1.6. Dangerous actions:
1.7. When performing work on the repair of electrical equipment, employees must receive personal protective equipment:
2. Labor protection requirements before starting work 2.1. Put on overalls and other personal protective equipment established for this type of work. Clothing should be buttoned up and tucked in, trousers should be over shoes, cuffs fastened, hair tucked under a tight-fitting headdress. Protect the skin from the action of solvents and oils with protective ointments (PM-1 or HIOT-6), pastes (IER-1, IER-2, Airo). 2.2. Check that the tools and devices used during work are in good condition, not worn out and meet safe working conditions. Non-mechanized tool 2.2.1. Wooden handles of tools must be made of seasoned hard and tough wood, smoothly processed, their surface must not have potholes, chips and other defects. The tool must be properly fitted and securely fastened. Percussion tools (hammers, sledgehammers, etc.) must have oval handles with a thickened free end. The console on which the instrument is mounted must be wedged with a completed mild steel wedge. On the wooden handles of pressure tools (files, chisels, etc.) in the places of interface with the tool, metal (bandage) rings must be mounted. 2.2.2. Percussion instruments (chisels, cross-cuts, barbs) should not have cracks, burrs, work hardening; the occipital part of them should be smooth, free of cracks, burrs and bevels.

electrified tool 2.2.13. All power tools and electrical appliances must have closed and insulated inputs (contacts) of the supply wires. In order to protect against mechanical damage and moisture, the wires of power tools and electrical appliances must be protected by rubber hoses and terminated with a special plug. 2.3. Check the power tool:
If you feel at least a weak action of the current, disconnect the power tool from the mains and hand it over for repair. 2.4. Connect the power tool using plug-in connections. At the same time, check the contacts of the forced and leading inclusions of the ground wire (for power tools operating under voltage above 42 V). 3. Labor protection requirements during work 3.1. To avoid a short circuit in the electrical system of the machine during its repair, use the electrical diagram provided in the technical description and operating instructions for the machine or equipment. 3.2. Control and adjustment work performed in the workshop with the engine of the machines running (checking the operation of the generator, adjusting the relay-regulator, etc.) should be carried out at a special post equipped with exhaust gases from the room to the atmosphere. 3.3. When installing (removing) the starter and the instrument panel, first disconnect the wire connected to the ground from the battery. 3.4. When working and adjusting electrical equipment on a tractor (machine), in order to avoid a short circuit, use a tool with insulated handles. 3.5 When working near the fan impeller, remove the drive belt from it to avoid injury. 3.6. If it is necessary to perform work under the machine, place it away from possible traffic, place safety stops under the wheels. When working under the machine, use a wooden bed, placing it along the axis of the machine. 3.7. When inspecting the machine, use a portable lamp with a voltage of no higher than 42 V, and when working in an inspection ditch - no higher than 12 V. 3.8. Do not check the state of charge of the batteries by short-circuiting the terminals. 3.9. Do not use ladders when working with power tools. 3.10. Do not pass the power tool on to another person. 4. Labor protection requirements in emergency situations 4.1. When checking the operability of electrical equipment after repair or replacement of elements, if there is a smell of burning insulation, disconnect the electrical equipment from the battery using the mass button. 4.2. If the machine catches fire as a result of a short circuit, disconnect the electrical equipment from the battery with the mass button and take measures to extinguish the fire. 4.3. In case of accidents with people, provide them with first aid, immediately notify the work manager, maintain the situation in which the accident occurred, if this does not threaten the life and health of others and does not violate the technological process, until the arrival of persons investigating the causes of the accident. 4.4. In case of electric shock, release the victim from the current as soon as possible, because. the duration of its action determines the severity of the injury. To do this, quickly turn off the part of the electrical installation that the victim touches with a knife switch or other disconnecting device. 4.5. If it is impossible to quickly turn off the electrical installation, it is necessary to separate the victim from live parts: 4.5.1. When releasing the victim from live parts or wires with voltage up to 1000 V, use a rope, stick, board or other dry object that does not conduct electric current, or pull the victim by the clothes (if it is dry and lags behind the body), for example, by the skirts of a jacket or coat, behind the collar, while avoiding touching the surrounding metal objects and parts of the body of the victim, not covered by clothing. 4.5.2. If the victim touches the wire that lies on the ground, then before approaching him, place a dry board, a bundle of dry clothes or some kind of dry, non-conductive stand under your feet and separate the wire from the victim with a dry stick, board. It is recommended to operate with one hand if possible. 