Title A review of the criteria for people exposure to radiant heat flux from fires
Bibliographic information Nov. 2008, Vol.159, No.1, p.61-71. Illus. 28 ref.
Abstract This article reviews the available literature on skin burns caused by radiant heat exposure. The associated thermal and spectral properties of human skin are discussed. The basis for the United States regulatory setting of 5kW/m2 for evaluating distances for the exposure of persons to radiant heat effects of large fires is discussed. An example calculation is provided to show the extent of reduction in the hazard distance to specified radiant heat flux from a fire when the spectral reflection and absorption properties of skin are considered, with and without the inclusion of the mitigating effects of clothing. The results indicate that hazard distances calculated including the reflective and band absorptive properties (in IR wavelength) of skin results in a reduction of between 30 and 50% in the hazard distances obtained using the current methodology.
