The procedure for organizing work according to work order. Who is the permitter in the clearance order? Responsibilities and rights Who are the issuing outfit, admitting observer

Classification of premises and electrical installations according to the degree of electronics. danger.

The state of the surrounding air, as well as the surrounding environment, can increase or decrease the risk of electric shock. Thus, dampness, conductive dust, caustic vapors and gases have a destructive effect on the insulation of the EC-IC, sharply reducing its resistance and creating a threat of voltage transfer to the housings, frames, casings and similar non-current-carrying metal parts of the EC-IC that can be touched by a person. Depending on certain conditions that increase the danger of exposure to electric current on a person, different rooms have different degrees of danger of electric shock - some are greater, others are less. Rooms without increased danger include dry, dust-free rooms with normal air temperature, with insulated floors, in which there are no grounded objects or very few of them. In other words, this is a room in which there are no signs characteristic of high-risk and especially dangerous rooms. Premises with increased danger include premises: damp ones in which the relative air humidity exceeds 75% for a long time; hot in which, under the influence of various thermal radiation, the air temperature exceeds constantly or periodically for more than 1 day. 35C; dusty with conductive dust in which, due to production conditions, conductive process dust (coal or metal, etc.) is released; With conductive floors - metal, earthen, reinforced concrete, brick. Particularly dangerous premises include: particularly damp ones, i.e. rooms in which the relative air humidity is close to 100%; with a chemically active or organic environment that constantly or for a long time contains aggressive vapors, gases, liquids, deposits or mold are formed that have a destructive effect on the insulation and live parts of the electrical equipment; Having two or more characteristics characteristic of high-risk premises.

Organizational measures to ensure the safety of work during complete or partial stress relief.

3) Preventing the source of explosion initiation.

Strict regulation of hot work;

Preventing equipment from heating to a temperature capable of exploding the environment;

Use of explosion-proof equipment;

Application in enclosures of special electrical equipment. materials and alloys that do not create frictional sparking upon impact;

Application of protection against current leakage, short circuit;

Application of means of protection against stat. and magician fields;

Limiting the power of discharges, sparks, arcs.

Thus, the basic principle of explosion safety is Construction of such a technology. a process that eliminates the formation of an explosive atmosphere both in the working space of the mine and inside the process. equipment, and in the event of an explosion or fire, reducing its impact.

The procedure for organizing work according to work order.

Work permit (work order) - a task for the performance of work, drawn up on a special form of the established form and defining the content, place of work, time of its beginning and end, conditions for safe performance, composition of the team and persons responsible for the safe performance of work.

The order is issued in two copies, and when transmitted by telephone or radio - in triplicate. In the latter case, the issuing order issues one copy, and the employee receiving the text in the form of a telephone or radio message, fax or e-mail, fills out two copies of the order and, after checking back, indicates his surname and initials at the place of the signature of the issuer of the order, confirming the correctness of the entry with his signature .

In cases where the work performer is appointed at the same time as admitting, the work order, regardless of the method of its transmission, is filled out in two copies, one of which remains with the issuing work order.

Depending on local conditions (location of the control center), one copy of the order may remain with the employee who authorizes the preparation of the workplace (dispatcher).

The number of orders issued to one responsible work manager is determined by the issuing order.

The permitter and the work supervisor (supervisor) may be issued several orders and orders at once for alternate admission and work on them.

A work order may be issued for a period of no more than 15 calendar days from the date of commencement of work. The work order can be extended once for a period of no more than 15 calendar days from the date of extension. During breaks in work, the work order remains valid.

The work order can be extended by the employee who issued the work order, or by another employee who has the right to issue a work order for work in an electrical installation.

Permission to extend the work order can be transmitted by telephone, radio or by hand to the permitting, responsible manager or work manager, who in this case, with his signature, indicates in the work order the surname and initials of the employee who extended the work order.

Work orders for which work is completely completed must be stored for 30 days, after which they can be destroyed. If accidents, incidents or mishaps occurred while performing work according to the orders, then these orders should be stored in the organization’s archives along with the investigation materials.

Accounting for work on orders is kept in the Register of Work Orders and Orders.

The work order may be issued to one or more workplaces in an electrical circuit (equipment and busbars) of the same purpose, name and voltage, connected to the busbars of a switchgear, generator, switchboard, assembly and located within a power plant, substation (hereinafter referred to as the connection), taking into account the requirements, specified in paragraphs 6.8, 6.9, 6.11, 6.12, 6.14 of the Rules.

Electrical circuits of different voltages of one power transformer (regardless of the number of windings), one two-speed electric motor are considered one connection. In polygon circuits and one-and-a-half circuits, the connection of a line or transformer includes all switching devices and buses through which this line or transformer is connected to the switchgear (6.7).

