Why is it essential to have a dive plan when using EANx?

• A. To improve physical fitness
• B. To ensure adherence to social safety norms
• C. To outline the maximum allowed dive times and depths
• D. To compete with other divers

Answer: (C)

Having a dive plan is crucial when using Enriched Air Nitrox (EANx) because it provides clear guidelines on the maximum allowed dive times and depths for the specific Nitrox blend being used. Different Nitrox mixtures have varying percentages of oxygen, affecting the maximum operating depth (MOD) and no-decompression limits (NDLs) for each dive. Establishing a dive plan helps divers avoid inadvertently exceeding these limits, which can lead to oxygen toxicity or other serious diving-related issues such as decompression sickness. Planning dives involves calculating proper dive profiles based on the chosen gas mixture, ensuring that divers stay within safe operational parameters. It also allows for the assessment of dive conditions and personal readiness, contributing to overall safety during the dive. By emphasizing the importance of a defined and well-understood dive plan, divers can maximize the benefits of using EANx while minimizing risks associated with mixed gas diving.
