OPTIMIZATION OF SYSTEM OF FIRE-PREVENTION PROTECTION OF OBJECT BY MEANS OF THE DIFFERENTIATED ASSESSMENT OF PROBABILITY OF EMERGENCE OF A FIRE

The method of calculation of risk existing today for public buildings considers very limited circle of technical solutions. Space-planning and constructive decisions are considered only when forecasting dangerous factors of a fire. In this regard, introduction of similar actions when carrying out calculation isn't taken into account. Besides, the existing technique contains limited amount of information about probability of emergence of a fire on various objects. Thus characteristics of concrete object aren't taken into account. In this work the way of definition of probability of emergence of a fire in each concrete room of the building depending on its area and fire danger is offered. The simplified way of an assessment of efficiency of application of fire-prevention barriers is considered. The offered way allowed to estimate need of the device of fire-prevention barriers or other fire-prevention actions for the concrete room, and also to determine the size of fire risk for the building as a whole. Application of this way provides opportunity to build the optimum fire protection system of object.
