  • Causes more U.S. deaths than tornadoes
    hurricanes combined
  • The 1 weather killer in Florida
  • Annual U.S. Strikes Kill 100 and Injure 1,000
  • Causes 5 billion/year in economic damage

  • The 1 location of reported lightning deaths is
    on open fields, which includes athletic fields.
  • The 3 location for lightning deaths is water
    related, which includes swimming pools.

Possible Resistance when Promoting Lightning
Safety
Some may say Lightning is not an important
hazard. FALSE! Truth It is second only to
floods as the leading cause of weather related
deaths in the U.S. Safety plans are developed
for tornadoes and hurricanes, but lightning is a
more common and deadly hazard in the U.S. There
is nothing you can do about lightning.
FALSE! Truth Almost all lightning casualties
are preventable. If thunder is heard, go indoors
immediately. Most deaths occur before and after
a storm. Litigation Fear It is better to do
nothing, than to do something and fail. Truth
Failure to take prudent and protective actions is
chargeable negligence which could warrant a law
suit.

Electrical Current
  • When the negative charge in the cloud becomes
    great enough, it seeks an easy path to the
    positively charged ground below.
  • The current looks for a good conductor of
    electricity, or a tall structure anchored to the
    ground (such as a tree or a tall building). The
    negative charge sends out a feeler, called a
    stepped leader, which is a series of invisible
    steps of negative charges.
  • As the stepped leader nears the ground, a
    positive streamer reaches up for it. Only then,
    once this channel is made, does the visible
    lightning happen. A return stroke runs from the
    ground to the clouds in a spectacular flash.

Electrical Current Disperses
  • Electrical current from a strike will travel
    through the ground and other conductive mediums.
  • Wet fields will conduct electrical current from
    a strike.
  • The charge will electrocute life within its
    path.

Lightning Can Be Hot Enough To Fuse Sand Into
Glass Called Fulgurite
Imagine What It Can Do To Your Body!!!
10
When Thunder RoarsGo Indoors! The Flash-to-Bang
Method
  • Thunder is a sound wave created by a shock wave
    produced by the hot bolt.
  • Flash-to-Bang Count the number of seconds
    between seeing the lightning and hearing the
    thunder then divide by 5.
  • The quotient is approximately how far the
    storm is from you (in miles).

If you hear thunder, you are at risk of being
struck by lightning!
The sound of thunder travels 1 mi in 5 sec
11
Bolt from the Blue
Lightning can emanate from the upper level cloud
of the storm and strike the ground well away from
where it is raining, even where there are no
clouds.

Ground strikes are recorded up to 60 miles away
from the clouds that produce them (rare).

Heat Lightning
  • Heat lightning is lightning from a distant
    thunderstorm.
  • Thunder is not heard.
  • Not an immediate threat of lightning striking
    your immediate area, but be aware of the
    direction the storm is traveling.

14
Strikes to Humans
  • 84 of victims are male
  • Months of most instances Jun 21, Jul 30, Aug
    22
  • Time of Day of most instances 2-6 pm
  • 20 of victims are struck dead the other 80
    often suffer life-long debilitating neurological
    problems
  • Lightning strikes are not the same as electrical
    shocks the strike burns body tissue from the
    entry point (typically the head) through the exit
    point.
  • Strike survivors may chronically experience all
    or some of the following coma, seizures, brain
    damage, cardiac dysfunction, deafness, severe
    ocular damage, amnesia, sleep disorders, anxiety
    disorders, chronic pain.

Victims Do Not Carry Electrical Charge!
Administer CPR as soon as possible!
15
Some Concerns to Address with a
Lightning Safety Action Plan
  • How will you communicate lightning alerts to a
    large and/or noisy crowd?
  • Will the audience know how to react and where to
    go when they hear the lightning alert?
  • Where will everyone (athletes, officials,
    coaching staff, spectators, etc.) go at large
    outdoor events?
  • Will there be adequate safe shelter for everyone?

