Lightning is caused when atmospheric pressure separates positive and negative electrical charges. When the charges are very large, a giant spark results, or the electricity races to the ground. According to the National Lighting Safety Institute, a bolt of lightning can heat the air to 54,000 degrees Fahrenheit. Because of the force of the lightning and because of the potential damage it can do, it is essential to learn how to protect yourself from lightning. - Lightning rods are mounted on the tops of houses. Because the rod is taller than the house itself, it attracts the lightning to it. Cables connected to the lightning rod lead the electricity to the ground, where it is safely dispelled in buried ground rods. Although lightning rods were highly effective in premodern housing, the addition of conductive materials such as metal piping, telephone wiring and metal wall studs can still channel the electricity of nearby lightning strikes into the home. While lightning rods do protect from a direct strike, it is important have an electrician ground your home as well due to the other conductive materials in the structure.
- If lightning strikes nearby power lines or the house itself, it can follow the wiring or the phone lines into the home. The energy from the surge may damage the electronics in your home. To prevent this damage, connect all electrical appliances to a surge protector, which helps dispel the electricity safely before it gets to the electronics. In cases of very strong strikes, however, the electricity can jump through the surge protector and still strike home appliances. To prevent this from happening, unplug all appliances during a lightning storm. Ideally, unplug the appliances before the storm begins, as touching appliances that are plugged in during a storm can lead to a strong shock if the surge strikes just as you are touching the appliance.
- It is important to know what to do if you are caught in a lightning storm. If you are caught outside, avoid water, high ground and all-metal objects. Take refuge if possible in a substantial building or in a fully enclosed hard-top car. If you are caught in the open, crouch down and put your feet together while placing your hands over your ears. If you are indoors, avoid water and stay away from windows and doors. Avoid using the telephone, take off any head sets and stay away from your appliances. According to the National Lightning Safety Institute, remain watchful for 30 minutes after the storm has passed.