4.5.3. If the victim convulsively squeezes one current-carrying element (for example, a wire) in his hand, separate the victim from the ground by slipping a dry board under him, pulling his legs off the ground with a rope or pulling him by his clothes, while observing the safety measures described above. 4.5.4. When pulling the victim by the legs, do not touch his shoes or clothing unless your hands are insulated or poorly insulated, because. shoes and clothes may be damp and conduct electricity. To isolate hands, especially if it is necessary to touch the body of the victim, not covered by clothing, put on dielectric gloves, if they are not available, wrap your hands with a scarf or use any other dry clothing. 4.5.5. If it is not possible to separate the victim from live parts or disconnect the electrical installation from the power source, then chop or cut the wires with an ax with a dry wooden handle or bite them with a tool with insulated handles (pliers, wire cutters). Cut and cut the wires phase by phase, i.e. each wire separately. You can also use an uninsulated tool, but you need to wrap its handle with a dry woolen or rubberized cloth. 4.5.6. When separating the victim from live parts with voltages above 1000 V, do not approach the victim closer than 4 - 5 m indoors and 8 - 10 m outdoors. To release the victim, put on insulating gloves and insulating boots and operate only with an insulated rod or tongs rated for the appropriate voltage. 4.6. If the victim is conscious, but frightened, confused and does not know that in order to free himself from the current he needs to get off the ground, with a sharp shout of "jump" make him act correctly. Providing first aid 4.7. Electric shock. After releasing the victim from the action of electric current, lay him on a bed and cover it warmly, quickly determine the nature of the required first aid within 15 - 20 seconds, arrange for a doctor to be called and take the following measures: 4.7.1. If the victim is breathing and conscious, put him in a comfortable position, unfasten his clothes. Before the doctor arrives, provide the victim with complete rest and access to fresh air, while monitoring his pulse and breathing. Do not allow the victim to get up and move before the arrival of the doctor, and even more so continue to work; 4.7.2. If the victim is unconscious, but his breathing and pulse are stable, keep an eye on them, let him smell ammonia and spray his face with water, ensuring complete rest until the doctor arrives; 4.7.3. In the absence of breathing, as well as infrequent and convulsive breathing, or cardiac arrest (lack of pulse), immediately perform artificial respiration or chest compressions. Begin artificial respiration and heart massage no later than 4-6 minutes from the moment of cessation of cardiac activity and breathing, because. after this period, clinical death occurs. Never bury the victim in the ground. 4.8. Perform artificial respiration "from mouth to mouth" or "from mouth to nose" as follows. Lay the victim on his back, unfasten clothing that restricts breathing, place a roller of clothing under the shoulder blades. Ensure that the airway is clear, which may be obstructed by a sunken tongue or foreign material. To do this, tilt the head of the victim as much as possible, placing one hand under the neck and pressing the other on the forehead. In this position, the mouth usually opens, and the root of the tongue moves to the back of the larynx, providing airway patency. If there is foreign matter in the mouth, turn the victim's shoulders and head to the side and clean the mouth and throat with a bandage, handkerchief or shirt edge wrapped around the index finger. If the mouth does not open, then carefully insert a metal plate, tablet, etc. between the back teeth, open your mouth and, if necessary, clean your mouth and throat. After that, kneel down on either side of the victim’s head and, keeping the head thrown back, take a deep breath and, pressing your mouth tightly (through a handkerchief or gauze) to the victim’s open mouth, blow air into him strongly. At the same time, cover the nose of the victim with the cheek or fingers of the hand on the forehead. Make sure that the air enters the lungs and not the stomach, this is revealed by the distention of the abdomen and the lack of expansion of the chest. If air has entered the stomach, remove it from there quickly by briefly pressing the area of \uXNUMXb\uXNUMXbthe stomach between the sternum and navel. Take measures to free the airways and repeat the blowing of air into the lungs of the victim. After blowing in, release the mouth and nose of the victim for free exit of air from the lungs. For a deeper exhalation, lightly press on the chest. Perform each air injection after 5 seconds, which corresponds to the rhythm of your own breathing. If the jaws of the victim are compressed so tightly that it is not possible to open the mouth, then perform artificial respiration according to the mouth-to-nose method, i.e. blow air into the victim's nose. When the first spontaneous breaths appear, time the artificial breath to coincide with the beginning of the spontaneous breath. Perform artificial respiration until the victim's deep and rhythmic (own) breathing is restored. 