30、Technical Committee on Mining Facilities. It was issued by the Standards Council onNovember 11, 2014, with an effective date of December 1, 2014, and supersedes all previouseditions.This edition of NFPA 120 was approved as an American National Standard on December 1,2014.Origin and Development of NF

31、PA 120In 1977, with the formation of the Mining Committee, this standard, NFPA 120, formerlyNFPA 653, was reassigned to the Committee on Mining Facilities. The change in numericalidentity of the standard was in keeping with the numbering sequence assigned to the MiningCommittee for other documents n

32、ow under development. NFPA 120 represents a completerevision of former NFPA 653 and also includes changes in style in accordance with theNFPA Manual of Style.The 1971 edition of NFPA 653, Coal Preparation Plants, was the same as the 1959 edition andwas adopted at the NFPA 1971 Annual Meeting. The 19

33、59 edition of NFPA 653 was preparedby the NFPA Committee on Dust Explosion Hazards and was adopted at the 1958 AnnualMeeting with an amendment adopted in 1959.The 1994 edition of NFPA 120 included a variety of technical and editorial updates. Previ-ous editions not already mentioned include versions

34、 issued in 1984 and 1988.The 1999 edition addressed the need for emergency lighting, expanded the types of por-table fire extinguishers used, and expanded and clarified the types of fire suppression equip-ment used. The water supply requirements also were clarified.The 2004 edition applied the NFPA

35、Manual of Style to the document. It also incorporatedall the appropriate sections of NFPA 121 and NFPA 123, which was done in an effort toconsolidate common requirements.The Coal Mining Task Group for the 2004 edition consisted of the following members:Matt Bujewski, Chair, Marsh Inc.; Tim Gierer, A

36、lltype Fire Protection; Dennis Brohmer, AnsulInc.; Jay Senn, Peabody Energy Group; Charlie Russell, Arch Coal Inc.; Brent Sullivan, CoteauProperties; Carol Boring, Mine Safety and Health Administration; Alex Smith, NIOSH; MarioOrozco, Zurich Services Corp.; Mike Wegleitner, Falkirk Mining Co. (alter

37、nate for BrentSullivan); and Bill Wilson, U.S. Department of Labor (alternate for Carol Boring).For the 2010 edition, the technical committee has revised the fire prevention and fireprotection provisions for coal mines by requiring the use of means to manage the spontane-ous combustion potential of

38、the coal being mined, including adding an inspection plan forcarbon monoxide detection systems. The fire prevention practices for coal mines have beenimproved by referencing the inspection and maintenance practices of fire suppression sys-tems in the corresponding NFPA fire suppression standard. The

39、 Committee has providedimproved fire protection for transformers by referencing NFPA 70, National Electrical Code, andadding NFPA 850, Recommended Practice for Fire Protection for Electric Generating Plants and HighVoltage Direct Current Converter Stations, as an annex reference. Similarly, the stan

40、dard has beenrevised to make it consistent with fire protection industry practices and the updated provi-sions in NFPA 122, Standard for Fire Prevention and Control in Metal/Nonmetal Mining and MetalMineral Processing Facilities.For the 2014 edition, the technical committee rewrote the sprinkler req

41、uirements in amore coherent manner and provided additional guidance for underground sprinkler sys-tems. The committee established a common definition and a protection scheme for self-propelled, mobile, and portable equipment.1201NFPA and National Fire Protection Association are registered trademarks
