Lowering a climbing partner is among the most common situations leading to injuries and rescues reported in Accidents in North American Mountaineering, whether it’s lowering a climber after she tops out on a sport route or a partner in difficulty on a multi-pitch climb. In this year’s (2013) Know the Ropes section, we will look at common causes of accidents related to lowering, and provide some best practices for preventing them.

Why is it so important to have a good understanding of lowering skills and techniques? Think about how often we lower a climbing partner. We all do it frequently in single-pitch climbing, whether top-roping, gym climbing, or lowering the leader after he finishes a sport, ice, or traditional route. We tend to emphasize the belaying aspect of these activities, when in fact data shows there is substantial risk of an accident occurring during the lowering phase. Think about it in these terms: If all goes well during the climb, we don’t even use the safety systems in place. They are simply there “just in case” the climber falls. Once the lowering process starts, however, every component in the system engages and is critical to the safety of the climber. Then, of course, there are unlimited scenarios in multi-pitch climbing—whether rock, alpine, or ice—where lowering can be an effective tool to increase the speed of the party or to help a frightened or incapacitated partner.

Based on the incidents reported in Accidents over the past decade, the four most common causes of lowering accidents are: a rope that’s too short, miscommunication, an inadequate belay, and anchor failure. We’ll look at each of these issues and provide basic and advanced skills and techniques to address some of these common problems. Regardless of whether we are lowering from below or above, or are in single or multi-pitch terrain, many of the same skills and techniques are required.

Rope Too Short

More than half of all lowering accidents reported in Accidents in the past decade occurred when the rope end shot through a belay device and the climber fell uncontrollably. It is very easy to misjudge the length of your rope and/or the height of the anchor in vertical terrain. However, most of these unfortunate accidents could have been prevented simply by closing the system. This will make it impossible for the rope to unintentionally pass through the belay device.

*FIGURE 1: The triple overhand knot is an excellent stopper knot for the end of a belay rope or rappel ropes.*

In a typical single-pitch climbing scenario, where the pitch length is less than half the available rope, the ground closes the system by default, meaning your partner is going to make it back to the ground before the belayer gets to the end of the rope, so closing the system is unnecessary. The problem comes when the anchor is near or above the midpoint of the typical rope. This is increasingly common as new routes are established with anchors above 30 meters (half the typical modern rope length). For some climbs, a 70-meter rope is now mandatory to lower safely. Before trying an unfamiliar single-pitch route, read the guidebook carefully, ask nearby climbers, and/or research the climb online to be sure it doesn’t require a 70-meter rope to descend safely. When in doubt, bring a longer rope or trail a second rope.

Another scenario frequently leading to single-pitch lowering accidents is a climb where the difficulties begin after scrambling five or ten feet to a high starting ledge. The anchors at the top of such routes may be set in such a way that there is plenty of rope to lower the climber back to the ledge, but not all the way to the ground. Or the belayer may need to be positioned on the starting ledge in order to have enough rope to lower the climber safely. Again, do your homework, ask other climbers, and always watch the end of the rope as you’re lowering a partner.

If there is any doubt about the length of the rope being adequate to lower a climber safely, tie a bulky stopper knot in the free end so it cannot slip through the belay device. (The triple overhand knot is a good choice; see Figure 1.) Better yet, the belayer can tie into the free end, thus closing the system.

As you belay a lead climber on a long pitch, keep a close eye out for the middle mark so you’re aware of whether there is enough rope to lower the climber. Once the middle of the rope passes through your belay device, you and the climber need to be on high alert. Rope stretch may provide a little extra room for the climber to be safely lowered to the ground, but in such cases the system should always be closed as discussed above. When in doubt, the climber should call for another rope and rappel with two ropes.

As the climber lowers, it’s natural to keep an eye on her, but as the belayer you should also be watching the pile of free rope on the ground. Once there is less than 10 or 15 feet remaining, make a contingency plan for safely completing the lower. For example, will the climber have to stop on a ledge and downclimb? Will you need to move closer to the start of the route? Never let the last bit of rope slip through the device if the climber is still lowering, even if she is only a foot or two off the ground—the sudden release of tension can lead to a free fall and tumble.

When lowering in the multi-pitch environment, the belay system must be consciously closed by having the non-load end of the rope tied to the belayer, the anchor, or something else to prevent it from passing through the belay device. In a multi-pitch rappelling scenario we close the system by knotting the ends of the rappel ropes, making it impossible to rappel off the ends.

