Who is responsible for performing or verifying a final gas analysis and recording the pertinent information?

The end user is responsible for performing or verifying a final gas analysis and recording the pertinent information due to their direct involvement with the gas being used during dives. This responsibility is crucial to ensure safety and adherence to dive plans. Accurate gas analysis is essential for determining the appropriate use of Nitrox mixtures, as different blends can have implications on the limitations related to maximum operating depth and the potential for oxygen toxicity.

Performing a final gas analysis helps the diver confirm that the gas tank contains the expected percentage of oxygen and nitrogen, allowing them to plan their dive accordingly. In the context of diving, having the end user handle this verification empowers them to take personal responsibility for their safety and dive readiness. Understanding gas mixtures and their effects is a critical part of dive training that end users, as certified divers, must grasp thoroughly to ensure safe diving practices.

The roles of technicians, manufacturers, and instructors, while important, focus on other aspects of the diving process and training. Technicians may assist in the filling of tanks and are responsible for equipment maintenance, manufacturers produce the equipment and gases but do not typically perform on-site analysis, and instructors guide the learning process but do not perform the analysis for the divers themselves. Ultimately, confirmation of gas composition by the end user directly
