Types of Lightning Protection:

Berkley Lightning Rods

  • The Berkley Lightning Rods are used on boats and withstands lightning strikes in saltwater and freshwater. Made from graphite material and coated with titanium, these light rods cost $39 at Bass Pro Shops

Weather Vanes

  • Weather vanes made of copper look like animals such as horses and roosters on top of directions. People install them on top of residential structures and barns

Surge Arrestors

  • Individuals interested in surge arrestors install these types of lightning protection devices if they want added safety. A surge arrestor kit includes an arrestor and grounding wire. An outdoor arrestor kit works with wireless devices and outdoor cables and underground wires.

Ditek Total Surge Solutions DTK-6GTP

  • This form of lightning protection includes six outlets, a retention screw and a ground termination point. The wall mount can protect up to six electrical devices

Lightning Protection Methods:

Lightning Rods

  • 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

Surge Protectors/Unplugging

  • 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

Personal Lightning Protection:

  • 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
