Stacked materials
Improperly stacked materials pose a significant risk of collapse and injury in smaller workspaces where floor space is often at a premium. By implementing consistent storage protocols, you can protect your team from falling hazards and maintain a more organized, efficient environment.
About 100% of related real accidents concentrate in these types.
Key prevention
- Ensure all stacks are placed on level, stable surfaces to prevent shifting or tipping.
- Place heavier items at the bottom of the stack to maintain a low center of gravity.
- Use cross-stacking or interlocking methods to increase the structural integrity of the pile.
- Maintain clear access to emergency exits and fire equipment by keeping stacks away from walkways.
- Limit the height of stacks to ensure they remain stable and do not obstruct overhead lighting or sprinkler systems.
