METROLOGICAL PROVISION OF WORKPLACE CERTIFICATION ACCORDING TO WORKING CONDITIONS

The purpose of the study is to determine the requirements for research methods, measurements with the help of FTA of harmful and dangerous production factors, which will allow to ensure a high level of attestation of workplaces according to working conditions. The task of the research includes consideration of issues related to ensuring the unity of measurements in the field of labor safety, compliance of metrological activity in the specified field with the requirements of current legislation in the field of metrology. The task of the research is also to identify problems related to the methodological support of laboratory research in the field of occupational safety, the absence of metrological requirements for laboratory research methods, metrological confirmation of FTAs, which are intended to perform workplace attestation. Currently, there are separate scientific works on the development of standard procedures for measuring dangerous or harmful factors of the production environment, there is an established norm for any harmful parameter, but there is no national order in the methodology of measuring each parameter. Individual measurement methods do not have the status of a normative legal act. Thus, at present, there are no legal acts regulating mandatory methods of measuring the parameters of harmful factors of the production environment and the labor process during workplace attestation. Analyzing regulatory documents, it can be concluded that from the main documents establishing the standardization of some factors of the working environment, the accuracy of measurements was established only for microclimate parameters. It should be concluded that in the field of labor protection, the state of ensuring the unity of measurements cannot be recognized as satisfactory. Summing up, we can come to the disappointing conclusion that for a reliable assessment of working conditions in workplaces, it is necessary to follow the methods of measurement and calculation of measurement uncertainty, which, unfortunately, are not always set out in mandatory documents.
