15、1980 NFPA, All Rights Reserved Standard for the Use of Inhalation Anesthetics (Flammable and Nonflammable) NFPA 56A-1978 NOTE: See TIAs 1-11 in back of document. 1978 Edition of NFPA 56A 56A-1 This edition of NFPA 56A was prepared by the Technical Com mittee on Anesthetizing Agents and is a complete
16、 revision of the 197 3 edition. Many changes in requirements have been made including the following: threshold level for total hazard current of the Line Isolation Monitor; wall-mounted receptacles (1) in nonflammable in halation anesthetizing locations and (2) above the hazardous area of flammable
17、inhalation anesthetizing locations; removal of immersion requirement for portable equipment; and testing requirements for conductive floors in nonflammable inhalation anesthetizing loca tions. When the Technical Committee presented its Report to the Association on May 17 at the 1978 Annual Meeting,
18、the Report was adopted with amendments to Section 2-1, 3-3.1.1, and 4-5.1.6(c) concerning requirements for isolated power systems and the zone of risk definition in anesthetizing locations. Pursuant to the Regulations Governing Committee Projects, the Technical Committee was balloted on the amendmen
19、ts and voted 18 to 4 not to approve the amendments.* The Correlating Committee on Health Care Facilities voted to release the action of the Technical Committee. The actions of the committees were challenged. In accordance with directives of the Council, the Committees reconsidered their action. On r
20、eballots the amendments were not approved and the Standards Council released the Committee Report without the amendments on January 25, 1979. (continued on page 2) *When a Committee does reject an Association Meeting amendment, the Commit tee must also decide if the resultant document is suitable (b
21、ecause those portions af fected by the Association amendment revert to previously NFPA approved text). The Committee voted that the document would be suitable without the amendments and with previously approved text. Thus, the text for the above three paragraphs is that found in the 1973 edition of
22、NFPA 56A. 56A-2 INHALATION ANESTHETICS Origin and Development of NFPA 56A The original edition of NFP A 56 was in the form of an advisory pamphlet entitled “Combustible Anesthetics in Hospital Operating Rooms.“ In 1951 this was expanded and became “Safe Practices for Hospital Operating Rooms,“ and i
23、n 1962 it was renamed “Use of Flammable Anesthetics.“ In 1970 it was expanded to include the use of nonflammable as well as flammable anesthetics. Other changes included th re quirements for a dynamic line isolation monitor, special grounding procedures, and the revision of electrical safeguards to
24、mitigate the hazard of electric shock in anesthetizing locations. The number was changed to NFPA 56A, and the title was changed to “Use of lnhala tion Anesthetics.“ In 1971 amendments included requirements for the equipotential grounding system and the introduction of new designs for plugs and recep
25、tacles for use with the isolated power system. The 1972 edition included changes in testing requirements for antistatic materials, clarification of requirements for the Line Isolation Monitor, additional definitions, and new appendix material. The 1973 edition rearranged material into a more logical
26、 sequence and incorporated some minor revisions and some editorial changes. (continued from page 1) The action of the release of the 1978 edition by the Standards Coun cil was further challenged in April 1979 by the American Hospital Association. The NFP A Board of Directors heard the appeal on Dece
27、mber 5, 1979, listening to the technical arguments by AHA on the need for the 3 amendments, listening to rebuttal arguments by representatives of the Technical Committee, and reviewing the technical actions of the Committee over the past few years. After ex tensive discussion, the Board voted to sus
28、tain the action of the Stan dards Council. In addition, however, the Board responded to several AHA con cerns, including the application of isolated power systems and the retroapplication of the standard as it related to isolated power systems, and directed the Technical Committee to clarify these t
29、wo points as expeditiously as possible, by whatever means within the NFPA Standards-Making System. The Board voted to withhold publication of the document until this occurred so that clarification would be in cluded in every copy of the 1978 edition. As a result of this directive, the Technical Comm
30、ittee issued two Tentative Interim Amendments (TIAs) (TIAs #78-1, and #78-10). COMMITTEE PERSONNEL 56A-3 Committee on Health Care Facilities Correlating Committee Carl W.
