The limited resources of fossil fuels and the changing situation in economy and politics, lead to a higher interest in hydrogen as a fuel, with a wide range of use. It is currently used in the petroleum and automotive industries (in the latter to drive vehicle engines), and to heat households and provide them with electricity (fuel cells). Hydrogen is, at the moment, obtained from natural power resources, i.e. natural gas, petroleum, coal and water electrolysis. The methods most often used to obtain hydrogen are: steam reforming, coal gasification, partial oxidation of refinery residues and electrolytic water decomposition. Hydrogen is a relatively hazardous gas. Consequently, its manufacture, storing and transport pose a crucial problem. In case of a leakage it can be expected to form a combustible mixture more quickly than other fuels due to its higher diffusivity and rapid mixing with air. The paper presents an analysis of the effects of ignition of hydrogen leaking from untight installations. Calculations of the radiative heat flux value of burning hydrogen in the function of the outflow are presented. The change in the heat radiation in the function of distance from the leakage is determined. Potential heat radiation effects on people within its reach are assessed.
