All Rights Reserved.NFPA99BStandard forHypobaric Facilities2015 EditionThis edition of NFPA 99B, Standard for Hypobaric Facilities, was prepared by the TechnicalCommittee on Hyperbaric and Hypobaric Facilities and releas
30、ed by the Correlating Commit-tee on Health Care Facilities. It was issued by the Standards Council on April 29, 2014, with aneffective date of May 19, 2014, and supersedes all previous editions.This edition of NFPA 99B was approved as an American National Standard on May 19, 2014.Origin and Developm
31、ent of NFPA 99BIn 1965, when the then Subcommittee on Hyperbaric Facilities was appointed, several hospi-tals were employing hypobaric therapy to treat respiratory diseases. Additionally, NASA and theU.S. Air Force were working with hypobaric chambers for space and air flight. The name of theSubcomm
32、ittee was then changed to Hyperbaric and Hypobaric Facilities, and the initial version ofa document on this subject was prepared. A tentative standard on the subject, NFPA 56E-T, wasadopted at the 1971 Annual Meeting. In May 1972, the document was adopted as an officialstandard. The document was rev
33、ised again for the 1977 NFPAAnnual Meeting.A complete review of NFPA 56E was accomplished for the 1981 Fall Meeting. That editionwas designated NFPA 56E-1982.In 1984, NFPA 56E was combined with 11 other health care documents to form NFPA 99,Standard for Health Care Facilities. NFPA 56E essentially b
34、ecame Chapter 11 of NFPA 99. In thatrevision, the major change made to the 1982 edition of NFPA 56E was a complete revision ofrequirements for Class D chambers to reflect their use for high-altitude training purposes. (Suchchambers do not require as extensive safety precautions as research and clini
35、cal chambers.)During the revision for the 1987 edition of NFPA 99, it was brought to the attention of theSubcommittee on Hyperbaric and Hypobaric Facilities that hypobaric chambers were nolonger used for medical purposes. As such, the material on hypobaric facilities really did notbelong in NFPA 99.
36、 Thus, the Subcommittee proposed that this material be separated fromNFPA 99 and again published as a distinct NFPA document. It was designated NFPA 99B.Minor revisions were made to editions adopted in 1987 and 1990.For the 1993 edition of Standard for Hypobaric Facilities, the one significant chang
37、e was theidentification of the safety director as the person responsible for disseminating informationon hazards associated with operating hypobaric facilities.For the 1996 edition, the major changes included clarifying the application of the docu-ment (Chapters 14) and deleting a Class Ftype chambe
38、r because the committee was un-aware of hypobaric techniques involving artificial atmospheres.The 1999 edition modified several paragraphs to conform to the Manual of Style for NFPATechnical Committee Documents for enforceable language. Other changes were editorial in nature.The 2002 edition include
39、d format revisions. The Manual of Style for NFPA Technical CommitteeDocuments was applied in this documents restructure and format. Introductory material in Chap-ter 1 was formatted for consistency among all NFPA documents. Referenced publications thatapplied to the document were relocated to Chapte
40、r 2, resulting in the renumbering of chapters.Informational references remained in the last annex. Appendices were designated as annexes.Definitions in Chapter 3 were reviewed for consistency with definitions in other NFPA documents,were systematically aligned, and were individually numbered. Paragr
41、aph structuring was revisedwith the intent of having one mandatory requirement per section, subsection, or paragraph.Information that often accompanied many of the requirements was moved to Annex A. Excep-tions were deleted or rephrased in mandatory text, unless the exception represented an allow-an
42、ce or required alternate procedure to a general rule when limited specified conditions exist.99B1NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.The revised format appearance and structure provided conti
43、nuity among NFPA documents, clarity of mandatory text, andgreater ease in locating specific mandatory text.The 2005 edition was slightly modified to clarify some requirements. The ventilation rate was specified by thepurchaser, detection in Class D chambers was made optional, the wiring method in Cl
44、ass E chambers was down-graded, aviation-type masks in chambers were made optional, the hazards of titanium were discussed, and fittingswere listed for oxygen service.The 2010 edition of the standard made minor changes in definitions to correlate with other definitions from theGlossary of Terms.The
45、2015 edition of the standard has been revised to update the referenced standards to the most current editionsavailable and to correct several references to NFPA 99 to match the 2015 edition of that code.99B2 HYPOBARIC FACILITIES2015 EditionCorrelating Committee on Health Care Facilities (HEA-ACC)Mic
