After gas analysis and labeling the cylinder, what must the diver do next?

After completing gas analysis and labeling the cylinder, documenting the fill by completing a log entry is crucial for safety and record-keeping. This log entry typically includes details such as the mix of gases in the cylinder, the date and time of the filling, the name of the person who filled the cylinder, and any other relevant notes. This information is essential for tracking the history of the gas used and ensuring that divers are aware of the specific gas mixture they are using, which is particularly important in nitrox diving to avoid potential hazards associated with incorrect gas usage.

Maintaining such accurate records helps divers and dive operations adhere to safety protocols and manage gas mixtures effectively, enhancing both safety and performance during dives.
