Follow the instructions of the authorities before taking any action, like going back to the house, shovelling mud, emptying water from basements, etc.
Do not pass along flooded roads: there may be chasms, potholes, open manholes or severed wires. In addition, water may be contaminated by fuel or other substances
Pay attention to areas where the water has receded: the road surface may be weakened and collapse
Check to see if you can reactivate the gas and the electrical system. If necessary, ask for the advice of a technician
Before using the sewage systems, gather information on whether drainage systems, septic tanks and wells are not damaged
Before drinking tap water make sure that municipal ordinances or warnings do not prohibit it; do not eat food that have come into contact with floodwater: it could be contaminated
Learn which is the correct behaviour in case of alert, during a flood and right after it
