The most common damage caused by storms includes fallen trees, torn roofs and water damage caused by heavy rainfall and broken pipes. The Rescue Department assists in clearing damage caused by storms.
When a storm is impending, listen to weather reports and follow the instructions given by the authorities. If you are outdoors, make sure that you are not in the way of falling trees. Keep a distance of at least 20 metres from damaged wires.
As possible, move indoors, close doors and windows, and move away from windows. Unplug electrical appliances. Avoid using elevators in case of sudden power outages.
The minimum supplies to keep at home for extended power outages:
- A flashlight and batteries, candles and matches
- A battery-operated radio to receive information
- Drinking water, food and other necessities such as medicines and sanitary supplies
- Cash. ATM machines do not work and card payments are not possible during a power outage.
- Also keep water aside for the toilet. The toilet can be flushed only once during a power outage. Tap water may not be available during a power outage.
