The paper describes the experimental measurements concerning the formation of critical concentrations of methane in a closed space. Measurements were carried out in order to monitor the formation, propagation and distribution of methane-air mixture in a confined space. Experimental data are also used for verification of numerical simulations of methane distribution and formation of its local critical concentrations in a closed space. Within experiments, the spaces with low velocities of flow of flammable gas were primarily watching and the measurements provided information about local changes of methane concentration in time. During experiments more points could be monitored at the same time so compact description of flammable gas propagation through given space was obtained. Gained results will be used for choice of suitable mathematical model for numerical simulations.
