire and life safety involving photoelectric solar power plants.8502 FIRE P

46、tage direct cur-rent converter stations that are covered by the scope of thisdocument.1.2.2 This document provides fire hazard control recommen-dations for the safety of construction and operating person-nel, the physical integrity of plant components, and the conti-nuity of plant operations. Specif
47、ic concerns are generalizedand categorized as shown in 1.2.2.1 through 1.2.2.4.1.2.2.1 Protection of Plant Personnel. Risk of injury and lossof life, in the event of fire, should be controlled. Specific cri-teria should be established for means of egress. When forplant safety and emergency response
48、reasons personnel arenot able to evacuate immediately, specific criteria for ensuringtheir safety until they can evacuate and safe passage to egressroutes should be established.1.2.2.2 Assets Protection. The large capital costs of the struc-tures, systems, and components for the facilities addressed
49、 inthis recommended practice create financial risks for the own-ers, investors, and financiers. Specific criteria should be estab-lished for the mitigation of the risks from fires exposing theseassets.1.2.2.3 Business Interruption. The ability of these facilities togenerate and transmit electricity is important not only to theowners of the facilities but also to the consumers of that en-ergy, including the public. Specific criteria for managing theeffects of fire on the ability to generate and transmit powershould be developed, based on economic and societal consid-er
