Following the tragic incident in which two people were struck dead by lightening in a church , I decided to put up this list, hopefully it will save someone's life. Lightening strikes occur more frequently than people think and here are simple was to keep yourself safe:

Pay attention to the weather. The best way to avoid being struck by lightening is to stay away from storms. Always check the weather forecast before heading outdoors. If you notice that it may rain, be sure to arrive home as soon as possible or cancel the event. Even if there are no predictions of a storm, keep an eye on the clouds, ast he forecast is not always accurate. Whenever participating in outdoor activities, such as camping or hiking, be aware of the weather. Depending on your location, the weather may quickly change. Always be prepared to escape from a storm.

Avoid open areas and tall objects. The taller the object, the more likely lightening will hit it, and the electricity might jump to you. Elevated or watery areas are also unsafe, as there is a higher chance of you being hit by lightening. It's recommended that you take shelter in lower, dry areas. Stay low by crouching with your head in between your knees and covering your ears with your hands. Press your heels together, as this will prevent electricity from reaching your heart if you're struck. Avoid completely flattening yourself on the ground.

Stay away from objects that may conduct electricity. Fences and metal poles are examples that are commonly found outdoors. If you're carrying metal objects that stick out, quickly remove them. While smaller metal items, such as piercings or electronic devices, are of no risk, the ones that protrude from you and are isolated endanger you. Umbrellas are an example.

Take shelter in a car. Although they're mostly made of metal, they're one of the safest places to be during storms. If the car is struck by lightening, it will travel through the metal in the car and around your body (not through it) and safely into the ground. Place your hands in your lap, and don't let your body come into contact with the items inside, such as the steering wheel or door handles.

Use proper housing materials.

A lightning rod is a tall, metal rod that
is placed on a building's roof. It has a copper wire running through it that connects to a conductive grid buried underground. When lightning strikes it, it causes the electricity to run through the rod and into the grid. This system helps to carry the electricity away from the building and into the ground, rendering it harmless..

WHEN INDOOR.
Don't use any wired appliance or device. Wireless appliances (cordless phones, razors, etc) are safe to use. Stay away from water pipes and faucets. (No baths, showers, etc.) Don't stand on a basement floor or patio slab, or anywhere where standing water or excessive moisture is present. These areas are 'ground current' danger zones. Stay away from walls where electrical wiring is present. Lightning will occasionally jump through the air inside a house or building to reach a better grounding path, such as from electrical wires to a water pipe.

Another tip from our very own Nairalander:
To calculate your nearness to a lightening part in the middle of a thunder storm. Get a stop watch and time the duration between a flash of lightening and the clap of thunder that follows. Divide by 5.. If your answer falls below 0.5 try stay inside if its above 0.6 upwards you are good. The less the value the more chance of danger- JOHNYDON22
