The procedure for assignment of group on electrical safety is determined according to User Safety Rules for Operating Electrical Equipment, approved by the Government of the Republic of Kazakhstan.

5. Persons allowed to performance of works to whom the additional (raised) requirements on safety of special works are imposed need to have the certificate of examination of regulations and rules of work in electroinstallations which shall contain record about the admission to accomplishment of these works, according to User Safety Rules for Operating Electrical Equipment, approved by the Government of the Republic of Kazakhstan.

Treat special works:

1) steeplejack works;

To all personnel which are in rooms with the operating power equipment of power plants and substations (except for control panels, relay and it similar), in the closed distribution installations (further - ZRU) and open distribution installations (further - I SHOUT), wells, tunnels and trenches, and also participating in servicing and capital repairs of VL, it is necessary to use protective helmets.

7. In electroinstallations it is higher than 1000 V to the workers from the person on duty or operational maintenance force solely servicing electroinstallations, and seniors on change need to have group IV, the rest - III.

In electroinstallations to 1000 V the workers from the person on duty or operational maintenance force solely servicing electroinstallations need to have group III.

8. In electroinstallations approach of the people, mechanisms and hoisting machines to not protected current carrying parts which are energized on distances which were less specified in the table 1 of appendix 4 to these rules is not allowed.

9. Survey of electroinstallations of power plants and substations is carried out by one worker with group of III of the person on duty or operational maintenance force who is on watch or the worker with group of V of administrative technicians.

10. The workers who are not servicing these electroinstallations are allowed in them accompanied by the person on duty or it is higher than 1000 V of the operational maintenance force having group IV in electroinstallations also group III - in electroinstallations of 1000 V, or the worker having the right of individual survey.

The attendant needs to watch safety of the people allowed in electroinstallations and to warn them about non-admission to approach current carrying parts on distances, less specified in the table 1 of appendix 4 to these rules.

11. Higher than 1000 V in case of survey are not allowed in electroinstallations to enter the rooms, cameras which are not equipped with the barriers or barriers interfering approach to current carrying parts on distances, less specified in the table 1 of appendix 4 to these rules. It is not allowed to open doors of barriers and to get for barriers and barriers.

In electroinstallations to 1000 V in case of survey it is allowed to open doors of boards, assemblies, control panels and other devices. Accomplishment of any works is not allowed during survey.

12. In case of short circuit on the earth in electroinstallations of 6-35 kil to approach the found place of short circuit on distance less than 4 meters in ZRU and less than 8 meters in the SHOUTING and on VL it is allowed only for operational switchings for the purpose of liquidation of short circuit and release of the people who got under tension. At the same time it is necessary to use electroprotective equipment.

13. It is necessary disconnect and turn on disconnectors, separators and switches higher than 1000 V with the manual drive in dielectric gloves.

14. It is necessary to remove and establish safety locks at the removed stress.

Energized, but without loading it is allowed to remove and establish safety locks on accessions in which scheme there are no switching devices allowing to remove stress.

Under loading it is allowed to replace safety locks in secondary chains, networks of lighting and safety locks of transformers of tension.

15. In case of removal and installation of safety locks energized it is necessary to use:

in electroinstallations it is higher than 1000 V - the isolating pincers (bar) using dielectric gloves and goggles; in electroinstallations to 1000 V - the isolating pincers or dielectric gloves and goggles.

16. In case of arrangement of safety locks of accession vertically one over another (vertical arrangement of phases) on boards and assemblies to 1000 V and lack of switching devices is allowed to establish and remove safety locks under loading. At the same time it is necessary to apply instead of eye protections of remedy of person.

17. Doors of rooms of electroinstallations, cameras, boards and assemblies are closed on the lock, except cameras in which works are carried out.

On the mast transformer substations, switching Items and other devices which do not have barriers, drives of disconnectors, and also stationary ladders on the platform of servicing are locked. Stationary ladders, besides, are blocked with disconnectors.

18. Keys from electroinstallations it is higher than 1000 V (rooms and cameras ZRU, KRU, I SHOUT), and also from switchboards and assemblies to 1000 V located out of electroinstallations it is higher than 1000 V, are on accounting at personnel on duty. Without local staff on duty keys are in electroinstallations on accounting at administrative technicians.

Keys are stored in the locked box. One set of keys remains reserve.

Keys are issued on receipt:

1) to the workers having the right of individual survey from all rooms;

2) in case of the admission allowing from operational maintenance force, to the head and the operator (observing) from rooms in which it is necessary to work.

19. Keys are subject to return daily upon termination of survey or work. During the work in electroinstallations without local staff on duty keys return no later than the next working day after survey or complete completion of work.

Need of issue of keys for long term to the personnel of consumers having the right of operational switchings in RU of the companies of power supply networks and also the person on duty, operational repair and to the administrative technicians having the right of individual survey is determined by the technical lead of the company.

Issue and return of keys are considered in the magazine of any form or in the operational magazine.

20. In case of accidents for release of the victim of action of electric current stress is removed immediately without preliminary approval.

2. The actions ensuring safety of performance of works

21. Works in electroinstallations under the terms of ensuring electrical safety to their primary chains are divided into four categories:

1) with removal of tension (with induced and without the induced tension);

2) without removal of tension using electroprotective equipment;

3) without removal of tension on the potential of current carrying part;

4) far from the current carrying parts which are energized.

22. Electrical safety working in category "with removal of tension" is provided with electroinstallation shutdown, installation of protective grounding on current carrying parts on workplace, workplace barrier.

At the induced tension on current carrying parts electrical safety is provided with the measures provided in Items 311-325 of these rules.

23. Electrical safety working in category "without removal of tension using electroprotective equipment" is provided with isolation working from the current carrying parts which are energized by means of the main protective equipment.

24. Electrical safety working in category "without removal of tension on the potential of current carrying part" is provided to that working, applying special set of clothes and special devices, is isolated from the grounded current carrying parts and designs on the distances specified in the table 1 of appendix 4 to these rules.
