FACTS & FALSEHOODS ABOUT LIGHTNING
Mother Nature offers many wonders that are a spectacle to behold. Ranking among
some
of the more awe-inspiring is lightning. Every year lightning strikes the earth
roughly 25 million times a
year and causes $4-$5 billion in the U.S.

While lightning is certainly a beautiful vision illuminating the sky, its immense power
can
have a downside, including the potential for destruction and even death.
Lightning is five
times as hot as the sun in every one-inch diameter bolt. In the U.S.,
lightning kills more
people than hurricanes and tornadoes, combined. Only floods are
more deadly. According
to Underwriters Laboratories, lightning also accounts for more
than one billion dollars
annually in structural damage to buildings in the U.S.

Considering lightning inspires awe and wonder, and also some fear… it is beneficial
to
separate fact from fiction when it comes to lightning safety.

1. People are poor lightning conductors.
Fiction.
The human body is a better conductor than insulating building materials,
water, and many metallic systems. The body is over 90 percent fluid, which is why
sticking a finger in an electric socket or even experiencing static electricity when
touching a doorknob can shock you.

2. If you are caught outdoors, it can be safe to seek shelter
    from lightning in a car.

Fact.
A vehicle that is fully-enclosed with metal can provide better protection
against lightning than standing outdoors in a storm.
 

3. Lightning rods attract lightning.
Fiction. A lightning protection system simply intercepts a lightning strike and
provides a safe path to ground for discharging the dangerous electricity.

 

4. Surge arresters, suppressors and “whole-house protectors”
    can protect my home.

Fiction. Surge protection devices are important components of a complete system
to protect incoming utility lines against infiltration, but can do nothing to protect a
structure against direct lightning strikes. Surge protection must be installed in
conjunction with a structural lightning rod system (air terminals, bonding and grounding)
to provide whole house protection.

 

5. Insurance covers all damages caused by lightning.
Fact & Fiction. While this is generally true for an initial occurrence with lightning,
many insurance companies will deny second or third lightning claims and many will
not renew a policy after a lightning claim is entered.

 

Since a single bolt of lightning can carry over 100 million volts of electricity (enough
power to rip through a roof, explode walls of brick and concrete and ignite fires),
homeowners may want to consider the security and peace of mind that a lightning
protection system offers. A professionally installed lightning protection system
provides a safe path to channel lightning’s electrical energy into the earth.
The Lightning Protection Institute (LPI), a not-for-profit nationwide group founded
in 1955 to promote lightning safety, awareness and education, stresses that
homeowners should only use experienced contractors to install protection systems.
LPI states that the contractor should be reputable, use UL-listed materials and be
LPI-certified in lightning protection.

 

“It is important to have an experienced professional install the lightning protection
system,” says Bud VanSickle, executive director for LPI. “Contacting a certified
professional ensures safety and expertise to save consumers time and money.”

 

The Lightning Protection Institute offers a list of certified contractors, along with
information regarding the national safety standards for lightning protection installation.
