Subject: EPA issues rules on Halon
EPA's " Final Rule on the Protection of the Stratospheric Ozone: has been published in the March 18th, 1994 Federal Register. The section dealing with Fire Suppression and Explosion Protection (pp.13097-13110, 13137-13144) focuses on a discussion of potential substitutes for Halon 1211 and 1301 which have been proven to be " among the most ozone-depleting chemical in use today" and will be banned by international convention before the end of the century. Each substitute chemical or technique is discussed from the point of view of environmental impact and effectiveness in fire suppression. Although each of these chemicals or techniques will require evaluation as to their library, archival or museum applicability, the data provided by the Register and in NFPA Standard 2001 are useful starting points for such evaluation. **** Moderator's comments: The document is available via Gopher at the following URL: gopher://gopher.counterpoint.com:2002/0R0-953586-/ByDate/031894/031894/0318 I had hoped to make it available on CoOL, but it copyright to the electronic text is held by Counterpoint Publishing, who provide the above gopher. The "Final Rule..." also discusses substitutes for Ethylene Oxide(10\88 formula), pp. 13111-13112, which was used for the fumigation of books and archives in pressurized fumigation chambers in the recent past. Since the standards focuses on ozone-depletion avoidance rather than general safety, the use of pure EO is suggested as acceptable in this standard since it contains no fluorocarbons, but the standard also points out that EO is "toxic, carcinogenic and flammable." *** Conservation DistList Instance 8:5 Distributed: Friday, July 1, 1994 Message Id: cdl-8-5-001 ***Received on Monday, 27 June, 1994
