2nd electrical safety group, who is assigned

At any enterprise, employees performing work using electrical equipment must have a special permit that allows servicing it. To obtain it, you must pass qualifying exams for assignment of an electrical safety clearance group. Each group corresponds to the range of production tasks that an employee is allowed to perform when working with electrical equipment or electrical installations.

Maintenance of electrical equipment by an electric welder with 2nd tolerance group

The scope of tasks solved by personnel in each group is regulated by the Interindustry Rules for Labor Protection (Safety Rules) for the Operation of Electrical Installations.

According to these Rules, there are 5 electrical safety groups. Group numbers are arranged in accordance with the increasing complexity of the tasks being solved by employees. They take into account education and experience working with electrical equipment.

Attention! Workers who are not electrical personnel can be assigned only groups 1 and 2.

The first is assigned to non-electrical personnel after instructions have been completed by a specialist of group 3. After this, the assimilation of the material is checked using an oral survey of employees. During the briefing, issues of the negative impact of electric current on the human body are discussed, as well as the rules for providing first aid to the victim. The results of the knowledge test are recorded in a standard journal.

To whom is it assigned?

Group II on electrical safety in enterprises and other structures is necessary for persons working with power tools or equipment. In accordance with regulatory documents, it is necessary to conduct training and test knowledge of the following categories of employees:

1. If your work activity involves the use of power tools. For example, angle grinders, drills, hammer drills, screwdrivers and more.
2. Riggers, slingers or persons associated with the operation of lifting mechanisms.
3. When working on welding units.
4. Management team, if there are persons under management who need to be assigned to the second group. This includes immediate managers, safety engineers, and mechanics.

It is important to know that these categories of people do not have the right to repair the instrument and check its functionality.

Categories of electrical technical personnel

In the occupational safety rules, all personnel are divided into several categories and each has its own functions:

1. Administrative - technical. This includes persons supervising the work. Mainly the management team.
2. Operational. Employees whose activities are related to the maintenance and operational management of tools or installations operating on current.
3. Repair. These are workers who have the right to carry out repairs or maintenance, as well as carry out testing, installation and commissioning operations.
4. Operationally - repair. These personnel are provided with the ability to perform maintenance and repair work.
