To decrease the threat of lightning strikes, it is best to install buildings with lightning conductors. If they are already installed, it is recommended that you check whether they are well grounded and in good order;
Switch off all electrical appliances and disconnect aerials.
During a thunderstorm:
Do not use mobile phone;
It is advisable to remain at home; close all windows, doors, chimney flaps and ventilating apertures. Such preventive actions will reduce the risk of ball lightning;
During a thunderstorm, avoid touching any steelwork or pipelines in a building. Stay away from electric wires, aerials, windows, doors and external walls of the house where trees are present;
A car offers good protection from lightning; close the windows and avoid touching any metal parts;
If you are outdoors during a thunderstorm, do not seek shelter under high trees, or near poles or walls of buildings; do not shelter close to lightning conductors, metal towers or high pipe structures, and avoid open hilly areas - it is better to shelter in bushes or to sit on a slope, with your knees clasped in your hands;
When lightning strikes, being near sources of water is especially dangerous. If a thunderstorm begins when you are bathing, fishing, or in a boat, immediately head for the shore;
During a thunderstorm, do not run, do not drive a motorcycle or ride a bicycle, and do not hold metal objects in your hand. Set them aside at a good distance and wait for the thunderstorm to abate.
If you encounter ball lightning, stay calm, and do not attempt to approach it. Do not try to touch it with any object as an explosion may occur. Do not try to run as the current of air may draw it towards you.
