(2) the basic ways to disconnect from the power supply are as follows:
A) pull the knife of the power switch near the accident, or pull out the power plug to cut off the power supply.
B) use dry insulating wood stick, bamboo pole, cloth tape and other things to pull the power cord away from the person who is shocked or pull the person who is shocked away from the power supply.
C) if necessary, use insulating tools (such as electrician's pliers with insulating handle, wood handle axe and hoe) to cut off the power line.
D) the rescuer can wear gloves or wrap dry clothes, scarves, hats and other insulating articles on his hands to drag the person who gets electric shock away from the power supply.
E) if the electric shock victim's fingers are wound on his body due to spasm, the rescuer shall first use a dry board to insert the electric shock victim's body and insulate it from the ground to cut off the incoming current, and then take other measures to cut off the power supply.
F) if the person who gets an electric shock touches the live high-voltage wire which is broken and falls on the ground, and before it is confirmed that the line is not electrified, the rescue personnel shall not enter the range of 8-10 meters of the place where the electric shock occurs, so as to prevent the step voltage from getting an electric shock. Rescue personnel entering the area shall wear insulating boots or temporary feet close to the person who is shocked by electric shock. After the electric shock is separated from the live wire, it shall be taken to 8-10 meters away immediately to start the first aid of electric shock. Only when it is confirmed that the line has no electricity, can the first aid be given on the spot after the electric shock person leaves the electric shock wire.
③ precautions to be taken when removing the person from the power supply:
A) before insulation measures are taken, the rescuer shall not directly touch the skin and wet clothes of the electric shock victim.
B) it is strictly forbidden for the rescuer to push, pull or touch the person with electric shock directly by hand. The rescuer shall not use metal or other objects with poor insulation performance (such as wet wooden stick, cloth belt, etc.) as rescue tools.
C) in the process of pulling the electric shock person out of the power supply, the rescuer should operate with one hand, which is safer for the rescuer.
D) when the person with electric shock is in the high position, measures shall be taken to prevent the person from falling to the ground or dying (secondary injury by electric shock) after leaving the power supply.
E) in case of electric shock accident at night, temporary lighting after power cut off shall be considered to facilitate rescue.
④ rescue measures for those who are not unconscious due to electric shock:
The person with electric shock should be allowed to lie down and rest in a dry, warm and ventilated place, and the person should be sent for close observation. At the same time, the doctor should be invited to come or be sent to the hospital for diagnosis and treatment.
⑤ the person who is shocked has lost consciousness, but there are still rescue measures for heartbeat and breath:
It should be comfortable lying on the ground, unbuttoned to facilitate breathing, not surrounded by people, keep the air circulation, keep warm in cold days, and immediately ask the doctor to come or send to the hospital for diagnosis and treatment. If it is found that the person with electric shock has dyspnea or cardiac arrhythmia, immediately carry out respiration and external chest cardiac compression.
⑥ first aid measures for the 'feigned dead':
When it is judged that the respiratory and heart rate of the electrocuted person stops, it should be rescued immediately according to cardiopulmonary resuscitation. The method is as follows:
A) unobstructed airway. First, remove foreign matters from the mouth. Make the person lying on his back in a flat and hard place to quickly untie his collar, scarf, tights and trouser belt. If there are foreign bodies such as food, denture and blood clot in the mouth of the person with electric shock, turn his body and head at the same time, quickly insert them from the corner of the mouth with one finger or two fingers, take out the foreign bodies from the mouth, and pay attention to prevent the foreign bodies from being pushed into the throat during the operation. Secondly, the airway was unblocked by raising the head and cheek. During the operation, the rescuer puts one hand on the forehead of the person who is shocked, and the fingers of the other hand lift the chin and jaw upward,
The two hands work together to push the head back, and the tongue base will lift naturally, and the airway will be unblocked. In order to make the head of the person with electric shock recline, appropriate thickness of articles can be padded under the neck, but it is strictly prohibited to use pillows or other articles to pad under the head of the person with electric shock.
B) mouth to mouth (nose) artificial respiration. Make the patient lie on his back, loosen his clothes and belt, clear the sputum, vomit, blood clot and mud in the mouth of the injured, and keep the respiratory tract unblocked. The rescuers hold the jaw of the injured person with one hand, so that his head is as far back as possible, hold the nostril of the injured person with the other hand, take a deep breath, blow hard on the mouth of the injured person, then leave the mouth of the injured person immediately, and release the hand holding the nostril at the same time. The blowing force should be moderate, and the frequency should be 16-18 times per minute.
C) external chest compression: lie the injured on the ground or on a hard bed, kneel or stand on the side of the injured, face the injured, place the palm of the right hand on the lower part of the injured's sternum and xiphoid process, place the left hand on the right hand, press the lower part of the sternum backward to the spinal column with the weight of the upper body, then relax the wrist, and squeeze 60-80 times per minute. During external chest compression, the head should be lowered to facilitate venous blood flow. If the injured person stops breathing at the same time, artificial respiration should also be carried out during external chest compression. Usually do four chest compressions and one artificial respiration
