Summer vacation safety has always been the focus of social attention. The following is the detailed information of safety education in summer vacation that I have carefully arranged for you. Welcome to reading.
Outdoor lightning protection measures
1, because of the lightning between the cloud and the ground, it is selective. Generally tall objects and their tips are easily struck by lightning. So please stay away from outdoor towers, chimneys, telephone poles and other high objects, and don't hide under big trees or go to isolated sheds and huts to shelter from the rain.
If you have nowhere to hide outdoors, you can hide at 45? Angle with lightning protection device. Inside the corner cone, this is the lightning rod safety protection zone, but don't get close to these buildings or structures.
3. In the wilderness of the suburbs, find a low-lying place, stand on a dry, preferably insulated object, squat down and put your feet together, so that there will be no potential difference between your legs.
4. In order to prevent the influence of contact voltage, don't touch any metal objects outdoors, such as wires, steel pipes, rails and other conductive objects.
5. When you are in the wild mountain, you'd better hide in the cave and try to hide in the depths of the cave. Keep your feet together and don't touch the cave wall.
6. In thunderstorm weather, don't go to activities near the water surface such as rivers and lakes, and go ashore as soon as possible to avoid and stay away from the water surface.
7. If you can have a car, it is safe to hide in the car with the doors and windows closed. Because the metal car shell is a very good shield. If there is a lightning strike, the metal shell will easily conduct the lightning to the earth.
Indoor lightning protection measures
1, during a thunderstorm, be sure to close the doors and windows in time to prevent the invasion of direct lightning and spherical lightning. At the same time, try to stay away from doors and windows, balconies and external walls. Otherwise, once the house is struck by lightning, you may be exposed to voltage and side lightning, which will become the discharge channel of lightning current.
2. Don't get close to or touch any metal pipes indoors, including water pipes, heating pipes and gas pipes. Special reminder not to take a bath in thunderstorm weather, especially not to use any solar water heater to take a bath.
It is also very dangerous to pull some metal wires such as iron wires indoors at will. In some lightning damage investigations, many casualties are caused by contact voltage and side lightning strike in the case of complaints.
Don't use any household appliances in the room, including TV, computer, telephone, refrigerator, washing machine and microwave oven. In addition to the power cord, these appliances will also have feeders introduced by antennas, and computers and telephones will also have signal wires. Overvoltage generated by lightning electromagnetic simulation will burn out equipment through power lines, antenna feeders, signal lines, etc., and some will also cause fires. If people touch and approach the equipment, they will also get injured and burned. The best way is not to use these appliances, and unplug all power supplies and signal lines.
4. Keep the indoor floor dry. And good grounding of various electrical appliances and metal pipes. If the indoor floor or wires are wet, lightning current may leak and hurt people. Indoor metal pipes are not well grounded, and the grounding resistance is very high. If the lightning current cannot discharge to the earth smoothly, it will break through the air gap and discharge to the human body, causing casualties.
