Filling FIBC's are normally filled suspended using a lifting device and with the base of the bag on or near the ground or a pallet. If the FIBC has a discharge spout or other discharging device this should be tied off or closed before filling. It is recommended that the manufacturer or supplier should be consulted before filling at temperatures above 60°C.
Stacking When stacking filled FIBCs, every effort should be made to ensure that the stack is stable. Where possible the stack should be formed against at least 2 retaining walls, preferably 3, to achieve maximum stability; generally the higher the stack the greater the number of retaining walls required. Where only free stacking is possible, a pyramid method should be used. FIBCs should not be pushed into a stack as this can led to damage of FIBCs to the side and behind the FIBC being stowed. The practice can also cause slide damage to webbing lifting loops.
Stacking Height The following aspects should be taken into account when determining the stacking height. This height depends on the pressure developing in the FIBCs stacked at the lower level, the location and the manner in which they are stacked and the stability. If necessary the manufacturer/supplier should be consulted.
Storage Some filled FIBCs are suitable for outdoor storage, others are not. It is most important that manufacturers' recommendations are followed to obtain the maximum possible life and performance from the FIBC and avoid damage to the contents. It is important that stocks of unfilled FIBCs should be rotated on a regular basis in order to avoid the damage and deterioration which may ensure from long-term storage. When filled FIBCs are stored in the open particular attention should be paid to the top closure and its method of trying off, the stack should be sheeted over to prevent water collecting on top of the FIBCs, if the FIBCs are to be stored in the open for a prolonged period, protection against ultra violet radiation should be provided by covering with black polyethylene or some other sheeting material of sufficient thickness to prevent the passage of sunlight, and care should be taken to ensure that FIBCs are not standing in water and the area to be used for storage is swept clean of material that could cause damage to the base of FIBCs at the bottom of the stack.
