Assignment to a technical worker of a certain group regarding electrical safety is a prerequisite that allows him to obtain a permit for the possibility of self-maintenance of operating electrical installations. The stated requirement equally applies to persons who directly use equipment in their work, but are not related to electrical work. Electrical safety certification is also carried out for them.
Educated electricians by enterprises, institutions/organizations are divided into the following categories regarding the specifics of occupations:
- administrative and technical staff;
- operational staff;
- maintenance personnel;
- operational and maintenance personnel;
- technological staff of electrified production departments.
The administrative and technical workers include specialists and managers who are responsible for operational and maintenance, installation, various repair and adjustment actions in working devices, as well as having certain tolerance groups forelectrical safety.
The duties of the operational staff include conducting a quick service of the devices, which includes switching, inspection procedures, preparation of the workplace, granting permission to the craft, strict supervision.
