What is described as storage that includes solid piled, palletized, rack storage, bin box, and shelf storage in excess of 12' in height?

High piled storage refers to the methods of storing materials that are stacked or arranged at heights exceeding 12 feet. This type of storage is often associated with larger warehouses and industrial settings where maximizing vertical space is crucial for efficiency and inventory management. The description provided encompasses various forms of high piled storage, such as solid piled materials, palletized goods, and different types of racking systems, which can all be utilized to increase storage capacity within a limited floor area.

This method of storage is significant in fire safety considerations, as high piled storage configurations require specific sprinkler system designs and code compliance to mitigate fire risks effectively. Understanding high piled storage is essential for sprinkler fitters, as they must know how to install appropriate sprinkler systems based on the arrangements and heights of stored materials to ensure proper coverage and protection.

The other types of storage mentioned do not specify the height requirement or are used for different storage configurations, hence are not applicable in this context.
