Which of the following is NOT a factor when making submerged lifts?

When considering submerged lifts, various factors come into play that can impact the safety and effectiveness of the operation. Buoyancy is crucial as it determines how objects will float or sink in water, which directly influences how they can be lifted and stabilized. Wave action impacts the conditions under which a lift can safely be performed, as it affects visibility, load stability, and the overall safety of the operation. Ground stability is essential for ensuring that the lifting equipment remains safe and secure throughout the lifting process, preventing accidents due to shifting or sinking.

Water temperature, while it may have an influence on certain properties of materials or equipment, does not directly affect the mechanics of the lift itself, such as buoyancy or stability under water, in the way that the other factors do. Therefore, it is not a critical factor in the planning and execution of submerged lifts compared to the stability of the ground, action of waves, and buoyancy of the materials involved.
