Lightning Safety
- All thunderstorms produce lightning and are
dangerous.
Lightning kills more people each year than tornadoes.
- Lightning often strikes as far as 10 miles away
from any rainfall. Many deaths from lightning occur ahead of the storm because people
try and wait to the last minute before seeking shelter.
- You are in danger from lightning if you can hear
thunder. If
you can hear thunder, lightning is close enough that it could strike your
location at any moment.
- Lightning injuries can lead to permanent
disabilities or death. On average, 20% of strike victims die; 70% of survivors suffer
serious long term effects.
- Look for dark cloud bases and increasing wind. Every flash of lightning is
dangerous, even the first. Head to safety before that first flash. If you
hear thunder, head to safety!
- Blue Skies and Lightning. Lightning can travel sideways
for up to 10 miles. It may also be associated with a discharge between the
ground and the anvil cirrus, as opposed to the main body of the cumulonimbus
cloud. So if you hear thunder, even if the sky looks relatively clear, it's
best to be cautious and take cover. At least 10% of lightning strikes occur
some distance away from the parent thunderstorm.
Lightning Safety Tips for Inside the Home
- Avoid contact with corded phones.
- Avoid contact with electrical equipment or cords. If
you plan to unplug any electronic equipment, do so well before the storm
arrives.
- Avoid contact with plumbing. Do not wash your hands, do
not take a shower, do not wash dishes, and do not do laundry.
- Stay away from windows and doors, and stay off porches.
- Do not lie on concrete floors and do not lean against
concrete walls.
Lightning Safety Tips when caught Outside
·
Postpone activities promptly.
Don't wait for rain. Many people take shelter from the rain, but most people
struck by lightning are not in the rain! Go quickly inside a completely enclosed
building, not a carport, open garage or covered patio. If no enclosed building
is convenient, get inside a hard-topped, all-metal vehicle. A cave is a good
option outside but move as far as possible from the cave entrance.
·
Be the lowest point. Lightning
hits the tallest object. In the mountains, if you are above treeline,
you ARE the highest object around. Quickly get below treeline and get into
a grove of small trees. Don't be the second tallest object during a lightning
storm! Crouch down if you are in an exposed area.
·
Keep
an eye on the sky.
Look for darkening skies, flashes of lightning, or increasing wind, which may
be signs of an approaching thunderstorm.
·
Listen
for the sound of thunder. If you can hear thunder, go to a safe shelter immediately.
·
If
you see or hear a thunderstorm coming or your hair stands on end, immediately
suspend your game or practice and instruct everyone to go inside a sturdy
building or car. Sturdy
buildings are the safest place to be. Avoid sheds, picnic shelters, baseball
dugouts, and bleachers. If no sturdy building is nearby, a hard-top vehicle
with windows closed will offer some protection. The steel frame of the vehicle
provides some protection if you are not touching metal.
·
Listen
to NOAA Weather Radio.
Coaches and other leaders should listen for a tone-alert feature during
practice sessions and games.
·
If
you can't get to a shelter, stay away from trees. If there is no shelter, crouch in the
open, keeping twice as far away from a tree as it is tall.
·
Avoid
leaning against vehicles. Get off bicycles and motorcycles.
·
Get out of the water. It's
a great conductor of electricity. Stay off the beach and out of small
boats or canoes. If caught in a boat, crouch down in the center of the boat
away from metal hardware. Swimming, wading, snorkling and scuba diving are
NOT safe. Lightning can strike the water and travel some distance beneath
and away from its point of contact. Don't stand in puddles of water, even
if wearing rubber boots.
·
Avoid
metal! Drop metal
backpacks, stay away from clothes lines, fences, exposed sheds and electrically
conductive elevated objects. Don't hold on to metal items such golf clubs,
fishing rods, tennis rackets or tools. Large metal objects can conduct lightning.
Small metal objects can cause burns.
Move away
from a group of people. Stay several yards away from other people. Don't share a bleacher bench
or huddle in a group.