Miscommunication

The three key problems with communication between climber and belayer are 1) environmental, 2) unclear understanding of command language, and 3) unclear understanding of the intentions of the belayer and climber.

Environmental problems include the climber and belayer being unable to see each other because of the configuration of the route and/or the distance between the two; weather conditions such as wind, snow, or rain; and extraneous noises, such as a river, traffic, or other climbers shouting commands or chatting nearby.

In popular climbing areas with many parties on routes near each other, climbers sometimes mistake a command from a nearby party as coming from their partner. It’s always a good practice to use each other’s names with key commands: “Off belay, Fred!” or “Take, Jane!” When one climber is at the top of a single-pitch climb and rigging the anchor for a lower-off, top-rope, or rappel, it can sometimes be helpful for the belayer to step back temporarily so he can see his partner at the anchor and improve communication. When the climber is ready to lower, the belayer can move back to the base of the climb to be ideally positioned for the lower.

Especially with a new or unfamiliar partner, it’s essential to agree on the terms you’ll be using to communicate when one climber reaches the anchor. What do you mean by “take” or “off” or “got me?” Avoid vague language like “I’m good” or “OK.” Agree on simple, clear terms and use them consistently. One common misunderstanding seems to be the result of the similar sounds of “slack” and “take.” When top-roping, consider using the traditional term “up rope” instead of “take” for more tension in the rope, as the former won’t be confused with “slack.”

Before starting up any single-pitch climb, it’s critical that belayer and climber each understand what the other person will do when the climber reaches the anchor: Will the climber lower off, and if so what language will she use to communicate with the belayer? Or, will she clip directly to the anchor, go off belay, and rappel down the route? Many accidents have resulted when the belayer assumed the climber was going to rappel instead of lower, or the belayer forgot that the climber planned to lower, or he misunderstood a command (“off” or “safe” or “I’m in direct”) as an intention to rappel. Before taking the climber off belay, the belayer must be certain that this is the climber’s intention. If you have agreed that the climber will rappel, wait for the climber to yell “off belay,” and then respond “belay off,” and only then remove the rope from your device.

When you reach the anchor at the top of a climb, don’t just clip in, shout “take,” and lean back. Make sure to hear a response from the belayer indicating that he has you on belay and is ready to lower. If you can’t see the belayer, sometimes it is possible to extend your anchor connection or lower yourself a little, holding onto the “up” rope, until you can get into position to make visual contact with the belayer and assure you’re still on belay.

A consideration when lowering someone from above is that the belayer and climber become farther apart during the lowering process, and this may compromise communication. To mitigate this potential problem, I like to position myself where I can see, and hopefully hear, the climber being lowered from start to finish. In some terrain this requires extending the anchor’s master point.

Belay System Errors

A common cause of lowering accidents is belayer errors, especially when the belayer is inexperienced, inattentive, or unfamiliar with the operation of a particular type of device. Make sure your belayer—or any belayer you observe— knows what he’s doing and pays attention until his climber is safely back on the ground or at an anchor. Don’t accept or ignore shoddy belaying!

On single-pitch routes, two things that may cause problems are belayers positioned too far back from the base of the climb—and thus getting pulled off balance and possibly losing control when the climber weights the rope—as well as using an unfamiliar device. Switching between tube-style devices, such as an ATC, and assisted-braking devices like the Grigri can cause inexperienced belayers to mishandle the device. Beware of loaning your device to a belayer unless you are confident that he is well-trained in its use.

What is the appropriate lowering brake for lowering your partner? It’s one that provides adequate friction to control their descent over very specific terrain. In some alpine terrain situations, the redirected hip belay may be totally sufficient for a short, moderate-angle step with high friction. Conversely, lowering directly off an equalized multi-point anchor with a backup may be required in steeper terrain (see Figure 2).

FIGURE 2: Lowering a partner from above with a redirect and backup. A) Belay/ rappel device with locking carabiner clipped to master point. B) Redirect through carabiner clipped to anchor. C) Prusik knot clipped to belay loop as backup—useful for heavier partners or wet or icy ropes.
*FIGURE 3: Increasing friction for a lower with a thin-diameter or wet or icy rope, using a Munter hitch on a locking carabiner clipped to the anchor above the belay/rappel device.*

In some cases, the most important belay issue may be anchoring the belayer against a violent upward pull in the event of a leader fall or a falling or lowering top-rope climber who is much heavier. In this situation I like to be tied directly into the climbing rope and use a clove hitch to attach myself to a bottom anchor. This way the length is adjustable so I can be exactly where I want with no slack in the system, and the rope provides shock adsorption if the system becomes loaded.

