Effective resolving issues met in exploitation of electrical equipment in explosion-proof execution is one of the most important items in maintenance process. This paper presents basic questions of exploitation of electrical equipment in explosion-proof execution in collation with some aspects of hazardous area documentation. Based on experiences obtained during the implementation Directives of European Parliament and the Council, mainly ATEX 137 in correlation with ATEX 95, WEEE and their transposition into polish law rules, the paper describes selected concerns of electrical equipment accessibility or some questions of detailed engineering, erection, installation and commissioning processes in interaction with maintenance process, expressed on example of the Main Production Unit of PKN ORLEN S.A., located in Plock. Correlated with mentioned directives, selected technical standards published by Polish Committee for Standardization are the background to present the effects, in aspects of maintenance of electrical equipment in explosion-proof execution, business efectiveness and care for safe, unpolluted environment.
