When should a diver perform a safety stop during ascent?

A safety stop is an important practice for divers as they ascend from a dive to help reduce the risk of decompression sickness, or "the bends." The recommended depth for a safety stop is typically around 5 meters (15 feet). During this stop, which is usually held for about 3 minutes, the diver allows excess nitrogen absorbed during the dive to be safely released from the body as they ascend to shallower depths.

The choice of 5 meters is significant because being at this depth still provides enough pressure to assist in the off-gassing process while being close enough to the surface to ensure the diver can safely complete their ascent. This depth balances safety and practical considerations, as divers are less likely to be affected by currents and can monitor their air supply with ease.

Overall, implementing a safety stop at this depth for the specified duration is a proactive measure that enhances diver safety and contributes to a more enjoyable diving experience.
