Occupational Health and Safety (OHS), represent a very wide field of interdisciplinarity and multidisciplinarity in the following domains: technical, medical, military and security, because of the multiple of sources of elements of instability (risks, dangers, threats) to the workers, in order to discover the best optimal methods, actions of prevention and protection and ensuring the workplace's working in maximum safety conditions, without disturbing the industry and the national economy's wellbeing. The most effective way to protect the workesr health and safety is to remove the generators of risks, supplied that a methodology is available to identify how to treat these generators of risks. The assessment is carried out using the National Research and Development Institute of Occupational Safety - NRDIOS Bucharest method, in order to establish the risk/safety levels in a quantitative manner, based on a systemic analysis and on the assessment of risks of accidents and professional diseases. The role of OHS for power substation high voltage (critical power infrastructures) is to generate the national economy electricity, well-being, and safety work and health environment, workers and workplaces secured, and security of industrial and power process, in order to optimally operate the national economy and ensure energy security.

In order to ensure energy security the state must ensure access to electricity to all domestic and industrial consumers, which are made through power substations, which are very dangerous workplaces by the fact that the voltage are very high. For this reson role of Occupational Health and Safety (OHS) is to ensure secure workplaces in an ergonomic and healthy working environment for personnel. In many unfortunate cases, OHS activity is subordinate to production or service activity and risk assessments and audits are also made formally by non-specialized personnel, leading to undesirable events with an unstable effect, and the need for auditing with legal and other provisions is intended to verify compliance with OHS rules and principles and to limit or stop work accidents. This paper addresses the verification of OHS, by "INCDPM Bucharest method" - Auditing of conformity with legal and other provisions" - to an 400/220/110/20 kV power substation, for the purpose of verifying knowledge and conformity with legal and other provisions at the workplaces level and assessing the efficiency or failure of the OHS management system of the analyzed economic entity management, and after implementation it will serve as a tool to verify the functioning of the system. The auditing of the OHS shows that the power substation under consideration has an overall level of security close to maximum and a low overall risk level, which means that OHS rules are met and the auditing has had a positive effect.

The most effective way to ensure safety and protect the health of workers at work is to eliminate sources of danger. It is an action whose effects are maximal if carried out in the design and construction of work systems, but which is also beneficial afterwards, but with one condition: a methodology is in place to allow analysis, identification and determination of the treatment of these sources. The development of theory and applications in the field of systems security has provided a scientific basis and useful tools for the work of preventing professional risks. All methods designed to achieve system security have been taken over and adapted to determine with their help the possibilities of protecting the safety and health of workers. The development, implementation and promotion of an integrated, proactive approach to OSH management in high and very high voltage power substations has long been supported by policies and practices established at international, european and national level, including strategies, legal provisions, standards, guidelines, programs and campaigns initiated and undertaken by various stakeholders, such as international organizations, EU bodies, governments, trade unions and employers asociations, labor inspectorates and insurance institutions.

In recent decades, as a consequence of accelerated economic development, the issue of industrial and occupational risks, as well as the degree of diversification of real risks, have become increasingly important. The experience gained with accidents at work, damage and other categories of undesirable events highlights the need to understand and control risks "upstream", i.e. before the accident occurs. At the same time, awareness of populations at risk has resulted in a significant decrease in the risk acceptability threshold. In response to these social phenomena, public institutions, economic agents in the industry, researchers in the disciplines involved have proposed methods of risk forecasting, aimed at developing prevention and protection systems that improve the risk management process. Prevention of occupational risks is the only way to improve the safety and health conditions of the participants in the work process, as well as a reliable source for reducing costs, increasing labor productivity, quality of production and, finally, quality of social life. Risk management facilitates a structured and systematic approach to decision-making. The value and strength of the managerial approach to risk lies in the fact that it combines various valuation and consultation techniques, uniting them into an ensemble that gives consistency to the decision-making process. Risk management gives any organization the ability to better understand how operations are carried out and the ability to respond more effectively to changes in internal and external circumstances.
