When diving with EGS SCUBA, the regulator should not be set lower than which pressure?

The rationale for setting the regulator on EGS (Emergency Gas Supply) SCUBA at no less than 135 PSI is based on ensuring an adequate safety margin when utilizing supplemental air systems. Maintaining a regulator pressure above this threshold helps ensure that divers have sufficient gas flow during critical moments, especially during an emergency ascent or when dealing with potential respiratory challenges underwater.

Setting the pressure too low can compromise the dive operation, making it difficult for divers to access necessary airflow, especially in scenarios where they may be exerting themselves or needing to breathe more heavily. In essence, a value of 135 PSI provides reliability and safety, aligning with best practices for diver health and safety under varying breathing conditions.

Parameters like these are essential for divers to understand and implement in order to maintain operational efficiency and ensure safety during dives, especially when involving supplemental air sources. A proper regulator setting helps prevent not only potential equipment failure but also enhances the diver's ability to respond swiftly to changes in their underwater environment.
