and reduces the problems of evacuating large numbers from the . levee In the event of an emergency. Notes If sandbags are filled at a remote location, such as shopping center parking lot, they can be easily moved by stacking the bags on pallets. A pallet of 50 properly filled sandbags has a weight of about 2,000 lbs. This load can be managed by most fork lift trucks and the pallet can be transported to the site by pick-up trucks or other vehicles. By palletizing loads, the time consuming and back- breaking job of handling individual sandbags can be lessened. To be effective, sandbags must be properly filled. The average sandbag measures 14 x 25 inches and is filled approximately half- full to allow for proper stacking and placement. A properly filled sandbag should weigh about 40 lbs., and occupy a space of about 28 cubic feet when tamped into place. Filling sandbags is a tedious and labor intensive project. A sandbag filling station may be constructed to speed the process and plans for one design can be found in the appendix. This station has an average output of l50 bags per hour and uses a crew of 5 workers. The following chart gives the amount of sand and number of bags required for 100 foot linear sandbag cap or wall.
