What indicates that a load is improperly rigged?

The indication that a load is improperly rigged is when the load shifts during the lift. This behavior suggests that the rigging equipment is not adequately secured or balanced, which poses significant safety risks. Proper rigging ensures that the weight is evenly distributed and that the load is stable throughout the lifting process. If the load shifts, it may lead to uncontrolled movements, increasing the likelihood of accidents or injuries to personnel nearby and potential damage to the load itself.

The other choices relate to various factors during lifting operations, but they do not necessarily indicate rigging issues. A load that is lighter than expected does not inherently suggest poor rigging practices; instead, it might indicate that the weight was miscalculated. When all personnel are focused on the load, it can imply that they are attentive to safety, rather than suggesting a rigging issue. Additionally, if the equipment functions without issue, it indicates that the machinery is operational but does not reflect on the rigging quality itself. Therefore, the behavior of the load during lifting is the clearest sign of improper rigging.
