Why do employers stack pallets?

Pallets are stacked for a variety of reasons, but it often boils down to save floor and rack space. Full and partially loaded pallets are often stacked 2-5 pallets high to save space for temporary product storage or for staging prior to transport. Empty pallets are stacked for both immediate use and for long-term storage. However, stacking without proper planning and safety considerations, hazards may be introduced. An area with multiple stacks may be difficult to protect from facility traffic or be difficult to retrieve pallets from the top. Both scenarios could easily lead to a disastrous situation.
