These instructions must be known and followed by electricians servicing electrical installations, as well as administrative and technical personnel in charge of maintenance and repair. Failure to comply with instructions is a violation of labor and production discipline. Persons who violate these instructions are liable (disciplinary, administrative or criminal) in accordance with applicable law, depending on the nature and consequences of the violation. For these persons, the management of the enterprise may be reduced by the electrical safety group. Electricians for the repair of overhead, cable power lines can be persons who are at least 18 years old, physically, mentally healthy, as evidenced by a medical examination, who have undergone the necessary theoretical and practical training, introductory and primary instruction, on-the-job training under the guidance of a qualified worker, as well as training ways to free the victim from the action of electric current and provide first aid to the victim, pass exams at the qualification commission of the power supply distance. Persons who have successfully passed the exams are issued certificates, which must be on hand during the performance of official duties, as well as a warning coupon and present them upon request to persons exercising control over the implementation of the requirements and norms for labor protection and safety. An electrician for the repair of overhead, cable power lines TP, PTS is required to know and perform:
An electrician for the repair of overhead, cable power lines is obliged to comply with the requirements of labor protection regulations, the requirements of this instruction, the rules of conduct with machines, mechanisms, equipment and other means of production at his workplace. Electricians are delivered from the base of the EHS or the repair center to the place of work by motor transport, railway transport, on foot. Harmful factors in the workplace are: electric current, height, train traffic, induced voltage, thunderstorms, ambient temperature, hoisting machines and mechanisms. Electricians for the repair of overhead power lines are provided free of charge with overalls, special. footwear, personal protective equipment. When a thunderstorm approaches, all work in the distribution networks must be stopped, the team must be withdrawn from the place of work. All electricians, when performing work in existing electrical installations of indoor switchgear, outdoor switchgear, wells, tunnels and trenches, as well as those involved in the maintenance and overhaul of overhead lines, must wear protective helmets. Protective helmets are designed to protect the head from mechanical damage, precipitation, electric shock. All electricians while on the railway. on the tracks must wear high-visibility vests or work suits with a high-visibility insert. Before leaving for work, as well as immediately before performing an external inspection, you should make sure that the protective equipment or installation device used is in good condition. If any deficiencies are identified, they should be immediately reported to the head of the unit or the work manager. The protective device or mounting device must be replaced with a correct one. It is forbidden to use protective equipment and mounting devices for work:
It is forbidden to work in clothes with short or rolled up sleeves, as well as to use hacksaws, files, metal meters, etc. near live parts. Electricians who have committed a violation of this instruction bear disciplinary responsibility: they may be sanctioned - a reprimand, or dismissal from work. For such employees, the electrical safety group may be reduced. In cases where violation of the requirements of safety rules and instructions on labor protection has led to material losses, the perpetrators are liable to compensate for the material loss, and the perpetrators may also be held criminally liable. 2. Safety requirements before starting work Before starting work, the electrician must receive an order or order, or be a member of the team for which the order, order is issued, and be instructed in the safe performance of work. Without fulfilling the specified conditions, it is prohibited to start work in electrical installations. Get your uniform in order. Clothing must be buttoned up and not restrict the movement of the worker, the sleeves are lowered and fastened near the wrist. Check the sufficiency and serviceability of protective equipment and tools. Replace defective protective equipment with serviceable ones. Receive orders for the production of work according to the order or order from the energy dispatcher or work foreman. Unauthorized expansion of the workplace specified by the work permit or by order of the energy dispatcher is prohibited. Major repairs of electrical equipment above 1000 V and overhead lines, regardless of voltage, must be carried out according to technological maps. Work on the dismantling of supports and wires of overhead lines, as well as when replacing support elements, must be carried out according to technological maps under the supervision and control of the EChS engineer. The personnel who service the overhead line should be familiar with the list of lines that, after disconnection, may be under induced voltage. The list of such overhead lines is compiled by the person responsible for the electrical facilities of the workshop and acquaints all personnel against signature in the briefing log. On the territory of EChS, industrial and amenity premises, workplaces, it is prohibited:
