During the dive plan of spring diving, what is the minimum reserve gas that a team must carry if they plan to consume 2800 L?

In cavern diving, it’s essential for divers to maintain a safe reserve of gas to handle any unforeseen circumstances, such as needing to adjust their dive plan or encountering difficulties during the ascent. The minimum reserve gas is often calculated to help ensure that divers can return safely to the entry point without running out of air, especially in a controlled environment like a cavern where conditions can change quickly.

If the team plans to consume 2800 liters of gas during the dive, a common practice in diving safety is to have a reserve that is at least 50% of the planned consumption. Therefore, to ensure safety, the team should have at least 1400 liters as a minimum reserve. This reserve allows divers the necessary breathing gas to make it back safely and handle any unexpected situations they may encounter.

Other potential answers do not provide a reserve that aligns with standard safety practices. For example, having 2000 liters or more may unnecessarily increase the weight and bulk a diver has to manage, while having a reserve of 800 liters or 1000 liters would not meet the safety requirement of having sufficient gas for a safe ascent and possible contingencies. This careful consideration of reserve gas is vital for safety in cavern diving scenarios.
