When the time-to-surface limit is reached, it is crucial for a diver to begin the ascent. This limit is established to prevent decompression sickness, which can occur if a diver surfaces too quickly after spending time at depth. By ascending, the diver allows their body to safely eliminate excess nitrogen that has been absorbed during the dive.

Slow and controlled ascents, often with stops to allow for the necessary decompression, are essential practices in diving to ensure that the body can safely adjust to the changes in pressure. The ascent should be managed according to specific guidelines—such as a maximum ascent rate and any required safety stops—depending on the depth and duration of the dive. Adhering to these practices helps minimize the risks associated with diving, including those caused by surpassing time-to-surface limits.