In the event of a fire, it is necessary to urgently report to the energy dispatcher, inform the fire train. Prior to the arrival of the fire brigade, it is necessary to start extinguishing the fire with primary fire extinguishing equipment, having previously turned off the electrical installation. Upon arrival of the fire brigade, the fire is extinguished under the guidance of firefighters. It is forbidden to perform tasks that do not comply with the requirements of safety regulations. If there is any doubt about the possibility of safely completing the task, the electrician should contact the issuer of the task for clarification. Having discovered a violation of safety requirements or a threat to people's lives, the electrician must take measures to eliminate them. If he cannot take measures to eliminate violations on his own, he must contact the management of the EES, ECH. Operational maintenance of electrical installations can be carried out by operational or operational maintenance personnel. Operational maintenance of electrical installations is allowed for persons who know operational schemes, job descriptions and operating instructions, equipment features, who have been trained and tested in accordance with the Law of Ukraine "On Labor Protection". Persons from the operational personnel serving electrical installations alone, to whom this electrical installation is assigned, must have an electrical safety group of at least IV in electrical installations above 1000 V and III in electrical installations up to 1000 V. Operational personnel are obliged to conduct rounds and inspections of equipment and production facilities in the area assigned to them in accordance with the service boundaries. Operational service consists of:
Inspection of electrical installations can be carried out solely by persons from the operational and repair personnel servicing this electrical installation with an electrical safety group of at least III in electrical installations up to 1000 V, not lower than IV in electrical installations above 1000 V. It is forbidden to combine inspection with the performance of work. When inspecting an overhead line or an air switching point, it is prohibited to climb a support or structures. In difficult terrain and in adverse weather conditions, the inspection of the overhead line should be carried out by two persons with an electrical safety group of at least II. When viewed at night, walking under the wires is not allowed. Works in electrical installations in relation to safety measures are divided into those performed:
With simultaneous work in electrical installations with voltages up to and above 1000 V, the categories of work are determined in relation to electrical installations with voltages above 1000 V. Work performed with stress relief includes work that is carried out in an electrical installation in which voltage is removed from current-carrying parts. Work performed without removing voltage on current-carrying parts and near them includes work carried out directly on these parts. Work without removing voltage on current-carrying parts and near them must be performed by at least two persons, of which the worker must have an electrical safety group of at least IV, the rest - at least III. Work without de-energizing away from live parts under voltage is considered to be such work in which the accidental approach of working people and the repair equipment and tools they use to live parts at a distance of at least 0,6 m is excluded and does not require the adoption of technical or organizational measures ( e.g. continuous surveillance) to prevent such approach. Organizational measures that ensure the safety of work in electrical installations are:
When preparing the workplace for work with stress relief, the following technical measures must be taken in the specified order to ensure the safety of work:
Depending on local conditions, current-carrying parts should be protected before and after grounding. 3. Safety requirements during work General safety requirements. Safety requirements for being on the railway tracks. When passing along the tracks on the stage, alone or in a group, go away from the track or along the side of the road, at the station go along the side of the track, in the middle of the widest inter-track or along the passage route established for this station; at the same time, it is necessary to monitor moving trains, shunting trains and locomotives. When passing through the tracks, you should first look around and make sure that the rolling stock (locomotives, wagons, railcars, etc.) is not approaching the crossing point, you should cross the tracks at a right angle; at the same time, you must not stand on the head of the rail between the wit and the frame rail of the turnout. When following a group, go one by one or two people at a time; avoiding backlog and crowd movement. When crossing a track occupied by a standing rolling stock, it is forbidden to use the transitional platforms of wagons or bypass the train, it is forbidden to crawl under wagons or automatic couplers and drag tools, mounting devices and materials under them. Before leaving the wagon platform on the inter-track, you must also make sure that there are no locomotives and wagons moving along the adjacent track. When leaving the platform, you should hold on to the handrails, facing the car. It is forbidden to cross the track in front of approaching locomotives, wagons, railcars. When bypassing a group of wagons or a locomotive, and pass between uncoupled wagons if the distance between them is at least 10 m. At the same time, you should make sure that a train, a shunting train, a single locomotive or a cutaway is not moving along the adjacent track. It is not allowed to sit on the rails, the ends of the sleepers, the ballast prism, the choke - transformers, as well as any other devices located both within and near the gauge of the rolling stock. If it is not possible to pass away from the track or along the side of the road, then it is allowed to pass along the track subject to the following requirements: on double-track sections, it is necessary to go towards the movement of trains; fire), ahead of the group should be protected by a specially assigned worker in the above order. No closer than 400 m to the approaching train, you should move to the side of the road at a distance of at least 2 m from the outermost rail at a speed of up to 120 km/h, 4m - from 121 to 160 km/h, 5m - from 161 to 200 km/h . Before crossing a railway bridge or tunnel, make sure that no train is approaching it. It is allowed to pass over bridges and tunnels less than 50 m long only when the approaching train is not visible; it is necessary to take cover on special platforms or in shelter niches. When working in electrical installations with voltage up to 1000 V without removing the voltage on current-carrying parts and near them, it is necessary:
