In recent years, the climate in our latitudes has changed markedly, with that statement, no one argues. Tornados, rainstorms, hurricanes, thunderstorms, more similar to tropical than familiar to us, more or less safe ... Every year statistics are increasingly numbers of fires caused by lightning, the dead or injured people during thunderstorms, although a couple of decades ago, the death people in a thunderstorm in our area was a rarity. Most often, the lightning strikes a person in public places, slightly less - in a room and even less - in the woods under the trees. How could protect themselves during a lightning storm from the danger?
Science can not understand it well with the nature of lightning. Whatever the year, new surprises. Even the installation of a lightning rod does not guarantee full protection of the building out of trouble. From direct lightning strike lightning protection, but from the so-called secondary manifestations - no. The fact is that when lightning strikes the ground or any object within a radius of 1500 meters from the building is likely to move towards him electric shocks on various communications that can carry current: power systems, communications, gas pipeline. This causes a sharp increase in voltage in electrical networks, leading to a variety of emergency situations - from the burning chips in appliances to the complete failure of electrical equipment.
Specialists from the MOE recommended by a storm off in the house all the electrical appliances and not use a regular phone, not to stand at the windows and doors, do not touch the taps. So you will save from unexpected problems and his technique, and their health. Make sure that the room had no draft, which can attract a fireball. Stove or fireplace is better not to drown in the time since coming out of pipe smoke has a high electrical conductivity, and the probability of a lightning strike into the pipe increases.
Being on the street in the park or forest can not hide under tall trees, it is better to leave them at 30-40 meters. The probability of lightning strike at a particular tree is directly proportional to its height. Especially, as they say, "attract the lightning" poplar, oak, pine and spruce. Birch, maple, walnut practically not subjected to a lightning strike. The danger increases if nearby trees have been previously struck by lightning. In the city try to escape as soon as possible in a store or apartment building, they have a reliable lightning protection, as opposed to public transport. If these options do not need to wait out the storm, crouching under low plantings. Cell phone while in the street is better off.
Oddly enough, experts advise not to disclose on an umbrella! Probably because of it many metal parts. It is also quite dangerous to stand near the wall, near which grows tall tree, it is better to stay away from electrical wires, antennas and just humid walls. Not recommended to stay at higher elevations and in open unprotected areas. Especially if located near metal or mesh fences, power lines, large metal structures.
But the car is a safe haven during a storm and it is better not to leave. Need to close the window and drop the car antenna, stop moving and wait out the weather on the roadside or in the parking lot, sitting away from tall trees. Bicycle and motorcycle, on the contrary, are at this time potentially dangerous. They need to keep away, having laid on the ground and left them on the storm at a distance not less than 30 meters. Even more dangerous to be in a tractor in an open field!
Lovers of swimming and fishing with the approach recommended threaten not only immediate cessation of these activities, but go away from the pond. Do not try to seek shelter in the flood plain bushes! If around the open field, you need as soon as possible (but not running, if the storm had already begun) to get to the nearest forest (not a handful of trees in open areas) or to the village. In this case, try to walk away, two hundred yards, standing trees and other tall items.
Separately to say about the fireball, which in general is a mystery? You never know what to expect from it. Therefore, when meeting with her to stay calm and stop the slightest movement, so that the resulting air flow will pull her along, and in contact with something it explodes.
Finally, a word about how to learn to expect thunderstorms approach. To determine how far away it is, or zoom, you need to measure the time between the flash of lightning and then thunder. It is known that the velocity of sound in air is about 344 m / s, ie for 3 seconds, the sound is about 1 km. If the time from the flash of lightning before the thunder is gradually decreasing, it means that a thunderstorm is approaching you. On this basis, we can calculate the approximate distance to the epicenter of storm and take measures to ensure its security. The most dangerous situation when immediately after the flash of lightning rumbling thunder - means storm cloud is right above you.