4.9. Perform external heart massage in case of cardiac arrest, which is determined by the absence of a pulse, dilated pupils and cyanosis of the skin and mucous membranes. When performing an external massage of the victim’s heart, lay the victim on his back on a hard surface or place a board under him, free the chest from clothes and raise his legs by about 0,5 m. 3 - 4 cm above this place along it is determined by the point of pressure. Place the part of the palm adjacent to the wrist joint on the place of pressure, while the fingers should not touch the chest, place the palm of the second hand at a right angle on the back of the palm of the first hand. Make a quick (push) and strong pressure on the sternum and fix it in this position for about 0,5 s, then quickly release it, relaxing your hands, but do not take them away from the sternum. Apply pressure approximately 60 - 80 times per minute. Massage the heart until your own (not supported by massage) regular pulse appears. 4.10. If it is necessary to simultaneously perform artificial respiration and heart massage, the procedure for conducting them and the ratio of the number of injections to the number of pressures on the sternum is determined by the number of persons providing assistance: 4.10.1. If one person is helping, then perform artificial respiration and heart massage in the following order: after two deep breaths, do 15 chest compressions, then again two deep breaths and 15 chest compressions, etc.; 4.10.2. If you provide assistance together, then one makes one blow, and the second after 2 s produces 5-6 pressures on the sternum, etc. 4.11. Perform artificial respiration and heart massage until the body's vital functions are fully restored or until a doctor arrives. 4.12. Injuries. Lubricate abrasions, injections, minor wounds with iodine or brilliant green and apply a sterile bandage or seal with a strip of adhesive plaster. For a large wound, apply a tourniquet, lubricate the skin around the wound with iodine and bandage it with a clean gauze bandage or a sterile bandage from an individual package. If there is no bandage or bag, take a clean handkerchief or cloth and drop iodine on the place that will lie on the wound to make a stain larger than the wound, and apply the stain on the wound. Apply the bandage so that the blood vessels are not squeezed, and the bandage is kept on the wound. In case of injury, give a tetanus toxoid injection in a medical institution. 4.13. Stop bleeding. When bleeding stops, lift the injured limb up or position the injured part of the body (head, torso, etc.) so that they are elevated and apply a tight pressure bandage. If during arterial bleeding (scarlet blood flows in a pulsating stream) the blood does not stop, apply a tourniquet or twist. Tighten the tourniquet (twist) only until the bleeding stops. Mark the time of applying the tourniquet on a tag, piece of paper, etc. and fasten it to the harness. The tourniquet is allowed to be kept tightened for no more than 1,5 - 2 hours. In case of arterial bleeding, take the victim to a doctor as soon as possible. Transport it in a comfortable and, if possible, fast vehicle, always with an accompanying person. 4.14. bruises. For bruises, apply a tight bandage and apply cold soaks. In case of significant bruises of the torso and lower extremities, take the victim to a medical facility. Bruises in the abdomen lead to ruptures of internal organs. Immediately take the victim to a medical facility at the slightest suspicion of this. Do not let such patients drink and eat. 4.15. Bone fractures. For a closed fracture, place the limb in a comfortable position, while handling it carefully, avoid sudden movements, and apply splints. Put splints on both sides, while putting cotton under the splints so that the splints do not touch the skin of the limbs, and be sure to capture the joints above and below the fracture sites. Tires can be worn over clothing. In case of an open fracture, stop the bleeding, lubricate the edges of the wound with iodine, bandage the wound and apply splints, bandage the broken leg to the healthy leg, and the arm to the chest. In case of a fracture of the collarbone and scapula, put a tight cotton roll into the axillary region of the injured side, and hang your hand on a scarf. If your ribs are broken, wrap your chest tightly or with a towel as you exhale. If the spine is fractured, carefully place the victim on an ambulance stretcher, boards or plywood, make sure that the torso does not bend (to avoid damage to the spinal cord). In case of broken bones, take urgent measures to deliver the victim to the nearest medical facility. 4.16. Dislocations. In case of dislocation, ensure the immobility of the injured limb, apply splints without changing the angle that formed in the joint during dislocation. Dislocations should be set only by doctors. When transporting the victim to a medical facility, place the victim on a stretcher or in the back of a car, and cover the limb with rollers from clothes or pillows. 4.17. Burns. In case of a thermal burn, remove clothing from the burned area, cover it with sterile material, put a layer of cotton wool on top and bandage it. Do not touch burns, puncture blisters, or tear off pieces of clothing stuck to burns while treating. Do not lubricate the burnt surface with ointments and do not cover with powders. In case of severe burns, take the victim to the hospital immediately. 