What is a common misconception about diving with nitrox?

A common misconception about diving with nitrox is that it is always safer than diving with regular air. While nitrox can extend no-decompression limits and reduce the risk of decompression sickness due to its lower inert gas content, it's not inherently safer in all situations. The increased oxygen content in nitrox can also pose risks, such as oxygen toxicity at depths beyond recommended limits.

Diving with nitrox does require understanding its specific use and limitations, including managing the risks associated with higher oxygen levels. Correctly planning dives and adhering to the appropriate depth limits and exposure times is crucial to ensure safety. Hence, while nitrox offers advantages, it does not guarantee safety, which is why this misconception can lead to dangerous practices among divers.
