Stacking IBC Totes: What You Need to Know
To answer the common question if IBCs can be stacked: yes, IBC totes can be stacked safely one on top of the other and have been engineered to do so. However, it is important to take certain considerations and precautions for the utmost in safety, to prevent any potential damage to the IBCs or cargo and keep hazards out of the stacking process. The considerations include factors such as total IBC weight, the stability of the stacked totes, the use of the appropriate equipment or accessories to stack the totes, and adhering to recommended stacking height limits to prevent overloading or instability.
By taking the proper measures, stacking IBC totes can be carried out safely, efficiently, and with minimalized risk.
IBC Tote Stacking: Notes, Recommendations, and Precautions
- IBC Design: IBC totes are built for stacking as a design feature to optimize space, organization, and work applications. IBCs come with an integrated pallet platform, feet and/or stacking lugs to align and facilitate smooth, in-place stacking. The ability to stack IBC totes is one of the key benefits of an intermediate bulk container.
- Stacking Full Totes: With appropriate safety measures in place, staff training, and knowledge of total weights, full IBC totes can be safely stacked. Full IBCs can be stacked for storage, however guidelines on whether IBCs can be transported both stacked and full vary. We cannot and do not recommend shipping stacked, full IBC totes. It is always important to check either the manufacturer’s guidelines or UN/DOT weight ratings for specific stacking instructions and limitations.
- Stacking Empty Totes: Empty IBC totes can generally be stacked higher than full ones due to weight limits. For example, caged poly IBC totes in 275 and 330 gallon capacities are considered okay to be stacked up to four high when empty and in a storage-type environment. Empty IBC totes are also considered acceptable for stacking in transport given proper restraints are in place.
- Stacking Weight Limits: Almost all IBCs can be stacked at least two high when weighted with cargo. When it comes to stacking three or more cargo-bearing totes on top of each other, it is generally recommended to use smaller-sized totes for better stability and safety. Always adhere to the IBC’s UN/DOT label listed weight limits and manufacturer’s specifications regarding the maximum stacking weight limits.
- Safety Considerations: Always stack IBC totes evenly and securely to prevent accidents and tip overs due to vehicle impact, worker fault, wind, or seismic activity. Also, always inspect your company’s fleet of IBC totes regularly for any signs of damage or wear that could affect their stability and safety for stacking and use.
- Stacking Equipment: Use appropriate equipment, such as forklifts or pallet jacks, for safe and efficient handling to properly position IBCs for stacking.
- Weight Distribution: Consider the total weight distribution of the IBC column when stacking. Heavier totes should always be at the bottom and lighter ones on top.
- Floor Condition: Store and stack IBC totes on a floor that is flat and free from any debris that could cause instability.
- Regulations and Standards: Be aware of and comply with any local or regional regulations and standards that may be in place regarding the stacking of IBC totes, particularly those holding hazardous materials.
