Safety stops are a vital component of scuba diving, serving as a precautionary measure to prevent decompression sickness and ensure a safe ascent. Decompression sickness, also known as "the bends," occurs when dissolved gases, primarily nitrogen, form bubbles in the body due to a rapid decrease in pressure.

Incorporating safety stops into your first dive plan significantly reduces the risk of decompression sickness and creates a safer scuba diving experience.

Preventing Decompression Sickness

Safety stops play a crucial role in preventing decompression sickness by slowing down the ascent rate and allowing excess nitrogen bubbles to dissolve out of the body. When scuba diving, the compressed air you breathe contains nitrogen, dissolving under pressure into your body tissues. As you ascend, the surrounding pressure reduces rapidly, and nitrogen begins to come out of the solution, forming bubbles. By performing a safety stop, you give your body time to release excess of nitrogen bubbles, significantly reducing the risk of decompression sickness.

One might wonder, "If I'm only scuba diving recreationally, do I still need to make a safety stop?" The answer is a resounding yes! Regardless of your dive's depth or gas mixture, every scuba diver should make a safety stop at the end of each dive to prioritize their own safety over any other objectives. Not only does this practice reduce your risk of decompression sickness, but it also instils safe diving habits that will benefit you throughout your scuba diving journey.

Ensuring Safe Ascent

In addition to preventing decompression sickness, safety stops also help divers maintain proper buoyancy and position during ascent, ensuring a safe return to the surface. Adhering to a safe ascent rate is crucial to avoid potential lung overexpansion injuries or decompression sickness. It is highly recommended that the ascent rate of certified diver should not exceed 18 meters per minute as part of safe diving practices.

The final 5 meters of the final ascent is the most dangerous part of the water column for lung overexpansion injuries or decompression sickness. Performing a safety stop at a depth of 5-6 meters for 3-5 minutes gives your body time to adjust to the pressure change, ensuring a safe and controlled final ascent to the surface.

Diving is meant to be an enjoyable experience, and adhering to safety procedures like safety stops will help you stay safe and relish every moment underwater.

How to Perform a Proper Safety Stop

Proper safety stops require divers to find the right depth (5-6 meters) and time their stop (3-5 minutes). The suggested depth for a safety stop is 5 metres, allowing divers to release compressed air underwater and avoid decompression sickness safely. To time your safety stop, you can use a dive computer or a watch to monitor the stop's duration accurately.

While performing a safety stop, it's essential to maintain neutral buoyancy and proper positioning throughout the stop. Holding onto a the mooring line or anchor line also can be beneficial, as it helps you stay at the required depth and maintain your position.

By following these guidelines, you'll be well on your way to mastering the art of the safety stop and ensuring every dive is a safe and enjoyable diving experience.

Finding the Right Depth

Performing safety stops at the correct depth is crucial for a successful and safe ascent. It is suggested that the maximum depth used for a safety stop should be approximately 5 meters. This depth allows your body to release excess nitrogen accumulated during the dive, reducing the risk of decompression sickness.

To find the right depth for your safety stop, you can use a depth gauge or dive computer to monitor your depth accurately. Maintaining proper buoyancy control is also essential to stay at the same level throughout the safety stop. Ensuring that you perform your safety stop at the right depth can significantly reduce the risk of decompression sickness and enjoy a safe and comfortable ascent.

Timing Your Stop

Timing your safety stop is essential to guarantee a secure ascent and evade decompression sickness. The recommended duration for a safety stop is between 3 to 5 minutes, even during recreational dives. To ensure you time your stop correctly, you can use a dive computer or a watch to accurately monitor the stop's duration.

By timing your stop correctly, you give your body enough time to release excess nitrogen, reducing the risk of decompression sickness. Additionally, it helps you maintain proper buoyancy and positioning during the safety stop, ensuring a smooth and secure ascent to the surface.

Maintaining Buoyancy and Position

Maintaining proper buoyancy and position during a safety stop is crucial to guarantee a secure ascent to the surface. To maintain appropriate buoyancy during a safety stop, you can remain level with the individual holding the safety sausage reel or use a dive computer to monitor depth.

During a safety stop, it's essential to monitor chest level with your depth gauge or dive computer to ensure you remain at the same level or specified depth and do not inadvertently ascend to the surface. Venting air from the BCD during ascent establishes neutral buoyancy and ensures a slow ascent.

By maintaining proper buoyancy and position, you can ensure a safe and comfortable ascent to the surface.

Recreational divers should be aware of special considerations when performing safety stops, such as shallow water, dives and safety stops, shore diving, diving in currents, and diving after a missed safety stop. By understanding and addressing these specific circumstances, recreational divers can ensure a safe and enjoyable diving experience while minimizing the risk of decompression sickness.

Let's explore these special considerations and how scuba divers, particularly recreational divers, can adapt their safety stop practices to accommodate these unique situations.

Shallow Dives and Safety Stops

Safety stops are strongly encouraged on every dive, including shallow dives. While there is no particular relationship between shallow dives and safety stops, safety stops enable divers to adjust their buoyancy before rising the last 5 meters of the water column and allow the body to off-gas nitrogen accumulated in the tissues while at depth.

