Block stacking is a palletized storage that does not use any storage equipment. Loaded pallets are placed directly on the floor and built up in stacks on top of one another to a maximum stable height. Ware house safety is one of the primary concerns in warehousing. Therefore it is recommended to have a maximum stable height of stacks e.g. usually not more than six pallets. This aims in preventing accidents of toppling pallets. Bulk storage is done using block stacking. Block stacking can result in the minimum cost of storage since cube utilization is high and no storage medium is required. But in this storing material accessibility is low since only top of the front stack is accessible and loads at the bottom of the stack do not require support. Storage racks are used when support and/or material accessibility is required.
