Under what condition can the standby diver be deployed as a working diver?

The condition that allows the standby diver to be deployed as a working diver is when the work area is confirmed free of hazards. This ensures the safety of the diver, as it is critical that all potential dangers, such as entanglement risks, water quality issues, or the presence of other underwater obstacles, have been evaluated and eliminated before a diver enters the water for work. The standby diver’s primary role is to provide immediate support and assist in a rescue if necessary, but they can transition to a working role only when it is verified that the environment is safe. This assessment is crucial because divers face numerous risks while working underwater, and ensuring a hazard-free area is a fundamental safety protocol in underwater operations.