In electrical installations with voltages above 1000 V, where the voltage is removed from all live parts, including the inputs of overhead lines and cable lines, and the entrance to adjacent electrical installations is locked (assemblies and panels up to 1000 V can remain energized), it is allowed to issue one work order for simultaneous work on busbars and all connections.

In electrical installations with voltages up to 1000 V, with the voltage completely removed from all current-carrying parts, it is allowed to issue one work order to perform work on switchgear busbars, distribution boards, assemblies, as well as on all connections of these installations simultaneously (6.8).

When units (boilers, turbines, generators) and individual technological installations (ash removal systems, network heaters, crushing systems) are taken out for repair, it is allowed to issue one work order for work on all (or part) of the electric motors of these units (installations) and one work order for work on Switchgear on all (or part) connections feeding the electric motors of these units (installations).

It is allowed to issue one work order only for work on electric motors of the same voltage and connections of the same switchgear (6.9).

When working one at a time on electric motors and their connections in a switchgear facility equipped with switchgear cabinets, registration of transfer from one workplace to another is not required; dispersal of team members across different workplaces is allowed. In switchgear of a different design, approval and work on electric motor connections must be carried out with registration of transfer from one workplace to another (6.10).

In a switchgear with a voltage of 3-110 kV with a single busbar system and any number of sections, when one of the sections with connections is taken out for repair, it is fully permitted to issue one work order for work on the busbars and on all (or part) of the connections of this section. Dispersal of team members across different work stations within this section is allowed (6.11).

Question. In what cases is it permissible to issue one work order for the simultaneous or alternate performance of work at different workplaces?

Answer. One work order for simultaneous or alternate performance of work at different workplaces of the same electrical installation may be issued in the following cases:

when laying and relaying power and control cables, testing electrical equipment, checking protection devices, measurements, blocking, electrical automation, telemechanics, communications;

when repairing switching devices of one connection, including when their drives are located in another room;

when repairing a separate cable in a tunnel, collector, well, trench, pit;

when repairing cables (no more than two), carried out in two pits or switchgear and a nearby pit, when the location of workplaces allows the work manager to supervise the team.

At the same time, the dispersal of team members across different workplaces is allowed. Registration of transfer from one workplace to another in the work order is not required (6.12).

When carrying out work in accordance with clauses 6.8, 6.9, 6.11, 6.12 of the Rules, all workplaces must be prepared before the team is admitted to the first workplace.

Preparations for switching on any of the connections, including testing of electric motors, are not allowed until work on the work is completed.

In the case of dispersal of team members to different work places, one or more team members with group III are allowed to remain separately from the work producer.

Members of the team who are to be separated from the work supervisor must be brought to the workplace and instructed by the latter on the safety measures that must be observed when performing work (6.13).

It is allowed to issue one work order to alternately carry out the same type of work at several electrical installations intended for the conversion and distribution of electrical energy (hereinafter referred to as substations) or several connections of one substation.

Such work includes: wiping insulators; tightening contact connections, sampling and adding oil; switching branches of transformer windings; testing of relay protection devices, electrical automation, measuring instruments; high voltage test from an external source; checking insulators with a measuring rod; finding the location of the cable damage. The validity period of such an order is 1 day.

Admission to each substation and each connection is issued in the corresponding column of the work order.

Each of the substations is allowed to be put into operation only after complete completion of work on it (6.14).

Question. How is work organized at overhead line sections in the RU?

Answer. Work on overhead power lines located on the territory of the switchgear must be carried out according to orders issued by the personnel servicing the overhead lines. When working on an end support, local operating personnel must instruct the crew to guide them to the end support. In electrical installations that do not have local operating personnel, the line crew supervisor is allowed to receive the key to the switchgear and independently go to the support.

When working on outdoor switchgear portals, indoor switchgear buildings, roofs of complete outdoor switchgears (KRUN), the admission of the line crew with the necessary registration in the work order must be carried out by an admitter from among the operational personnel servicing the switchgear.

The work manager with the line crew has the right to leave the plant independently, and individual members of the crew - in the manner prescribed by clause 11.3 of the Rules (6.15).

Question. How is work organized at cable lines sections in the RU?

Answer. Work on the end couplings and terminations of cable lines located in the switchgear must be carried out according to orders issued by the personnel servicing the switchgear. If the switchgear and cable lines belong to different organizations, then these works are carried out in accordance with the requirements set out in Chapter XLVI of the Rules.

Permission to work on cable lines in these cases is carried out by personnel servicing the reactor plant.

Work on cable lines passing through the territory and in the cable structures of the switchgear must be carried out according to work orders issued by the personnel servicing the cable lines. Access to work is carried out by personnel servicing the cable line after receiving permission from the operational personnel servicing the reactor plant (6.16).

Question. How is work organized on communication devices located in the switchgear?

