What is the minimum manning requirement for SCUBA operations?

The minimum manning requirement for SCUBA operations typically includes a diver, a supervisor, and other support personnel to ensure safety and effective operation during diving activities. The correct answer identifies a configuration that includes a surface supervisor (SUP), a diver, a tender, and a standby diver, which collectively fulfills the safety protocols required for these operations.

Having a supervisor on the surface ensures that there is someone responsible for monitoring the safety of the diver and managing the operation. The tender is essential as they assist the diver during the dive, handling equipment and providing necessary support, while the standby diver is crucial for emergency situations, standing ready to assist if the primary diver encounters difficulty. This layered approach of personnel not only enhances safety but also allows for efficient response in case of emergencies.

This answer highlights the importance of having multiple roles filled by qualified individuals, contributing to a safe diving environment, and thus reflects the best practices as outlined within SCUBA operational guidelines.
