For protective measures in thunderstorms, safety measures to prevent lightning strikes during thunde

1. When thunder, close the doors and windows, try not to dial or answer, unplug the power supply of household appliances and metal wires that may introduce lightning such as wires and TV closed lines.

2. Leave the metal water pipes and sewer pipes connected to the roof indoors, and do not pull the wires to the windows and doors. Households should not use computers, color TVs, stereos, DVD players and other weak current equipment near the exterior wall, and it is best not to use these devices when lightning occurs.

3. Pay attention to listening, watching or checking the weather forecast on the Internet during the thunderstorm season, try not to go out when there is a thunderstorm, and take emergency precautions in advance to avoid or reduce losses caused by lightning strikes.

Safety measures to prevent lightning strikes during thunderstorms for the Safety Assessor Exam.

1. When thunder and lightning are combined, feeling the stinging pain or hair standing up is a precursor to the coming thunder and lightning, and you should avoid it immediately. If you are in an open area, you should immediately squat on the ground, put your hands on your knees, keep your chest close to your knees, and keep your head down as much as possible to reduce the risk of lightning strikes. Do not use your hands on the ground, as this will increase the range of contact between your body and the ground, increasing the risk of lightning strikes.

2. In case of thunderstorm, if you have no time to leave the tall object, you should find some dry insulation and put it on the ground, sit on it or adopt a squatting posture, and pay attention to the feet together. Keep your hands together and don't put them on the ground, and don't lie down, because the height is lowered, but the danger of "stepping voltage" increases. Water conducts electricity, so wet objects cannot be insulated.

3. When encountering a thunderstorm on the mountain, do not take shelter from the thunderstorm at the mouth of the cave, under the boulder or under the overhanging rock, because these places will become spark gaps, and the arc generated by the current passing through it can hurt people. But the deep cave is safe, and you should try to go inside. Lone trees and isolated grass huts on the top of the hill should be avoided as they are the most vulnerable to lightning strikes.

At this time, it is very dangerous to take shelter from the rain, especially if you stand under a low branch that stretches far to the sides. However, things are divided into two, if there is a dense forest in the wild, and there is no other lightning shelter for a while, then you can also use the dense forest to avoid lightning, because the chance of being struck by lightning everywhere in the dense forest is almost the same.

4. When Yu Xun Town encounters thunderstorms, stay away from railways, extended metal railings and other huge metal objects. Because it is not a direct lightning strike that can be fatal, when lightning strikes a conductor, the electrical energy is released in an instant, and the arc of electricity shot out on both sides can reach several meters. In addition, the blazing electric light causes the surrounding air to expand dramatically, and the resulting shock wave can also injure people.

Another sound from the shock wave is thunder. If heard up close, powerful sound waves can shock the eardrum and lungs, and in severe cases, can shock a person to death.

5. In case of thunderstorm, if you are in a car, train, ship and other means of transportation, it is best to stay in the means of transportation at this time. Because the body is metal and has a shielding effect, the cabin is an ideal place to shelter from lightning strikes. However, it is best not to ride horses, bicycles, motorcycles and drive in a canopy during a thunderstorm.

6. During a thunderstorm, if you are at home or in a building, you should unplug the outdoor antenna plug and power plug of the TV. Do not go close to the window, as far as possible away from the electric lights, wires, wires and other lead-in wires, in the building without lightning protection devices, avoid steel columns, water pipes and heating pipes, in order to prevent lightning current from penetrating into the human body through them.

1. Do not dial and answer, and unplug the ** wire. The phone can be used normally. But try not to pick up your phone outdoors or indoors near a window.

2. Do not turn on the TV, computer, VCD player, etc., unplug all power plugs, turn off household appliances, and unplug the power plugs to prevent lightning from invading from the power cord.

3. Don't stand under the light bulb and don't take a shower.

4. Try not to go out, if you must go out, wear rubber shoes and a raincoat can play an insulating role in lightning.

5. Regardless of indoor or car encounters thunder and lightning, try not to open the door or window, and do not stick your head and hands out of the window to prevent direct lightning strikes.

6. When the thunderstorm is large, stay away from the trees, try not to run in stride, you can choose a building to hide from the rain, but it is not advisable to choose to hide from the rain in the car.

7. Do not pull the wire of drying clothes and bedding to the windows and doors, and do not wear wet clothes, hats, shoes, etc. to walk around under heavy thunderstorms. For sudden lightning, you should immediately squat down to reduce your height, and at the same time bring your feet together to reduce the harm caused by the stride voltage.

8. When lightning strikes, do not approach all power facilities, such as high-voltage wires and transformer appliances.

9. Outdoors, stop outdoor swimming, boating, fishing and other water activities, take shelter in time, and do not stay in the open suburbs. When there is nowhere to take shelter in the open suburbs, do not run, do not carry umbrellas and other objects, try to find low-lying places (such as dirt pits) to hide, or put your feet together and squat on the spot.

1. Do not engage in activities in humid scenic spots.

2. When there is a sudden thunderstorm in the wild encounter, you should immediately search for safer buildings to avoid lightning, such as residences, public buildings, etc., or go down the mountain to seek safety.

3. Try to avoid mountain tops and high places, as well as close to big trees, cliffs, grasslands, fields and other places that are susceptible to lightning invasion.

4. Don't keep your eyes on the sky, close your eyes immediately and protect your eyes.

5. Do not stand in contact with the ground such as various electrical equipment, metal objects, hillsides, etc., and the relatively safe distance is at least 20 meters.

6. When riding a car, you can use the body as a relatively safe nest to protect yourself from lightning strikes.

For individuals and families, first of all, it is necessary to understand more about lightning protection, enhance lightning awareness, and actively take preventive measures to avoid lightning injuries. Secondly, we should use the lightning protection knowledge we have mastered to publicize and educate the people around us; During thunderstorms, when walking in the wilderness, try to leave the point of the environment, run to low-lying places or simply lie down, do not take shelter from the rain under large trees, telephone poles, elevated towers, chimneys and high-rise buildings, and do not use metal umbrellas.

For example, in order to avoid or reduce the occurrence of lightning accidents and ensure the safety of people, animals and buildings, as far as buildings are concerned, the first step is to do a good job in architectural design, and comprehensively consider lightning protection and lightning protection facilities according to the function of the building, especially to consider the potential unsafe factors such as neon lights, billboards, metal flagpoles, microwave towers and shared antennas attached to the roof outdoors; Secondly, the construction quality inspection and supervision and completion of the construction should be carried out, and the lightning protection facilities of the building should be accepted in strict accordance with the standards set by the State Department of Regulation and Fraud.