When performing work without removing voltage on live parts using insulating protective equipment, it is necessary:
If a violation of the varnish coating or other malfunctions of the insulating protective equipment is detected, their use must be immediately discontinued. During rain and fog, work requiring the use of protective equipment is prohibited. Work in electrical installations is carried out according to order, order, in the order of current operation. An order is an assignment for the safe production of work, drawn up on a special form of the established form and determining the content and place of work, the time it starts and ends, the conditions for safe conduct, the composition of the team and persons responsible for the safety of the work. Along with this, all maintenance work on electrical installations is carried out, performed:
An order is a task for the production of work, which determines its content, place, time, security measures and persons who are entrusted with its implementation. The order is recorded in the operational journal. Current operation is the performance by operational, operational and repair personnel independently on the site assigned to them during one shift of work according to the list drawn up in accordance with the requirements for the operation of consumer electrical installations. Responsible for work safety are:
Shutdown production. At the place of work with voltage removal in electrical installations with voltages above 1000 V, the following must be turned off:
In electrical installations with voltages above 1000 V, on each side from where the switching device can supply voltage to the place of work, there must be a visible break formed by disconnecting or removing wire busbars, disconnecting wire disconnectors, disconnecting disconnectors, removing fuses, as well as disconnecting separators and load switches, with the exception of those in which automatic activation is carried out by springs installed on one apparatus. Voltage transformers and power transformers associated with the section of the electrical installation allocated for work must also be disconnected from the side of voltage up to 1000 V in order to prevent reverse transformation. After disconnection, you must visually verify that the device is disconnected and there is no shunt jumper In electrical installations with a voltage of up to 1000 V from the current-carrying parts on which work will be carried out, the voltage from all sides must be removed by turning off the manually operated switching devices, and if there are fuses in the circuit, by removing the latter. If there are no fuses in the circuit, the prevention of erroneous switching on of switching devices must be ensured by the following measures:
Checking the absence of voltage. Before starting all types of work in electrical installations with de-energization, it is necessary to check the absence of voltage in the work area. In electrical installations, it is necessary to check the absence of voltage with a factory-made voltage indicator, the serviceability of which must be established before use by means of special devices designed for this purpose or by approaching live parts located nearby and obviously under voltage. In electrical installations with voltages above 1000 V, it is necessary to use a voltage indicator with dielectric gloves. On wooden and reinforced concrete supports with a voltage of 6-20 kV, as well as when working from a telescopic tower, when checking the absence of voltage with a pointer based on the principle of capacitive current flow, its necessary sensitivity must be ensured. To do this, the working part of the indicator should be grounded with a wire with a cross section of at least 4 mm2. On overhead lines, when hanging wires at different levels, check the absence of voltage with a pointer or rod and grounding should be applied from the bottom up, starting from the bottom wire. With a horizontal suspension, the test must begin with the nearest wire. In electrical installations with voltage up to 1000 V with a grounded neutral, when using a two-pole indicator, it is necessary to check the absence of voltage both between phases and between each phase with a grounded equipment case or ground wire. It is allowed to use a previously checked voltmeter. The use of pilot lamps is prohibited. Grounding of live parts. Grounding of current-carrying parts is carried out in order to protect workers from electric shock in case of erroneous voltage supply to the place of work, to exclude the influence of induced voltage. It is necessary to apply grounding to current-carrying parts immediately after checking the absence of voltage. Portable grounding must first be connected to the ground, and then, after checking the absence of voltage, applied to live parts. Portable grounding should be removed in the reverse order of overlay - first remove them from live parts, and then disconnect them from the ground. Operations for applying and removing portable grounding are performed in dielectric gloves using an insulating rod in electrical installations with voltages above 1000 V. In electrical installations with voltages above 1000 V, grounding is applied to the current-carrying parts of all phases, poles of the section of this electrical installation disconnected for work from all sides, from where voltage can be applied, with the exception of busbars disconnected for work, on which it is enough to apply one grounding. Portable grounds applied to live parts must be separated from live parts under voltage by a visible break. Grounding should be applied in places cleared of paint. In indoor switchgear and open switchgear, the connection of portable grounding to grounding wiring or to grounded structures must be cleaned of paint and adapted for grounding. In electrical installations above 1000 V:
