FLOODS - Most Common Hazards
Floods are one of the most common hazards in the U.S. But all floods are not alike. Riverine floods develop slowly over a period of time. Flash floods can develop quickly, sometimes in a matter of minutes, without any visible signs of rain. Flash floods often have a dangerous wall of roaring water that carries a deadly cargo of rocks, mud and other debris that can sweep away most things in its path. Overland flooding occurs outside a defined river or stream, such as when a levee is breached, but still can be destructive. Flooding an also occur from a dam break producing effects similar to a flash flood. Every state is at risk from this hazard.

BEFORE: 1. Know the terms used to describe flooding:
2. Be prepared to evacuate. Know and practice your emergency plan. 3. Prepare to survive on your own for at least three days. Have your 3-day emergency kit readily available as well as a small emergency kit in your vehicle. Click here for ideas on how to put one together yourself. 4. Listen to radio or television stations for current information. 5. Ask local officials whether your property is a flood-prone or high rish-area. But remember that floods often occur outside high-risk areas. Find out how to protect your home from flooding. 6. Identify dams in your area and determine whether they are a hazard to you. 7. Consider purchasing flood insurance. Just remember there is a 30-day waiting period before flood insurance goes into effect, so don't wait. 8. Consider options for protecting your property.

DURING: 1. Be aware of flash floods. If there is any possibility of a flash flood, move immediately to higher ground. Do not wait for instructions to move. 2. Listen to radio or television stations for current information. 3. Be aware of streams, drainage channels, canyons and other areas known to flood suddenly. 4. If local authorities issue a flood watch, prepare to evacuate:
5. Do not walk through moving water. Six inches of moving water can knock you off your feet. If you must walk in a flooded area, walk where water is not moving. Use a stick to check the firmness of the ground in front of you. 6. Do not drive into flooded areas. Six inches of water will reach the bottom of most passenger cars causing loss of control and possible stalling. A foot of water will float many vehicles. Two feet of water will wash away almost all vehicles. If floodwaters rise around your car, abandon the car and move to higher ground, if you can do so safely. You and your vehicle can be quickly swept away as floodwaters rise. |

AFTER: 1. Avoid floodwaters. The water may be contaminated by oil, gasoline or raw sewage. The water may also be electrically charged from underground or downed power lines. 2. Avoid moving water. 3. Be aware of areas where flood waters have receded. Roads may have weakened and could collapse under the weight of a car. 4. Stay away from downed power lines and report them to the power company. 5. Stay away from designated disaster areas unless authorities ask for volunteers. 6. Return home only when authorities indicate it is safe. Stay out of buildings if surrounded by floodwaters. Use extreme caution when entering buildings. There may be hidden damage particularly in foundations. 7. Consider your family's health and safety needs:
8. Service damaged septic tanks, cesspools, pits, and leaching systems as soon as possible. Damaged sewage systems are serious health hazards. 9. Contact your insurance agent. |
