TDI Cavern Diver Practice Exam 2025 – Complete Prep Guide

Conducting a search for a lost diver with insufficient gas reserves remaining can pose significant risks to the safety of the rescuers involved. If a diver does not have enough gas to safely conduct a thorough search or to return to safety themselves, then engaging in a search may jeopardize the rescuers' safety and potentially create additional victims. In cavern diving scenarios, the environment can be particularly challenging, and divers must prioritize their own safety along with that of the missing individual.

While the imperative to locate and assist a fellow diver is strong, ensuring that rescuer divers have adequate gas reserves and safety protocols is essential. This perspective emphasizes the importance of a calculated approach that considers the potential dangers of a search operation amidst insufficient gas supplies, underscoring that safety must always come first. Rescuers should be trained to assess the conditions and their own resources before deciding to engage in a search effort.
