Was going to post this in the Adventure forum but I dont have access to it. :(

Recently took a class on the topic for college and thought I would share, you never know when it might save a life on the trail.

#1 thing to remember, if someone is struck they will hardly ever have a pulse. THEY WILL APPEAR CLINICALLY DEAD. This is caused my Vaso-spasms (repeated constriction/ dialation of blood vessels) induced by the shock to the autonomic nervous system. Also, the pupils will be fixed and non-responsive to light. Again, caused by the shock to the nervous system. This shock can last from 15-20 minutes after being struck. By then, the nervous system should have reset.

Anytime someone is struck they must be transported to a hospital and never declared dead on the scene. There is NO way to tell if they really are dead.

#2 Person struck will present stroke syptoms.

#3 Often there are injuries from blunt force trauma. Usually dislocations will present from the actual force of the strike. Most common is the posterior shoulder dislocation.

#4 If extreme swelling occurs ice effected area. Fasciotomy may be needed. Im not going to describe a Fasciotomy, google it.

Just trying to look out for some fellow jeepers in the event of an emergency. :)

Lighning can strike up to 10 miles. It has be known to strike as far as 16 miles from the storms center under clear skies. IE: Out-of-the-Blue strikes.

If you hear thunder on the trail just stay in your jeep. With your hands off of the metal frame/ cage.

Hands off the outside of the metal frame, the charge will travel along the outside surface of the metal.
 
^Yes sir, many people think that the rubber grounds the car. It doesn't. The plastic interior allows the current to pass around you into the ground.

The best place to be if caught in teh open is sitting indian style. NOT UNDER A TREE. The current will jump of the tree into your body or from the charged ground around the base of the tree into your body. In an effect called Splashing.
 
Indian style is incorrect, though is better than standing/laying down. You want to crouch down, like a baseball catcher with the balls of your feet together contacting the ground. Hands on your knees. Head ducked. ;-)

Ya thats right, I didn't see that before. Crouching with your head tucked in is the way to do it.
 
While you guys are technically 100% correct, have you tried to stay in that position for a long amount of time? lol

I was taught by a trauma attending that Indian style is just as good. The goal is to not have a situation where the current can travel up one leg, through your trunk, and out the other leg into the ground.

Does that make sense? lol
 
I'm a little hardcore into meteorology lol, and being a firefighter for 7 years, EMS attendant for 4, etc. 50% of our house fires in summer were started from lightning. Winter was mainly space heaters and candles. /offtopic

It all works though as has been discussed :)

I thought it was kinda funny that the odds of being struck in the US are 1/700,000. But then in Fla. the odds are 1/5,000.

While PA has the highest amount of lightning strike insurance claims out of the country.
 
I love this state :)
