B. Cut off the circuit: If you get an electric shock due to touching the wire scraped from the ground during an outing or construction, you can cut off the wire with a big knife, axe and shovel with a dry wooden handle to interrupt the current.
C. Connecting wires: If a person's body is knocked down due to contact with drooping wires, and the wires are closely connected with the body, and there is no power switch nearby, rescuers can stand on dry wood or plastic and connect the wires touching the person's body with dry wooden sticks, shoulder poles, bamboo poles, walking sticks and other insulators.
D. Pull away the electrocuted person: If the electrocuted person's hand is closely connected with the wire and cannot be pulled away, a large dry wooden stick can be used to pull the electrocuted person away from the electrocuted place.
People who get an electric shock are often delirious after leaving the power supply, and the rescuer should immediately carry out the next rescue. Loosen the collar and flat belt of the coat that affects breathing, make it lie on your back, tilt your head back, remove foreign bodies from your mouth, take off your dentures, and keep the respiratory tract unobstructed. If breathing stops and the carotid artery can't feel the pulse, mouth-to-mouth artificial respiration and chest external heart massage should be carried out immediately, and they should be carried out persistently until the injured person wakes up or becomes stiff, until the injured person wakes up or becomes stiff and dead. In the process of cardiopulmonary resuscitation, we should try our best to get in touch with nearby hospitals in order to strive for better rescue conditions for the wounded. The same emergency measures should be taken for the wounded injured by lightning.