Most people tend to underestimate how much friction is needed to lower their partner in a safe and controlled manner. How do we gain the experience required to be safe? Through time and practice in varied terrain. Be conservative at first and anchor the belayer, increase friction, use a backup—or all three—until the belayer has confidence in judging how much friction is needed. It’s easy to back up a new climber’s belay by holding the brake strand a couple of feet beyond the belayer and feeding the necessary slack. This allows you to closely monitor the belay and provide additional braking if the climber starts going too fast or the belayer starts losing control.

Do you have experience lowering with wet or icy ropes? Do you have experience lowering with modern small-diameter ropes? If not, then I would recommend increasing friction when lowering someone from above (see Figure 3), as well as backing up the lower with a prusik, until you gain adequate experience. Bottom line: If the consequence of losing control of the brake strand is bad, add friction and back it up.

Prior to committing to any lower, consider some “what ifs.” For example, what if something happens when I’m lowering my partner and I need to be mobile? How easy is it for me to escape the system? What if I need to transfer this lower to a raise? Does this system allow me to make this transition easily?

Anchoring Issues

There is much to consider when constructing an anchor, but the bottom line is that it absolutely must not fail, period. (The Know the Ropes article in the 2012 Accidents is a great reference on constructing anchors.) What are some of my concerns when choosing a possible anchor? 1) Will I be using this anchor for climbing and lowering or rappelling? 2) With the resources available, can I construct an adequate anchor in a given spot? 3) How will the rope run once lowering starts? 4) Will the belayer and climber being lowered have visual and/ or audio communication for the duration of the lower?

I have long used the ERNEST acronym as guidance when constructing an anchor. E = Are all pieces in the anchor equalized and sharing the load? R= Is there redundancy in the anchor, meaning that if one piece fails other pieces will take the load? NE= If one piece does fail and the other pieces take the load, will this be done with no extension or shock loading of the remaining anchor? S= Is the anchor material (tree, rock, ice) and/or protection solid and strong? T= Can this anchor be constructed in a timely manner? Just remember, ERNEST should be used as guidance, not a checklist—adjust as necessary. Once an anchor has been established, we must decide how to connect the rope to the anchor.

Sometimes a route may be too overhanging or traverse too much to clean by rappel. In such cases, it may be necessary to clip into the belay rope while lowering (a.k.a. “tram in”) to stay close to the wall and remove each piece. Be sure to communicate each step clearly with your belayer, and never unclip from the belay rope when you are away from the wall (as shown here), because you will plunge straight downward when the tension is released, possibly hitting the ground. Instead, only unclip from the belay rope when you’re clipped into a bolt or the belay rope is taut against the cliff face. Make sure to do this in a place where you won’t hit a tree or the ground when you swing off. PC: Andrew Burr

All top-roping should always be done through the climber’s removable gear, such as carabiners attached to quickdraws, runners, or a cordelette, and not through the fixed hardware of an existing anchor system. The fixed anchors should only be used for rappelling, where the ropes will be pulled without load. A dirty rope running through the anchor system under load causes unnecessary wear at fixed anchors. In fact, at some sandstone climbing destinations where sand easily works into the weave of the rope, locals are reporting 50 percent wear of steel quick- links in a couple of climbing seasons. So whether you are top-roping or topping out on a sport climb, be responsible and climb or lower on your own removable gear. Whenever possible, the last person to climb should rappel rather than lower off once he is finished with the route.

Before leading a sport climb, decide what extra gear will be needed for the anchor. To set up for lowering and top-roping, I like to carry two quickdraws designated for the anchor, one of them equipped with two locking carabiners. Before following a sport climb, decide what extra gear will be necessary to clean the top anchor. I girth-hitch two 24-inch nylon slings to my harness and add two locking carabiners. When I get to the anchor, I clip a locking carabiner to each rappel ring. Now I can thread the rope through the fixed anchor and rappel. There are a variety of techniques for accomplishing this. Regardless of the one you learn, I recommend practicing while on the ground and using the same system every time you clean the anchor.

