What should divers do if they are at a depth greater than 60 feet?

When divers are at a depth greater than 60 feet, they should prioritize their safety by managing their breathing gas effectively, particularly in scenarios involving potential hypoxia or other complications from breathing air under pressure. At deeper depths, the risk of nitrogen narcosis and oxygen toxicity increases.

By descending to 60 feet and switching to 100% oxygen, divers can help mitigate these risks. Breathing 100% oxygen at that depth allows for the quicker elimination of nitrogen from the body, especially important if divers have been on air, which contains nitrogen that could contribute to decompression sickness upon ascent.

This practice aligns with best safety protocols, as it supports the body's ability to manage excess nitrogen and oxygen levels when transitioning back to shallower depths. Proper gas management is critical to ensure a safe ascent and recovery in diving operations.
