Safety stop discipline
The safety stop is not an option; it is a fundamental part of a controlled ascent. Proper execution turns a mandatory wait into an opportunity for calm.
Treat the stop as part of the dive
A safety stop at 5 metres for at least three minutes is standard practice for all no-decompression dives. Maintain buoyancy control and keep an eye on your air and your buddy throughout.
Why we stop
A safety stop allows the body extra time to off-gas accumulated nitrogen in a controlled manner. While no-decompression limits define the time we can spend at depth, the stop acts as a buffer to reduce the risk of decompression sickness.
By holding at 5 metres, we allow the body's tissues to slowly reach a state of equilibrium with the ambient pressure before reaching the surface, where pressure changes are most rapid.
Staying neutral and focused
The stop requires active buoyancy management. As your cylinder empties, you become more buoyant; adjust your BCD accordingly to maintain a stable depth without using your hands or fins.
Use this time to remain aware of your surroundings. Check for boat traffic above, observe the reef one last time, and ensure you and your buddy remain in contact and comfortable.
When conditions change
If conditions are rough—surging, cold or poor visibility—the stop is even more important. Do not abandon the stop just to get to the surface quickly, unless safety dictates an immediate emergency ascent.
If you are drifting, use a surface marker buoy or stay close to your buddy to maintain a relative position. Discipline here prevents risks that arise from rushing the final minutes of a dive.
