22、PA 560Standard for theStorage, Handling, and Use of Ethylene Oxidefor Sterilization and Fumigation2007 EditionThis edition of NFPA 560, Standard for the Storage, Handling, and Use of Ethylene Oxide forSterilization and Fumigation, was prepared by the Technical Committee on Industrial and Medi-cal Ga
23、ses. It was issued by the Standards Council on December 1, 2006, with an effective dateof December 20, 2006, and supersedes all previous editions.This edition of NFPA 560 was approved as an American National Standard on December 20,2006.Origin and Development of NFPA 560In June 1990, a request was m
24、ade by a manufacturer of ethylene oxide to develop a newstandard for the storage, handling, and use of ethylene oxide for sterilization and fumigation.This request addressed the replacement of the nonflammable mixture of ethylene oxide andfreon with pure ethylene oxide, which was occurring concurren
25、t with the reduced use offreon for environmental reasons. The request was reviewed by the NFPA Standards Council,which published a notice in the August 1990 edition of Fire News asking for public input on therecommendation.At its January 1991 meeting, the NFPA Standards Council approved the request
26、and the devel-opment of the standard was assigned to the NFPATechnical Committee on Industrial and MedicalGases (IMGAS). The IMGAS Committee established a task force on ethylene oxide, which devel-oped a draft standard that was made available for public review. Notice of its availability waspublishe
27、d in the December 1993/January 1994 edition of Fire News with a public proposal closingdate of January 21, 1994. The IMGAS Committee reviewed the proposals, and the Committeesreport was published in the 1995 Annual Meeting Report on Proposals. Further revisions werepublished in the 1995 Annual Meeti
28、ng Report on Comments.The 2002 edition contained requirements in Chapter 11 that addressed the use of oxidiz-ing emission control devices. These requirements were based on the recommendations of aNIOSH report generated after several incidents occurred that involved oxidizing emissioncontrol device o
29、perations.The 2002 edition was also revised to conform to the new Manual of Style for NFPATechnicalDocuments requirements.The 2007 edition includes the following changes: Elimination of the concept of special rooms to achieve consistency with NFPA 5000,Building Construction and Safety Code Addition
