What is the minimum personnel required for normal air diving live boating operations from 60-220 fsw?

In the context of diving operations, particularly for live boating activities at depths between 60 to 220 feet of seawater (fsw), safety and effective management of divers are paramount. For this depth range, certain staffing requirements are established to ensure safety, effective communication, and operational efficiency.

The correct choice outlines a minimum staffing requirement that includes one non-diving supervisor, three divers, and two tender/divers. The presence of a non-diving supervisor plays a crucial role in overseeing the operation from the surface, ensuring adherence to safety protocols and managing the overall logistics without being distracted by the diving activities. This non-diving supervisor is essential for maintaining oversight, especially when multiple divers are working simultaneously.

Three divers are needed to ensure proper support and safety measures are in place. This allows for adequate team dynamics and enables the divers to assist each other if any issues arise underwater. Additionally, having two tender/divers on the surface ensures that there are enough personnel to assist with the deployment and recovery of divers, as well as provide immediate support in emergency situations. Tender/divers are trained to respond quickly, which is critical when divers are at greater depths where emergency response can be complicated.

This combination of personnel establishes a robust safety framework, allowing for effective
