Preparing for a Flood     During and After the Flood     After the Flood

The following is information you need to stay safe in case a flood happens near you.

Before a Flood

  • Listen to a radio or television for the latest storm information.

  • Fill bathtubs, sinks, and jugs with clean water in case water becomes contaminated. Sanitize the sinks first by using bleach. Rinse and then fill with clean water.

  • Bring things indoors.

  • Move valuables, such as jewelry, papers, and pictures to upper floors or higher elevations.

During the Flood

  • Do not drive through a flooded area. If you come upon a flooded road, turn around and go another way.

  • Do not walk through flooded areas.

  • Stay away from downed power lines and electrical wires.

  • Watch for animals, especially snakes.

After the Flood

  • Before entering a building, check for structural damage. Don’t enter if there is a chance the building may collapse.

  • Upon entering a building, do not use candles, cigarette lighters, matches, or other open flames, since gas may be trapped inside. Instead use a flashlight.

  • Flood waters pick up sewage and chemicals from surrounding areas. If your home has been flooded, protect your family’s health by cleaning up your house right way. Throw out food and medicine that may have come into contact with flood water.

  • Until local authorities say that your water supply is safe, vigorously boil water five minutes before drinking it or using it for food preparation.

  • Watch for steps and floors that are slippery with mud and covered with debris, including broken glass and nails.