By performing safety stops on shallow dives, divers can accurately adjust their buoyancy before ascending the final 5 meters, facilitating the release of nitrogen accumulated in the blood vessels and tissues at depth. This practice not only contributes to a safer ascent but also instils safe diving habits that will benefit recreational divers throughout their diving journey.

Shore Diving

Safety stops are equally important during shore dives, as they help prevent decompression sickness and ensure a safe ascent. To effectively execute safety stops while shore diving, making a vertical safety stop at the end of each dive is recommended, maintaining a depth of 5 meters for three to five minutes. As you ascend slowly, achieve neutral buoyancy by exhaling and releasing compressed air out from your BCD. However, during a shore dive, divers may still move horizontally towards the exit point or swim around at the 5-meter mark. It's prudent to check your dive computer to maintain the 5-meter depth continually, and if necessary, adjust your BCD to avoid accidentally floating to the surface.

In Sydney, many new divers primarily engage in shore dives at the beginning of their diving journey, with Oak Park and Bare Island being two of the most commonly dived sites for beginners. Both sites have similar dive profiles, and new divers might not observe other divers making a noticeable safety stop, even though these divers are still performing one while swimming at the 5-meter mark for the last 5-10 minutes of the dive. The problem arises when they transition to deep boat diving, as they risk forgetting about the importance of a physical safety stop.

By following these guidelines and recommendations, recreational divers can ensure a safe and enjoyable diving experience when diving from the shore.

Diving in Currents

Performing safety stops in currents can be challenging, but it is crucial to prioritize safety in these situations. If the current is too strong, utilising a surface marker buoy (SMB) for a drifting stop is advised, enabling you to remain in one location and fulfil your decompression and safety stops.

When swimming in a current, it is suggested that one swim vigorously into the current rather than remain close to the surface of the water at the conclusion of the dive. This will enable one to remain in command and complete the safety stop, ensuring a safe ascent and minimizing the risk of decompression sickness.

Diving After a Missed Safety Stop

If a diver neglects to perform a safety stop, they are advised to abstain from scuba diving for the remainder of the day and observe themselves for signs of decompression sickness. Diving after a missed safety stop or decompression illness can pose potential risks, and it is essential to evaluate the potential risks and benefits before making a decision based on the specifics of the dive and the diver's experience level.

By being cautious and mindful of the risks associated with diving after a missed safety stop, recreational divers can prioritize their safety and well-being while enjoying the underwater world.

Summary

In conclusion, safety stops play a critical role in scuba diving, helping prevent decompression sickness and ensuring a safe ascent. By following best practices, using dive computers, and addressing special considerations for recreational divers, you can make every safety stop a successful one. Remember, scuba diving is meant to be an enjoyable experience, and adhering to safety procedures like safety stops will help you stay safe and relish every moment underwater.

So, whether you're a seasoned diver or just starting, make sure to prioritize safety stops and follow the guidelines we've discussed in this blog post. By doing so, you'll not only enhance your diving experience but also ensure the safety and well-being of yourself and your diving buddies.

Frequently Asked Questions

What is a safety stop in diving?

A safety stop is a pause that scuba divers make while they are returning to the surface after a dive. This short break usually occurs at a depth of 5 metres for between three and five minutes and helps the diver's body decompress from the effects of the dive.

This is a critical step in safe diving practices. It allows the diver to adjust to the pressure changes and helps to reduce the risk of decompression sickness. It also gives the diver a chance to check their equipment and make sure everything is in order.

What is a 3-minute safety stop in diving?

A 3-minute safety stop in diving is a pause at a depth of 5-6 metres for three to five minutes, allowing the diver’s body to decompress and unload nitrogen accumulated during the dive. It is an important part of the safety procedures for all dives below 10 meters.

Safety stops are highly recommended for all dives deeper than 10 meters and are mandatory for dives deeper than 30 meters. The purpose of the air and safety stop is to reduce the risk of decompression sickness, which can occur when nitrogen is released too quickly from the body. The safety stop also allows the diver to check their depth and air supply.

What is the difference between a decompression stop and a safety stop?

Decompression and Safety Stops are two different procedures when diving. A Decompression Stop is absolutely necessary after a deep dive and is intended to allow for the nitrogen in your body to be released slowly and prevent decompression sickness.

Meanwhile, a Safety Stop is an extra safety measure at the end of a non-deco recreational dive.

How deep can you dive without decompression stop?

The maximum safe dive depth for no-stop diving is 40 Meters. While it is possible to go deeper, the no-stop times are so short that attempting this would not be within safe diving limits under surface conditions. It is strongly advised to adhere to the 40 meters limit when diving without a decompression.

If you are a recreational diver, making a safety stop on all dives is important. This is a simple and effective way to reduce your risk of decompression sickness and ensure a safe and enjoyable dive.

What depth do you have to do a safety stop?

To complete a safety stop, you should stop your dive at a depth of 5-6 metres for three to five minutes. This deep stop allows the body to release any excess nitrogen built up during the dive and adds an extra five metres of layer of safety to your dive profile.

Safety stops are an important part of any serious dive plan, and should not be overlooked. They help to ensure that divers are safe and that they can enjoy their dive without any unnecessary risks. Taking the time to complete a task.
