Methodology for Assessing the Degree of Occupational Safety Specific to Hydrotechnical Construction Activities, in Order to Increase Their Sustainability

The effectiveness of the audit is conditioned by the systematic nature of the analyses and their periodicity. In this respect, the work of internal auditors must be coherent, continuous, and professional. These conditions can be met only if the activity is organized as a permanent system, which has its objectives and has resources (human, material, and financial), as well as adequate tools (audit method) corresponding to the activities carried out within the hydro-construction companies. The methodology for assessing the occupational safety status specific to companies in the field of hydrotechnical constructions was tested at the economic operators within SC HIDROCONSTRUCȚIA SA Bucharest. Thus, from the observation made based on the two calculation formulas’ application, it can be appreciated that the weighted amount more clearly and objectively reflects the existence of problems in achieving safety and health at work, thus constituting the result of a cautious approach, as opposed to the arithmetic mean formula, which leads to a result that tends to overestimate the value of the assessment. Additionally, the security risk determination in the field of occupational security at the economic operators was performed, according to the procedure of applying the method, based on the Gumbel probability function associated with insecurity, and the accuracy of various estimates on risk predictors was ensured by using the Kolmogorov–Smirnov statistical verification test in order to determine the confidence interval of the forecast results.
