When planning dives using EANx, which safety measure is crucial?

When planning dives using EANx (Enriched Air Nitrox), performing pre-dive buddy checks is crucial as it ensures that both divers are familiar with their equipment, air supply, and dive plan. This collaborative safety measure helps to verify that both divers are properly equipped and ready to handle the dive's specific requirements, especially when using enriched air which has different oxygen and nitrogen levels compared to regular air.

Engaging in pre-dive checks allows divers to discuss their respective dive computers, verify gas mixes, and confirm the planned depth and duration of the dive, which are particularly important when using EANx. This is essential for minimizing risks related to oxygen toxicity and ensuring that both divers are aware of their no-decompression limits and any necessary dive profiles. Overall, buddy checks promote open communication, enhance safety awareness, and allow divers to address any concerns before entering the water.
