Which of the following is a common risk when rigging?

Unbalanced loads pose a significant risk in rigging practices because they can lead to unexpected shifts in weight and direction during lifting operations. When a load is not evenly distributed, it may cause the rigging equipment, including slings, hooks, and cranes, to become unstable or overloaded. This instability can increase the likelihood of dropping the load, which poses a danger not only to the riggers but also to other personnel in the vicinity and any equipment or structures below.

Addressing the issue of unbalanced loads is critical for ensuring safety in rigging operations. Proper load assessment and management techniques, such as load calculations and the use of appropriate rigging gear, can help mitigate this risk. The emphasis on balancing loads is a key tenet of safe rigging practices and is well understood by trained personnel in the field.

The other options, while they may present challenges, do not directly impact the immediate physical safety in the way that an unbalanced load does. For example, using excessive manpower may lead to inefficiencies but does not inherently create a safety hazard unless it leads to operator fatigue. Similarly, over-scheduling lifting tasks can lead to rushed operations and potential errors, but it is not an immediate risk like an unbalanced load. Lastly, using too
