Radio draft of lightning protection safety education in summer

For those students who are exercising on the radio, we usually make a broadcast draft in advance before the broadcast. A good broadcast draft will bring better program effect. How to focus the broadcast manuscript? The following is my carefully compiled broadcast draft of lightning protection safety education in summer, hoping to help everyone.

1 car is an ideal place for lightning protection in summer.

If you were driving when it thundered, you should try to stay in the car. Outdoor, the car is an ideal place to avoid lightning, which is due to the faraday cage effect.

Lightning protection experts say that faraday cage is a closed metal cage, and faraday cage is charged, but its internal field strength is zero, so people in Faraday cage are safe. Therefore, cars can also be regarded as faraday cage. The car will be charged by lightning, but the people inside will not get electricity.

Avoid running in front of lightning.

Lightning protection experts say that when many people encounter lightning in the wild, their instinctive reaction is to walk quickly or even run. In fact, this is a lightning protection taboo. Because the earth may form a potential difference when it thunders, there is a "step voltage" for pedestrians (the voltage that people bear between their feet when walking on the earth with different potentials). If you walk fast or run fast, the "step voltage" is correspondingly large, and people are more likely to get injured.

When encountering lightning in the wild, you should evacuate to houses or reinforced concrete buildings with lightning protection facilities and stay away from tall chimneys, trees, iron towers, telephone poles and other objects. If it is too late to leave, don't run around. You can choose to squat in a low-lying place, with your feet together, your arms around your knees, and your head bent down to reduce the exposed area of your body and the potential difference when you touch the ground.

These places are vulnerable to lightning strikes.

1. Places with low soil resistivity, such as areas with metal deposits, river banks, intersections where underground outlets and metal pipelines are concentrated, railway hubs, railway hubs and corners of overhead transmission lines, etc.

2. Areas with high water level and special humidity, such as river beds, salt fields, reed ponds, lakes and swamps, low-lying areas and places with high groundwater level. Because the probability of water being struck by lightning is greater than that of land.

The hillside is adjacent to the paddy field.

4. Boundary parts with different resistivity (such as rocks and soil).

5. Towering buildings, such as water towers, TV towers and flagpoles.

6. Isolated and prominent buildings (structures) and trees in the wilderness.

These lightning protection essentials should be remembered.

1. Pay attention to the lightning warning issued by the meteorological department when the weather changes.

Don't stay on the floor of the building when it thunders.

Close the doors and windows when it thunders.

4, when it thunders, can't close to the building exterior wall and electrical equipment.

Don't use solar water heater when it thunders.

6. Don't enter the shack, sentry box and other low-rise buildings (structures) when it thunders.

7. Don't hide under the big tree when it thunders.

8. Don't hold an umbrella and other items in the wild when it thunders.

9. Don't work on the surface of water or at the junction of land and water when it thunders.

Radio draft of lightning protection safety education in summer II. How to classify and defend lightning warning signals?

Lightning warning signals are divided into three levels, which are represented by yellow, orange and red respectively.

(1) Lightning yellow warning signal

Standard: Lightning activity may occur within 6 hours, which may cause lightning disasters and accidents.

Defense guide:

1. The government and relevant departments should do a good job in lightning protection according to their duties.

2. Flammable, explosive and dangerous chemicals should be placed in a safe place or safety protection measures should be taken as soon as possible, and the transportation plan of the above items within the early warning period should be cancelled.

3. Pay close attention to the weather, try to avoid outdoor activities, and cancel plans for outdoor activities such as production, tourism, sports, assembly and business.

4. People who are outdoors and have no safe refuge nearby should return as soon as possible, and the playground should arrange to close outdoor facilities as soon as possible and place tourists in a safe place.

5. People in places without lightning protection detection or unqualified detection should pay special attention to strengthening prevention.

(2) Lightning orange warning signal

Standard: There is a great possibility of lightning activity within 2 hours, or it has been affected by lightning activity and may continue, so there is a great possibility of lightning disaster.

Defense guide:

1. The government and relevant departments shall implement lightning protection emergency measures according to their duties.

2. Arrange personnel to closely monitor the storage places of inflammable, explosive and dangerous chemicals, and the emergency professional disposal team is on standby at any time; Stop the transportation of the above items and properly dispose of them nearby.

3, stop outdoor production, tourism, sports, assembly, business and other activities; Don't swim outdoors or move near the water.

