What is an essential practice for divers using EANx?

Using any available tank regardless of its contents

Always performing safety stops on ascent

Always performing safety stops on ascent is an essential practice for divers using Enriched Air Nitrox (EANx) because it helps mitigate the risk of decompression sickness (DCS). EANx allows divers to extend their no-decompression limits and reduces nitrogen absorption compared to regular air, but the risks associated with diving still exist. Safety stops, typically made at around 5 meters (15 feet) for 3 to 5 minutes, allow for off-gassing of nitrogen that has been absorbed during the dive. This practice is crucial in promoting safer ascents, especially when diving with nitrox, as it further enhances the safety margin by allowing time for residual nitrogen to be expelled from the body.

In contrast, using any available tank regardless of its contents can lead to dangerous situations, especially if the tank is filled with a gas mixture that is not suitable for the depth or conditions of the dive. Maximizing depth to experience the gas benefits is misleading since EANx is more beneficial at shallower depths where the no-decompression limits can be extended, and the risk of oxygen toxicity increases at greater depths. Sharing gas mixtures with other divers may create confusion and potential hazards if the gas composition does not match the needs of all divers involved. Thus,
