Which of the following is true of ramp stockpiles?

The appropriate answer regarding ramp stockpiles is that the ramp must be 15 feet wide or more. This requirement ensures that the ramp provides sufficient stability and safety for heavy equipment maneuvering on and off the stockpile. A width of at least 15 feet allows for adequate space for the equipment to operate and reduces the risk of tipping or losing control, particularly when loads are being moved or when the equipment is transitioning on the ramp.

Wider ramps also facilitate the movement of equipment, making it easier to navigate and reducing the potential for accidents due to tight confines. A less wide ramp might not adequately support the necessary operational needs or safety considerations, making it essential for operators to adhere to the 15-foot width specification.
