Recently, expert institutions have begun to receive more and more procedural documents on the appointment of construction and technical types of examinations for the solution of which concerns issues to determine the quality of the work carried out on the fire protection of wooden structural elements. And this is not surprising, given the fact that considerable amount of money is spent on this type of work based on the analysis of reporting documentation, and the quality of such work as practice shows does not always meet the requirements of regulatory documents. The main tasks that constructive fire protection performs are a significant increase in the fire resistance of a building material, prevention of its deformation, and also an obstacle to the further spread of the resulting fire. All this will help to preserve the safety of the building quickly and in a timely manner, as well as to carry out a full evacuation without any loss.
The article is devoted to the consideration of the main methods that can be used to determine the quality of work performed on the fire retardant treatment of wood with DSA-1 and DSA-2 solutions. In turn, the effectiveness of each method was tested in practice by the author of this article at various research sites, in turn, based on their practical application, it is possible to conclude that these methods are quite effective and can be fully used by forensic experts in conducting such studies.
