Increased no-stop time allows divers to stay underwater longer without requiring mandatory decompression stops during their ascent. This enhances the overall safety for long dives because divers can ascend directly to the surface without the risk of decompression sickness, provided they stay within the calculated limits. Consequently, adequate planning becomes essential to ensure that divers remain within these limits and understand their no-stop time during the dive. Careful planning helps divers manage their time underwater effectively, assess their air supply and dive profile, and maintain safety protocols.

While careful planning is crucial for ensuring safety, the increase in no-stop time itself does not inherently increase the risk of nitrogen narcosis or oxygen toxicity, as these risks are mainly associated with dive depth and time at depth rather than no-stop limits. Thus, the need for careful planning becomes even more critical as divers take advantage of extended no-stop times.
