Abstract

Recently, the Committee responsible for NFPA 654 came up with two new consensus criteria for determining that a compartment is a dust explosion hazard: one aimed at mitigation of burn injuries, and the other for room/building collapse prevention. As described in Rodgers and Ural (2010), the criteria are based on maximum allowable airborne combustible dust mass. Both formulas rely on an empirical entrainment fraction, ηD, representing the fraction of dust accumulations that can become airborne during an accident. After much discussion, the Committee selected a value of ηD = 0.25 which offers the same level of protection NFPA 654-2006 does for typical occupancies, pending the outcome of this Research Foundation sponsored project.
