2. Even if the power supply is unplugged, the concentrated wires are still charged. It's best not to get too close to the wires, and try to stand under the light bulb. Because if the thunder is particularly serious, the light bulb may break, and standing under the light bulb is particularly dangerous.
3, can't take a shower, because the hot water appliance is charged. At this time, bathing may conduct electricity, which is likely to threaten life safety. It is best to unplug the water heater, and it is best not to turn on the water heater in thunderstorm weather.
4. Keep away from windows, walls, etc. And it is best not to stand barefoot on the ground. One thing to note here is that it is best not to use iron wire as a clothesline to connect the windows, which is easy to introduce lightning.
In case there is a thunderstorm outside, never hide under the big tree. This is the minimum awareness of lightning protection. In addition, you can't stay in high-rise platforms, separate huts, sentry boxes, etc. However, if there is really no place to hide, just squat down with your legs together three meters away from the tree.
Extended data:
The average current of lightning is 30,000 amps, and the maximum current can reach 300,000 amps. The voltage of lightning is very high, about 1 billion to 1 billion volts. The power of medium-intensity thunderstorm can reach10 million watts, which is equivalent to the output power of a small nuclear power plant.
In the process of discharge, due to the sudden increase of temperature in the lightning channel, the air volume expands rapidly, resulting in shock waves and strong lightning. When the charged Lei Yun is close to the protrusions on the ground, a violent discharge will occur between them. There will be strong flash and explosion roar at the scene of lightning discharge. This is the lightning and thunder that people see and hear.
