What should be done if a discrepancy is found in the gas analysis?

If a discrepancy is found in the gas analysis, it is crucial to address the issue before proceeding with the dive. Proper gas analysis is essential for ensuring diver safety, as it verifies that the gas being used is suitable for the specific dive profile and that it will not lead to oxygen toxicity or other problems during the dive.

Ignoring a discrepancy or proceeding with the dive as planned can significantly increase the risk of developing dangerous conditions under water. This could lead to severe consequences, such as decompression sickness or other dive-related injuries. Analyzing and verifying the gas helps to ensure that the correct mix is being used, which is vital for a successful and safe diving experience.

While noting the problem for future reference or notifying just the dive master may seem like a reasonable approach, these actions do not address the immediate concern and can lead to unsafe diving practices. Ensuring that all equipment and gas supplies are properly analyzed and verified before diving is a fundamental aspect of safe diving procedures.
