What is the fall distance limit for stockpiles containing aggregate classes A, B, and C?

The fall distance limit for stockpiles containing aggregate classes A, B, and C is set at 15 feet. This specification is crucial for ensuring safety during the handling and management of the aggregate materials.

When stockpiling aggregates, there is a risk of material shifting or collapsing, which can pose hazards to workers and equipment. Keeping the fall distance limited to 15 feet helps minimize these risks, ensuring that if material does shift or fall from the stockpile, it does so within a safe range. This distance is a balance between practical operational needs and safety considerations, allowing for efficient handling while preventing accidents that could arise from higher fall distances.

Other options such as 10 feet, 20 feet, and 25 feet either do not align with established guidelines or may not be appropriate for the safe management of these aggregates, which further reinforces 15 feet as the standard and correct distance limit for stockpiles of aggregate classes A, B, and C.
