When working with a megohmmeter, it is forbidden to touch the live parts to which it is attached. After completion of work, it is necessary to remove the residual charge from the equipment under test by means of its short-term grounding. 3.3. It is necessary to install the stepladder firmly, checking its stability before lifting. Ladders with a height of 1,3 m or more must be equipped with a stop. The use of metal ladders in the production of measurements is prohibited. 3.4. It is forbidden to work from the top two steps of stepladders that do not have railings or stops, as well as to be on the steps by more than one person. 3.5. When measuring with electrical clamps, clamps with an ammeter installed on their working part should be used. 3.6. The measurement should be made in dielectric gloves, galoshes, glasses. Measurement on tires should be carried out from the floor, special scaffolds, stepladders. 3.7. Connection and disconnection of measuring instruments that require a break in the electrical circuit must be carried out with complete removal of the voltage. 3.8. Voltmeters, portable voltage transformers are allowed to be connected and disconnected under voltage, subject to the rules. 3.9. When working with a voltage transformer, the entire low voltage circuit must first be assembled, and then the transformer must be connected on the high voltage side. Perform work in dielectric gloves and galoshes or standing on an insulating stand. 3.10. Wires for connecting portable devices must be single-core and multi-wire with insulation corresponding to the mains voltage and a cross section of at least 2,5 mm2. 3.11. Equipment racks that have voltages greater than 42 V AC and 110 V DC should be provided with dielectric mats. 3.12. All enclosures and covers of equipment that cover 42 VAC contacts must display the electrical voltage symbol to alert service personnel to the danger of electrical shock. 3.13. Metal cases of measuring devices and casings of transformers must be grounded. 3.14. Elimination of damage and repairs on the equipment must be carried out when the voltage is completely removed from the equipment. 3.15. Measuring circuits should be assembled with the voltage removed. 3.16. The portable power tool used (soldering iron, step-down transformer) must be tested and have an inventory number, systematically and timely checked and repaired. 3.17. During an external examination of power tools and appliances, it is necessary to pay attention to the integrity of the insulation of the wires, the absence of bare current-carrying parts. 3.18. Checking for the absence of a short circuit to the case and the condition of the insulation must be carried out by a specially appointed person at least once every 1 months. 3.19. The passage between the front side of the power distribution equipment must be at least 1,2 m. There must be no foreign objects in the passage. 3.20.

Switch off the equipment using switches, a plug-in connector, cut the supply wire with a tool with insulated handles. If it is impossible to turn off the equipment quickly enough, other measures must be taken to free the victim from the action of the current. To separate the victim from current-carrying parts or wires, use a stick, board or some other dry object that does not conduct electricity, while the caregiver must stand on a dry, non-conductive place, or wear dielectric gloves. 4.4. If a fire occurs in a technical room, you should immediately start extinguishing it with the available means (carbon dioxide fire extinguishers, asbestos blankets, sand) and call the fire department. 4.5. If extraneous voltage is detected at the workplace, it is necessary to immediately stop work and report to the shift supervisor. 4.6. In the event of a power failure while working with a power tool or a break in work, the power tool must be "Unplugged". 4.7. If you detect a smell of gas, you must immediately call the emergency gas service, inform the management of the enterprise, organize the evacuation of personnel from the ATS building, do not turn on or turn off the current collectors, and ensure natural ventilation of the room. 5.
