A contingency beginning at power facility can result into emergency mode of operation. Amount of fires at power facilities reduces, while direct damage increases. Overall material loss at power facilities mostly forms by large fires consequences. As well indirect damage caused by induced closedown of power facilities can also have social character expressed in large part of population vital abnormality. Fire consequences minimization at power facility should be gained by fire fighting timeliness. Along with fire fighting start time minimization continuity of fire fighting from starting fire fighting agent supply up to fire suppression is fundamental. It implies fire fighting forces and equipment concentration in good supply for fire isolation in size it gained by the time fire fighting initiates. The largest complexity in fire fighting at power facilities is smoke screening of burning and related areas. Limiting factor of fire fighter's residence time in conditions of dangerous fire factors is protective equipment protective power time. It's naturally that it must exceed fire fighting time. Figuring measures of fire fighters at power facilities continued supplying should be conducted as protective power time of protective equipment against dangerous fire factors is less then fire fighting time. Demonstrative fact is that use of respiratory protection equipment increases against the background of reducing number of fires at power facilities. Ensuring fire fighting at power facilities has feature of necessity for power facilities survival and resulting necessity for personnel work capability in case of fire. Therefore timeliness of power facilities fire fighting is possible to achieve by improvement of following directions: 1) providing visibility improvement and reducing exposure to smoke in fire condition of power facilities; 2) fire fighter's life support and operability assurance at power facilities; 3) developing protection methods and protective equipment from fire hazards for fire fighters at power facilities; 4) advancing fire fighter's operational and physical specifications in providing fire fighting at power facilities.
