Attend to any external burns or injuries if the victim is breathing and has a pulse. Keep the victim as calm and comfortable as possible. Remove any wet clothes, if possible, and cover the victim with clean, dry coverings. Avoid objects and places that are more likely to be struck by lightning if you are caught in a thunderstorm. If you're in the water and a thunderstorm occurs, get out immediately.
Water is an excellent conductor of electricity.
If you're in your car, stay there. Stay in that position until the threat has passed. Contrary to popular belief, it IS possible to be struck by lightning more than once. Although most people will never be struck by lightning, there are documented cases of unfortunate individuals who have been struck by lightning 2 or more times. Men are four times more likely to be struck by lightning than women are.
