30、This edition of NFPA 122, Standard for Fire Prevention and Control in Metal/Nonmetal Miningand Metal Mineral Processing Facilities, was prepared by the Technical Committee on MiningFacilities. It was issued by the Standards Council on November 11, 2014, with an effective dateof December 1, 2014, and

31、 supersedes all previous editions.This edition of NFPA 122 was approved as an American National Standard on December 1,2014.Origin and Development of NFPA 122In 1978 the Technical Committee on Mining Facilities, through its membership and currentMine Safety and Health Administration regulations, ide

32、ntified the need for guidance in storageand handling of flammable and combustible liquids in underground nonmetal mines. The firstedition of NFPA 122 was approved in 1986 as a result and was titled NFPA 122, Storage of Flammableand Combustible Liquids Within Underground Metal and Nonmetal Mines (Oth

33、er than Coal). The secondedition was issued in 1990 and included a variety of minor editorial changes to provide consis-tency with the other NFPA Mining Facilities documents.The 1995 edition was a complete revision that focused the document on the overall fireprotection of metal and nonmetal mines,

34、as indicated by the documents new title, NFPA 122,Standard for Fire Prevention and Control in Underground Metal and Nonmetal Mines. Furthermore,this edition incorporated the requirements that were previously included in NFPA 124, Stan-dard for Fire Protection of Diesel Fuel and Diesel Equipment in U

35、nderground Mines, which was with-drawn. Further changes included editorial corrections and revisions that provided consis-tency with other NFPA mining-related standards.The 2000 edition of the standard was reconfirmed by the technical committee. There wereno technical changes made. The fire risk ass

36、essment material in Appendix A was editoriallymoved to Appendix B.In 2004, the Technical Committee reorganized the mining standards and combinedNFPA 121, Standard on Fire Protection for Self-Propelled and Mobile Surface Mining Equipment, withNFPA 122. The committee also added a new Chapter 13, Fire

37、Protection of Surface MetalMineral Processing Plants. The committee incorporated the concept of conducting a fire riskassessment throughout the standard.For the 2010 edition, the technical committee assigned a task group the responsibility ofrevising NFPA 122 to update the existing fire protection r

38、equirements that were included inportions of existing Sections 4.3 and 7.4 to improve operator safety and the reliability of therequired suppression systems. Similarly, Chapter 12, Fire Prevention and Fire Protection ofSurface Mining Equipment, was completely revised to make it consistent with fire

39、protectionindustry practices and the updated provisions in NFPA 120, Standard for Fire Prevention andControl in Coal Mines.Concurrently, another task group was assigned the responsibility of revising NFPA 122 toinclude fire protection requirements for hydro-metallurgical solvent extraction (SX) plan

40、ts.This resulted in two new sections being added into Chapter 13, Section 13.18 for new andexisting hydro-metallurgical solvent extraction (SX) plants and Section 13.19 for new hydro-metallurgical solvent extraction (SX) plants. Sections 13.18 and 13.19 include a fire riskassessment of the facility

41、and requirements for fixed fire suppression systems. To supportthese new sections on hydro-metallurgical solvent extraction (SX) plants, additional refer-ences and definitions were added to Chapters 2 and 3, respectively.1221NFPA and National Fire Protection Association are registered trademarks of
