, - • <br />M Filling Sandbags <br />Fill the bags about one-half full and tie the bag near the <br />top, if it is tied, which permits the sand to move easily in <br />the bag to create a good dike. Overfilled bags and bags <br />tied too low leave gaps in the dike, which allows water <br />to seep through. Sandbags do not need to be tied unless <br />they are transported. Filling sandbags usually is a two - <br />person operation. One member of the team holds the <br />bag on the ground slightly in front of his or her spread <br />feet and the second shovels the sand into the bag. Use <br />gloves to protect the bag holder's hands. The use of <br />safety goggles is desirable, especially during dry and <br />windy days. For large-scale operations, filling sandbags <br />can be expedited by using bag -holding racks, funnels on <br />the back of dump trucks used for sanding operations and <br />various power loading equipment. However, the special <br />equipment required is not always available during an <br />emergency. <br />M Stacking Sandbags <br />Lift bags using your legs and limit twisting of your back. <br />Gently hand the sandbag to the next person in a sandbag <br />brigade or line. <br />Plan of bottom layer <br />Lapping sandbags <br />.ISO!

Fill the sandbag <br />about one-half full <br />and tie near the top, <br />if it needs to be tied <br />A triangular or pyramid shape for the dike is not <br />necessary if the height will be 1 foot or less. Support the <br />wall of sandbags with "clusters" of bags every 5 feet to <br />stabilize the sandbag wall so it does not tip over from <br />the force exerted by the floodwater. <br />Place the first layer of bags lengthwise on the dike <br />(parallel to the flow), lapping the bags so the filled <br />portion of one bag lies on the unfilled portion of <br />the next, with the tied or open end of the bag facing <br />downstream. Offset adjacent rows or layers by one-half <br />bag length to eliminate continuous joints, similar to what <br />is done laying bricks. Compact and shape each bag by <br />walking on it to develop dike strength and create a tight <br />seal. Continue to walk on the bags as succeeding layers <br />are placed. <br />The base of the dike should be about two to three times <br />as wide as the dike is high to provide adequate strength <br />and friction surface area.
