Electrical safety groups: who should be assigned which group?

III group

Electrical and electrical engineering personnel. Assigned to employees involved in the operation of electrical equipment, it gives the right to independently install equipment and connect its electrical networks, as well as the right to inspect or service electrical installations with voltages up to 1000 V.

Example of positions:

• electrician
• electrician
• auto electrician
• repairman
• electric arc furnace operator
• electrician
• electromechanic

Group V

Electrical technical personnel, including administrative and technical personnel. Management of the organization, specialists, engineers and technical workers. Employees organize, manage and carry out work at workplaces and in production units. They also carry out control and technical supervision of work in electrical installations up to and above 1000 V and at power industry enterprises.

Example of positions:

• Chief Power Engineer
• energy drink
• occupational safety specialist in electrical installations up to and above 1000 V at power industry enterprises
• inspectors of GIT and Rostechnadzor who have access to control electrical installations up to and above 1000 V

Requirements for the presence of electrical safety groups

Electrical safety groups, starting from III and above, can only be assigned to workers who have reached the age of 18.

For occupational safety specialists, as a rule, they are assigned group IV in electrical safety with the right to inspect electrical installations (clause 6 of the note to Appendix 1 of the Rules on labor protection during the operation of electrical installations, approved by Order of the Ministry of Labor dated July 24, 2013 No. 328n).

A group is also assigned to the head of the organization if the manager personally inspects electrical installations and is involved in operation, installation and repair. Otherwise, Group I will be sufficient for the leader. Heads of structural units who have electrical personnel subordinate to them must be assigned access groups no lower than those of their subordinates. Employees from among the administrative and technical personnel with a tolerance group of at least IV or V (for electrical installations up to and above 1000 V) are appointed as responsible managers of work in electrical installations.

Electrical safety group: requirements for personnel

Electrical safety group I Electrical safety group II Electrical safety group III Electrical safety group IV Electrical safety group V It should be borne in mind that servicing existing electrical installations, as well as carrying out operational switching in them, organizing and performing repair, installation, adjustment work, testing, measurements and diagnostics must be carried out by electrical personnel with the appropriate electrical safety group.

At the same time, persons working in electrical installations must have a certain amount of knowledge, skills and abilities that will allow them to carry out high-quality measures for the safe operation and maintenance of machines, devices, lines and auxiliary equipment included in electrical installations.

However, it is necessary to take into account that, as stated in sub. 4.2.2 clause 4.2 of the technical code of established practice “Safety rules for the operation of electrical installations” (TKP 427-2012 (02230), approved by order of the Ministry of Energy of the Republic of Belarus dated November 28, 2012 No. 228 “On approval and enforcement of the technical code established practice", which came into force on March 1, 2013, with the amendment introduced by Order of the Ministry of Energy dated November 23, 2021 No. 307 and put into effect on January 1, 2021, the requirements for assigning electrical safety groups to workers established in Appendix B to this TCH are minimal and can be supplemented by the employer’s decision.

Therefore, based on the above, we can conclude that the basic requirements regarding the assignment of electrical safety groups are defined in TKP 427-2012. At the same time, when testing personnel knowledge on electrical safety issues, in addition to the above-mentioned TKP, in particular, it is also necessary to be guided by:

• Instructions on the procedure for training, internship, instruction and testing the knowledge of workers on labor protection issues, approved by Resolution of the Ministry of Labor and Social Protection of the Republic of Belarus dated November 28, 2008 No. 175;

Assignment of II-V electrical safety groups

The electrical safety group for electrical personnel in an organization is assigned by a commission. Applicants undergo preliminary training and take an exam according to developed training programs. The result of the certification (knowledge test) is recorded in a special journal.

Commission for testing the knowledge of electrical engineering personnel

A commission to test the knowledge of electrical engineering personnel of an enterprise is created by order of the manager. The commission consists of at least five people (clause 1.4.30 of the PTEEP). In this case, the chairman and at least two members of the commission must pass a knowledge test at Rostechnadzor.

The person responsible for the electrical facilities (for example, the chief power engineer) is usually appointed as the chairman of the commission. As we wrote above, the chairman must pass a knowledge test in the Rostechnadzor commission and have an electrical safety group of at least IV - for organizations with electrical installations up to 1000 V or V electrical safety group for electrical installations up to and above 1000 V. At the same time, the chairman and his deputy the access group must be no lower than the one being certified. As a rule, members of the commission are a labor protection specialist, technical managers, and leading specialists (chief mechanic, chief engineer). The commission must always consist of an odd number of members. Even if the chairman is absent during the knowledge test (he is replaced by a deputy) or one of the members, a separate order is not required. Sometimes it is advisable for structural divisions to create their own separate commissions to test the knowledge of electrical personnel, the members of which undergo a knowledge test in the central commission of their organization (clause 1.4.32 of PTEEP).

