This article discusses the fire-retardant treatment of wooden structures with fire-retardant compositions with different characteristics of physical and chemical properties, and also determines their effect on the smoke-forming ability in accordance with the requirements of GOST 12.1.044-2018. "Occupational safety standards system. Fire and explosion hazard of substances and materials. Nomenclature of indicators and methods of their determination." Based on the laboratory studies, the behavior of different types of wood treated with fire retardant compositions when exposed to a source of ignition was established and an arcing coefficient was obtained under the combustion and smoldering modes of samples. It is worth noting that today wood is a universal building material and is actively used in construction, then for manufacturers of wooden structures, it is important to pay special attention to the protection of wood, as well as its behavior in case of fire. Treatment of wooden structures with fire retardant compounds is one of the ways to increase their resistance to fire and reduce the speed of flame propagation over the surface, and in some cases to prevent ignition of the treated material. High-quality processing of wooden structures will help to gain time for evacuating people and extinguishing a fire. However, it is important to remember that treatment with a fire retardant does not make wooden structures completely incombustible. It only slows down the combustion process and increases the fire resistance rating
