Evacuation calculation by the fire + evacuation plans

The prominent feature of modern building is increase in quantity of buildings with mass stay of people. It is possible to carry covered cultural-sports complexes, cinemas, clubs, shops, industrial buildings to their number etc. Fires in such premises are quite often accompanied with traumas and destruction of people. First of all it concerns to the fast-flamed fires representing real danger to the person already in a few minutes after their occurrence and different intensive influence on people of dangerous factors of a fire. The most reliable way of safety of people in such conditions is timely evacuation from a premise in which there was a fire.

According to standard documents of the Russian Federation, each object should have such space-planning and workmanship that evacuation of people from a premise has been finished till the moment of danger fire factors achievement of maximum permissible values. In this connection the quantity, the sizes and a design of evacuation ways and exits are defined depending on necessary time of evacuation, i.e. time during which people should leave a premise, without being exposed life-threatening and health to fire influence.

According to the work recommendations necessary time of evacuation calculates as product of critical for the person fire duration to a safety coefficient. Time after which there is a dangerous situation owing to achievement by one of danger fire factors maximum permissible value for the person is meant critical duration of a fire. Thus it is supposed that each dangerous factor influences the person irrespective of others as complex influence of various qualitative time various qualitative and quantitative combinations of fire, characteristic for an initial stage of development of a fire, it is not obviously possible to estimate now. The safety factor considers a possible error at the task in view decision. It is equal to 0.8.

Our organization renders services in evacuation calculation; the cost of evacuation calculation depends on workload (area, number of storeys, complexity of architecture).

Data on necessary time of evacuation is also the initial information for calculation of level of safety of people at fires in buildings. Incorrect definition of necessary time of evacuation can lead to acceptance of wrong design decisions and increase in cost of buildings or to insufficient safety of people in case of fire occurrence.

Thus, for definition of necessary time of evacuation of people from a premise it is necessary to know dynamics of fire in a zone of stay of people (a working zone) and maximum permissible values for the person of each of them. To number danger fire factors which represent the greatest danger to people indoors to an initial stage of a fast-flamed fire, can be carried: the raised temperature of environment; a smoke leading to loss of visibility; toxic burning products; the lowered concentration of oxygen.

At the evacuation calculation EVACUATION PLANS FOR ALL PREMISES will be given FREE OF CHARGE.
