【自潛安全】潛立方自潛安全守則,在淡水潛水一定要知道的觀念!

除了在海洋環境,台灣、韓國、義大利、杜拜…等世界各地,皆有很棒的「室內潛水池」可以進行潛水訓練,厲害的造景供大家拍攝,環境單純、無風無流、不會暈浪,是不是很棒!在淡水潛水,與海水有何不同?要注意哪些事情呢?



❶ 浮力在淡水與海水不同

海水的浮力會比較強,因此在海洋環境上課時,要更有效率的動作才能下得去。

在淡水中浮力較弱,一開始來到潛立方,會發現「非常容易下潛」,甚至可以在很淺的深度就體驗到緩緩的「free fall 自由落體」。此時很容易忘記要把動作確實做好,用「太緩慢」的速度下降。上升時,也因為浮力比較弱,用同樣輕鬆踢或是技巧/效率不佳的動作上升,也會太緩慢,造成潛水時間過長,進而增加低氧的風險!

👌練習中,因應浮力變化,維持適當動作效率,正常的雙蹼潛水速度,應為0.8-1m/s 。12米的初階課程考核,整趟潛水應在30秒內完成較佳。

👌在淡水的環境中,更加保守的推進深度,避免很難上升的風險。有必要時也要改變上升方式(比如:改成攀繩上升)。

 

❷ 注意保溫保暖

在潛立方為了美美的或是帥氣的拍攝影片照片,大多數人會選擇著泳衣下水。潛立方的水有加溫,剛開始下水感覺還行,不過泡久了,有可能還是會感覺冷。身體在冷、發抖的狀態下,難以放鬆,此時又因為場次時間快結束了,可能會想「再撐一下」就好,下潛的過程可能會經歷更強的呼吸渴望、抽動、緊繃僵硬,使低氧風險增加。

如果發現自己比較容易冷,還是要注意讓自己上岸保暖、換穿防寒衣~

 

❸ 落實潛伴制度,熟悉救援動作

最基本的潛伴制度還是要強調一下!

下水前了解、認識潛伴的程度、狀況,注重彼此的安全,如同自身也希望被好好戒護一樣。時時複習救援練習,而不是只有上課考完試就忘記。當然希望大家每次都安全下去又回來,但是仍要讓自己準備在緊急時派上用場。

👌在潛立方常會進行「拍攝」,非常建議拍攝者、潛水員都有各自的戒護/潛伴。畢竟兩人一起下去,都在進行閉氣潛水,潛水時間一樣長,有額外的戒護,才能確保大家安全。

Freediving Safety in Fresh Water

❶ Buoyancy is different in fresh water and salty water

The buoyancy in salty water is stronger, so when taking lessons in a marine environment, more efficient technique is required to be able to go down.

In fresh water, buoyancy is weaker. When first coming to Dive Cube, you will find it very easy to swim down, and you can even experience a slow “free fall” at a shallow depth.

At this time, it is easy to forget to perform the fin kickes correctly and descend too slowly. When ascending, due to the weaker buoyancy, using the same relaxed kicking or poor technique/efficiency will also make the ascent too slow, causing the dive time to be too long and increasing the risk of hypoxia!

👌 During practice, adjust your finning to buoyancy changes and maintain appropriate efficiency. The normal speed of finning with bi-fins should be 0.8-1m/s. For the 12-meter AIDA 2 course assessment, completing the entire dive within 30 seconds is preferable.

👌 In fresh water environments, be more conservative in progressing your depth to avoid difficulty in ascending. Change the ascent method if necessary (e.g., FIM to ascend).

 

❷ Keep yourself warm

At Dive Cube, most people choose to dive in swimsuits for better looking photos and videos. The water at Dive Cube is heated, and it would feel fine at first, but if you stay in the water for too long, you may still feel cold. When the body is cold and shivering, it is difficult to relax, and as the session time is about to end, you may want to “endure a bit,” which can lead to stronger urge to breathe, twitching, tension, and stiffness, increasing the risk of hypoxia.

If you find yourself easily getting cold, make sure to keep yourself warm by resting on land or putting on wetsuits.

 

❸ Implement the buddy system and be familiar with rescue

Understand and get to know your buddy’s technique level and condition before diving. Focus on each other’s safety, just as you would want to be well secured.

Regularly review diving rescue skills. Of course, we hope that everyone dives down and return safely. However, still prepare yourself to be alert and react swiftly in emergencies.

👌 At Dive Cube, people usually do filming, and it is highly recommended that both the cameraperson and the diver have their own safety guard/buddies. After all, when two people go down together, both performing breath-hold, having additional protection ensures everyone’s safety.