Study programs and exam papers

For pre-certification training of electrical engineering personnel, we offer you samples of training programs and a list of exam papers.

Logbook for testing knowledge of operating rules in electrical installations

After the creation of a commission on electrical safety and the development of training programs and examination cards for assigning groups II-V electrical safety to electrical personnel in the organization, it will be necessary to create a special journal to record the testing of knowledge of the rules of work in electrical installations. The form of the journal is given in Appendix No. 6 of the Rules on labor protection during the operation of electrical installations (Order of the Ministry of Labor No. 328n dated July 24, 2013).

In electric power industry organizations, during the exam, the commission draws up a protocol for testing knowledge of the rules of work in electrical installations (Appendix No. 4 to the Rules).

Electrical safety clearance groups, assignment procedure

Do we think about who we trust with our lives? The driver of the bus or taxi in which we rode yesterday, the pilot of the plane, the doctor who prescribes us treatment - our life and its quality in one way or another depend on these people.

Electrical installations are a serious matter, so working with them requires both theoretical and practical knowledge. And if grades in a certificate or reputation can serve as a guarantor of theoretical knowledge, then practical abilities are confirmed by an assigned electrical safety group. What are these groups? How to get them? Who needs them? Is there responsibility for working without a group? Let's figure it out.

Let's start with the basics - what is an electrical safety group? To find out, let’s open TKP 181-2009, which contains a manual for the technical operation of electrical installations. From paragraph 4.2.30 it becomes clear that the electrical safety group is a personal document confirming that its owner has knowledge of the relevant regulations, technical regulations, technical regulations and other acts and codes on electrical installations.

Let's take a look at TKP 427-2012, dedicated to safety precautions when working in electrical installations, and look at Appendix B. In addition to knowledge of technical regulatory documentation, the worker receiving the group must understand the electrical circuits of installations, process technology and understand how to provide first aid to victims of exposure to current. According to the same TCP, to assess electrical safety knowledge, there are 5 groups, where I corresponds to the minimum required set of knowledge and skills, and V gives the right to work with high-voltage installations and be responsible for electrical work. Let's consider what requirements are presented for assigning a particular group.

Group I - it is required to distinguish between the concepts of current and voltage, to be aware of the danger of current, to have basic first aid skills - turn off the switch, safely pull the victim away from the exposed wire. Group I does not allow you to work in electrical panels; it only formally allows you to work with a computer, printer, electric broom, and so on. To get Group I, all you need to do is listen to the instructions.

Group II requires knowledge of how an electrical installation works; to obtain it, you must be well versed in safety precautions, have a clear understanding of the dangers of electricity, and be able to provide first aid. Starting from the second group, you can work, for example, as an elevator operator, crane operator, electrician, or electric welder. Only groups I and II can be obtained by a minor.

Group III includes, in addition to the requirements for the previous groups, general knowledge of electrical engineering, the ability to maintain an electrical installation, and rules for the use of electrical protective equipment. In addition, to obtain the third group, social skills are also needed: the ability to give instructions, organize work, and monitor personnel working in electrical installations. With the third group, you can work as an electromechanic and perform some work in installations above 1000 V, for example, mowing grass and removing snow from switchgears.

IV group. Knowledge of electrical engineering is required at least at the vocational school level, detailed knowledge about the effects of electricity on the body, fire safety, safety precautions, you need to be able to provide first aid to victims at the scene of an accident. With the fourth group, you can teach staff safety precautions and first aid rules. Personnel with this group can be appointed responsible for the execution of work. Those supervising the work must have group IV, which also gives more opportunities to work in installations above 1000 V.

Group V speaks for itself. Workers with the fifth group are allowed to work in installations above 1000 V and be work managers. To obtain each subsequent group, depending on the level of education, you must work in the previous group for the time specified in Appendix B of TCP 427. You will not be able to immediately obtain the fifth group. After receiving the certificate, you must periodically confirm the group in accordance with TCH 181. If you fail within one month, you can try to get the group again. If the abilities do not correspond to the work performed or if it is impossible to confirm the group, the employee is suspended from work in accordance with the law.

You can get an electrical safety group in two ways, each of which involves communicating with a commission of 3 people or more: either at your enterprise for free, or at Energonadzor for a fee.

As you can see, the electrical safety group is not only broad powers, but also high responsibility for oneself and others, which is the reason for the procedure described above for obtaining it. Specialists are assigned groups IV and V, so we will be happy to help you carry out electrical measurements, whether in an office or a substation.
