Updrafts agitate the smaller positively charged particles upward and gravity pulls the bigger negatively charged particles downward. This results in clouds having their upper part positive charges and lower part negative charges (Adekoya & Nolte, pp. 45-50). This partition of charges causes a large electric capableness not only between clouds themselves but also between the clouds and the earth. This electrical potential sometimes contains order of magnitude of million voltages. Ultimately, the electrical battle in the air collapse and lightning, the electrical expulsion between the areas of the cloud or between the cloud and the earth, takes place (Adekoya & Nolte, pp. 45-50). A lightning strike can cause death several(prenominal) injuries to human beings. The method of deformity is distinctive, and the demonstration differs from those of other electrical injuries.

Firstly, people should stay at safe places during thunderstorm. However there are no entirely safe places, but some places are safer than others are (Renner, pp. 23-39). Large and envelop structures are considered as more appropriate to stay at than smaller and clear(p) structures. The danger for lightning injury depends on the structure having a feature of lightning protection, materials used in its construction and size of the structure. Generally, completely enfol d metal automobiles such as trucks, cars, vans, etc (Adekoya & Nolte, pp. 45-50), with the windows turned up give good protection from lightning. One should reduce touching metal or conducting surfaces inside or the vehicle. Secondly, one should avoid going to high and open places, remote trees, defenseless gazebos, picnic points, baseball bunkers, connections towers, flagstaff, light pole, metal and wood benches, farm carts, and water related places such as oceans, seas, swimming pools, and rivers. One should stay away from using telephone, taking bathe, washing give and dishes. Moreover, one may avoid contact with metal doors and windows, wiring cables of telephone, and television. If individuals can observe lightning and hear to-do of thunder, they are already at threat. Noisy or repeated thunder shows that lightning activity is imminent and it is change magnitude
