When lightning strikes a building fire can be started and electrocute any person who is in the vicinity. So the question is how can people protect themselves against one of the strongest and random forces of nature? There is a simple device known as a rod or a finial which can guard all sorts of buildings against being destroyed during a storm. A lightning rod or a finial is a metal rod that is fitted on top of tall buildings or other structures such as bridges and ships that need protection from lightning.
These metallic rods do not have to be only straight, but they can come in all shapes such as pointed, rounded and flat. Depending on one’s choice, they can choose a finial that is either hollow, solid or one that resembles a brush. It does not matter what shape they come in, they all work in a similar manner to draw the electrical charges from a lightning strike and divert the energy by transferring it to the ground using a wire attached to the device.
The lightning rod depends on three elements to transfer the charges to the ground, the metal rod, the wire, and a ground absorber. When lightning hits the finial, through a conductive material, the electricity travels along the conductive wire directly to the ground. The ground also referred as the earth is another piece of metal that is directed to the real ground. Once the electricity charges are disposed of off well to the ground, that means that no damage is done to the structures being protected. However, if the homeowners suspect that the building was hit by lightning, they should inspect their house to ensure that the house is in order because a lot of energy was transferred.
Buildings that need more protection should use a system of networked devices and not just a single rod as that will not be enough to prevent damage from occurring. These conductors are then connected to the ground to send the electricity charges to the ground as quick as possible.
Deciding to spend your hard earned cash to put a finial in your building is a hard decision that every homeowner should consider. It is essential to know if your home insurance covers lightning protection as you will know how to proceed either alone or with the insurance company. If you know you reside in areas that are more vulnerable to thunderstorm it is a good idea to invest in a lightning rod as that is an investment you will not regret.
Although it is not common for lighting to strike small structures like homes, it is advisable to install a finial as it provides a peace of mind and adds an element of protection. This device has made people rest east during a storm and enjoy the magnificent display of nature without too much worry about lightning strikes.
