- 2. FINDING A SAFE PLACE A house or a building is a safe place. If you are travelling By car or by bus you are safe inside with the windows and Doors of the vehicle shut.
- 3. DO’S AND DONT’S DURING A THUNDERSTORM OUTSIDE Open vehicles like motorbikes, tractors, construction machinery, open cars are not safe. Open fields, tall tress, shelters in parks, elevated places do not protect us from lightning strokes. Carrying an umbrella is not at all a good idea during thunderstorms. If in a forest, take shelter under shorter trees. If no shelter is available and you are in an open field.
- 4. CONTINUATION Stay far away from all trees. Stay away from poles or other metal objects. Do not lie on the ground . Place your hands on your knees with your head between the hands. This position will make you the smallest target to be struck. INSIDE THE HOUSE Lightning can strike telephone cords, electrical wires and metal pipes. During a thunderstorm contact with these should be avoided. It is safer to use mobiles phones and cordless phones. However it is not wise to call up a person through a wired phone. Bathing should be avoided during thunderstorms to avoid contact with running water.
- 5. CONTINUATION Electrical appliances like computers, TVs etc should be unplugged. Electrical lights can remain on. They do not cause any harm. LIGHTNING CONDUCTORS Lightning conductor is a device used to protect buildings from the effect of lightning. A metallic rod, taller than the building, is installed in the walls of the building during construction. One end of the rod is kept out in the air and other is buried deep in the ground. The rod provides easy route for the transfer of electric charge to the ground. The metal columns used during construction, electrical wires and water pipes in the buildings also protect us to an extent. But do not touch them during a thunderstorm.
