How to prevent electric shock in rainy days?
2. Don't turn on the TV, computer, VCD player, etc. Unplug all power plugs during thunderstorms and lightning to avoid personal injury and electrical damage.
3, don't stand under the light bulb, don't take a shower.
4. Try not to go out. If you have to go out, you'd better wear rubber shoes and a raincoat, which can keep out lightning.
5. Try not to open the door or open the window to prevent lightning from hitting the room directly.
6. Don't stick your head and hands out of the window when you encounter lightning in the car.
7. Stay away from trees during a thunderstorm. Try not to run in big strides. You can choose buildings to shelter from the rain. You can also take shelter from the rain in the car, because the car belongs to the metal shell, so people will not be hurt by inductive lightning, nor will they be directly hit by lightning.
8. Don't connect the wires for drying clothes and bedding to the doors and windows.
9. Don't wear wet clothes, hats, shoes, etc. Walking in a thunderstorm. For sudden lightning, the height should be lowered immediately, and the feet should be close together to reduce the harm caused by the step voltage.
10, when lightning strikes, don't get close to all power facilities, such as high-voltage line transformers.
1 1, immediately stop outdoor swimming, boating, fishing and other water activities.
12. If many people gather outdoors, don't crowd each other to prevent power from being transmitted to each other after being struck by lightning.

Emergency treatment:
1, get out of the power supply.
The first task of on-site treatment is to cut off the power supply in order to race against time.
According to the environment and conditions of the electric shock site, take the safest and quickest method to cut off the power supply or make the electric shock person leave the power supply.
Common methods are: turn off the power supply; Pick up the wire.
(1) Turn off the power? If you get an electric shock at home or near the switch, it is the simplest, safe and effective method to quickly turn off the power switch and open the main power switch.
(2) Connect the wires? Use dry wooden sticks, bamboo poles, etc. Pick the wire away from the person who gets an electric shock and fix it to prevent others from getting an electric shock.
(3) cut off the circuit? If it is not convenient to get close to the person who gets an electric shock in the wild or far away from the power switch, especially in rainy days, you can cut off the wires with insulating pliers or shovels, axes and knives with dry wooden handles 20 meters away from the scene.
(4) "Pull away" the electrocuted person? If the electrocuted person is unfortunately prone on the iron shell machine, the rescuer can put a dry wooden board or plastic board under his feet and wrap the electrocuted person with dry and insulating cloth, rope or clothes to pull it away from the power supply.
During the whole process of disconnecting the electric shock victim from the power supply, you must prevent yourself from getting an electric shock. Please note the following points:
(1) It must be strictly insulated from the person who gets an electric shock, and it is not in direct contact with the person who gets an electric shock. The selected equipment must have insulation performance. If you are not sure about the insulation performance of the equipment used, when operating, put dry wood blocks, thick plastic blocks and other insulation items under your feet to insulate yourself from the earth.
(2) When rescuing people who get an electric shock in the field in rainy days, the original insulation equipment loses its insulation performance because of being affected with damp, so we should pay more attention to it.
(3) Pay attention to the possibility of step voltage and take precautions against it. It is best to cut off the power supply 20 meters away; If you really want to get in and out of the danger zone, you must ensure that one foot touches the ground and step by step. It is absolutely forbidden to touch the ground with both feet at the same time.
2, there are signs of hypoxia to oxygen.
3. Cardiopulmonary resuscitation
(1) If the breathing is weak or irregular, or even stops, and the heartbeat still exists, mouth-to-mouth artificial respiration, chest compressions in supine position or chest compressions in prone position should be performed immediately. If possible, tracheal intubation balloon or ventilator can be used to assist breathing.
(2) If the heart stops and breathing still exists, chest compressions should be performed immediately. For patients with ventricular fibrillation, asynchronous DC defibrillation should be performed when conditions permit.
(3) Cardiopulmonary resuscitation (CPR) should be carried out immediately for patients with cardiac arrest and respiratory arrest.
4. Protect the electric burn wound on the body surface.
(1) After the skin around the body surface electric burn wound is treated with iodophor, it is covered with sterile dressing to reduce pollution.
(2) If the wound has secondary bleeding, it should be treated accordingly.
5. Symptomatic treatment
(1) Actively prevent and treat complications such as cerebral edema and acute renal failure.
(2) Correct the imbalance of water, electrolyte and acid-base.
(3) The fracture should be properly fixed.
(4) Use antibiotics to prevent infection.
(5) Patients with cardiac arrest and respiratory arrest should establish effective ventilation and oxygen supply, and recover their heartbeat or be transferred to the hospital at the same time of effective cardiac compression.
① Establishment of venous access in critically ill patients.
② Check whether there are other combined injuries, such as fracture caused by falling from a height after electric injury.
③ Monitoring vital signs.
