Abstract
Introduction. To adequately protect workers from gaseous air pollution using air purifying respiratory protective devices (RPD), it is necessary to periodically replace filters.
The aim of the study was the analyze the methods of monitoring the performance of workers’ RPD.
Materials and methods. Nowadays the subjective reaction of smell to an increase in the concentration of gas in the mask is widely used. This practice is compared with the available scientific information on the subjective ability of humans to detect gases.
Results. The requirements for filter replacement in the legislation of foreign countries are analyzed. It has been established that for most hazardous substances there is no available information on the thresholds of odor (irritant) perception, and the available data show a high probability of exceeding the odor perception thresholds over the maximum permissible concentrations of hazardous substances in the working area. for getting used to it, distraction of attention, low individual sensitivity, etc. The existing approach in Russia leads to the belated replacement of part of the filters and, as a consequence, to the deterioration of the professional health of workers.
Conclusion. Recommendations are formulated on the measures, the implementation of which is necessary to improve the protection of personnel used air purifying RPD.
