Here at Pinpoint Electronics, we specialise in safety equipment and devices for those at sea. And, this includes both leisure and commercial divers. As you dive deep underwater, it’s imperative that you have the experience, skills and equipment on hand to keep you safe. The fatality rate for recreational divers is 1.8 per million and to avoid getting in potentially fatal situations, it’s important that you understand the key rules and safety steps to take. Read on to learn more.
- 1. Always, always, always check your equipment
When you’re underwater, your equipment is more important than in most other settings. Your very survival relies on the quality and performance of the tools you have on your person. Never bypass this step – checking your equipment and that of your buddy is vital. In accidentally caused by equipment, the vast majority occur because the user doesn’t know how to use it properly. Make sure you understand the safety process and be prepared from the very beginning.
- 2. Plan your dive in detail
If you’re working with a professional diving company, they should provide a detailed plan for your dive. And, if you’re going off on your own, it’s still imperative that you clearly plan out your dive. Make sure you understand how much oxygen you need, what pressures your equipment may be under and who will be with you.
- 3. Never hold your breath
As you descend through the water, the air in your lungs contracts. When you ascend at the end of your dive, it expands. This is known as Boyle’s law. If you hold your breath while diving, this additional oxygen can cause the lung walls to rupture, resulting in pulmonary barotrauma. Always breath!
- 4. Dive in safe places
Part of planning your dive is understanding that the location you’ve chosen is safe. Make sure you feel comfortable diving in your location or cancel the session if you are concerned about safety.
- 5. Rule of quarters
The rule of quarters ensures you have the right amount of oxygen available for the duration of your dive. It states that divers should use 2/4 of air supply for the journey outwards and 1/4 for the journey back and 1/4 as a safety reserve. Follow this religiously.
- 6. Maintain your fitness
Diving is physically exhaustive and you need to have a good fitness level to enjoy the experience. Take into account changing systems such as strong currents and the weight of additional gear when planning your dive.
- 7. Practise your safety skills
There are certain skills that have the potential to save your life when diving at sea. Things such as understanding how to change your buddy’s air source or disconnect the pressure inflator hose.
- 8. Use the buddy system
You should always uphold the buddy system – regardless of whether you’re a competent and experienced diver. Situations underwater are unpredictable and there’s no knowing what could happen. Stay close to your buddy at all times.
- 9. Positive buoyancy
A significant percentage of fatalities during driving are caused by the conditions of the surface water. Positive buoyancy is the act of floating up to the surface – it helps to combat fatigue, preserve energy and reduce the risk of drowning.
