The American Red Cross says to follow these safety guidelines. As the storm approaches: E Find shelter, either in a car or building. E Make sure to unplug your appliances and try not to use electronic devices. E Try to avoid showering or running water. If you are outside during a storm: E Make sure to stay clear of high ground; tall, solitary trees and metal objects, such as fences. E Look for a safe building, but do not seek refuge in a dugout, shed or picnic shelter. E If you are in water, either swimming or boating, get to land immediately. If someone is struck by lightning: E Immediately call 911 or the local Emergency Medical Services (EMS) number. E Give first aid. If the person has stopped breathing, begin rescue breathing. If the heart has stopped, however, let a trained person do CPR. E Look for other injuries or burns. Even though the person received an electric shock, the electrical charge is not retained and the person can be handled safely.
