Seven tips to help protect you when things go wonky underwater
You may have read somewhere that underwater emergencies are rare. I’m not so sure that rare is the best way to describe them.
While underwater incidents causing bodily harm or death may be infrequent, close encounters with potential disaster are frightenly common. Spend a week or so at a dive resort or on a live-aboard, and you’re guaranteed to hear stories that support this view. “I ran out of air,” “we got separated from the guide and had no idea where the boat was,” “We ended up way deeper than expected,” “My computer went into deco and I had no idea what to do,” “My regulator started to spew bubbles and I panicked… I did not know what to do,” “We skipped our safety stop,” “I felt odd and confused, but managed to hit the inflate button and shot to the surface,” “I signalled the divemaster but he misunderstood me and continued with the dive.”
‘Victims’ of these little brushes with catastrophe fall into three categories. Some give up diving altogether. They get the crap scared out of them and opt for golf, fishing, stamp-collecting. No foul.
Some learn from the experience and avoid the traps that painted them in a corner in the first place, and they become more informed and safer divers.
And some learn nothing. They carry with them the potential to make similar mistakes again and again… sometimes with ruinous consequences.
Here are seven strategies that may help divers enjoy their diving, and avoid becoming a statistic.
- 1) Learn to say no! Too many new divers are fooled into believing that it’s OK to do trust-me dives with a dive guide or divemaster. They may have a good sense that diving once or twice a year does not prepare them for a 40 metre-plus dive (that’s 130 feet or more), in current, with rented gear, but a divemaster, instructor, sales-person talks them into doing it. This is dangerous bullshit. No agency condones this type of practice, but it is common in many dive resorts, and needs to be stamped out.
- 2) Learn your limits and stick to them. There is nothing wrong with pushing yourself to learn and grow your diving experience and comfort zone, but be realistic about your starting point. Being an occasional diver means you start from zero at the beginning of every dive trip. Scuba skills are perishable. Even experienced cave instructors take the time to “brush up their skills” if they have been out of the water for a while.
- Even if you are lucky enough to dive every week, understand that your experience, training and gear limits the types of dives that you can safely undertake. Listen to your inner wimp.
- 3) Learn self-reliance. Too many “rescues” end up in disaster or near disaster for all participants. Get training, learn what kit to wear to help deal with gas emergencies, PRACTICE. Most of all, STOP, THINK, ACT, REASSESS.
- 4) Maintain your kit, and use a checklist when you assemble it and when you inspect it prior to EVERY dive. Equipment problems are the easiest underwater emergencies to avoid. Don’t fall into the trap of believing that something is good enough… if it “ain’t perfect” don’t dive with it.
- 5) Plan your dive… Dive your plan. Understand the risks, make sure everyone is capable of doing the dive, and ensure everyone have the skill and kit to deal with contingencies should they arise.
- 6) Be aware! The best way to deal with a diving emergency is to stop it before it gets out of hand. The vast majority of diving emergencies begin as small inconveniences that cascade rather like dominos falling over. Keep an eye on your buddy(ies), be aware of changes in the conditions, monitor yourself. The best blanket advice is to take things slowly.
- 7) Have an escape strategy. When something goes pear-shaped, the top priority is to make sure everyone has something to breathe… next is to get yourself and your mates as far away from the spinning fans as possible. Cave divers talk about always having a continuous guideline to the surface. Sport divers can take a lesson from that: Always know the location of a safe, protected exit… in other words, someplace where you can surface and be found or find your way to your entry point.
