During the last three years, beginning just after the release of NFPA 86-1999, National Fire Protection Association (NFPA) technical committee members have been tabulating, collating and consolidating the three NFPA 86 standards (NFPA 86, 86C and 86D) into one new standard (NFPA 86-2003) that covers all areas of ovens and furnaces as well as special atmosphere furnaces and vacuum furnaces. The new standard was published in September and is available through NFPA's web site at www.nfpa.org.
The NFPA 86-2003 edition represents a consolidation of the three separate standards and a few changes. One specific change is the commonality that now exists between the definitions found in the three older standards. Because there is only one standard, definitions are common to all areas.
Editor's Note: Beginning in January, "Safety Zone" will cover specific changes to NFPA 86 that affect manufacturers who use heat in their processes.