4. The amusement park immediately closes the outdoor facilities and transfers the tourists to a safe place; Workers working at heights such as roofs, scaffolding and tower cranes. Stop working immediately and move to a safe place.

5. Don't shelter from the rain under trees, tower cranes, transformers, isolation sheds and huts. Hide in buildings or cars with lightning protection facilities as soon as possible, and close the doors and windows.

6. Don't take an umbrella outdoors. When lightning strikes, don't carry farm tools, badminton rackets and golf clubs on your shoulders. Don't ride horses, bicycles, electric cars or motorcycles.

7, cut off the dangerous power supply, away from wires, transformers and other live equipment, away from towers, chimneys, telephone poles, flagpoles, antennas and other tall objects, away from lightning rods and their downlead of buildings, away from barbed wire, water pipes, metal doors and windows and other similar metal devices.

8. Drivers and passengers are not allowed to stick their limbs out of the car, and their feet should be off the ground or off the car at the same time when getting on and off.

9. If you are in an open place, when there is lightning and thunder, you should kneel down immediately, put your feet together, put your hands on your knees, and bend forward. Don't lie on the ground, in the ditch or in the pit.

10, the public should stay indoors, close doors and windows, do not use TV sets, stereos, computers and other electrical appliances, unplug the power supply, reduce the use of telephones and mobile phones, and do not take a shower.

(3) Lightning red warning signal

Standard: There is a great possibility of lightning activity within 2 hours, or strong lightning activity has occurred and may continue, and there is a great possibility of lightning disaster.

Defense guide:

In addition to doing a good job in defense according to the yellow warning signal of lightning, we must also do the following:

1. The government and relevant departments should do a good job in lightning protection emergency rescue according to their duties.

2. Personnel should stay indoors, close doors and windows, turn off TV, stereo, computer and other electrical appliances, unplug the power plug, try to avoid using telephones and mobile phones, and stop taking a shower.

Second, how to prevent electric shock accidents in thunderstorm season?

Old, aging or damaged wires should be replaced in time to prevent accidents such as hanging upside down and leakage, which may harm personal safety. When you use electricity abnormally, please stop using electrical appliances immediately, and check whether your switch safety and wiring are normal. If the outdoor line is found disconnected, you should keep a safe distance from the falling point and ask the power department for help in time.

3. Where is it easy to be struck by lightning?

Generally speaking, places with low soil resistivity and obvious changes in soil resistivity are prone to lightning strikes. Areas with metal deposits, river beds, underground outlets, hillsides bordering rice fields, hillsides and foothills, riverside, lakeside, seaside, low-lying areas and places with high groundwater level are all vulnerable to lightning strikes. Some isolated tall buildings (structures) such as iron towers and chimneys are also vulnerable to lightning strikes. When a thunderstorm comes, because the trees are taller, they are easily hit by lightning. Stay away from trees in thunderstorm weather, and try to squat down with your feet together.

4. What should I pay attention to when encountering strong lightning?

1. If you happen to be at home when there is strong lightning, it is recommended not to venture out. Don't use radios and televisions with external antennas, and don't answer the phone.

2. If you are in the wild, you should seek shelter immediately. Take concrete buildings with lightning rods, steel frames or steel plates as lightning protection places, and vehicles with complete metal compartments can also be used.

3. When there is no shelter, don't go near the open space, and don't go near the lonely tree on the top of the mountain, which is the most vulnerable place to be struck by lightning. Don't stay in open waters and boats; Try to avoid tall trees and forest edges, around wires and flagpoles, and near high objects without lightning protection equipment, such as haystacks and tents. Don't get close to huge metal objects such as railway tracks and long metal railings, and don't stay at the top of the mountain and commanding heights.

4. During the lightning, it is best not to ride horses, bicycles, electric cars or motorcycles; Don't carry metal objects in the open air; Do not go near any part of lightning protection equipment.

5. If you can't find a suitable lightning protection place, try to lower the center of gravity and reduce the contact area between the human body and the ground. You can squat down, put your feet together, put your hands on your knees, lean forward, and never lie on the ground, trenches or pits. If you can wear a raincoat, the lightning protection effect will be better. People in the wild, whether moving or static, should be separated by a few meters, not crowded together, or they can hide in bigger caves.

6. Note that when your hair stands on end or your skin vibrates, lightning strike may occur, so you should fall to the ground immediately. People who are struck by lightning may be burned or severely shocked, but they will not be charged and can be rescued safely.

