What safety measure is recommended after using EANx tanks?

The recommended safety measure after using EANx tanks is to always check for leaks before use. This practice is crucial because ensuring that there are no leaks helps prevent potential hazards related to handling enriched air nitrox. EANx mixtures have a higher oxygen content than regular air, which increases fire risk and can lead to equipment failure if leaks are present. By checking for leaks, divers can ensure their equipment is safe and functional before their next dive, thereby promoting safety and minimizing accidents.

Other responses may not contribute to safety in diving practices. For instance, unmarked storage locations can lead to confusion about tank contents, increasing safety risks. Ignoring pressure gauges is dangerous as it prevents divers from monitoring air supply effectively. Lastly, using any available tank for any dive can lead to using the wrong gas mix, potentially resulting in serious health risks such as oxygen toxicity.
