The Dangers Of Flood Water.

Flood water is deceptive.  The depth and the speed of the water is not always obvious. If you can not see the bottom of a flooded road do not walk or drive through it.  Flood water can erode and wash away road surfaces leaving deep holes and uneven surfaces which cannot be seen. About 60% of all flood deaths are people in vehicles that moving water sweeps away. Flood water poses drowning risks for everyone, regardless of their ability to swim. Swiftly moving shallow water can be deadly.

Flowing water 

  • Fresh water moving at only 4 mph, a brisk walking pace, exerts a force of about 66 pounds per square foot of anything it encounters;
  • Double the water speed to 8 mph and the force zooms to about 264 pounds per square foot. That’s enough force to punch a car or light truck off a flooded road if the water’s up to door level. Imagine what it would do to a person!flood water dangers prs of tampa bayu
  • Six inches of water will reach the bottom of most passenger cars causing loss of control and possible stalling.

Home septic systems- Do not use the sewage system until water in the soil absorption field is lower than the water level around the house. If you have a home-based or small business and your septic system has received chemicals, take extra precautions to prevent contact with water or inhaling fumes. Proper clean-up depends on the kinds of chemicals in the wastewater.
