Instructions on labor protection when working on feeder lines. Full document
Occupational Safety and Health / Standard instructions for labor protection Safe Operation 1. General requirements for labor protection 1.1. This instruction has been developed on the basis of the requirements of DNAOP 5.2.30-1.06-98 "Safety rules during work on overhead communication lines and wire broadcasting" and DNAOP 1.1.10-1.04-01 "Rules for safe work with tools and devices". 1.2. Persons who have reached the age of 18, have passed a medical examination, have been trained in safe working methods and have a safety qualification group of at least III are allowed to work on overhead communication lines and wire broadcasting. 1.3. Organization of work on feeder lines: 1.3.1. Work on feeder lines with voltage up to 240 volts inclusive is carried out according to the oral order of the head of the workshop, section, brigade. 1.3.2. Work on feeder lines of the second class with a rated voltage of more than 240 volts inclusive is carried out by written order of the head of the workshop, section, team, and only after removing the voltage from the line. 1.3.3. Work on feeder lines of class I (over 360 volts) is organized according to a permit. 1.4. For safe work on overhead lines of any voltage, it is imperative to use proven and tested electrical protective equipment - dielectric gloves and galoshes, voltage indicators, tools with insulating handles. 1.5. All work on the radio lines is carried out in overalls with sleeves buttoned at the hands, and in a headgear (helmet). 1.6. The use of dielectric galoshes when working on feeder lines with a voltage of 120 and 240 volts in wet weather, as well as in any weather when working on an iron roof and on poles equipped with lightning rods, is mandatory. 1.7. Connecting headphones to the wires of the feeder lines is not allowed. When working with subscriber circuits, it is allowed to use headphones, the case of which is made of insulating material. 1.8. Covering the ice from the wires of class I lines should be done after the voltage is removed. 1.9. When working on radio lines, in order to prevent accidents, the safety requirements set forth in this manual must be strictly observed. Failure to comply with these requirements is considered as a violation of production discipline. The perpetrators are held accountable in accordance with applicable law. 2. Labor protection requirements before starting work 2.1. The installer working on the second class feeder line must provide protection against the action of hazardous factors at the work site. 2.2. With the team method of work, the responsible manager, taking into account dangerous factors, must instruct the members of the team on the order of work, precautions, and also make sure that workers are provided with all the necessary protective equipment. 2.3. The foreman, in whose name a permit or work permit for work with increased danger has been issued, is obliged to personally check in the control room that the voltage has been removed from the line. The disconnection of the line is confirmed by posting a poster "DO NOT TURN ON. PEOPLE WORK". The number of posters posted on the switch should correspond to the number of teams simultaneously working on the line. 2.4. Before starting work on radio lines in places of approach and intersection with overhead power lines, you must use the indicator to make sure that there is no dangerous voltage on the radio wires. Before checking the absence of extraneous voltage on a rusty wire, it is necessary, wearing dielectric gloves, to clean the place of touching it with an indicator from rust. In addition, on class 240 feeder lines with voltages above XNUMX volts and class XNUMX feeder lines, make sure that the transmission voltage at the feeder is turned off. 2.5. Feeder lines with a voltage of over 240 volts, work on which is carried out with the obligatory shutdown of the radio broadcast voltage, must be short-circuited on both sides of the work site and grounded from the side of the possible occurrence of dangerous voltage. The cross section of the flexible copper wire for grounding must be at least 16 mm2. As a grounding conductor, it is necessary to use a metal pin driven into the ground to a depth of 0,5 - 0,9 m. 3. Labor protection requirements during work 3.1. Work on feeder radio transmission lines with a voltage of 120 volts is allowed to be carried out under voltage, but subject to the obligatory use by the fitter of a tool with insulating handles or dielectric gloves. 3.2. On feeder lines with a voltage of 240 volts, it is allowed to work under voltage with a tool with insulating handles with the obligatory use of dielectric gloves. 3.3. In the case of the joint location of feeder lines with a voltage of 120,240,340 volts and above on pole or rack lines, it is allowed to work with fittings and transformers of radio broadcasting circuits with a voltage of 120 and 240 volts without removing voltage from lines of 340 volts and above, if the wires of feeder lines of 340 volts and above are located above wires of 120 and 240 volts on pole lines by at least 1 m, and on rack lines by at least 1,7 m, and with the obligatory condition that these works are not related to suspension, adjustment and dismantling of wires. 3.4. Work on radio transmission lines of class I - with a rated voltage above 360 volts: 3.4.1. Works are classified as work with increased danger and are organized according to a work permit. The work permit is issued by the responsible work manager and recorded in the duty log for the control room indicating the number of the disconnected feeder, as well as the time it was turned off and on at the end of work. 3.4.2. Work on the line is carried out with the obligatory disconnection of voltage, shorting the wires of the feeder line on both sides of the place of work and their grounding. 4. Labor protection requirements at the end of work 4.1. Upon completion of work, the responsible work executor, in whose name a permit or work permit has been issued, is obliged to make sure that all work has been performed correctly, temporary jumpers and groundings have been removed, and all workers have been removed from the place of work. 4.2. The responsible executor (foreman) must close his copy of the work permit or permit, making the appropriate entries in them. 4.3. Upon arrival at the radio center, the responsible executor (foreman) must close his copy of the work permit or permit, making the appropriate entries in them, and the responsible executor must sign in the "Duty Log for the control room" about the possibility of turning on the voltage. 4.4. If the work was carried out by several teams, then it is possible to turn on the line only after all the workers responsible for the performance of the work sign in the journal, thus all posters prohibiting the inclusion will be removed from the switch. 4.5. If the work is remote from the radio center, it is allowed to turn on the feeder line by telephone message transmitted by the work producer. The text of the telephone message is recorded in the "Hardware Room Duty Log" by the person who turned off the voltage 5. Labor protection requirements in emergency situations 5.1. When working on feeder lines with a voltage of 120 V, 240 V and above, the following emergencies are possible:
5.2. Such accidents may occur: electric shock to a worker, injury to a worker, fall from a height. 5.3. Each employee who was the first to identify the threat of an emergency should immediately stop working and shake the STOP command. 5.4. The "STOP" command given by any employee must be immediately followed by all employees who heard it. The employee must immediately inform the work manager about the threat of an emergency or the occurrence of an emergency. 5.5. To eliminate the consequences of accidents, an emergency recovery team is created, security measures are taken depending on the nature and extent of damage. 5.6. If an employee is struck by an electric current, it is necessary to release the victim from the action of electric current: cut or cut the wire with any tool with an insulated handle or separate the victim from live parts using dielectric protective equipment or other insulating objects. 5.7. In case of heat stroke, the victim must be taken to a cool place (shade) and sprayed with water on the face; 5.8. When an employee is injured, apply sterile dressing material to the wound, bandage it with a bandage; 5.9. In case of any injury received during the performance of work or in emergency situations, immediately provide the victim with first aid, and if necessary, call a doctor to the victim or send him to a medical facility. 5.10. In the event of a threat of occurrence or in the event of other emergencies not directly related to the above works, act in accordance with their duties in accordance with the Accident Response Plan, or the order of the work manager.
