Keep a battery-powered radio tuned to a local station, and follow emergency instructions. 

If the waters start to rise inside your house before you have evacuated, retreat to the second floor, the attic, and if necessary, the roof.  Take dry clothing, a flashlight and a portable radio with you.  Then, wait for help.  Don't try to swim to safety; wait for rescuers to come to you. 

Turn off all utilities at the main power switch and close the main gas valve if evacuation appears necessary.  

Move valuables, such as papers, furs, jewelry, and clothing to upper floors or higher elevations. 

Fill bathtubs, sinks and plastic soda bottles with clean water.  Sanitize the sinks and tubs first by using bleach.  Rinse, then fill with clean water. 

Bring outdoor possessions, such as lawn furniture, grills and trash cans inside, or tie them down securely. 

Do not drive through a flooded area. If you come upon a flooded road, turn around and go another way.  More people drown in their cars than anywhere else. 

Do not walk through flooded areas.  As little as six inches of moving water can knock you off your feet. 

Stay away from downed power fines and electrical wires.  Electrocution is another major source of deaths in floods.  Electric current passes easily through water. 

Look out for animals - especially snakes.  Animals lose their homes in floods, too.  They may seek shelter in yours.

If your home, apartment or business has suffered damage, call the insurance company or agent who handles your flood insurance policy right away to file a claim. 

Before entering a building, check for structural damage.  Don't go in if there is any chance of the building collapsing. 

Upon entering the building, do not use matches, cigarette lighters or any other open flames, since gas may be trapped inside.  Instead, use a flashlight to light your way. 

Keep power off until an electrician has inspected your system for safety. 

Flood waters pick up sewage and chemicals from roads, farms and factories. If your home has been flooded, protect your family’s health by cleaning up your house right away.  Throw out foods and medicines that may have come into contact with flood water. 

Until local authorities proclaim your water supply to be safe, boil water for drinking and food preparation vigorously for five minutes before using. 

Be careful walking around.  After a flood, steps and floors are often slippery with mud and covered with debris, including nails and broken glass. 

Take steps to reduce your risk of future floods.  Make sure to follow local building codes and ordinances when rebuilding, and use flood-resistant materials and techniques to protect yourself and your property from future flood damage.