7. Never use your mobile phone when it is thundering!

5. What is the secret of personal lightning protection?

1, stay indoors and close the doors and windows; People who work outdoors should hide in buildings.

2. TV, audio and other electrical appliances without lightning protection measures or insufficient lightning protection measures should not be used, and faucets should not be used.

3. Don't touch antennas, water pipes, barbed wire, metal doors and windows, external walls of buildings, and stay away from live equipment such as wires or other similar metal devices.

4. Reduce the use of telephones and mobile phones.

5. Don't swim or engage in other water sports. Outdoor ball games are not suitable. Leave the water and other open spaces and find a place to hide.

6, don't stand on the top of the mountain, the roof or other places close to highly conductive objects.

7. Don't handle flammable items in open containers.

8. When you can't hide in a building with lightning protection facilities in the wilderness, stay away from trees and masts.

9. It is not advisable to take an umbrella in an open place, and it is not advisable to carry badminton and golf clubs on your shoulders.

10, not suitable for driving a motorcycle or riding a bike.

Six, how to first aid after being struck by lightning?

1. The injured person lies flat and unbuttons his belt.

2. Immediately perform mouth-to-mouth resuscitation and chest compressions until the patient wakes up.

3. Hand-guided or acupoints such as Renzhong, Xuan Shi, Yongquan and Mingmen.

4. Send to the hospital for emergency treatment.

Seven, what are the measures to prevent electrical fire accidents?

1, the household power cord should be prevented from being overloaded, and the worn and aging power cord should be replaced in time to avoid accidents; The general insurance of household power supply and household insurance should be reasonably configured to protect household appliances.

2. When decorating the room, the power cord hidden in the wall should be placed in a special flame-retardant sheath, and the cross section of the power cord should meet the load requirements.

3, household electric heating equipment, heating equipment must be far away from the gas tank. When gas leakage is found in the gas pipeline, the window should be opened for ventilation first. If the power supply cannot be connected, professionals should be asked to repair it in time.

4. When using electric irons, soldering irons and other electric heating devices, be sure to stay away from flammable materials. After use, cut off the power supply and unplug the electrical appliance to prevent accidents.

5. In case of household appliances catching fire, cut off the power first and then put out the fire. Never use water directly to prevent electric shock.

Eight, why should we pay more attention to prevent electric shock accidents in summer? How to prevent it?

It is hot in summer, and household appliances are used frequently at this time. In high temperature season, people sweat a lot, and their hands often sweat. Sweat is conductive. Therefore, in summer, we should pay special attention to:

1. Don't move running household appliances by hand, such as desk fans, washing machines, televisions, etc. If it is necessary to move, turn off the switch and unplug it.

2. Don't repair live lines or equipment at home by hand. Please put on your shoes and gloves if you need live maintenance.

3. For electrical appliances that are often used in summer, such as electric shower, desk fan, washing machine, etc. Some practical measures should be taken to prevent electric shock, such as often testing whether the metal shell is charged with an electric pen and installing an electric shock protector (leakage switch).

4. If water enters the house unexpectedly, cut off the power supply first, that is, unplug the main switch or fuse in the house to prevent the household appliances being used from accidents due to water entry and insulation damage. Secondly, after cutting off the power supply, move the household appliances that may be wetted to a place that is not wetted, so as to prevent the insulation from being wetted, which will affect future use. If the electrical equipment has been soaked in water, a special shaking table should be used to test the insulation resistance of the equipment before reuse. If it meets the specified requirements, it can be used, otherwise it should be dried until the insulation is good.

9. What are the most basic common sense of preventing electric shock in bad weather?

1, strong winds, thunderstorms and other bad weather, you should try to reduce going out. If you have to go out and walk, observe the terrain carefully, walk carefully and avoid stepping on wires. Avoid walking around power facilities such as telephone poles and iron towers, and bypass fallen wires.

2. Don't walk barefoot.

3. indoors, in case of thunderstorm and windy weather, turn off the running household appliances in time and unplug the power supply; Don't go barefoot to repair live lines or equipment at home; If the home is accidentally flooded, the power supply should be cut off immediately to prevent the household appliances being used from accidents due to water ingress and insulation damage.

4. When walking outdoors in rainy days, pay attention to observation, and don't touch the metal parts of street lamp poles, signal lamp poles and landing billboards. Where there is water, we should go around.

5, found that the switchboard, box-type substation and other power facilities flooded, in their own and other personnel are not close at the same time, to promptly notify the power supply department for processing.
