AbstractUsing 16 observers, the smoke densities required to reduce the visibility of each of 13 exit signs to threshold limits of detectability and readability were determined at both low and high ambient illuminations. Supported by known properties of smoke and the human visual system, some conclusions can be drawn from these data about the factors that influence exit sign visibility through smoke.
