Lightning Safety Published Aug. 18, 2017 By Fire Prevention Office 17th Training Wing GOODFELLOW AIR FORCE BASE, Texas -- Thunder and lightning storms happen all the time. Know what to do to keep you and your family safe when storms strike. For outdoor safety: - If you can hear thunder, you are within striking distance of lightning. Look for shelter inside a home, large building or a hard-topped vehicle right away. - Do not go under trees for shelter. There is no place outside that is safe during a thunderstorm. - Wait at least 30 minutes after hearing the last clap of thunder before leaving your shelter. - Stay away from windows, doors and porches. - Places with only overhead protection like sports fields, golf courses, picnic areas and sheds are not safe during a lightning storm. - If someone is struck by lightning call 911 and get medical help right away. For indoor safety: - Turn off computers. - Stay off corded phones. - Don’t come into direct contact with plumbing. - Do not wash your hands, shower, bathe, do laundry or wash dishes.
