| Abstract |
Measurement of atmospheric CO concentrations and microclimatic conditions in a modern foundry showed that the mean CO concentration for the whole shift significantly exceeded the maximum allowable concentration. During the warm season, the climatic conditions deteriorate, and the CO concentrations are 4 times higher than the threshold level, increasing on average 50-100% in comparison with the transient period - depending on the atmospheric conditions. It is proposed that the natural ventilation should be supplemented by local exhaust ventilation at the pollution source, and ventilation apertures should be provided to ensure a fresh-air supply to the areas of the foundry distant from the exterior walls. The dynamics of CO concentration fluctuations justify the requirement that measurements be taken regularly for at least 5h per shift. |
