Raising a beam level by as little as 200 to 300mm can reduce the bays loading capacity by as much as 20%. Modifications and alterations to racking systems can affect the load carrying capacity and reliability of the operation. To maintain operational viability consultation [with a competent person] is to be carried out prior to any modifications or alterations being made so that all relevant safety issues are taken into account.

- Change of type or make of MHE.
- Change in the method of handling unit loads or the pallet type.
- Change in the type of goods handled.
- Change in the weight or size of unit loads.
- Introduction of overhanging loads or load make up accessories.
