When lightning approaches, your immediate priority must be to reduce your risk of getting hit.
You and your family are camping. As you are preparing dinner on the camp stove, you hear the rumble of thunder in the distance. You look around and see that your tent nearby and a large picnic shelter is just down the trail. Your car is about Â¼ of a mile away, parked at the trailhead. What should you and your family do?
In this case, the smartest thing to do is to round up your family and get into your car. The tent is not a safe place to be, as it offers NO protection from a lightning strike. The picnic shelter is also not a safe location. Both the tent and picnic shelter will keep you dry but they offer NO protection from a lightning flash. It is best to remain in your vehicle for about 30 minutes after the last rumble of thunder is heard.
People who have been hit by lightning carry no electric charge and can be safely tended to. Also, victims who appear dead can often be revived. If the person is not breathing, begin mouth-to-mouth resuscitation. If a pulse is absent as well and you know cardiopulmonary resuscitation (CPR), begin CPR. Stay with the victim until help arrives.
