What is a known danger when lifting a load over personnel?

Lifting a load over personnel is inherently dangerous because of the significant risk of injury if the load were to fall. This situation poses a direct threat to anyone positioned beneath the load, as falling objects can cause serious or even fatal injuries. The emphasis on this danger aligns with safety protocols in rigging and lifting operations, which highlight the importance of keeping personnel clear of any overhead lifts. The other options, while they may be relevant to various operational considerations, do not directly address the immediate personal safety risks associated with lifting loads over people. Therefore, the focus on the risk of injury when a load is lifted over personnel is critical in maintaining safe working conditions on a site.