In electrical installations up to 1000 V, installation and removal of grounding operations is allowed to be performed by one employee with group III from the operational or operational production personnel. Overhead lines above 1000 V must be grounded in all switchgears and at sectional switching devices where the line is disconnected. It is allowed to ground 6-10 kV overhead lines only in one switchgear or at the nearest switchgear to the switchgear or sectional device to the support. The rest of the switchgear of this voltage and at the sectioning devices, where the overhead line is turned off, it is allowed not to ground it, provided that groundings are installed on the overhead line between the workplace and this switchgear or sectioning devices from all sides from where voltage can be applied. On single-circuit overhead lines, grounding at the workplace must be installed on adjacent supports from the place of work. It is allowed to stop grounding on both sides of the overhead line section on which the team works, provided that the distance between groundings does not exceed 2 km. If the line is under induced voltage, then the distance between portable grounding should not exceed 200 m. Portable grounding should be applied on metal supports - to their elements on reinforced concrete and wooden supports with grounding slopes - to these slopes after checking the integrity. In electrical networks up to 1000 V with a grounded neutral, if there is a re-grounding of the neutral wire, it is allowed to use portable grounds to this wire. Portable grounding at the workplace can be connected to a grounding conductor immersed in the ground at least 0,5 m. Portable grounding must meet the following requirements:
On each portable grounding, its number and the section of grounding wires are indicated. With the destruction of contact connections, a decrease in the mechanical strength of the conductors, their melting, breakage of more than 5% of the cores, if it was exposed to short-circuit currents, portable grounding should be withdrawn from consumption. Support work. Climbing and working on a support is permitted only in cases where there is confidence in the sufficient stability and strength of the support. The need and ways to strengthen the support, the strength of which is in doubt (insufficient first penetration, swelling of the soil, decay of wood, cracks in concrete), is determined on site by the work manager and members of the team. Work on strengthening the support with the help of stretch marks should be carried out without climbing onto the support, i.e. from a telescopic tower or other mechanism for lifting people, with a support installed nearby, or use special fastening devices for this, for which you do not need to climb the support. Climbing the support is allowed only after it has been strengthened. It is forbidden to break the integrity of the wires and remove the bindings on the intermediate supports without first strengthening the supports. When climbing on wooden and reinforced concrete supports, the safety belt slings should be wound behind the rack. It is forbidden to climb and work on corner supports with pin insulators from the side of the inner corner. cable lines. Before opening the sleeves or cutting the cable, it is necessary to make sure that these operations will be carried out on the cable on which it is necessary, that this cable is disconnected and the technical measures necessary to allow work on it are completed. On CL before cutting the cable or opening the coupling, it is necessary to check the absence of voltage using a special device consisting of an insulating rod and a steel needle or cutting tip. The devices should ensure puncture and cutting of the armor and sheath to the cores with their closure to each other and to the ground, the cable of the puncture site is preliminarily covered with a screen. The cable puncture is performed by a responsible work manager or a work supervisor who permits or under their supervision. The cable should be pierced with dielectric gloves and safety goggles. When piercing, you need to stand on an insulating base on top of the trench as far as possible from the pierced cable. To ground the piercing device, a special ground electrode is used, immersed in the soil to a depth of at least 0,5 m or cable armor. When working on a cable 4-core line with voltage up to 1000 V, the neutral core is disconnected from both ends. The cable mass for pouring the couplings is heated in a special metal container with a lid and spout. Do not heat unopened cans of cable mass. When pouring cable mass, canvas gloves and safety goggles should be worn. Warm up and carry a ladle or pot with solder, as well as vessels with cable mass, in canvas gloves and safety glasses. Sleeves of clothing are tied at the wrist over mittens or elbow-length mittens are used. It is forbidden to transfer a kettle or a ladle with solder or a vessel with a mass from hand to hand; when transferring, it is necessary to place them on the ground or on a solid foundation. The molten mass should be stirred with a metal stirrer, and deposits should be removed from the surface of the molten solder with a metal spoon. The stirrer and spoon are heated before use. Hot mass is not allowed. Working with a blowtorch. When working with a blowtorch, you must be guided by the following instructions:
