Wilmington, Del., September 17, 2007
The National Fire Protection Association (NFPA) earlier this year rejected ROC 2001-61a, a proposal to increase the minimum design concentration requirements of clean fire extinguishing agents to extinguish fires involving energized electrical equipment (Class C fires).
As a result of this decision and the outcomes of subsequent committee votes on this matter, NFPA recently announced that it will issue the 2008 edition of NFPA Standard 2001 with guidelines from the current (2004) version, preserving existing industry standards for design concentrations for Class C fires.
Several companies, including DuPont Fire Extinguishants, opposed the recommendations in ROC 2001-61a and filed a Notice of Intent to Make a Motion (NITMAM) with NFPA to reject the proposal. DuPont’s position was that ROC 2001-61a, if passed, would have increased costs to the industry by more than 33 percent, while providing no meaningful improvement to safety. NFPA members conducted a floor vote in June, upholding the NITMAM. In July, NFPA’s Technical Committee on Gaseous Fire Extinguishing Systems was balloted on the issue. The outcome of the Committee’s vote was a recommendation to the NFPA Standards Council to revert to current (2004) edition text for minimum Class C design concentrations in the new (2008) edition of NFPA Standard 2001. The NFPA Standards Council accepted this default action to revert to current edition text, which, in this case, has the same effect as the rejection of ROC 2001-61a.
"The NFPA’s recent vote to maintain the current minimum Class C design concentration level ensures that clean agent fire extinguishants in this application will remain cost-effective and reliable," said Greg M. Rubin, global marketing and business manager, DuPont Fluorochemical Specialties. "Based on the latest studies and historical analysis, as well as the effectiveness of the existing design concentration in extinguishing Class C fires over the last 15 years, we believe that this decision is in the best interest of the industry and its customers, and we are pleased that we could help raise awareness about this issue among NFPA members, who supported our motion to reject ROC 2001-61a."
