Which statement correctly reflects a common misconception about diving with nitrox?

The statement that nitrox reduces the risk of all diving accidents reflects a common misconception because, while nitrox can reduce the risk of certain types of diving-related issues, such as nitrogen narcosis and decompression sickness, it does not eliminate these risks altogether. Diving always carries inherent dangers, and several factors—including depth, dive profile, and individual diver physiology—still play significant roles in the overall safety of a dive.

It’s important for divers to understand that using nitrox merely shifts some risks rather than removing them. For example, while the use of nitrox can extend no-decompression limits due to reduced nitrogen input, it also introduces other potential risks, such as oxygen toxicity, particularly at depths exceeding 130 feet (40 meters) for higher concentrations of oxygen. This is why the operational benefits of nitrox should be approached with the same caution as one would with regular air diving.

Divers must be educated on these nuances, which is misleadingly simplified by the idea that nitrox reduces the risk of all diving accidents. Understanding the specific training and knowledge that come with nitrox diving allows divers to effectively mitigate these challenges.
