How deep can a diver go for operationally necessary dives without notification?

• A. Deeper than 130 fsw
• B. Deeper than 150 fsw
• C. Up to 130 fsw
• D. Up to 190 fsw

Answer: (A)

The correct answer relates to the operational limits established for diving in a military context. Divers are typically permitted to conduct operational dives at depths up to 130 feet of seawater (fsw) without requiring additional notification or supervisory approval. This depth limit is set to ensure that divers remain within safety parameters that allow for effective and efficient operations while mitigating the risk of decompression sickness and other potential underwater hazards. Diving deeper than 130 fsw generally necessitates more rigorous planning, including dive tables and the involvement of supervisors, to account for the increased risks associated with deeper dives, such as longer decompression times and greater physiological stress on divers. Such precautions are crucial to maintaining diver safety and mission effectiveness. Thus, while operational needs may sometimes require deeper dives, notification and proper planning become essential beyond the established limit of 130 fsw.
