If a diver feels unwell before a dive, what is the appropriate action?

When a diver feels unwell before a dive, the appropriate action is to inform the supervisor and seek medical advice. This response is crucial for several reasons. First and foremost, diving while feeling unwell can pose serious safety risks, not just to the diver but also to their dive team. Conditions such as fatigue, illness, or any kind of discomfort can impair a diver’s judgment, physical ability, and reaction times, potentially leading to dangerous situations underwater.

By communicating their condition to the dive supervisor, the diver ensures that their well-being is prioritized and that the appropriate precautions are taken, be it postponing the dive or arranging for medical assessment. The dive supervisor has the responsibility to evaluate the situation, making decisions based on the safety of the entire team. Taking unnecessary risks by proceeding with the dive or waiting to see if symptoms will improve is not a sound practice, as symptoms could escalate, leading to emergencies during the dive. Thus, this action aligns with established safety protocols and promotes responsible diving practices.
