🧰 What to do

Before

  • •Know if you're in a flood zone and your evacuation route
  • •Move valuables and chemicals to higher floors
  • •Consider flood insurance — standard policies don't cover floods

During

  • •Turn Around, Don't Drown — never drive through flooded roads
  • •6 inches of moving water can knock you down; 1 ft floats a car
  • •Move to higher ground; avoid basements and underpasses

After

  • •Avoid floodwater — it may hide debris, sewage, or live wires
  • •Don't use wet electrical devices before inspection
  • •Photograph damage; discard food touched by floodwater
