MODELING OF FIRE DYNAMICS WHEN MAKING JUDICIAL NORMATIVE FIRE-TECHNICAL EXPERTISE

 

Abstract. It is often necessary to assess the parameters of fire development taking into account the influence of fire protection systems by making the regulatory fire-technical expertise. It may also be necessary to carry out an expert examination of the technical solutions adopted at the site for their compliance with fire safety requirements. These practical studies, in particular, are necessary to analyse the consequences of fire safety violations and establish causal links between violations of requirements and the consequences of fire, both past and theoretically possible.

A modern way to estimate fire parameters is by field modeling. Field modeling of fire dynamics can be used to answer questions in two expert situations: after fire and before fire (in particular, within the framework of supervisory measures). When making fire-technical expertise on the fire occurred, the expert needs to restore the pre-fire situation and model the real fire dynamics taking into account the established fire information contained in the case file. In a situation before a fire, the expert needs to model a potentially possible fire under the most unfavourable conditions.

In accordance with fire safety requirements, each object of protection must have a fire safety system aimed at preventing fire, ensuring the safety of people and property in case of fire. Compliance of design values and characteristics of the building or structure with safety requirements shall be justified by calculations or tests performed according to certified technique.

On the basis of the analysis of the regulatory framework and the formulated groups of regulatory questions there have been developed the procedure of the expert‘s actions and the algorithm for simulating fire dynamics when answering questions related to automatic fire alarm. The impact of input data on the possibility of forming categorical or probabilistic outputs was evaluated. The proposed detailed algorithm of field simulation of fire dynamics during the regulatory fire-technical examination is drawn up taking into account possible calculated errors and obtaining ambiguous results.
