Goods stored on pallet racking destined for storage are termed Unit Loads. The design of the pallet should take into account the nature of the goods in the unit load. A change in the pallet design should not be permitted unless the:
a. racking design is suitable to support the weight of the unit load.
b. pallet design keys into the racking and so prevents the unit load from being dislodged.
An assessment of any change to the pallet design should be conducted by a competent person to prevent storage problems arising, such as:changing from timber pallets to post pallets meaning that the legs do not key into racking using pallets larger than allowed for in double pallet racking, as they can overlap pallets behind or push them off their supports using pallets smaller than allowed for in the racking, as they can drop through using skid pallets in racking without timber decks, as they can drop through.Boxes, cartons and other such items stored on pallets should not overhang the pallet. Unit loads on upper levels containing oxes, cartons and other loose loads should be effectively prevented from falling by wrapping, strapping or by some other means.
