What is the purpose of a "Safety Stop" during a dive?

The purpose of a "Safety Stop" during a dive is to enhance safety during ascent. A safety stop typically involves pausing for a few minutes at a depth of about 5 meters (15 feet) before completing the ascent to the surface. This practice is crucial as it allows excess nitrogen that has accumulated in the tissues during the dive to off-gas, reducing the risk of decompression sickness.

By providing this additional time at a shallower depth, divers can further ensure that they are properly off-gassing and minimizing their exposure to potential nitrogen buildup, which is especially important on deeper or longer dives. This precaution helps promote safer diving practices and is often recommended as a standard part of dive planning and execution.

The other choices, while interesting, do not accurately represent the primary role of a safety stop in diving. Taking photos or discussing experiences can happen during the dive but do not contribute to the diver’s safety regarding ascent and nitrogen management. Checking oxygen levels is important for gas management but is not related to the safety stop specifically.
