Annually on the suppression of forest fires hun-dreds of experts of forest protection participate. Theoretical and experimental studying of influence of negative factors of forest fires on firefighters at various distances from an edge of the center of burning will allow developing the main requirements to the means of their protection. Thus it is neces-sary to define dangerous factors influencing forest firefighters to take temperature to a surface of their clothes at various distances from an edge of forest fire, and also to investigate structure of products of pyrolysis. At suppression of forest fires when fire covers crowns, the person is influenced by temper-ature over 100 degrees Centigrade and concentra-tion of carbon monoxide exceeds maximum per-missible values. The most toxic component of the volatiles formed at pyrolysis of forest combustible materials is carbon monoxide. The authors carried out studying of impact of dangerous factors of the forest fire on a human body working at a fire edge at main types of forest fire works. On the basis of the conducted researches the temperature of the surface of clothes of the forest firefighter in a work- ing zone was determined. Also measurements of the maintenance of concentration of carbon monox-ide in a burning zone at various distances from a flame were carried out. As a result of the conducted researches values of temperature and concentra-tion of carbon monoxide in a working zone of the forest firefighter were received. Mathematical de-pendencies of change of its contents at various distances from a fire edge were defined. These data allow developing the main requirements to means of protection of forest firefighters, to in-crease safety and efficiency of their work.
