Evaluation of Extended Coverage (EC) Sprinklers for Nonstorage Applications
Track(s): Fire Protection Engineering, Research

Jeffrey Newman, FM Global

Audio Sample:




During this session, you will examine the results and analysis of a study to assess whether "extended coverage" sprinklers could provide protection benefits comparable to those of standard sprinklers for non-storage applications (which are limited to small, scattered amounts of in-process storage). A series of large-scale sprinklered fire tests, performed with upright extended coverage (EC) sprinklers, resulted in demand areas no greater than those from standard sprinklers. Protection requirements for the EC sprinklers with the larger discharge coefficients were substantially less than for those for standard sprinklers. The results should also be generally applicable to pendent EC sprinklers due to the improved fire plume penetration of pendent versus upright sprinklers.

Jeffrey Newman is an AVP and Principal Engineer at FM Global and currently the program manager for strategic smoke damage research. He has specialized in the characterization of fire environments including modeling, material flammability, fire testing and fire detection. Jeff has published numerous papers on fire-related problems, such as mine fire hazards, burning characteristics of materials, flame propagation, fire calorimetry and flame heights, and the quantification and prediction of smoke properties.
