Flood

Water wins every argument. Leave early.

During

  1. If told to leave, leave. Take the go bags.
  2. Never walk or drive through floodwater. 15 cm of moving water can knock you over and 30 cm can float a car.
  3. If trapped, go up, not into a closed attic. Call for help and be visible.

Before

  • Find out now if your home is in a flood zone.
  • Move valuables, documents and chemicals upstairs.
  • Know how to switch off power and gas.

After

  • Floodwater is sewage, fuel and sharp things. Gloves, boots, wash everything.
  • Do not switch power back on until it has been checked.
  • Photograph the damage before cleaning, for insurance.
  • Throw away any food the water touched.
