Abstract
The author undertakes to systematise and compare various types of losses of the technical and functional properties of equipment related to diving with other areas of human activity in which technical equipment is used. The basis for this is the extensive literature describing, inter alia, the issues of wear and tear of machine parts, their damage, failures, etc. a phenomena occurring in the “life” of virtually every technical object. The specificity of diving techniques makes it a relatively little analysed segment of activity from the perspective of exploitation. Based on the analysis of publications and own materials, the author has reviewed and matched them in terms of similarity of loss of technical and functional properties of various elements of diving technology in relation to the divisions and criteria used in generally understood utilisation.
