Don't use the telephone during the storm. Lightning may strike telephone lines outside. Don't take laundry off the clothesline. Don't work on fences, telephone or power lines, pipelines, or structural steel fabrication. Don't use metal objects like fishing rods and golf clubs.
Golfers wearing cleated shoes are particularly good lightening rods.
Don't handle flammable materials in open containers. Stop tractor work, especially when the tractor is pulling metal equipment, and dismount. Tractors and other implements in metallic contact with the ground are often struck by lightening. Get out of the water and off small boats. Stay in your automobile if you are traveling.
