A three-dimensional mathematical model for calculating 
heat and mass transfer in propagation of hydrogen in a building that 
allows for gas exchange with the environment through an opening has 
been proposed. Based on numerical calculations performed by the proposed 
model, the author revealed certain features of the concentration fields 
of hydrogen in the case of its inflow at the floor level. It is shown 
that the dimensions and location of the explosion- and fire-hazardous 
zones change considerably during the process.
