What is the depth limit for the UBA MK 20 Mod 0 and 1 in surface supplied diving?

The depth limit for the UBA MK 20 Mod 0 and Mod 1 in surface supplied diving is 60 feet of seawater (FSW). This limit is established based on the design and operational capabilities of the diving system, which takes into account the breathing gas management, equipment integrity, and diver safety protocols.

The MK 20 system is engineered for effective performance and safety at this specific depth under normal operational conditions. Exceeding this limit may not only compromise the equipment's functionality but also increase the risks associated with physiological effects from increased pressure, such as nitrogen narcosis or oxygen toxicity.

Understanding the limitations of diving systems is crucial for ensuring diver safety and successful mission execution. The specification of a 60 FSW limit reflects an important aspect of dive planning, enabling divers and support teams to make informed decisions regarding their diving operations.
