Dangers resulting from extreme
weather Extreme weather conditions can arise so suddenly as to render due preparation virtually impossible. Follow the weather reports and warnings. This can reduce dangers and prevent or minimise damage. Loose branches, trees and roof tiles can always pose a danger in extreme weather. Roads may be flooded in heavy rain. Damage to the carriageway or drain covers lifted by the pressure of the water can subsequently become a danger to vehicles and pedestrians. Notify the fire brigade if hazardous substances such as fuel oil have been released. As general precautions, you should have the following to hand in extreme weather situations: ! ! ! A battery-powered VHF radio with sufficient batteries Battery-powered light sources such as torches and candles Emergency baggage containing important documentation, should you have to leave your home. Tip: The documentation should include photographs or similar of your property. This may be of great assistance to insurance agencies, should your property incur damage. - 80 - Thunderstorms involving lightning discharge entail additional dangers. Note the following precautions here: ! ! ! ! ! ! ! ! ! ! ! ! Avoid tall trees, masts, aerials and similar. Seek shelter in a building. Remain in your vehicle and do not touch any bare metal parts. Remain at a distance of at least 50 metres from overhead power lines. Lightning may result in excess voltage levels. Do not rely entirely on your home’s lightning protection system. Disconnect sensitive devices from the mains or use appropriate overvoltage protection devices. Lightning striking masonry can cause substantial damage and give rise to cracking or fracturing. Heavy thunderstorms sometimes give rise to hail and hurricanes. Additional sources of danger are hailstones and debris and dirt which are entrained by the violently rotating funnel of a hurricane. Note the following precautions in case of hail and hurricanes: Close door or window shutters, keep away from unprotected openings. Go to a low-lying room, e.g. cellar, or a room situated in the building’s interior; cars, caravans and lightweight constructions may not offer adequate protection. Avoid rooms with large roof spans, e.g. halls. Do not remain outside! Go to a solid building! If needs be, lie down with your face to the ground and protect your head and neck with your hands!
