The spread of disease is a danger following a flood. Continue to exercise caution after a flood:

• Throw away food that has come into contact with flood waters.
• Assume that tap water is contaminated unless officials say it's safe. Boil drinking water before using it. 
• Watch for power lines that are down, and report them to the proper authorities.   
• Stay away from disaster areas - you may hamper rescue or other emergency work.
• Don't walk or drive through flowing water. 
• Use flashlights - not matches or open flames - to examine buildings. There may be flammables or a gas leak inside.