Performing work on specially equipped rigid crossbars with lighting. Work on replacing burned-out lamps, repairing and replacing luminaires installed on rigid crossbars specially equipped with fencing is allowed to be carried out along with removing voltage from the supply line without removing voltage from the contact network. Removing voltage from the power line of the lighting device is carried out by turning off the circuit breakers at the ETP or PTS, contactors, and removing the fuses. Directly at the place of work, the YARV switch, the fuses are removed. After checking the absence of voltage in the supply line, a portable ground is installed at the meta works for all phases and a zero core in the YARV box. After briefing the brigade and admission to work, the brigade proceeds to perform work in accordance with the issued order. The lifting of fixtures and other parts on a rigid crossbar is carried out using an endless rope at the location of a stationary ladder for lifting people. The member of the brigade standing below must hold the rope to prevent swinging and approaching it to the contact network. The lifting is carried out under the supervision of the production of works. It is forbidden to use tools, devices that protrude beyond the size of the railing. Repair work fixtures and tools are tied to prevent them from falling. It is forbidden to use safety belts with slings with a metal chain. Take a stable position before starting work on the rigid crossbar. It is forbidden to carry out work on rigid crossbars to repair lighting during thunderstorms, rain, fog, ice and wet snowfall, without lighting the work site at night. Works on KTP, KTPOS, KTPP connected to DPR wires. Works at the PTS that require entering the fence and climbing structures must be carried out with voltage relief and grounding. The foreman must have a qualification group of at least V, and the performer must have at least III. When ensuring work at the KTP and KTPO, the following procedure must be observed:
Grounding should be applied to disconnected current-carrying parts from all sides, from where voltage can be applied. Places for applying grounding should be chosen so that they are visible, or so that workers can verify the presence of grounding at any time. Additional grounding should also be applied to current-carrying parts directly at the place of work. The points of connection of portable grounding to the grounding wiring on the circuit must be cleaned of paint and adapted to securely fasten the portable grounding of the portable grounding, or there must be clips (lambs) on this grounding wiring. Changing the fuses on the 380/220 V shields, the outgoing lines of which are in the zone of influence of the contact network, are carried out with the feeder switch disconnected and superimposed on the specified ground lines. Tree clearing work. Works on clearing the route from trees, which require the measures taken to prevent the fall of trees on the wires of the lines, are carried out along the way. All other work on clearing the route is carried out by order. Before felling trees, the workplace must be cleared. In winter, to quickly move away from a falling tree, two paths 5-6 m long should be laid in the snow at an angle to the line of its fall in the direction opposite to the fall. It is forbidden to climb on cut and sawn trees. The foreman is obliged to warn all members of the team about the danger of falling trees, ropes, etc. approaching before starting work. to the wires VL. In order to prevent trees from falling onto the wires, guy wires must be applied before felling. In the event of a tree falling on the wires, it is forbidden to approach it at a distance of less than 8 m until the voltage is removed from the overhead line. The sawyers must warn other workers about the impending fall of the felled tree. Standing on the side of the fall of the tree and on the opposite side is prohibited. It is forbidden to fell trees without a cut or undercut, as well as to cut through a tree. Tilt trees should be felled in the direction of their slope. It is forbidden to leave a felled and sawn tree unfelled for a break in work, or when moving to other trees. Before felling rotten and dry-resistant trees, it is necessary to test for strength, and then make a notch. It is forbidden to cut down these trees. It is forbidden to fell trees in groups with preliminary sawing and felling using the fall of one tree onto another. First of all, rotten and charred trees should be dumped. Works with the use of lifting machines and mechanisms in the security zones of overhead lines, operating electrical installations and on the territory of the power supply area. When working with the use of hoisting machines in existing electrical installations, persons responsible for the safe movement of goods by cranes must be certified engineers and have a responsible certificate. The appointment of such a person should be recorded in the order in the line "separate instructions". Work within the buffer zone with the use of lifting machines and mechanisms must be carried out along the way. The foreman, when working with disconnection and grounding of the overhead line, must have group V. The driver, who is on the staff of the power supply distance, must have group II. The movement of lifting machines with a retractable telescope or a raised boom is only permitted within the workplace without load and without people in the lifting part. When working with the use of hoisting machines within the security zone of the line under voltage, these machines must be grounded to the inventory grounding conductor with a copper portable grounding. Grounding installation is not required for the share of crawler machines. In case of accidental contact of the working body of the machine with the wire of the live line, or the occurrence of an electric discharge between them, it is prohibited until the voltage is removed from the line or the working body is removed to a safe distance, while standing on the ground, touching the machine, climb it or leave it. If, as a result of contact, the car catches fire, allowing you to stay in it, the driver