16
Outdoor Events Lightning A Deadly Combo
  • Outdoor events like athletic games put everyone
    near and on the field at risk of being struck by
    lightning.
  • Many stadium facilities have metal bleachers and
    long metal fences which may be excellent
    conductors of an electric charge.
  • Wet fields will conduct an electrical strike.

Official Safety Recommendation The 30-30 Rule
  • Use the 30-30 Rule to determine if lightning
    is a threat.
  • The 30-30 Rule If the number of seconds
    between seeing the lightning flash and hearing
    thunder is 30 seconds or less, then seek shelter
    immediately. Your lightning safety plan should
    be executed and those vulnerable to a strike
    should be evacuated to safety.
  • If you cannot see the lightning but hear
    thunder, then you are close enough to be struck
    by lightning. Execute your lightning safety plan
    immediately.
  • Wait at least 30 minutes after the last rumble
    of thunder before leaving the shelter area.

The 30-30 Rules is not too conservative. Most
lightning strikes to humans occur before and
after the storm.

Shelter Areas
Seek Proper Shelter
  • No place outside near a storm is safe from
    lightning.
  • Buildings are much safer than vehicles.
  • Vehicles offer some safety.
  • If caught outside in a storm, the last resort is
    to get low to the ground.

19
Unsafe Shelter Areas
  • All outdoor metal objects like flag poles,
    fences, gates, mast light poles, metal bleachers,
    picnic shelters, dug outs machinery.
  • Avoid trees, water, open fields, high ground.

Safe Shelter Areas
  • Substantial Buildings (a lot of wiring and
    plumbing) away from windows, plugged-in
    appliances and out of bathrooms and kitchens.
  • The low ground. Seek cover in areas of bushes
    (not under trees).

21
Indoor Lightning Safety
  • Avoid conducting paths to the outside, which
    include the following
  • Do not use corded telephones
  • Do not use wired electrical appliances
  • TVs, VCRs, And TV Cables
  • Computers
  • Light Switches
  • Electrical Outlets
  • Do not use plumbing
  • Showers
  • Sinks
  • Rest Rooms
  • Pools (indoors too)
  • Stay away from windows and doors
  • Interior rooms are safer

22
First Aid for Strike Victims
  • Lightning Strike Victims DO NOT carry
    electrical current after they are struck! You
    will not be shocked nor electrocuted if you touch
    them.
  • 90 of strike victims will survive. Fatal
    strikes cause cardiac arrest, thus the sooner CPR
    can be performed on the victim the better chance
    for their survival.
  • Ensure your own safety first before you attempt
    to help the victim. Make sure that there are no
    live wires.
  • Call 911 and administer CPR immediately.

23
Lightning Alerts
  • The National Weather Service (NWS) does NOT
    issue Severe Thunderstorm Warnings for Lightning
    (only for large hail and damaging winds)
  • Florida NWS offices monitor lightning frequency
    in storms and will issue a Special Weather
    Statement for storms that produce excessive
    lightning. You will hear this statement on NOAA
    Wx Radio or can read it on the internet.
  • Lightning Detectors can serve as a secondary
    means of alerting you to the possibility of
    lightning. The first method should be visually
    scanning the sky and monitoring the forecast.
  • There are some lightning notification services
    available for a fee. These services use the
    National Lightning Detection Network and will
    send you an email, page or fax to alarm you when
    lightning has been detected near your location.

24
Lightning Safety Plan Recommendations
  • Designate a responsible person as the weather
    safety lookout. This person will monitor the
    weather.
  • We suggest access to a NOAA Weather Radio and/or
    access to the Weather Channel.
  • 30-30 Rule When thunder and/or lightning are
    first observed, use the Flash-to-Bang method to
    determine about how far away the storm is from
    you. A Flash-to-Bang count of 30 seconds would
    approximate the distance of the storm as being 6
    miles away, and it is recommended to evacuate the
    outdoor facility immediately when this criteria
    is met. Spectators should be evacuated to safe,
    indoor shelter.
  • Outdoor activities should be suspended until 30
    minutes after the last rumble of thunder is
    heard.
  • Promote Lightning Safety Education!

If you can see it, flee it.
If you can hear it, clear it.