One subtle but very important difference between rappelling and lowering is that in rappelling the rappel device is moving over a stationary rope, because the person rappelling is simply sliding down the rope. In lowering, the rope is the object in motion and is moving through a stationary belay device. This means the rope is moving over terrain that may have loose rock and/or sharp edges. In general a taut rope over a sharp edge is not a good idea, and one that is moving over sharp edges is just asking for trouble. Before lowering, take extra care to position the rope so it avoids any edges or loose blocks. And, finally, never lower with the rope running directly through an anchor sling—the hot friction of nylon on nylon will quickly melt through the sling, with disastrous consequences.

Be Prepared!

As climbers we all need to take ownership in the ability to problem-solve and be self-sufficient at the crag and in the mountains. This starts by critically thinking about what gear we carry on a given objective. For example, I choose to use an assisted-braking device (such as the Petzl Grigri) for top-roping, sport routes, and gym climbing because of the added security and comfort for holding and lowering a climber. In the mountains and on traditionally protected climbs I use an auto-blocking device (such as the Black Diamond ATC Guide or Petzl Reverso) because it is lighter, much more multifunctional, and it allows the rope to slip a bit when catching a fall, helping to reduce impact forces. Another example: I use accessory cord to tie my chalk bag around my waist, so I always have a cord I can easily convert into a prusik if I need to back up a lower or rappel.

In addition to my harness, protection, quickdraws, and shoulder-length slings, here’s what I typically carry on most multi-pitch climbs, giving me the tools to deal with most situations that might arise:

Small knife or multi-tool
Auto-blocking belay/rappel device with 2 locking carabiners
2–3 extra locking carabiners
5–7mm* cord to tie on chalk bag, doubling as a prusik cord
5–7mm*, 18-foot cordelette with a non-locking carabiner
Two 48” slings, each with a non-locking carabiner
1 extra 5–7mm*, 18-foot cordelette with rappel rings (for multi-pitch
alpine routes)
24” nylon sling for racking gear
* As a general rule, a cord or cordelette needs to be 2–3mm smaller than the climbing rope in order to provide adequate friction for a prusik.

FIGURE 4: When using an auto-blocking belay device in guide mode to belay a second climber, it may be necessary to “release” the locked device when it’s under load, in order to lower the second so he can reach a ledge or retry a move. Thread a thin sling through the small hole opposite the clip-in hole on the device, redirect it through the anchor, and clip it to your harness so you can use body weight to release the device. For additional control of the lower, always redirect the brake strand through the anchor. As a back-up, tie a friction hitch onto the brake strand and clip it to your harness. PC: Sterling Snyder
*FIGURE 5: The Munter hitch can be used instead of a device to belay or lower a climber. It’s preferable to orient the hitch with the load strand on the gate side of the carabiner.*

Since we are somewhat limited in the amount of gear we carry on a given objective, it makes sense to maximize our understanding of the gear we typically use. One of the most utilitarian pieces of modern equipment is a belay/rappel device with an auto-blocking option, like the BD ATC Guide, Petzl Reverso, or similar. This single piece of equipment has a variety of uses, including the following:

Standard belay from harness
Auto-blocking belay from an anchor (see Figure 4)
Lower from anchor with increasing friction (see Figure 3)
Lower from anchor with a backup (see Figure 2)
Simple 3:1 hauling system
Ascending
Rappelling
What if you drop your belay/rappel device? A key technique to know is how to tie a Munter hitch and use it to belay, rappel, or lower from a locking carabiner clipped to an equalized anchor (see Figure 5). When possible the Munter hitch should be tied so the load strand of the rope is on the gate side of the carabiner and the brake strand is on the spine side.
All of these skills and techniques should be practiced and perfected at your house, in the climbing gym, or at the local crag, in a setting that has minimal consequences if you get it wrong. And please take the time to read the instruction manuals that come with your equipment. They are packed with invaluable information and tips.
Through time, practice, observation, and reflection we start developing the necessary skills to be a truly competent partner, with the skills to use an alternative system when we, or our partner, can no longer climb, belay, lower, or rappel due to circumstances. I know for certain that we cannot possibly plan for everything that might happen in the mountains, but we all have a responsibility to our partner and the entire climbing community to be as prepared as possible when unexpected situations do arise.

Climber Communication

June 20, 2023

Educate

In the United States, many incidents and inefficiencies are caused by miscommunication within a climbing team. Often, highly consequential information needs to be relayed between climbers and belayers, and miscommunicating that information has unfortunately resulted in grave consequences. At the American Alpine Club, we have been gathering these unfortunate stories for over a century, and many incidents could have been entirely avoided had the team communicated more clearly. However, any skill that involves the use of language tends to resist standardization; it’s a challenge that has frustrated American climbers in all disciplines.

