Appropriate works aimed at use of “Fire Dynamics Simulator” (FDS) software for the computer simulation of fire spread across façade system surfaces and comparison of experimental and calculated data were analyzed. A number of full-scale fire tests were conducted of the external wall constructions fit with façade heat insulation and finished with rendering for fire spread while using 150 mm wide slabs fabricated of expanded polystyrene of “PSB-S-25” type as heat insulating material. Computer simulation of fire dynamics using FDS numeric tool was implemented and results obtained were compared with experimental data in order to check possibility of use of appropriate software for the reproduction of real conditions of fires at dwelling houses.

Thefire hazard of herbaceous plants causes the occurrence and spread of fires in herbaceousecosystems. Various indicators, in particular the humidity of the combustible material, the self-ignition temperature, etc., can estimate it. These indicators depend on the type of plants and thenatural conditions that determine the properties of the combustible materials.The goal of theresearch is to determine the fire hazard indicators of five the most widespread herbaceous plants inUkrainian ecosystems (Festuca arundinacea, Festuca pratensis, Elymus repens, Phleum pretenseandTrifolium arvense) and to substantiate these indicators due to results of thermogravimetric analysisand values of absolute humidity and self-ignition temperature. Within 5 days, the absolutehumidity of the samples as well as the self-ignition temperature were determined by weightmethod and using the ОТР testing device. Complex thermal analysis of samples was also performusing a Q-1500D derivatograph. The results of the research show that absolute humidity and self-ignition temperature of certain types of plants specify differences in their fire-fighting properties.According to the results of complex thermal analysis for each plant species, three stages occur atdifferent temperatures: evaporation of free and bound water, self-ignition of samples andcombustion of carbonized residue. The maximum exothermic effect for each plant wascharacterized by different value of temperature, as well as ash residue, which impedes thecombustion process.
