What is the minimum surface interval, in minutes, considered to avoid repetitive dives?

The minimum surface interval of 60 minutes is considered a standard guideline to help avoid the risks associated with repetitive dives. This time allows the body to off-gas nitrogen that has been absorbed during the first dive, significantly reducing the likelihood of decompression sickness on subsequent dives. The 60-minute interval is based on established dive tables and empirical evidence regarding nitrogen loading in the tissues. After this duration, divers have a better chance of ensuring that the nitrogen levels in their bodies have decreased to safer levels before they embark on additional dives. Following these guidelines is crucial for maintaining safety in diving practices, as it helps to prevent the accumulation of excessive nitrogen that could lead to potentially dangerous situations.
