Can a complex traverse be completed if a team member reaches their turn pressure before the first dive's turn point?

If a team member reaches their turn pressure before the first dive's turn point, the principle of dive safety dictates that the dive must be aborted. This principle is grounded in the need to maintain safety and ensure that all divers can return within their limits. If one diver reaches their turn pressure, it indicates that they are approaching a critical limit for their gas supply, which could put them at risk of not having enough gas for the return to the surface or minimizing decompression obligations.

Completing the dive under these circumstances could lead to unsafe conditions, where the diver might face the potential for running low on gas or exceeding safe ascent rates. Therefore, the entire team must adhere to the strictest safety guidelines, ensuring that no diver puts themselves at an increased risk. Thus, the safest and most responsible course of action is to abort the dive when a diver reaches their turn pressure before the designated turn point.
