Disease Prevention Precautions

  • Do not drink water from private wells in the flooded areas. Contaminated flood waters
    may have impacted the private water wells in flooded areas, and the drinking water may not be safe to drink. 
  • Do not eat or drink anything exposed to flood water, or that may have gone bad due to lack of power to your refrigerator. Remember, “When in doubt, toss it out”
  • Minimize skin contact with flood water, especially cuts and sores. Keep them clean and covered.
  • No one should be in flood water; do not allow children to play in flood water. Remember, even shallow rapidly flowing flood water may sweep you off of your feet.
  • Keep contaminated objects, water and hands away from your mouth, eyes and nose.
  • Wash hands frequently with soap and clean water, especially after bathroom use, before eating and immediately following contact with flood water or contaminated objects or surfaces.
  • If you have a private septic system, be aware that you may have trouble flushing your toilet if your yard is flooded. Depending on your specific septic system, the hydraulic pressure from
    the water in your yard may cause the toilet to back up into your house!

Injury Prevention Precautions

  • Do not walk or drive on flooded roads.
  • Turn off main power switches if necessary. Air out and wipe dry all appliances and electrical outlets exposed to water before use.
  • If you have fuel oil or gas systems, ensure tanks are secure and that all lines are free from breaks.
  • Wear rubber boots, gloves and an N95 or HEPA respirator mask during removal and cleanup.
  • Open windows if possible to ventilate and dry the area.  Fans can be used to help with drying.

Mosquito Prevention
•   The large amount of pooled water that remains after a flood provides a breeding ground for mosquitoes. 
•   Be sure doors and window screens are tight fitting and in good repair to keep mosquitoes out.
•   Drain standing water in old tires, tin cans, birdbaths, clean clogged gutters and any other places where mosquitoes might breed.
