When some type of disaster occurs, the owners of a store will take measures to protect their business and their property. A lot of places like wal-mart will stack bales of compressed cardboard in front of the doors.
These blocks of compressed cardboard act as a barricade to help stop people from driving cars or trucks through the front doors. Most of the time the front doors of these large stores will be made of glass – which offer little to no protection from a car or truck. During the Rodney King riots, some store owners also used these blocks of cardboard as bullet stops. Its kinda difficult for a bullet to penetrate 3 – 4 feet of compressed cardboard. The store owners were able to band together behind these blocks of cardboard, and stop the crowds of looters from destroying their stores .
This video was filmed just before Hurricane Ike made landfall in Galveston, Texas.
This video shows a real life example of some of the measures that store owners will take to protect their property. This is not a fault of the store owner, the items inside the store is their property and they have the right to defend it.
These bundles of cardboard are best moved by a forklift, or wrap a chain around it and drag it to the desired location with a truck or car. Even though it weighs several hundred pounds, it is not too difficult to move with a little help. If hand power must be used to move the bundle of cardboard, use jacks to get it off the ground, then get some pipes under the block. Then just roll the block on top of the pipes.
