You don’t leave reels in the cave for days at a time, much to the frustration of other teams.There is less temptation to make visual jumps or gaps in order to save a “clean up dive” in which you retrieve a reel later on.(Knowing what the cave is supposed to look like on the way out can save your life.) You get to see what every passageway looks like, both entering and exiting.You actually experience more of the cave on each dive.Linear dives are unquestionably safer and offer several benefits, including: That is, you come out the same way you go in. One of the best ways to avoid getting lost is not making circuits and traverses. Failure to follow established procedures at intersectionsĪvoid these, you help avoid getting lost.The problem is that getting lost easily results in divers running out of gas before finding their way out of the cave.ĭivers can get lost in caves for any of a variety of reasons. Strictly speaking, getting lost isn’t fatal in and of itself. These are the areas where you should focus your greatest attention. With that in mind, here are the top three reasons certified cave divers die in caves. To the best of our knowledge, there has yet to be an instance where one diver emerged from a cave saying, “I could have saved him, but the dumb bastard just couldn’t share gas.” Thus, the more valid line of reasoning is not so much focusing on the ability to share gas but rather on avoiding the need to do so. When divers are with a buddy and one runs out of air, they almost always are able to share gas successfully…until the donor runs our of gas as well.

The ability to share air is of little value if divers are by themselves.

But here is where that line of reasoning falls short.

It would seem to make sense, then, that gas sharing is a vital skill which will help prevent this.

Most cave diving fatalities involve divers running out of air.

One thing we have noticed, however, is that instructors sometimes focus their attention on problems that are far more theoretical than actual.

More divers go home at the end of the day.

The principle underlying Accident Analysis remains valid. Once we begin dealing with certified cave divers, the landscape changes. Here is what we all too often don’t teach our cave diving students: The Rule of Accident Analysis helps explain why untrained divers dive in caves. We all know that Accident Analysis forms the foundation of modern cave diver training…right? Follow the rules of Training, Guideline, Air, Depth and Lights and you won’t fall victim to the five things that most often cause open-water divers to perish in caves. However, when these events happen in combination, things can get very bad, very fast. This is when no single event in the cascade is fatal in and of itself. Nearly all are avoidable.Īs often as not, certified cave diver fatalities are the result of and event cascade. There are, of course, several such reasons.

This article is the result of a series of discussions I’ve been having with Lamar regarding the real reasons certified cave divers fail to come out of caves alive. Even Lamar does not have an exact number, but says it is more than 30. Although no one is really keeping count (and no one wants to), it’s likely that Lamar has worked more certified cave diver body recoveries than anyone on the planet.
