At what maximum depth is EAN32 typically recommended?

EAN32, or Enriched Air Nitrox 32%, is often recommended for recreational diving at a maximum depth of approximately 30 meters (100 feet). This is largely due to the balance between oxygen exposure and the benefits of reduced nitrogen uptake, which Nitrox provides.

At this depth, divers can enjoy a longer bottom time compared to regular air because the increased oxygen content allows for a reduced partial pressure of nitrogen. This is critical in preventing nitrogen narcosis and minimizing the risk of decompression sickness.

Depths beyond 30 meters increase the risk of oxygen toxicity due to higher partial pressures of oxygen. This potential risk makes it less advisable to use EAN32 at those depths in recreational diving scenarios. While some divers may push limits or have different training considerations allowing deeper dives on EAN32, the general recommendation for recreational divers remains focused around that 30-meter mark.

The other options suggest depth ranges where divers may encounter increased risks associated with oxygen toxicity or where traditional air diving practices would be more commonly recommended.
