Summer is a season of high lightning, like riding outdoor riders, it will inevitably encounter thunderstorms, such as riding in the way of thunder and lightning, should have a sense of security, strengthen prevention, as soon as possible to find lightning, to ensure that their own ride Friends personal safety.
First, do not make yourself cutting-edge, that is, try to reduce your height. You should not place objects with metal on your shoulders above your head because it will increase the chance of direct lightning strikes.
Second, it is necessary to minimize the contact surface between the human body and the ground in order to reduce the step voltage damage. The best way is to find a valley or a depression. When you have to, you can use your feet together on the flat ground to get down and down, which will reduce the height and prevent the step voltage.
Third, in a dense forest, it is best to find a piece of hollow forest, choose the place near the trees, feet close together. At this time, as the tall trees are easily struck by lightning, the lightning protectors in open areas are protected. It is extremely unsafe to hide thunderstorms under big trees, because such tall and large objects are vulnerable to lightning strikes. Lightning strikes produce side flashovers, contact voltages, and step voltages, and severe cases can cause death.
Fourth, riding in the mountains, such as the road to the cave can also enter the lightning. Stand in the hole and close your feet. No part of your body can touch the wall or the top of the hole. Because the cave is part of the surface, once the lightning strikes, the contact voltage and the step voltage can be fatal.
5. During thunder and lightning, keep away from tall objects and metal objects (such as fences, railroad tracks, etc.); it is best not to go to lakes, rivers and seas for fishing and boating, and do not go swimming because these electrical conductors are easy to attract lightning. Also do not approach or touch any part of lightning protection equipment to prevent side flashover, contact voltage and step voltage. In a flat open area, it is best not to ride a bike, because at this time you may become a prominent object in the surrounding environment and attract lightning strikes.
6. If you are at the top of the mountain, you must quickly leave the highest point. If you are in an empty place and you find a suitable place for lightning protection quickly, you should quickly squat down on the ground and strive to keep the dry insulation under your feet. Raincoats and plastic sheets can be used. If conditions do not allow it, you can kneel down, hold your two limbs together, hold your knees in both hands, and put your head on your knees to reduce your height and reduce the contact area with the ground. Insulate your feet (such as plastic sheeting, rubber items, etc.). When people are more, they should be dispersed and should not be squeezed together.
Seventh, to avoid the terrain easily lead to lightning, such as tall trees, under the telephone poles, the edge of the forest, the house down, the top of the mountain, open water, vast fields and so on. If you swim in the water, you must go ashore quickly, dry your body, and seek shelter.
8. During the thunder and lightning period, it is necessary to promptly close the mobile phones they carry in the wild and wireless walkie-talkies to ensure safety. Activities should be stopped to find nearby places for lightning protection, such as caves and filmed houses. Indoors are generally safer.
Lightning weather tents prevent lightning attacks
1. Are aluminum rods as good conductors that attract more lightning than glass rods?
The choice of lightning is based first on the height of the conductor, which hits the highest among several conductors. In addition, because thunder and lightning are usually in the rain, regardless of the glass rod or the aluminum rod, the fabric of the tent becomes a conductor due to wet water. Therefore, the attraction of thunder and lightning is more determined by the height rather than the pole.
Second, how to prevent the tent from being struck by lightning?
The damage from lightning mainly comes from two aspects: 1 is direct radon, 2 is high voltage arc. To avoid direct criticism, the simple principle is not to become the highest point in this region, and it is most likely to be distracted. The arc is the phenomenon of air discharge caused by the high voltage of lightning. After hitting an object, an instant high voltage will form an arc near the object and cause damage. Therefore, while not becoming a high point, it is also necessary to avoid camping next to the high point, or else it will be struck by an arc. Therefore, the ideal way is to choose a place where the overall topography and vegetation height are relatively low, and which can be kept away from tall plants or buildings.
Third, if it is hit, aluminum rod and glass rod which is better?
In theory, the glass rod cannot be used to share the current through the body because it is not conductive, while the aluminum rod can act as a parallel conductor to help the body to carry part of the current.
There have been cases in history where people who were struck by lightning survived because the clothes were all wet and conductive. Therefore, the wetter the tent is, the more conductive the pole is, and the less harmful it is after being hit. However, this can not avoid the huge damage caused by the high voltage arc, so once it is hit, it is extremely dangerous. In the area of ​​lightning strikes, it can be divided into two situations:
Which one of the glass rods and aluminum rods leads to lightning. If you ignore the actual use, aluminum rods do indeed lead to lightning. But in fact, because the rain tent has become a conductor throughout the day and the poles are not normally exposed outside the tent, this difference is not significant. Of course, the sunny tent or a large number of metal poles outside the tent is not considered.
If struck, glass and aluminum rods are more likely to avoid hazards.
all in all:
A. We discussed that lightning strikes the tent instead of hitting the human body directly. There is no direct contact between the aluminum rod and the human body. Therefore, this situation is totally different from the fishing rod.
B. The lightning hitting the tent is not directly hitting the human body. What should be avoided at this time is not the electric current directly through the human body but the arc and the high temperature. Therefore, the role of the principle similar to rubber shoes is not suitable in this situation.
C. The huge energy of lightning must inevitably need to be transformed. It is possible that this process may occur through conductors entering the ground, generating arcs, and generating high temperatures.
In any case, choosing the right camp to avoid lightning strikes is the right way. The aluminum pole tents are theoretically safer choices.
When the thunder and lightning is very strong and there is no suitable terrain, even the trekking poles or tent poles can be pulled up to the longest, inserted in the ground about 10 meters away from the tent, and they curled up in tents without poles.
So riders should master:
1. If it is raining in the rain, the aluminum rod is no more dangerous than the glass rod, and it may be safer. Because no matter what pole tent will become a conductor at this time, it is important to focus on who can better digest the current after a lightning strike.
2. If it is sunny and thundering, the aluminum rod is more dangerous. Because only aluminum rod tents attract lightning strikes at this time.
3. Selecting the account pole is only secondary lightning protection measures. What really matters is to grasp the basic principles of camp selection and prevent lightning prevention.
4, tents do not constitute a thunder and lightning! Because the top of the tent is almost a curved object rather than a "very" sharp object. So don't attach any equipment to the tent, such as tying a flag, hand antenna, etc.
