Are Nitrox dives inherently safer than air dives?

Nitrox dives are not inherently safer than air dives because they introduce specific risks associated with elevated oxygen levels. While nitrox can reduce the incidence of nitrogen narcosis and allow for longer bottom times at certain depths due to a reduced nitrogen content, it also carries a risk of oxygen toxicity if the Partial Pressure of Oxygen (PPO2) exceeds safe levels. This is particularly important at depths greater than 30 feet, where the increased pressure can elevate PPO2 levels to a point where they can become hazardous.

Furthermore, divers must be well-versed in the use of nitrox, including the proper mixing, analyzing, and understanding of no-decompression limits for different gas mixtures. The safety of a dive ultimately relies on the diver's training, planning, and execution, regardless of whether they are using nitrox or air. Therefore, while nitrox has its advantages, divers need to be knowledgeable and attentive to the unique risks it presents.
