Knowing the center of gravity of a load is crucial because it directly impacts the stability and safety of the lifting process. The center of gravity is the point where the weight of the load is evenly distributed in all directions. By understanding this point, riggers can ensure that the load remains balanced during lifting and movement. If the load shifts or is unbalanced, it can lead to tipping, swinging, or even dropping the load, which poses significant risks to personnel and equipment. Maintaining stability is essential for safe operations in any lifting scenario.

The other options, while they may seem relevant to handling a load, do not address the critical role the center of gravity plays in ensuring safe and effective lifting practices. Calculating the weight of the load or determining its material may be necessary for planning, but they do not directly influence the balance and stability during lifting. Furthermore, measuring the height of the load is important for clearance and ensuring proper lifting protocols, but again, this does not relate to the central aspect of load stability that the center of gravity does. Understanding and utilizing the center of gravity is a fundamental principle in rigging that helps prevent accidents and ensures operational efficiency.
