Various samples of fire-retardant cloth have been examined in terms of their thermal performance nowadays. The undertaken samples are sequenced with ample of variation of their position to make a multi-layered fabric orientation. A numerical model has been developed in a finite difference approach using fully implicit scheme of time and space. The proposed orientations are exposed to a radiant heat exposure with very high intensity of heat flux. The temperature profiles throughout the human skin layers have been obtained using very popular Pennes Bioheat Transfer Equation. The severity of thermal damage has been calculated using Henrique’s Burn Integral Model at basal and dermal layer of human skin. It is concluded with a detailed discussion about the effectiveness of the different fabric orientations in firefighting applications according to their degree of thermal damage in human body.
