The state and prospects of improving the hygienic regulation of industrial general vibration

Abstract

Hygienic rationing is an integral part of national measures in the field of occupational safety and health of workers. The current norms of general industrial vibration, as is known, are not safe. This determines the urgency of improving the system of hygienic rationing of general vibration, which, despite the achievements of science and technology, the emergence of a new controlled vibration parameter — full vibration acceleration, the introduction of a risk-based approach to rationing, has remained virtually unchanged for almost four decades. The study aims to analyze domestic and international approaches to the assessment and normalization of general industrial vibration to justify the transition to a risk-oriented single-digit regulation of full vibration acceleration. The authors carried out an expert and analytical study, analyzed and compared the materials of domestic and foreign regulations, methodological documents and literary sources on various aspects of the problem of rationing general industrial vibration. Scientists have developed a new system for rationing the unfavorable factor of the production environment — general vibration, which establishes an integral standard for complete vibration acceleration, instead of differentiated rationing by vibration sources (transport, transport-technological, man-made) and directions of vibration action along the axes of the basocentric coordinate system (Z, X, Y). The new standard for full vibration acceleration is harmonized with ISO 2631 standard, Directive 2002/44/EC, standards adopted in foreign countries, and, according to calculations, can be approximately 0.56 m/s2 or 115 dB, which requires experimental studies to verify. The new risk-oriented system of rationing of the industrial general vibration will make it possible to objectify the assessment of workers' working conditions and, as a result, streamline and update the examination of the connection of the disease with the profession.
