When operating a hoist, it is critical to avoid allowing anyone under a ___ load.

When operating a hoist, it is critical to avoid allowing anyone under a suspended load. A suspended load is one that is being held aloft by a hoisting device and is not resting on a stable surface. This creates a significant hazard, as there is always the risk of the load falling due to mechanical failure, operator error, or unexpected movements. Ensuring that no one is positioned beneath a suspended load is a fundamental safety measure to prevent serious accidents or injuries.

While other options may involve various conditions of loads, a static load refers to something that is at rest, a secured load implies it has been properly tied down or affixed, and a dynamic load involves forces that are changing. However, neither a static load nor a secured load poses the same level of risk as a suspended load, where the potential for falling is present. Therefore, safety protocols emphasize keeping areas beneath suspended loads clear to protect personnel from the inherent dangers these situations present.
