The effect of the fume gases, produced when the insulation of chlorine-free cables burns, on the catalytic activity of hydrophobic low-temperature and hydrophilic high-temperature platinum catalysts of hydrogen oxidation, which are to be used in the ventilation-gas detritization system. The temperature regime for the combustion of cables in the presence of an oxygen deficiency is determined and the semiquantitative composition of the products formed is obtained. Upon exposure to the fume gas flow at room temperature the experimental samples of the catalysts were almost completely poisoned. At the initial temperature 473 K of a hydrophilic catalyst thermal activation of the catalyst occurs in the presence of fume gases.