4.17.1. In case of an acid burn, remove clothing and thoroughly for 15 minutes. rinse the burned area with a stream of water, then rinse with a 5% solution of potassium permanganate or a 10% solution of baking soda (a teaspoon in a glass of water). After that, cover the affected areas of the body with gauze soaked in a mixture of vegetable oil and lime water, and bandage. 4.17.2. In case of alkali burns, the affected areas within 10-15 minutes. rinse with a stream of water, and then with a 3 - 6% solution of acetic acid or a solution of boric acid (a teaspoon of acid in a glass of water). After that, cover the affected areas with gauze soaked in 5% acetic acid solution and bandage. 4.18. Frostbite. In case of frostbite of the XNUMXst degree (skin is edematous, pale, cyanotic, loses sensitivity), bring the victim into a cool room and rub the skin with a dry, clean cloth until redness or a feeling of warmth, lubricate with fat (oil, lard, boric ointment) and apply an insulated bandage. Then drink hot tea to the victim and transfer to a warm room. With frostbite II - IV degree (bubbles with bloody fluid appear on the skin, and it becomes purple-cyanotic color - II degree; layers of the skin and underlying tissues become dead, the skin becomes black - III degree; complete necrosis of the skin and tissues - IV degree) apply a dry bandage on the affected skin, let the victim drink hot tea or coffee and immediately send to the nearest medical facility. 4.19. Heat and sunstroke. At the first signs of malaise (headache, tinnitus, nausea, rapid breathing, intense thirst, sometimes vomiting), lay the victim in the shade or bring into a cool room, free the neck and chest from tight clothing; if the victim is conscious, give cold water to drink; moisten the head, chest and neck periodically with cold water, let's sniff ammonia. If the victim is not breathing, perform artificial respiration according to paragraph 4.10 of this instruction. 4.20. Poisoning by pesticides, mineral fertilizers, preservatives and their decay products. First of all, remove the victim from the contaminated area and free from clothing that restricts breathing and respiratory protection. Take first aid measures aimed at stopping the entry of poison into the body:
Do not give castor oil as a laxative. If possible, bring the victim to a warm room. When unconscious, use heating pads, but with great care, in case of poisoning with DNOC, nitrafen, sodium pentachlorophenol and sodium pentachlorophenolate, heat is contraindicated, perform cold procedures: cool baths, wet rubdowns, cold compresses, ice packs. If breathing is weakened, let's smell ammonia, in case of cessation of breathing or cardiac activity, perform artificial respiration or closed heart massage. In the presence of convulsions, exclude any irritation, give the patient complete rest. If irritating substances, such as formalin, enter the body, give the victim an enveloping agent (starch solution) to drink. Do not give milk, fats, alcoholic drinks. For skin bleeding - apply tampons moistened with hydrogen peroxide, for nosebleeds - lay the victim down, lift and tilt his head slightly, apply cold compresses to the bridge of the nose and the back of the head, insert tampons moistened with hydrogen peroxide into the nose. In case of poisoning with organophosphorus compounds, accompanied by salivation, lacrimation, constriction of the pupils, slowing of breathing, slowing of the pulse, muscle twitches, drink belladonna preparations: 3-4 tablets of besalol (becarbon) or 1-3 tablets of bellalgin. In all cases of poisoning (even mild), immediately refer the patient to a doctor or paramedic. 4.21. Poisoning with poisonous gases. If signs of poisoning appear (headache, tinnitus, dizziness, dilated pupils, nausea and vomiting, loss of consciousness), remove the victim immediately to fresh air and organize the supply of oxygen for breathing using a rubber cushion or an oxygen cylinder. In the absence of oxygen, lay down the victim, raise his legs, let him drink cold water and let's sniff cotton wool moistened with ammonia. If breathing is weak or stops, perform artificial respiration until a doctor arrives or breathing is restored. If possible and the victim is conscious, give him plenty of milk to drink. 4.22. Eye damage. In case of clogging of the eyes, rinse them with a 1% solution of boric acid, a stream of clean water or a damp cotton (gauze) swab. To do this, lay the head of the victim so that you can direct the jet from the outer corner of the eye (from the temple) to the inner. Don't rub your clogged eye. If splashes of acid and alkali get into the eye, rinse it for 5 minutes. clean water. After washing the eye, apply a bandage and send the victim to a doctor. 5. Labor protection requirements at the end of work 5.1. Hand over the power tool, protective devices, repair fund to the warehouse in the prescribed manner. 5.2. Tidy up the workplace, fold tools and fixtures, and de-energize the equipment. 5.3. De-energize equipment, turn off ventilation and local lighting. 5.4. Remove overalls and other personal protective equipment, put them in a closed cabinet; if your overalls need to be washed or repaired, put them in the pantry. 5.5. Notify the work manager about the condition of the equipment. 5.6. Follow the rules of personal hygiene. See other articles Section Occupational Safety and Health