One of the first climbers to try to address these challenges was Paul Petzoldt. In The Wilderness Handbook he writes, “Unindoctrinated by the standard European techniques and philosophies of [the world war-era], I developed some new skills and ideas. I invented the first voice-signal system (now universally used in America).” American climbers have largely adopted and gravitated to some version of Petzoldt’s verbal commands for the last 100 years, because his assertions are as true today as they ever have been. Petzoldt wrote:

The human voice is difficult to hear and understand on a mountain. The belayer might be out of his companion’s sight, words do not carry well around rock projections, wind and rain sometimes make conversations impossible, even at short distances. Because of such interferences, I have developed voice signals that are brief and intelligible even when faintly heard.

Petzoldt’s innovation was insightful, and it informs the concepts espoused in this article. But, the Petzoldt voice signals that sound so familiar to so many climbers, can easily be obfuscated by a busy crag, dialect or nuances in pronunciation, and by the use of names within the voice signals—names distort the syllabic distinction that Petzoldt originally devised.

Communication, as a concept, has to be grounded in something less complex than language or speech or any group of practices that is so easily undermined by the nuances of dozens of individual cultures. It’s important to remember that communication is not always about language. Climbers who do not have the ability to hear, to speak, or to see have always managed to communicate with others, and those individuals climb in the United States as well. There is a need to address climber communication in a way to focuses on the essential goal climbers are trying to achieve, and language is only one of many ways climbers communicate.

In this article, we will explore why communication is so vital to climbers. We will explore the principles that should govern communication in all contexts, and from those principles we will make recommendations that are mostly likely to work in most contexts.

Why is Communication so vital to climbers?

Communication often results in establishing or relinquishing safety systems, like a belay, and establishing or relinquishing a safety system inappropriately can be dangerous.

AND

Climbing environments make communication difficult. Climbers find themselves in cacophonous surroundings (windy and rainy conditions, busy crags and climbing gyms with lots of competing voices, loud environments like roadsides, roaring rivers and streams, chirping and singing wildlife). Climbers are often out of sight of one another, making traditional nonverbal communication difficult.

climbing commands; multi-pitch climbing communication — Climbing environments often make communication difficult. The sound of the ocean, in this case, makes it important address the fundamental principles of effective climber communication before the climbing starts.

Fundamental Communication Principles

Fundamentally, all formal climbing communication serves to mitigate the inherent hazards of climbing. Many of the climbing commands typically employed concern management of the rope system, which in turn affects the belay and the security of the person being belayed. The simple command “On belay” may be the best example of a rope system command. An additional set of commands exists to address the hazard of falling objects, “Rope!” and “Rock!” being the most prominent examples.

Effective formal communication in a climbing system relies on commands that follow three foundational principles:

Communication Agreement. Communication between climbers and belayers should be anchored to a script that is agreed upon prior to the need for the communication.

Communication Precision. Communication should strive to minimize the amount of oral traffic needed to relay information between parties.

Communication Action. Communication should imply an impending action, and therefore should unambiguously initiate that action. Communication also may be used to affirm the completion of an action.

Communication Agreement

Climbing commands are only effective if all members of the climbing party agree on what commands will be used and the explicit actions they imply. For example, there are a number of commands associated with eliminating slack from a belay system, including, “Take,” “Tension,” “Up rope,” and “That’s me.” Each of these commands carries a nuanced meaning that must be known by the belayer in advance in order for her to respond appropriately when her climber issues such a command.

agree on your climbing commands from the start — Every climber can appreciate what it's like to call for tension in the rope system. Paul Petzold originally specified "TENSION" as the preferred voice signal, because it has two syllables, just like all the other commands that involve tightening the belay. Today, "TAKE" is a common command, but the single syllable can easily be confused with "SLACK," which is the opposite of what this climber wants right now.

Establishing different formal climbing commands prior to every climbing outing with a new partner can inconvenience the climbing experience in little ways, but it's almost always worth the a little inconvenience at the beginning of the day in order to avoid an accident. Once the communication agreement has been established, a climbing team can default to that agreement until the conditions or the context necessitates an adjustment.

