NFPA 520 Standardon SubterraneanSpaces 2016Edition This edition of NFPA 520, Standard on Subterranean Spaces, was prepared by the Technical Committee on Subterranean Sp
30、aces and acted on by NFPA at its June Association Technical Meeting held June 2225, 2015, in Chicago, IL. It was issued by the Standards Council on August 18, 2015, with an effective date of September 7, 2015, and supersedes all previous editions. This edition of NFPA 520 was approved as an American
31、 National Standard on September 7, 2015. OriginandDevelopmentofNFPA520 In 1993, a symposium was convened by the United States Fire Administration to examine the problem of fire in subterranean spaces that have been converted for commercial use. The symposium was the result of a fire in a developed s
32、ubterranean space in Kansas City, Kansas, that burned from December 1991 to April 1992. The symposium examined several unique fire and life safety issues that exist in subterranean spaces, including means of egress issues such as orientation and excessive travel distances, poor ventilation, communic
33、ation difficul- ties, and nontraditional behavior of fire. The result was a recommendation to the National Fire Protection Association to develop a standard that addresses fire and life safety in these occupancies. For the 2005 edition, the committee made only minor revisions to the document by add-
34、 ing some definitions, clarifying some provisions that users had found unclear, and expanding several concepts that had been found to work well. For the 2010 edition, the committee found that NFPA 520 generally had been an effective document over the past 15 years. The committee made only minor revi
35、sions, revising two definitions with appropriate extracts from other documents and clarifying the provisions of three subsections. For the 2016 edition, the committee determined that NFPA 520 generally has been an effective document over the past 20 years. The committee made only minor revisions, ch
36、ang- ing the phrase “areas of refuge” to “refuge areas” and updating various reference documents. 5201 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.TechnicalCommitteeonSubterraneanSpaces JackPoole, Ch
