The text at the bottom of the poster reads...
"Positive" lightning bolts come from the upper parts of thunderstorms and can strike several miles away.
If you hear thunder then lightning is near. Follow these safety rules!
1. Get inside a house, large shelter or an all-metal vehicle (not a convertible). 2. Only use the telephone in an emergency. 3. Remain clear of tall, isolated trees and telephone poles. 4. Stay away from wire fences, clotheslines or metal pipes and rails. 5. If you are caught outside, away from shelter, and you feel your hair stand on end, squat down, tuck your head as low as you can, and cover your ears. DO NOT LIE FLAT ON THE GROUND. 6. Follow the 30/30 rule: if you hear thunder 30 seconds after seeing the flash, move indoors quickly. stay indoors until 30 minutes after the last thunder is heard.
Some common lightning myths. A. Benjamin Franklin's kite was NEVER struck by lightning! B. Lightning does NOT ALWAYS strike the tallest object, only the tallest object in a particular area. C. Lightning can strike ANY object in its path, not just metal only. D. Just because it is not raining at your location and you hear thunder, it is possible for you to be struck by lightning. In fact, most people stuck by lightning each year are in rain free areas around thunderstorms. E. Rubber sole shoes (or rubber tires) offer no protection from lighting by acting as an insulator.