There are common tropes and patterns that speakers of American English will recognize, regardless of region or background. Still, slight variations persist from one group of climbers to the next, and climbers should engrain the ritual of affirming their communication strategy before the climbing outing begins. The most common theme in miscommunication-related incidents involve climbers who neglected to have a vital “agreement” conversation prior to their climb. A simple conversation would have alleviated the confusion.

Communication Precision

Another common theme in miscommunication is over-communication. The climbing team might attempt to rely on informal communication and conversation when precise and unambiguous commands are needed. The communication might be redundant and therefore unnecessary. In both cases, the climbing team fails to appreciate that precision (communicating a precise action, no more and no less) is a fundamental concept.

When conditions are challenging, informal communication should be entirely eliminated to prevent miscommunication of important formal commands. For example, if the leader has climbed around a corner and into the wind, she would be wise to only use formal climbing commands with her partner to prevent being taken off belay prematurely.

Similarly, redundant commands over-communicate and create ambiguity. Some novice lead climbers use the commands “Clipping” and “Clipped” to inform their belayer that they will be clipping the rope into a quickdraw. “Clipping” implies that the leader will need additional slack to clip the carabiner; the formal command “Slack” is already used to alert the belayer to introduce slack into the belay system. “Clipping” is therefore a redundant communication.

“Clipped” suffers from problems with both redundancy and ambiguity; two meanings may be implied. First, the leader may be asking the belayer to remove unnecessary slack from the belay system (in which case a number of commands may do the job). Second, the leader may also be asking the belayer to check the clip: is the leader back-clipped? Z- clipped? Often, this task is impractical or impossible for the belayer to accomplish. Finally, both, “Clipping,” and, “Clipped” are unnecessary assuming the belayer is attentive. No system of communication, even if it is fundamentally thoughtful, can compensate for inadequate belaying.

climbing commands are a critical part of how to belay safely — "CLIPPING" and "CLIPPED" are rarely vital communications if the belayer is attentive. A climbing team that prioritizes precision will eliminate unnecessary communication in order to minimize ambiguity and miscommunication.

When communication become challenging, eliminating unnecessary command or conversation allows the climbing team to anticipate essential climbing commands based upon their previous communication agreement.

Communication Action

Communication should have a clear and unambiguous relationship with an impending action. For example, “Off belay,” is often used to initiate the deconstruction of a belay system. As any climber can appreciate, the action that corresponds to the communication is often highly consequential, and in many cases an affirmative response to the action helps signify the severity of the action that has occurred. Climbing teams will often use affirmative responses like “Belay off” to signify the completion of an important action. However, any command which does not include or affirm a call to action can easily be interpreted for something it is not intended to be, and such inactive communication should be avoided.

For example, some climbers use the command, “Safe,” or, “In direct,” to imply that they are secured to an anchor in some way. However, these commands are superfluous--there is no action for the partner to take in response to this command, nor is there a corresponding affirmation. Instead, the climber could simply say “Off belay” if intending to secure herself and belay from above as in a multipitch climb. Alternately, the climber could say nothing at all and simply request “Slack,” if cleaning an anchor on a single pitch climb, for example.

Fundamentals of Communication in Practice

The following examples explore the use of fundamental communication principles in real-world scenarios and demonstrate an application of those principles to scenarios that are familiar to many climbers.

Scenario 1: Casual cragging with lots of other parties.

Perhaps the most frequent scenario in modern climbing has the climber and belayer starting together at the base of a pitch. Whether leading or top roping, the commands used are the same. Drawing on the most common climbing commands in the United States, our climber, Maria, queries her belayer: “Jorge, are you on belay?”

As the formal climbing command is a call to action, Jorge physically checks the entire belay system, ensuring his belay device is loaded correctly, the carabiner is locked, his harness is fitted properly, the rope is running properly through an adequate anchor if appropriate, his climber’s harness is fitted properly, and his climber has tied into her harness correctly. When appropriate, Jorge also ensures both he and his climber are wearing helmets. Only after completing all of these checks and confirming them with his partner can Jorge say, “Maria, your belay is on.”

In their communication agreement, Jorge and Maria decided to use each other’s names in their verbal commands. This strategy is particularly important when communicating in a crowded location or noisy environment, such as a climbing gym or a busy sport climbing crag. In the multipitch setting, preceding the command with a name is equally important as it alerts the recipient that a command follows and ensures that adjacent parties do not misinterpret the other party’s communication for their own.

communication tactics change when at a crowded crag — With climbing teams all climbing side by side, the use of names in voice signals is an advisable part of any communication agreement.

