In our life, we are always exposed to electricity, which brings us a lot of convenience. However, if we don’t know the knowledge of safe use of electricity, coupled with carelessness at ordinary times, it is easy to cause electric shock. However, in case of electric shock, how to give first aid? Let’s talk about the first aid measures for electric shock. Don’t just read it!
Generally, most of the electric shocks people encounter are 220 V civil power or 380 V industrial power, rather than high-voltage power. If you get an electric shock and there is no rescue nearby, you need to calm down and rescue yourself. Because in the first few seconds after the electric shock, in the state of mild electric shock, people’s consciousness is not lost, rational and orderly judgment and disposal is the key to successful liberation. After electric shock, it doesn’t attract people as usual. It’s just because alternating current can cause continuous muscle spasm and contraction, so after electric shock, there will be a phenomenon of grasping the power supply, and the more you grasp, the tighter you are. At this time, the person with electric shock can quickly grasp the insulation of the wire with another free hand, and pull the wire out of the hand to release the electric shock state. If the electric appliance is fixed on the wall when the electric shock occurs, you can use the foot force to push against the wall and the body falls backward at the same time, and get rid of the power supply with the help of the body weight and external force. Those who can get rid of themselves will not have the sequelae such as deafness, vision disorder, menstrual disorder and mild personality change.
The method is as follows:
1. Turn off the power supply: if the electric shock occurs at home, the method of unplugging the power socket, turning off the power switch and opening the main switch of the power supply can be adopted to cut off the current.
2 cut off circuit: if electric shock is caused by touching the wire on the ground during field outing and construction, the wire can be cut off with a large knife, axe, spade with a dry wooden handle to cut off the current.
3. Open the electric wire: if the body of a person is knocked down because it touches the sagging electric wire, the electric wire is closely connected with the body, and the power switch cannot be found nearby, the rescuer can stand on the dry wooden board or plastic insulation, and use the dry wood stick, shoulder pole, bamboo pole, walking stick and other insulation to open the electric wire that contacts the body of a person.
4. Open the person with electric shock: if the hand of the person with electric shock is closely connected with the electric wire and cannot be lifted off, a large dry wooden stick can be used to pull the person with electric shock away from the electric shock.
After the electric shock is removed from the power supply, the rescuer should immediately carry out the next rescue. Loosen the collar and belt of the coat that affect breathing, make it lie on the back with the head back, remove the foreign matters in the mouth and remove the denture to keep the respiratory tract unobstructed. If it is found that the breathing stops and the carotid artery can not touch the pulsation, mouth to mouth artificial respiration and chest external heart massage shall be carried out immediately, and it shall be carried out unremittingly until the wounded is awake or appears dead, until the wounded is awake or appears dead, or until the dead spot. In the process of cardiopulmonary resuscitation for the wounded, we should try to get in touch with the nearby hospital so as to obtain better rescue conditions for the wounded. The same first-aid measures shall be taken for the wounded injured by lightning.
Baibai safety net suggests that, in normal times, electrical equipment must be connected to zero and have protective grounding device, and regular inspection shall be carried out to ensure its safety and reliability, and it is not necessary to use poor, worn-out and damaged wires and electrical equipment.
