Improving workplace Electrical Safety through Self-Assessment

Evaluation of Operational Risk in Power Substations and Its Rational Reduction on the Basis of Multicriteria Allocating Resources

“…Step (7) Preparation of a questionnaire covering the questions and a linguistic scale related to each criterion or sub-criterion. This questionnaire also considers the insertion of the s groups of components defined by the experts.…”

“…Under step (7), the questionnaire is prepared, considering the linguistic scale for each criterion or sub-criterion, defined by the experts. The use of the questionnaire, by step (8), permits one to evaluate the operational risks.…”

“…However, the improper use of electricity can result in injury to workers, including fatalities, and damage to electrical equipment, which causes production losses [1]- [6]. In addition, expenses with lawsuits and fines imposed by inspection agencies can be generated [7]. The decrease in the frequency of accidents of electrical origin compared to other types of risks may lead to a misconception that the electrical hazard management of electrical risks is under control [6], [8].…”

“…Although these accidents are rare when they do occur, they are usually serious and, can lead to fatal outcomes [3]. Considering this, the implementation of qualified management to reduce the risks involved in the process of operating power substations has become necessary in the activities of companies, which realize the corresponding management [6], [7]. The complexity of carrying out a risk assessment is a major challenge for these companies [9].…”

“…The determination of the most critical substations in terms of operational safety is necessary, for the rational use of limited financial resources. However, decisions on allocating available resources between the substations are usually made empirically, without using convincing methods [7].…”
