Follow instructions for what to do before a severe storm
During thunderstorms, you should also stay away from items that conduct electricity, such as telephones, appliances, sinks, bathtubs, radiators and metal pipes.
Do not go out to rescue the laundry on the clothesline because it may conduct electricity.
If you are outdoors when a thunderstorm hits, take shelter immediately, preferably in a building but, failing this, in a depressed area such as a ditch, culvert or cave. Never go under a tree.
