What is the requirement for materials that are piled near a roof edge during roofing work?

During roofing work, materials piled near a roof edge must be stable and self-supporting to ensure safety and prevent accidents. This requirement is crucial because unstable piles can lead to shifting or falling materials, which pose risks to workers and others nearby. Properly stacked materials help maintain a safe work environment, allowing workers to focus on their tasks without worrying about potential hazards from the materials.

The stability of the material stack also directly contributes to efficient workflow. When materials are arranged securely, it minimizes interruptions and enhances productivity, as workers can readily access what they need without the risk of materials collapsing.

While stability is critical, other considerations regarding the handling and placement of materials, such as height limitations or the need for platforms, may influence safety practices, but the core requirement is that the materials must be stable and support their own weight without risk of toppling over.