must, without holding hands on parts of the car, jump to the ground on both feet. You can move away from the car until the tension is removed from the line only in small steps, not exceeding the length of the foot. Installation and operation of boom lifting mechanisms directly under the wires of overhead lines, under voltage is prohibited. It is forbidden to install a telescopic tower (hydraulic lift) inside the corner formed by the wires when working on corner work related to the replacement of insulators, wires or equipment repair. Safety measures for detecting sagging or broken wires and other damage to electrical installations. Any wires that are sagging or broken and lying on the ground, ballast prism or sleepers are a danger to life. They should be considered energized. Do not approach them at a distance of less than 8 m, and also allow unauthorized persons to approach them. All necessary measures should be taken to protect the dangerous place, involving for this purpose employees of all departments of railway transport. It is necessary to report the incident to the power supply area or, using any type of communication, to the energy dispatcher and then act according to their instructions. An electrician who finds himself at a distance of less than 8 m from broken wires lying on the ground must leave the danger zone in small steps not exceeding the length of the foot. All work to eliminate the detected damage to electrical installations must be carried out in compliance with the requirements of the instructions. When a ground fault is detected, it is forbidden to approach the fault location at a distance of less than 4 m in closed switchgear and less than 8 m in open switchgear. Approaching this place at a closer distance is allowed only for operations with switching equipment to eliminate ground faults, as well as, if necessary, providing first aid to the victims. In these cases, it is imperative to use both basic and additional electrical protective equipment. Electricians should remember that after the disappearance of voltage from the electrical installation, it can be re-applied without warning. Work at height. Works at a height of 1 m or more from the surface of the ground or floors are classified as works performed at heights. In the performance of these works, measures must be taken to prevent the fall of the worker from a height. Work performed at a height of more than 5 m from the ground surface, ceiling or working flooring of sheets, scaffolds, in which the main means of protection against falling from a height is a safety belt, are considered climbing. When working on structures under which there are live parts under voltage, repair devices and tools are tied to prevent them from falling. It is forbidden to use in these cases assembly belts from a metal chain. The electrician must know the rules of first aid, be able to practically provide first aid to the victim. In the event that an employee is injured, poisoned, or suddenly ill, the electrician is obliged to provide first aid to the victim, organize his delivery to the nearest medical facility, and report to the shop manager. 4. Safety requirement upon completion of work After the complete completion of work, the workplace is put in order, accepted by the responsible manager, who, after the withdrawal of the brigade, the foreman, signs the order for the completion of work and hands it over to the operational staff or, in the absence of the latter, leaves it in the folder of current orders. If the responsible manager has not been appointed, then the order for the operational personnel is handed over by the work foreman. The outfit can be closed only after inspecting the equipment and places of work, checking the absence of people, foreign objects, tools and with proper cleanliness. Closing of the order is carried out after the following are sequentially performed:
The equipment can be turned on only after the order is closed, after obtaining permission from the energy manager. The responsible manager, or the foreman, in case of work performed within the boundaries of the station, must make an entry in the CCS log about the completion of work. The responsible manager, the work foreman, upon arrival at the EHS, must submit a work permit (close the order), report on the amount of work performed to the head of the EHS, install protective equipment and mounting devices at the storage site. 5. Safety requirements in emergency situations Recovery work in emergency cases, as well as short-term, urgent work to eliminate such equipment malfunctions that can lead to an accident, is allowed to be carried out without a work order, followed by recording in the operational log from the notification of energy dispatchers. In the event of a break in all means of communication with the energy dispatcher, work on overhead lines, transformer substations, cable lines and related devices can only be carried out to eliminate damage that threatens the safety of train traffic, as well as to release the victims. The work in such cases may be of various categories depending on the specific conditions, but all of them must be carried out under the supervision of a person with a qualification group V. A person with a qualification group V, who has assumed the responsibility of a manager, must comply with all the requirements of this instruction, as well as measures to ensure the safety of workers. Disconnectors and other switching devices disconnected without the order of the energy dispatcher can be turned on by the work manager only if communication with the energy dispatcher is not restored. It is forbidden to turn on disconnectors and other switching devices that are in the off position until the moment of interruption of communication with the energy dispatcher. As soon as possible, the work manager is obliged to notify the energy dispatcher about what happened and the measures taken. See other articles Section Occupational Safety and Health
