Оцінка захисної ефективності фільтрувальних респіраторів при виборі й експлуатації

Abstract

The influence of errors and inconsistencies on the protective effectiveness of filter respirators during the process of their selection and operation, which is due to the need to assess occupational risks in the selection of filter respirators. The method of functional resonance analysis of the study was used to model the development of different scenarios through the description of the functions of the process of selection and operation of respiratory protection, which will lead to deterioration of workers' protection based on the time of operation, availability of necessary resources and appropriate level of control. The main functions in the selection and operation of personal respiratory protection, which depend on the analysis of working conditions, justification for the choice of personal respiratory protection, checking the adequacy and features of the operation of filter respirators based on input data, operating time of possible prerequisites, required resources and appropriate level control. To describe the variability of functions, it is proposed to consider four scenarios based on their timely and accurate implementation, which allowed to present possible errors in the selection and operation of filter respirators and their consequences for effective protection of the worker given the development of several possible positive and negative results. implementation. Recommendations have been developed to reduce errors in the selection and operation of filter respirators, which is extremely important and necessary to maintain the appropriate level of protection of users throughout the specified period of operation by strengthening control over their protective properties at each stage of use.
