Diagram showing how outgoing heat from a fire is absorbed by a body (a). The outgoing radiative heat is absorbed onto the surface only and does not penetrate. Images of the setup of the black cards relative to an experimental fire (b) and a representative thermal image (c) demonstrating how the outgoing heat from the fires was measured using the thermal imaging camera and software