Answer. Work on communication devices located in the switchgear is carried out according to orders issued by SDTU service personnel. It is allowed to issue such orders by personnel servicing the reactor plant. Exceptions include work on coupling capacitors and high-frequency suppressors, which should be carried out only according to orders issued by workers servicing the reactor plant.

Preparation of workplaces and permission to work in SDTU devices located in the reactor plant are carried out by personnel servicing the reactor plant (6.17).

Question. How is work organized on overhead lines?

Answer. A separate order is issued for each overhead line, and for multi-circuit overhead lines, for each circuit. It is allowed to issue one work order for several overhead lines (circuits) in the following cases:

during work when the voltage is removed from all circuits, or when working under voltage, when the voltage is not removed from any circuit of a multi-circuit overhead line;

when working on overhead lines at their intersections;

when working on overhead lines with voltages up to 1000 V, performed one by one, if the transformer points or complete transformer points from which they are powered are disconnected;

during similar work on non-current-carrying parts of several overhead lines that do not require their shutdown (6.18).

The work order must indicate whether the overhead line being repaired is under induced voltage, as well as overhead lines crossing the line being repaired that need to be disconnected and grounded (with grounding installed in accordance with Chapter XXII of the Rules). The same instruction must be included in the work order regarding overhead lines passing near the one being repaired, if their disconnection is required by operating conditions. In this case, grounding of overhead lines crossing the one being repaired or passing nearby must be performed before permission to work. It is not allowed to remove the grounding connections from them until the work is completed.

If the overhead lines belong to other organizations, their disconnection must be confirmed by the operational staff of the owner of the overhead line (6.19).

For phased repairs of overhead lines, a work order is issued for work only on the area of one transposition step.

On disconnected overhead lines, it is allowed to disperse the crew over an area of no more than 2 km, with the exception of installation and dismantling of wires (cables) within

longer anchor span. In this case, the length of the work area of one team has the right to determine the issuing work order.

When work is carried out on live parts under voltage, the team must be on one support (in one intermediate span) or on two adjacent supports (6.20).

When working on the same work order in different areas, overhead line supports, the transfer of the team from one workplace to another is not documented in the work order (6.21).

Organizational activities include:

1) registration of work with a work permit, order or list of work performed in the order of current operation;

2) permission to work;

3) supervision during work;

4) registration of breaks in work, transfers to another workplace, end of work.

Outfit - this is a task for the production of work, drawn up on a special form of the established form and defining: the content, place of work, start and end times of work, conditions for safe work, composition of the team and persons responsible for the safety of work.

In addition, work can be carried out in electrical installations by:

1) with stress relief;

2) without relieving voltage on live parts and close to them;

3) on an overhead line additionally - without removing the voltage away from live parts that are energized:

This person must have a group not lower than that required for the persons whose duties he combines.

When working on-site in electrical installations with voltages above 1000V without permanent maintenance personnel, persons from the operational and repair personnel are allowed to combine the duties of the permitting and responsible manager.

In electrical installations up to 1000V - the manufacturer of the work and the permitter. Permit and team member - when working under orders.

On overhead lines up to and above 1000V, it is allowed to combine the responsibilities of the manufacturer and the permitter in all cases.

Procedure for issuing the work order:

In duplicate. Clearly, clearly, without corrections. It is possible by phone (then in 3 copies) with a reverse check (dictated by the issuer from an already completed work order).

One copy is issued to the manufacturer immediately before the start of work.

When expanding the workplace or changing the number of workplaces, a new work order must be issued. The team must consist of at least two people.

Brigade composition determines the issuing outfit. The number and qualifications of team members - taking into account the conditions.

In a team led by the manufacturer, for one team member with group III, 1 person with group I can be included, but no more than two.

Operational personnel may be included in the repair team with the permission of higher operational personnel without being included in the work order, with an entry in the operational log.

Changes in the composition of the team working under orders are prohibited.

Authorization of the team to work.

Before admission, the work foreman and the responsible manager, together with the person admitting, check the implementation of technical measures.

After checking and briefing the team, the responsible manager signs the work order.

The admitter checks:

1) compliance of the composition of the brigade and the qualifications of the persons included in it, the entries in the outfit (if the person admitting does not know the names, the check is carried out using personal identification cards);

2) reads along the names of the responsible persons, the content of the assigned work, explains to the brigade where the voltage has been removed, where the ground connections are applied, which parts of the repaired and adjacent connections remain energized, what special conditions for the work must be observed, indicates to the brigade the boundaries of the workplace, makes sure that that everything stated is clear to the brigade;

3) proves to the team that there is no voltage: in electrical installations >35 kV - by showing the applied portable grounding, in electrical installations up to 35 kV where the grounding is not visible from the place of work - by touching live parts with the hand after preliminary checking the absence of voltage with a pointer or rod;

4) hands over the workplace to the work producer, which, indicating the date and time in both orders, is documented with the signatures of the permitter and the work producer.

