23、cilities, was prepared by the Tech-nical Committees on Administration, Electrical Equipment, Electrical Systems, Gas DeliveryEquipment, Health Care Emergency Preparedness and Disaster Planning, Hyperbaric andHypobaric Facilities, and Piping Systems, released by the Technical Correlating Committee on

24、Health Care Facilities and acted on by NFPA at its November Association Technical Meeting heldNovember 1317, 2004, in Miami Beach, FL. It was issued by the Standards Council on January 14,2005, with an effective date of February 7, 2005, and supersedes all previous editions.The 2005 edition of NFPA

25、99 was approved as an American National Standard on February7, 2005.Readers are cautioned that NFPA 99 is structured so that the applicability of requirementsin Chapters 4 through 12 are specified for the health care facilities listed in Chapters 13through 18 and Chapter 21.Origin and Development of

26、 NFPA 99CThe gas systems portion of NFPA 99C originated from NFPA 56F, Standard for NonflammableMedical Gas Systems. This document was incorporated into NFPA 99 during the processing ofthe 1987 edition of NFPA 99.The vacuum systems portion of NFPA 99C originated from NFPA 56K, Recommended Practicefo

27、r Medical Surgical Vacuum Systems. The 1980 edition of NFPA 56K was simultaneously revisedto a standard and incorporated into the 1984 edition of NFPA 99.The 1999 edition reorganized the chapter configuration and added a new Chapter 20 onfree-standing birthing centers.The 2002 edition was revised to

28、 meet the requirements of the Manual of Style. Gas andvacuum piping systems were reorganized to be more user friendly.The 2005 edition added new pipe joining methods to Chapter 5, and Chapter 12 onHealth Care Emergency Management was modified to correlate with NFPA 1600, Standard onDisaster/Emergenc

31、ip-ment, and for electrical, gas, and vacuum systems used for thedelivery and care of infants in freestanding birthing centers.1.2 Purpose.1.2.1 The purpose of this standard is to provide minimum re-quirements for the performance, maintenance, testing, and safepractices for facilities, material, equ

32、ipment, and appliances, in-cluding other hazards associated with the primary hazards.1.3 Application.1.3.1 This document shall apply to all health care facilities.1.3.2 Construction and equipment requirements shall be ap-plied only to new construction and new equipment, except asmodified in individu

33、al chapters. Only the altered, renovated, ormodernized portion of an existing system or individual compo-nent shall be required to meet the installation and equipmentrequirements stated in this standard. If the alteration, renova-tion, or modernization adversely impacts existing performancerequireme

34、nts of a system or component, additional upgradingshall be required.1.3.3 Chapters 13 through 19 of NFPA 99 specify the condi-tions under which the requirements of Chapters 4 through 12of NFPA 99 shall apply in Chapters 13 through 19 of NFPA 99.1.3.4 This document is intended for use by those person

38、allbe approved for the intended purpose by the authority havingjurisdiction.1.5 Units and Formulas.1.5.1* Primary units will be trade units, secondary will be theconversion. Although it is common practice for medical appli-ances to have metric units on their dials, gauges, and controls,many componen

39、ts of systems within the scope of this docu-ment, which are manufactured and used in the United States,employ nonmetric dimensions. Since these dimensions (suchas nominal pipe sizes) are not established by the National FireProtection Association, the Technical Correlating Committeeon Health Care Fac

40、ilities cannot independently change them.Accordingly, this document uses dimensions that are presentlyin common use by the building trades in the United States.1.6 Standard Adoption Requirements.1.6.1 The effective date of application of any provision of thisdocument is not determined by the Nationa

41、l Fire ProtectionAssociation. All questions related to applicability shall be di-rected to the authority having jurisdiction.1.6.2 Enforcement.
