What is the recommended response if a diver is ascending too quickly?

The recommended response if a diver is ascending too quickly is to signal the diver to slow down and verify their awareness. This action is crucial because rapid ascents can lead to serious diving-related injuries, including decompression sickness and arterial gas embolism. By signaling the diver, you not only alert them to their speed but also engage them in their ascent process, ensuring they remain aware of their actions and the potential risks involved. This approach promotes safety and encourages adherence to proper ascent protocols, such as making safety stops to allow gases to safely off-gas from the body.

Addressing a diver's ascent speed directly fosters a collaborative environment in which both divers can prioritize safety and well-being.