Admission must be made directly at the workplace.

One copy is for the manufacturer, the second is for the operational personnel in the folder of existing orders.

The time of admission and completion of work, indicating the work order number and content of the work, is recorded in the operational journal.

The right of secondary admission in subsequent days is granted to the responsible manager, and in his absence - to the person performing work with group no lower than IV - in electrical installations up to 1000V, and in electrical installations above 1000V - not lower than group V.

Supervision during work.

The observer is constantly at the workplace from the moment of admission and at the most critical areas of work. It is prohibited to combine supervision with other work.

If it is necessary to leave, the manufacturer (supervisor) (if he cannot be replaced by the responsible manager, the manufacturer who issued the order, or a person from the operational staff) is obliged to take the team out of the control room, lock the door behind him, and arrange a break in the work order.

The responsible manager and operational personnel must periodically check compliance with safety regulations by workers; if violations are detected, the manufacturer’s work order is taken away and the team is removed from the workplace. After the violations have been eliminated, the team is again admitted by operational personnel in the presence of the responsible manager with the admission issued in the work order.

Changes in the composition of the brigade.

Allowed only when working alongside. Changes are drawn up in the order by the issuer, or in his absence - by the person who has the right to issue in this electrical installation.

The manufacturer is obliged to instruct the workers included in the team.

When replacing a team by more than 50%, or a manager, or a manufacturer, a new work order must be issued.

Registration of work breaks.

There are two types:

1) during the working day (lunch, according to work conditions). In this case, the brigade must be withdrawn from the control room. Posters, fences, and grounding remain in place. The work order remains with the work manufacturer. Without a work producer, no one has the right to enter the RU. No admission is granted;

2) at the end of the working day, posters. In this case, the grounding and fences remain in place. The end of the working day is signed by the work producer.

In electrical installations with permanent operating personnel, the work order is handed over every day to a person from the operating staff and is signed by them on the work order. In electrical installations without permanent operating personnel - left in the folder of current work orders (only the signature of the work contractor is allowed).

The next day, the work site is inspected and the implementation of safety measures is checked by the permitting or responsible manager or the work performer. The signatures of the permitter and the work manufacturer are affixed.

Transfer of the team to another workplace.

Can only be carried out when working along side lines.

Work at several workplaces of the same connection in one job can be carried out subject to the following conditions:

1) all workplaces of this connection are prepared by operational personnel and accepted by the work manufacturer and the responsible manager before the start of work;

2) the work foreman with the team is allowed to one of the connection workplaces;

3) in electrical installations with permanent operating personnel, the transfer of the team to another workplace is carried out by the permitting person;

4) in electrical installations without permanent operating personnel, the transfer of the team to another workplace in the absence of a permitting one is carried out by the responsible manager;

5) the transfer of the team to a new workplace is documented in table 3 of the work order “Daily admission to work and its completion” and if the transfer is carried out by a responsible manager, he signs in the table instead of the one who allows it.

Completion of work.

After complete completion of the work, the workplace is put in order, accepted by the responsible manager, who, after the team has left the manufacturer, signs the work order and hands it over to the operational personnel, or leaves it in the folder of existing work orders.

The work order can be closed after the operating personnel have inspected the equipment and the place of work, checked the absence of people, foreign objects, tools, and with proper cleanliness.

Closing the outfit.

The closure of the order is documented by an entry in the operational journal.

When work is carried out on one connection by several teams, the work order can be closed upon completion of the work by one team, indicating in the work order “groundings are left for work according to work order No. ...”.

Closing of the work order is carried out after the following are sequentially completed:

1) removal of temporary fences and removal of posters “Work here”, “Climb here”;

2) removal of groundings with verification in accordance with the accepted accounting procedure;

3) installation of permanent barriers and removal of other posters posted before the start of work.

Checking the insulation of repaired equipment immediately before switching on is carried out, if necessary, before removing temporary fences and warning posters, immediately after removing portable grounding connections.

The equipment can only be turned on after the work order is closed.

If work was carried out on several orders at a disconnected connection, then it can be included in the work only after all orders have been closed.

Validity the work order is set for up to 5 days, except for the same type of operational work at several substations, at one or more connections of each substation (wiping insulation, tightening clamps, checking relay protection and automation devices, measuring instruments, testing with high voltage, checking insulators with a measuring rod). The validity period of this order is one day.

During breaks in work, the work order remains valid if the schemes were not restored and the conditions of work remained unchanged.

Control the correctness of execution of work orders is carried out by the person who issued them and by persons from the management electrical personnel periodically through random checks.

Work orders for which work is completely completed must be stored for 30 days, after which they must be destroyed.

If accidents or electrical injuries occurred while performing work according to orders, then these orders should be stored in the archives of the enterprise.
