Risk Management in a Climbing Environment – Part I

Climb if you will, but remember that courage and strength are naught without prudence, and that a momentary negligence may destroy the happiness of a lifetime. Do nothing in haste; look well to each step; and from the beginning think what may be the end. – Edward Whymper

Let me preface this by stating that while I may be charged with managing and communicating risk in my professional life I am certainly no expert in Risk Management and these thoughts should be considered just that, my thoughts.  However, my observation is that we’re all confronted with some level of risk on a daily basis and readily go about managing it without an expensive degree in the wide-ranging field of study.  Below you will find my informal attempt to define risk and then in Part II apply a reasonable risk management framework to a climbing environment.  The goal of this entry is to put risk and risk management into perspective for myself in the context of climbing and create a decision-making system that will facilitate safe passage in the mountains that I can continue to develop.

As recreational and professional climbers it is not unreasonable to think we can self-study and learn to apply a framework to risk management, even at a basic level, that can advance a safer and more enjoyable experience in the mountains or at the local crag.

Other than transferring the main responsibility of risk management to someone else (a professional guide for example) there is no credible substitute for experience and education in terms of effectively identifying risks in a climbing environment.  My personal philosophy is that one should never rely on someone else to entirely manage risk for us.  We should constantly be scrutinizing situations and decision-making if for no other reason than to learn from the experience.

On Risk

So what is risk, exactly?  The ISO/IEC defines risk as the combination of (a) the probability of an event occurring, and (b) the consequences of that event.

Therefore risk is an equation, something to be judged carefully and that includes multiple parts.  To add a twist, in climbing environments, these variables of probability and consequence are often fluid.  Probability can vary based on changing weather, time of day, and terrain (e.g., glaciers), and consequences can be different depending on our actions.  A simple example of how we can influence both aspects of risk would be (a) an individual reducing the probability of an avalanche occurrence by avoiding the terrain altogether and (b) reducing the potential consequences by wearing a helmet and beacon, and carrying a probe and shovel.  You may conclude that certain safety systems such as wearing a helmet and beacon reduce the potential consequences but have no affect on the probability.

This ability to influence risk is why I personally believe continuing professional development (medical, avalanche, technical systems, etc.) and continuing my own self-education through critical self-analysis and study is an integral part of risk management.  If we perceive a threat as lower than it actually is through our inexperience or lack of knowledge then we expose ourselves and our partners or clients to unnecessary risk.  Conversely, if we perceive a threat as greater than it actually is we have the potential to sacrifice efficiency in moving toward our objective. Before we can treat risk, we need to be able to identify it.

Consider that while the probability of an avalanche may be low based on a personal assessment, the event can often have life and death consequences.  Therefore, in this instance, the identified risk would be the potential for an avalanche resulting in a consequence of death or serious injury and decisions would need to be made accordingly.  This is risk and it is constantly variable.  In the context of climbing, you may now appraise an avalanche without a human actor as not a risk at all, but rather a naturally occurring event.  Consider that if we don’t have a complete and accurate valuation of both probability and consequence, we don’t in fact comprehend the risk in its entirety. Any decision-making  involves a bit of luck.

Travel with and learn from someone who can identify the objective hazards and assess risks. Never rely on a system you don’t fully understand.  If you have no awareness of how snow can be transported in the hills and then decide to climb accepting  a ‘Moderate Avy Danger’ rating posted at 0600 you may still end up wandering onto a wind loaded slab triggering a slide that rips you off the climb.  Before a valid risk decision can be made and acted upon, individuals need to be able to competently identify and describe the risks inherent in the terrain in which they travel and are potentially exposing themselves and others to.

Also, be sure to assess the net total of a consequence.  After all things have been considered, if an event occurs, what will be the potential result?  We need to consider not just broken bones and the misery of dragging ourselves four kilometers back to a car, but also how the consequences will affect our families, jobs, and whatever else would be affected by the occurrence.

In conclusion, risk is a combination of probability and consequence that doesn’t exist without a human actor.  Think about how an avalanche has no real consequence without a human being in its path.  To begin formulating and defining risks start asking yourself ‘What could go wrong?’ and ‘What could the consequences be?’ This will give you a basic understanding of risk.

The real challenge beyond identifying and defining risk becomes risk management.  In Part II I’ll begin to cover risk management which includes topics such as: risk assessment, evaluation, decision-making, risk treatment, and risk monitoring.

Carabiner Brake Tutorial

The sun is setting on an already long and imperfect day in the alpine when you accidentally drop the plaquette device you were planning to begin the next dozen rappels with. What now? How do you get down? Walking off is inadvisable due to the exposed terrain combined with nasty weather moving in from the northwest, so you’ll need to improvise something quick from the kit that exists between you and your climbing partner.

As climbers, the most representative and common item we carry aside from a rope is the carabiner. On an ordinary climb there is often more than 25 ‘biners between two partners – sometimes far more. A popular way to rappel in the ‘60s was to use the carabiner brake, and it’s still expected that AMGA Alpine Guides know this technique. Below is a quick tutorial I put together to demonstrate the steps to setup this Cadillac smooth rappel technique. Marc Chauvin demonstrated this technique during a 2-day climbing self-rescue course I participated in recently and the AMC includes it as a part of their rock program each spring.

Figure 1

Step 1. Start with a locking carabiner clipped (and locked) to your harness. Alternatively, in the unlikely circumstance that you don’t have a locker, you can use two opposite and opposed non-locking carabiners. Think of what needs to happen in the more common ATC/Reverso rappel setup. Essentially, you need to secure the breaking device and rope to your harness. This first step gives you that security so it needs to be foolproof.

Figure 2

Step 2. Take any regular non-locking carbiner, whether it’s oval-shaped, d-shaped, wire gate or bent gate and clip it to the locker as illustrated in Figure 2. Try to use similar carabiners if you can, if for no other reason than the aesthetic.

Figure 3

Step 3. In this step you’ll take another non-locking carabiner and perform the same basic action as in step 2 with the exception that this carabiner gate needs to be opposite and opposed to the first gate as illustrated in Figure 3. The gates should open in a ‘X’ pattern making it more difficult for the rope to unclip. This is the standard way climbers substitute for a locking carabiner when one is unavailable.

Figure 4

Step 4. Picture again your ATC or Reverso. This time focus on the slots that accept a bight of rope and keep a bend in that same section. In the previous step we used two carabiners to create that same slot. The brake is now secured to our harness and has a slot that performs the same function as the slot on a modern plaquette. In this step you simply take a bight (or two) of rope and feed it through the carabiners. Obviously it’s different for single and double rope rappels. Do we really need to go there?

Figure 5

Step 5. Now it’s time to create the friction that facilitates a controlled descent. Take two non-locking carabiners and clip the strands as illustrated in the Figure 5. The spines of these carabiners should be on the side that the rope runs over. The intent is to create friction. In an ATC/Reverso setup we normally use one locking carabiner to capture the rope we’ve fed through the device slots and also secure them to the belay loop on our harness. These two carabiners add the friction by capturing the rope and also work with the previously added carabiners to secure the rope to our harness.

Figure 6

Step 6. Slide the two carabiners we added in step 5 down into the position illustrated in Figure 6. Both strands should run smoothly over the spines of these carabiners and provide sufficient friction for a single person rappel.

Figure 7

Step 7. Optional – If you find yourself in a situation where you need to perform a tandem rappel or just simply require more friction you can add more surface area for the rope to run against by adding a locking carabiner as illustrated in Figure 7.
