The concentration of asbestos fibres during buildings exploitation analysis of concentration variability

Vol. 22, no. 1

art. no. e6, 2022

The goal of the research was to determine of average asbestos dust values in different types of buildings and possible deviations from these values, when taking measurements in different rooms of the same building. Variability of fibres concentration was analyzed over short periods of time in different places of tested building. The study included various types of buildings containing asbestos, typical for Central and Eastern European countries with different construction. An analysis was made of the reasons for the diversity of dust concentrations ranging from < 300 to 16,000 fibres/m3 in connection with the building structure, asbestos location, degree of damage and intensity of building exploitation. Properly operated residential buildings containing asbestos inside outer sandwich walls features low concentration of dust < 300–400 f/m3. Novelty: Buildings not yet described by the literature were examined, as well as so-called emergency situations not related to the correct proceedings. This knowledge is necessary for the selection of technology in dismantling works and whether it is appropriate to remove asbestos from a given structure.
