Instructions
Push a dresser, bed or other piece of heavy furniture against the door of a room to make a barricade. The heavier the object, the more effective the barricade. Improve the barricade and wedge things tightly between the bottom of the door and the floor. A bunched-up sock works well on carpeted floors, while the toe of a rubber-soled shoe works better on a hard floor.
Nail plywood sheets to the exterior of a house and cover all windows and doors to barricade a home. This is a common practice in expectation of a hurricane or extremely high winds.
Pile sandbags to create a barricade against rising water. Fill the bag 2/3 full with sand, then secure the top of the bag by folding it underneath as you place the bag. Place the bags in low-lying areas first, then make the barricade in even rows after you have filled in the lower areas. Construct the barricade with a pyramid-shaped cross-section along moving water. Completely surround a structure with sandbags laid out in a single row, like bricks, in expectation of a still-water flood from a lake or pond.
