When can a standby diver be deployed for a working dive?

The correct answer involves deploying a standby diver specifically during no-decompression dives of 60 feet of seawater (fsw) or less. This is important for safety protocols in diving operations.

Standby divers serve as a critical safety measure, ready to assist the primary diver if necessary. In scenarios involving no-decompression dives, the conditions allow for more efficient and timely assistance without the complications that can arise in deeper or more complex dives. At depths exceeding 60 fsw, decompression protocols may be involved, which could lead to increased risk and require additional support or resources, making the deployment of a standby diver less straightforward and often necessitating additional planning and safety measures.

Additionally, while standby divers can be an integral part of the safety plan, they are not randomly deployed for any dive or solely upon injury of the primary diver, as safety protocols require consideration of the specific dive conditions and parameters. This reinforces the importance of appropriate training and understanding of dive safety regulations.
