What is a common hazard to avoid while handling permanent lines in a cave setting?

When handling permanent lines in a cave setting, ensuring that lines do not tangle is crucial for several reasons. Tangling can create confusion and impede navigation, which is particularly dangerous in potentially disorienting environments like caves. A tangled line might lead a diver to lose track of their route or get caught, causing panic or disorientation.

Additionally, permanent lines are typically part of a system designed for safety, guiding divers back to an exit or safe location. If these lines are tangled, it could obstruct access to this critical safety system, leading to potentially dangerous situations, especially in low visibility or tight spaces.

Thus, maintaining the integrity of the line, avoiding tangles, and keeping it organized are essential practices to ensure safety and facilitate effective navigation in a cave diving environment.
