The average bolt of lightning carries over 100,000,000 volts and can reach out over 100 miles. It is estimated that the odds of being struck by lightning over your lifetime is 1 in 3,000. 

There are many ways a strike can result in an injury.  A direct strike, usually results in cardiac arrest and/or stoppage of breathing.  A side flash may occur when the body of a person provides an alternate or parallel path for the current.  Conducted current from a lightning flash may range from a tingling shock to a massive current diverted from a poorly grounded electric power pole through the wiring system. Step voltage radiates out through the ground from a struck tree or pole. Fires and fallen trees from lightning strikes can also cause injury.

Rubber-soled shoes provide absolutely no protection from lightning.  If you can hear thunder, you are within 10 miles of a storm and are within reach of lightning.  An automobile can offer protection by acting like a Faraday cage, provided that the occupants do not touch the metal of the car while inside. There are several things one can do if caught outdoors when a lightning storm strikes. Take shelter inside a building or car (do not touch any of the metal of the car while inside), and close the windows and doors. Get off equipment immediately. Get out of the water and get away from it. Do not take refuge under any tall, isolated object, such as a tree. Standing under a group of trees shorter than others in the area is better than being in the open. Avoid electric fences, clothes lines, telephone poles and any other conductor. Put down any object that might conduct electricity. If you are outside with no protection get to a low spot, make your body as low to the ground as possible but do not lay flat on the earth. Curl on your side or drop to your knees and bend forward putting your hands on your knees. If there is a group of people, spread out. If someone feels there hairs stand on end, it may mean lightning is about to strike.

If someone is struck by lightning, they do not contain and electrical charge. Provide first aid immediately for any injury that is visible, and be prepared to provide CPR. Immediately call 9-1-1
