What is a major disadvantage of using unimproved open storage?

The choice indicating that a major disadvantage of using unimproved open storage is the limited use of material handling equipment (MHE) reflects a fundamental issue with this storage method. Unimproved open storage typically refers to areas not specifically designed or equipped for efficient handling or protection of materials. In such environments, the lack of proper infrastructure impedes the capability to use advanced MHE effectively.

Without enhancements like paved surfaces, defined aisles, or appropriate lifting equipment, operations can be slowed down and less efficient. For example, the absence of proper surfaces may lead to increased wear and tear on equipment, and it can restrict the movement of forklifts and other MHE due to ground conditions. This limitation directly impacts the speed and efficiency of material handling processes, making it more challenging to access, store, and organize inventory effectively.

In contrast, the other options present various challenges that are typically not as central to the definition of unimproved open storage. For instance, high costs can often be mitigated through the minimal infrastructure of open storage, and while security measures may vary, they are not inherently tied to the structure itself in the same way limited MHE usage is. Thus, the restricted effectiveness of material handling equipment stands out as a critical disadvantage in the context of
