The old, the weak, the sick, the disabled, the pregnant, the young and so on should join their relatives and friends as soon as possible.
How to prevent typhoon?
1. Don't stand by a big tree. When a typhoon comes, trees on both sides of houses or sidewalks are often damaged and blown down. When you are outside, do not stand beside the trees to prevent the damaged objects from being attacked again by the continuous strong wind.
2. Prevent electric leakage and electric shock. Typhoon is coming. If you are outside and see a wire blown off on the road, it will fall to the ground. Do not touch it with your hands or body. Water is very conductive.
3. Keep away from dangerous buildings. Every time typhoon strikes, there are always big billboards falling down, hitting things and hurting people. Remember not to stay around the outdoor billboards.
4. Drive slowly. It's better to slow down and observe the surrounding conditions closely. If you feel that you can't control the car, you should find a safe place to stop immediately. When parking, pay close attention to the left, right and top of the car to see if there is anything that may fall or fall. If the whole section of the road is covered with water, it is necessary to carefully consider whether to wade. If the accumulated water is more than half of the tires, it is not allowed to wade. 5. Pay attention to food hygiene. When the typhoon comes, the house is flooded, so we need to pad up cabinets, beds and other furniture, and try to reduce blisters. In particular, we need to put the rice, vegetables and other food on the high place, and try to cook them thoroughly before eating them. If they are soaked in water and moldy, they can't eat any more.
6. Cut off the power supply at home in time. Typhoon often accompanied by thunderstorm and strong wind, so it is necessary to cut off the power supply. If the lightning strikes the roof water heater tank and causes water leakage, the whole water heater will be scrapped. If the situation is serious, the indoor circuit will be affected.
