How Long Should a Safety Stop Be in Scuba Diving?

As you ascend from a scuba dive, the pressure on your body decreases. This can cause nitrogen bubbles to form in your tissues, which can lead to decompression sickness (DCS). A safety stop is a period of time spent at a specific depth during your ascent to allow the nitrogen bubbles to dissolve back into your blood and be safely exhaled.

The recommended length of a safety stop depends on a number of factors, including the depth of your dive, the length of your dive, and your personal fitness level. In general, however, most divers will benefit from a safety stop of 3-5 minutes at a depth of 15-20 feet (5-6 meters).

Benefits of a Safety Stop

There are a number of benefits to performing a safety stop, including:

Reduced risk of DCS: A safety stop can help to reduce the risk of DCS by allowing the nitrogen bubbles in your tissues to dissolve back into your blood and be safely exhaled.
Improved circulation: A safety stop can help to improve circulation by increasing the flow of blood to your muscles and tissues. This can help to reduce fatigue and muscle soreness.
Increased hydration: A safety stop can help to increase hydration by allowing you to drink fluids while you are still underwater. This can help to prevent dehydration, which can lead to fatigue and other health problems.

How to Perform a Safety Stop

Performing a safety stop is simple. Simply ascend to a depth of 15-20 feet (5-6 meters) and remain at that depth for 3-5 minutes. During your safety stop, you should:

Remain in a vertical position: This will help to prevent nitrogen bubbles from forming in your joints and other areas of your body.
Breathe slowly and deeply: This will help to increase the flow of blood to your muscles and tissues and promote the dissolution of nitrogen bubbles.
Drink fluids: This will help to prevent dehydration and improve circulation.

When to Perform a Safety Stop

You should perform a safety stop on every scuba dive, regardless of the depth or length of your dive. However, there are some situations where it is especially important to perform a safety stop, such as:

After a deep dive: A safety stop is especially important after a deep dive, as the risk of DCS is higher.
After a long dive: A safety stop is also important after a long dive, as the longer you spend underwater, the more nitrogen your tissues will absorb.
After a strenuous dive: A safety stop is important after a strenuous dive, as exercise can increase the risk of DCS.

Safety Stop Guidelines

In addition to the general guidelines above, there are a few other things to keep in mind when performing a safety stop:

Do not ascend too quickly: Ascending too quickly can cause nitrogen bubbles to form in your tissues and increase the risk of DCS.
Do not perform a safety stop at a depth that is too shallow: A safety stop at a depth that is too shallow will not be effective in preventing DCS.
Do not perform a safety stop if you are feeling tired or unwell: If you are feeling tired or unwell, it is important to ascend to the surface immediately and seek medical attention.
