The Safety Stop in Diving

Why is so Important

Diving is a fascinating activity, but it also carries risks if proper protocols aren’t followed. One of the most important—and sometimes underestimated—procedures is the safety stop. In this article, we’ll explore why it’s essential, how to perform it correctly, and what benefits it provides for your safety underwater.

What Is a Safety Stop?

A safety stop is a pause during ascent, typically at 5-6 meters deep, lasting 3-5 minutes. Although many dive tables don’t require it for no-decompression dives, it’s a practice highly recommended by agencies like PADI, SSI, and NAUI to minimize risks.

5 Reasons Why You Should Do It

Eliminates Residual Nitrogen
During a dive, we breathe compressed air, which causes nitrogen to accumulate in our tissues. As we ascend, this gas must be released slowly to prevent the formation of dangerous bubbles. The safety stop allows for controlled off-gassing, reducing the risk of decompression sickness (DCS).
Provides a Safety Margin
Even if a dive is within "no-decompression" limits, factors like
Intense exercise (swimming against a current).
Cold (which reduces circulation).
Dehydration.
can increase nitrogen buildup. The safety stop acts as a buffer.
Helps Control Ascent Speed
According to Boyle’s Law, pressure changes most drastically in the last 10 meters. A stop at 5-6 meters allows you to
Adjust ascent speed (no faster than 9 m/min).
Avoid accidental rapid ascents, which could cause barotrauma or DCS.
Reduces the Risk of "Silent" DCS
Some microbubbles don’t cause immediate symptoms but can grow and cause issues hours later. The safety stop helps eliminate them before surfacing.
How to Perform a Safety Stop Correctly

At 5-6 meters, halt your ascent and maintain depth.
Use a line or the surroundings (like a reef) to stabilize yourself if there’s current. Maintain good neutral buoyancy.
Monitor your watch or computer 3-5 minutes is sufficient for recreational dives.
Breathe slowly and deeply to maximize nitrogen elimination.
Check on your buddy before continuing the ascent.
Is the Safety Stop Mandatory?

In recreational diving It’s not technically mandatory but highly recommended.
In technical diving Decompression stops are calculated and required.
Some divers skip it due to haste or overconfidence, but data shows it significantly reduces accidents.

Conclusion A Small Step That Saves Lives

The safety stop is like a seatbelt in a car—even if it doesn’t always "seem necessary," it’s crucial in an emergency. Investing 3-5 minutes in it can make the difference between a safe dive and a preventable accident.
