Only stack FIBCs if they are designed to be stacked, you are sure of their stability and they are stacked using a “Pyramid” or “Supported” stacking method:
- Pyramid Stacking: Each bag above the first layer must sit on at least four lower bags. Each layer is subsequently tiered inwards forming a pyramid structure.
- Supported Stacking: Formed against two retaining walls of sufficient strength.
Never approach or repair a damaged bag without first removing all bags stacked on top.
