The influence of fire retardant on ignition of wooden materials by radiation of a relatively high intensity was experimentally investigated. The ignition process was visualized by using Schlieren method and recorded by a camera. The study was focused on the relation between ignition delay time and radiation intensity for treated and untreated materials. Pictures showing differences in development of ignition processes for different samples were used to evaluate ignition delay and mechanism of ignition process. Results show that ignition process proceeds in a different way for treated and untreated materials. It was proved that tested fire retardant acts as an absorbent of radiative energy by melting in the first stage and then by generating non-flammable gases.
