Ensuring security in the abyss: Safety systems for deep freediving

Freediving is a sport that requires a high degree of physical and psychological preparation. Divers must train in breathing techniques, buoyancy control, and relaxation skills. However, even with adherence to all training procedures, the risks associated with apnea diving remain high.

Free diving accident can include injuries caused by changes in pressure, loss of consciousness underwater, and even death. To minimize these risks, it is crucial to use the appropriate freediving equipment and to strictly adhere to safety principles.

Safety Principles

Learning to freedive should be done under the guidance of an experienced instructor who will teach exercises, free diving safety fundamentals, and techniques. When going to depth, it is important to monitor not only the time spent underwater but also one’s physical condition. It is necessary to be able to recognize the signs of hypoxia to avoid losing consciousness underwater. Each training session in the water should be accompanied by a certified buddy who can assist in case of an emergency and avoid any free diving risks.

Choosing the Best Equipment for Freediving

When selecting the best freediving gear, attention should be paid to its reliability and functionality. It must be tested and approved for use in freediving and/or spearfishing conditions. Using the right gear and following safety instructions can significantly reduce the likelihood of incidents.

Key Recommendations for Safe Use of Equipment:

  • Use only tested and reliable equipment from reputable manufacturers.
  • Check the overall condition of the freediving buoy, as well as all carabiners, lines, and other gear components.
  • Use only reliable knots for securing ropes.
  • The main line should always be attached to the buoy at one end.
  • Remember that pulley systems (swings) can sometimes fail and fall apart under load, so make an additional knot in the main line before the swings, securing it to the buoy.
  • Before beginning the dive, it is imperative to activate the rope works to ensure the pulley system is engaged and ready for an emergency ascent.
  • The safety system should include a lanyard and a line stopper (not made from a tennis ball), which will stop it one meter before the bottom plate.
  • Always rinse all equipment after use in seawater. Dried salt can over time damage a computer, freediving goggles, mask, fins, wetsuit, and even a freedive buoy.

Underwater accidents and Their Prevention:

Free diving accident can occur for a variety of reasons, including equipment malfunction and human error. One example of negligence is an instructor using a simple knot to secure the bottom weight, which could not withstand dynamic loads, especially in choppy water. Such carelessness can lead to the knot loosening and untying, risking a heavy weight falling on the head of a scuba diver below, creating extreme danger to their health and life. Therefore, the selection and inspection of equipment require thoroughness and attention to every detail.

Another freediving accident involved the use of a tennis ball as a stopper on a descent line. During the descent, the lanyard carabiner hit the soft tennis ball and got stuck on it. This forced the freediver to exert extra effort to free themselves, increasing the risk of panic or hypoxia. Despite a successful ascent, this incident confirmed the importance of using specialized equipment.

Apnea is a fascinating activity that allows humans to explore the depths of the sea on a single breath. However, it is important to remember that safety in freediving must come first. Every diver must understand their responsibility for proper preparation, equipment condition, and adherence to safety procedures. Training with qualified instructors, regular practice, and careful selection of reliable equipment are key elements of safety in freediving.

Adhering to these principles helps minimize risks and maximize enjoyment from diving. It does not forgive haste and inattention, so thorough preparation and adherence to all safety rules must become fundamental habits for anyone who decides to dive into this amazing underwater world.
