With the summer coming
With heat and heat and hot sun
There's always lightning and storm
Speaking of thunder
Many security tips
We all know each other
But there are still thunderstorms
I really hope you're all right
Keep that little mine-proof knowledge down there
We'll kill security in the cradle
I need you to keep an eye on the area
Inside, there's no need to hide
Many believe that thunderstorms are temporary and safe as long as they stay indoors, and do not need to be used to avoid mines. The idea is wrong。
Even indoors, when mine-proofing is not observed, they are more likely to be hit by indirect lightning than by a direct lightning strike。
Thunder and rain
We can use solar water heaters
Solar water heaters are often installed on roofs for heating needs. Therefore, solar water heaters are usually located at altitudes above the building's mine-protective devices, i. E., solar water heaters are completely exposed to direct lightning。
In addition, electric heating power lines and sensor signal lines inside the solar water heater are connected to the interior, and there are more metal components, making the water heater a “blazer”。
Once the building has been hit by lightning, water heaters bear the brunt. Some of the lightning currents will also enter the room directly through the water heater pipeline, power lines and signal lines, while light will result in the burning of water heaters and household appliances and heavy explosions, fires or casualties。
Shorter than taller
Some believe that buildings are easily targeted by lightning and are safe if their buildings are shorter. The idea is also wrong。
If the short buildings were adjacent to the high buildings and the mine-protected facilities were inadequate, the likelihood of being struck would not be diminished, but rather would increase significantly。
As long as there's a lightning rod
It's 100% mine
In fact, mine protection is divided into internal and external parts, and mine-proofing needles are only an important external mine-proofing measure。
The so-called lightning rod (the more precise name for which is “blitz pole” according to our national standards, according to the mine design code for buildings) is “direction” of lightning, which follows the line designed by the people to reach the flasher and is eventually safely introduced into the land from the ground. There were, however, instances of lightning going around a lightning rod and hitting buildings。
In addition, lightning rods can only protect against direct fire, but cannot handle sensory mines. Sensors are caused by powerful magnetic fields that cause rapid changes in the surrounding space by massive shock currents during discharge. It can be transmitted along circuits or through space electromagnetic fields, while electron and electrical equipment can generate sparks, fires, explosions or electrical accidents。
Defensive sensors, which require internal mine-proofing measures, i. E. Electromagnetic shielding, level connection, installation of electric surge protection, rational wiring, etc。
While some buildings are equipped with external mine-protective facilities, such as lightning rods, they are less protective of sensor mines. Mine-protective effects of 100 per cent cannot be achieved by relying solely on lightning rods。
I need you to remember that
Indoor mine protection points
01
Check the wires in time
Before the thunderstorm, check whether the household wire is ageing, the zero line or the ground line is broken, and the electrical shield is leaking. If problems are identified, specialized maintenance staff are required for maintenance or replacement。
02
Close the doors and windows and turn off the electrical appliances
In thunderstorm days, it is advisable to close doors and windows, shut down all electrical appliances in the home and remove power, network, etc. Plugs, preferably without wired telephones。
03
Don't go near the naked metal
Do not approach, or even touch, bare metal in the house, such as piped pipes, gas pipelines, heating tablets, etc., do not approach humid walls, and stay away from the fuses of lightning rods。
04
Better not shower
As you know, water can conduct electricity. Thunderstorms bathe in the weather and when lightning hits a building, it is able to pass through a pipe (e. G. Metal landing pipes and wire lines) and anyone who is in contact with a tap or associated device is electrocuted。
Outdoor mine safety points
01
Stay away from trees, billboards, etc
When in the open field it is not possible to hide in a building with a mine-protected device, it should be far away from high and isolated objects such as trees, utility poles and chimneys。
It is not appropriate to stay near bars, metal tan lines, empty metal bodies and railway tracks。
It is not appropriate to access small, small buildings such as isolated shelters and kiosks without mine-protected devices, far from power lines, empty telephone cables, etc。
Avoid as much as possible small areas that are particularly vulnerable to lightning, such as rock faults, larger rock mass cracks, ground exits of buried pipes, etc。
02
It's not for riding
In thunderstorm weather, if you are outside, do not allow your body to be taller than the rest of the surroundings and not to run on bicycles or motorcycles. The vehicle is a relatively safe place to avoid mines, but care is taken to secure the windows and the vehicle is parked away from water accumulation and from objects that are easy to conduct, such as electrical installations or billboards outside the house。
03
No water activity
If you are swimming outside the house, you have to get out of the water and avoid being struck by lightning。
It is not advisable to stay in swimming pools, lakes, water fields and small boats. It is not appropriate to conduct boating, fishing, etc。
04
We'll bypass the water
(b) try to bypass the water catchment and, if it does not, first look around and see if there are wires falling in the water. If a high-pressure line in the vicinity is observed to be broken by lightning, vigilance is maintained, as there is a multi-step voltage near the power outage of the high-pressure line。
05
Check the wires in time
If there is no suitable shelter for mines and lightning has come to the top of the head, stay low, keep your feet together, keep your back flat and your head low, and quickly remove the metal from your body (eyes for metal frames, metal accessories, etc.) and place it a few metres away。
