What is the function of a fill station log?

1. Tracking tank usage

2. Indicating responsibility for the Nitrox delivered

3. Documenting weather conditions

4. Calculating dive times

The correct answer is: Indicating responsibility for the Nitrox delivered

The function of a fill station log is essential for documenting and tracking the nitrox delivered to divers. Specifically, it serves to indicate responsibility for the nitrox fills. Each time a tank is filled with nitrox, the log typically records important details such as the blend of the gas, date and time of the fill, the person who filled the tank, and any other relevant data. This information is crucial for maintaining accountability and ensuring that divers receive the correct gas mix needed for their dives. Having a clear log helps prevent mix-ups or mistakes that could lead to improper gas mixtures being used by divers, which could pose serious risks. Additionally, if there is a question or incident related to a dive, the log can provide necessary information regarding what was delivered, allowing for better safety analyses and responses. While tracking tank usage and documenting weather conditions are important in the context of diving, they do not represent the primary purpose of a fill station log. Similarly, calculating dive times is a separate function related to dive planning rather than the fill process itself. Thus, the emphasis on responsibility in the log is what makes it a critical tool at a fill station.
