The history of the safety stop stands as a testament to the evolving understanding and prioritization of diver safety.
From its inception in the 1970s with the establishment of recommended ascent rates, to its integration into diving manuals and the introduction of the Recreational Dive Planner, safety stops have gained recognition and acceptance over the years.
Supported by research on ascent rates and bubble formation, safety stops have become a fundamental aspect of diving, reinforced by dive computers.
This article explores the historical milestones and the influential role of military divers and education in shaping the importance of safety stops in the diving community.
- Safety stops have evolved over time, with the US Navy establishing an ascent rate in the 1970s and PADI introducing safety stops to a wider audience in 1988.
- Research and studies, such as Andrew Pilmanis' 1974 study and Donna Uguccioni's 1994 masters thesis, have contributed to the acceptance of safety stops among divers.
- Safety stops provide various benefits, including off-gassing nitrogen, preventing bubble formation, reducing the risk of decompression sickness, promoting awareness during ascent, and enhancing overall dive safety.
- Safety stops are now widely recognized as a fundamental aspect of diving, with dive computers reminding divers to perform them and the practice of safety stops improving dive safety.
Evolution of Safety Stops
The evolution of safety stops in recreational diving has been marked by significant milestones and advancements.
In the 1970s, the US Navy established an ascent rate of 18 meters/60 feet per minute.
In 1974, Andrew Pilmanis conducted a study on ascent rates and bubble formation in divers. This research laid the foundation for understanding the importance of safety stops.
By 1984, the PADI Open Water Manual recommended safety stops, and in 1988, the Recreational Dive Planner introduced safety stops to a wider audience.
PADI's S.A.F.E. Diver campaign further helped educate divers on the benefits of safety stops.
Increasing awareness and adoption of safety stops have been observed, with dive computers reminding divers to perform them.
The understanding of how safety stops help off-gas nitrogen absorbed while diving and prevent bubble formation has led to reduced risks of decompression sickness.
Research and Acceptance of Safety Stops
Research and acceptance of safety stops in recreational diving have been steadily increasing since the 1970s. This can be attributed to several factors:
- Andrew Pilmanis' study in 1974: Pilmanis conducted research on ascent rates and bubble formation in divers, highlighting the importance of safety stops in preventing decompression sickness.
- Donna Uguccioni's masters thesis in 1994: Uguccioni expanded on Pilmanis' work, further emphasizing the benefits of safety stops in reducing bubble formation.
- Doppler tests: These tests showed that divers who practiced safety stops had less bubble formation, providing scientific evidence of their effectiveness.
- Gradual acceptance: Over time, divers have become more aware of the advantages of safety stops, and the popularity of dive computers has also contributed to their acceptance.
Benefits of Safety Stops
The practice of safety stops in recreational diving offers numerous benefits to divers, ensuring the gradual release of nitrogen absorbed during the dive and reducing the risk of decompression sickness. Safety stops help off-gas nitrogen that has been absorbed while diving, allowing the body to release nitrogen slowly and prevent bubble formation. This gradual release of nitrogen helps to prevent decompression sickness, a potentially serious condition caused by the formation of nitrogen bubbles in the body. Safety stops also promote awareness of potential obstacles during ascent, enhancing overall dive safety and well-being. Dive computers often remind divers to perform safety stops, further improving dive safety. Overall, safety stops are widely recognized as a fundamental aspect of diving, preventing decompression sickness and promoting dive safety and well-being.

|Helps off-gas nitrogen absorbed while diving|
|Allows the body to release nitrogen slowly|
|Reduces the risk of decompression sickness|
|Promotes awareness of potential obstacles|
|Enhances overall dive safety and well-being|
Current Status of Safety Stops
Currently, safety stops are widely recognized as a fundamental aspect of diving and are considered beneficial for all divers.
Here is the current status of safety stops:
- Dive computer reminders: With the technological advancements in dive computers, divers now receive reminders to perform safety stops during their ascent. These reminders help ensure that divers adhere to safe diving practices and minimize the risk of decompression sickness.
- Improved dive safety: The practice of safety stops has significantly contributed to improved dive safety. By allowing the body to release nitrogen slowly and prevent bubble formation, safety stops help reduce the risk of decompression sickness. Additionally, safety stops promote awareness of potential obstacles during the ascent, enhancing overall dive safety and well-being.
- Widely recognized: Safety stops have gained widespread recognition in the diving community. They are now considered an essential part of dive planning and execution, with divers of all levels and experience incorporating them into their diving routines.
- Fundamental aspect of diving: Safety stops have become an integral component of modern diving practices. They are no longer seen as optional but are instead seen as a necessary precaution for divers to ensure their safety and well-being.
Influence of Military Divers and Education
Military divers have played a significant role in shaping the practices of recreational diving, particularly in relation to the influence of education and safety measures. Through their combat diving experience and military training, they have brought valuable knowledge and techniques to the recreational diving community. Educational campaigns initiated by military organizations have helped raise awareness about diving regulations and safety practices. One notable example is PADI's S.A.F.E. Diver campaign, which emphasized the importance of safety stops and educated new divers on the Slowly Ascend From Every Dive acronym. This campaign, along with the continued emphasis on safety stops, has contributed to the establishment of recreational diving standards and the integration of safety measures into dive practices. The influence of military divers and their commitment to safety has greatly enhanced the overall safety and well-being of recreational divers.

Frequently Asked Questions
How Do Safety Stops Differ for Technical Divers Compared to Recreational Divers?
Technical divers have different safety stop requirements compared to recreational divers. Technical divers undergo specialized training and are equipped with advanced dive computers and gas mixtures, allowing for longer and deeper dives that require more complex decompression strategies.
Are There Any Specific Guidelines for Performing a Safety Stop at Different Depths?
There are specific guidelines for performing a safety stop at different depths in order to ensure a proper ascent rate and reduce the risk of decompression sickness. These guidelines emphasize the importance of gradual ascent and off-gassing of nitrogen.
Can Safety Stops Be Performed During Every Dive or Are There Certain Situations Where They Are Not Necessary?
Safety stops should be performed during every dive as they provide numerous benefits, including off-gassing nitrogen, preventing bubble formation, reducing the risk of decompression sickness, and enhancing overall dive safety. Proper ascent rates are of utmost importance in ensuring the effectiveness of safety stops.
Are There Any Potential Risks or Disadvantages Associated With Safety Stops?
