When should you check your Nitrox fill station log?

Before every dive
Only when you suspect a problem
At the beginning of the diving season
After each dive

The correct answer is: Before every dive

Checking your Nitrox fill station log before every dive is essential to ensure that you have accurate and safe information regarding the nitrox blend you will be using, as well as understanding the critical data such as the partial pressures of oxygen and the blend's maximum operating depth. This practice helps divers verify that the gas they will breathe is appropriate for their dive plan, avoiding miscalculations that could lead to nitrogen narcosis or oxygen toxicity. Frequent checks of the log support thorough pre-dive safety protocols, allowing divers to confirm that the blending process was conducted correctly and that no changes occurred since the last dive. This diligence fosters a culture of safety and ensures that divers are aware of the conditions and quality of their breathing gas at all times.
