Abstract
Occupational risk assessment is a prevention tool used to manage safety and health at work in the national economy sectors of activity.Within the operation and maintenance in underground electrical installations, several major risk factors are identified, mainly due to work equipment cumulated with risk factors generated by the work environment and workload.To highlight the working conditions and the technical requirements of the underground electrical installations, the activity carried out for 50 years was analyzed, taking into account the lifespan of the electrical installations. Also, the events and accidents at work, the assessments of the risk in the workplace was analysed and represents a synthesis of research studies carried out so far.The research highlights the role of safety measures aimed to ensure the safety and health of workers working in underground electrical installations, mainly about work equipment and the means of work against electrocution to efficiently manage occupational risks and reduce workplace accidents and occupational disease, as well as technical events in electrical installations.
Highlights
In the last years in the urban areas, the aim was to replace the overhead electric power distribution lines with the underground power lines (UPL)
The diagnosis of activity performed by operating and maintenance personnel was made by analysing the components of the work system and the technical-economic demands, in conjunction with the provisions of the legislation on safety and health at work and the technical regulations issued by the national authorities in the energy field
According to GD no.1091/2006, workplaces that use electrical installations and implicitly UPL must be arranged so that there is no danger of fire, explosion and workers are protected against electric shock by direct contact, indirect contact and step voltage. [1, 2]
Summary
In the last years in the urban areas, the aim was to replace the overhead electric power distribution lines with the underground power lines (UPL).