Jorge and Maria will use each other’s names to precede all of their verbal commands today, because that is part of their communication agreement, it is a precise way to specify which commands are directed to whom, and the teams needs a way to differentiate between vital commands that initiate action and the informal banter that will surely characterize their time at the crag.

Scenario 2: Multipitch Climbing

Jorge and Maria are now on a multipitch climb. They begin a pitch sharing a stance at an anchor together, so communication is straightforward prior to the lead. However, once Maria tops out the pitch, there’s a need for terse, precise, and unambiguous action-oriented communication. Belays will be deconstructed and the climbing team will be transitioning from one safety system to the next.

In their communication agreement, Jorge had two main concerns. Jorge wanted to know when exactly to start removing his belay device. He had an experience in the past when he thought the leader said “Off Belay.” On that day, the leader was actually shouting to a rappelling party, “I’m out of the way.” Jorge took the leader off belay prematurely that day, and he never wants to make that mistake again. On a completely separate outing, Jorge was taking his GriGri off the rope when the leader started pulling up the rope. The unexpected tug of the rope yanked Jorge’s GriGri out of his hands and it fell all the way down the cliff. Jorge doesn’t want to deal with either of these miscommunication problems again.

Maria and Jorge agreed that names will be less important today on this isolated climb; no other climbers are around. They’ve also agreed that when the leader shouts “Off Belay,” the belayer will immediately shout “Belay Off.” The leader will have one last chance to object, if Jorge has misheard the verbal command. Jorge agrees to wait a short second before deconstructing the belay.

Also, the leader agrees not to start pulling up rope until she hears the belayer shout “Maria, Up Rope.” It’s important for every climbing team to appreciate that Maria and Jorge could’ve agreed on a completely separate sequence here, and a completely separate set of commands to communicate that sequence. The vital point here is the relationship between prior agreement and precision; Maria and Jorge are being conscientious about both fundamental principles.

When the rope is tensioned against Jorge or his attachment to the anchor, he’ll inform his partner by saying, “That’s me.” This signals to Maria that the tension she feels in the rope is due to Jorge’s weight and not some other potential predicament, such as the rope being wedged in a crack or ensnared around a horn of rock. Maria’s call to action with this command is to put Jorge on belay immediately. “On Belay”

Jorge can now prepare to climb, secure in the knowledge that he is belayed from above. When he is ready to climb, he can inform his belayer with a simple, “Climbing!” A reply of, “Climb on!” will see Jorge to the top of the pitch to rejoin his partner.

Note that in the above exchange, Jorge does not query Maria as to whether he is on belay. There is no need as Maria will put Jorge on belay in response to the command of, “That’s me.” Further, Jorge may not be able to see Maria as she concludes her lead. Consequently, he will likely not know for sure when Maria has established an anchor and is ready to belay. In the best case, voicing, “On belay?!” will not elicit a call to action from Maria other than to say “No, not yet,” unless Jorge happens to pick just the right moment to ask. Asking if he is on belay simply introduces unnecessary, informal communication. In the worst case, shouting, “On belay?!” may be misunderstood as “Off belay!” Maria is likely to find this rather alarming if she has yet to complete her lead.

Scenario 3: Communicating without Commands

It is possible for a climbing party to communicate unambiguously without the use of verbal commands, thereby eliminating the potential for poor verbal communication or miscommunication. Provided the party can agree up on a system in advance, this is readily achieved. Let’s revisit the example in scenario 2 to see this in action.

Maria reaches the top of the pitch and secures herself to the anchor. Because they suspected the possibility of poor communication, Jorge and Maria agreed in advance to use only the necessary formal verbal commands. As Maria is secured to the anchor, she shouts, “Off belay!”

Unfortunately, Jorge is unable to hear this command. However, he knows that there are only two reasons that he might need to feed rope to the leader. Either Maria is still leading, or she has arrived at the belay stance and is pulling up excess rope. Since Jorge is unsure which is the case, he simply continues belaying until he reaches his end of the rope. As he did not hear Maria issue the “off belay” command, he has no reason to affirm this command. Instead, he skips this and simply proceeds to the next command, “Maria, that’s me!” He then removes his belay device from the rope.

Maria has pulled the rope until it is tensioned and thinks she hears Jorge shout a command to her, but she’s not positive. Regardless, her next step is clear: put Jorge on belay. She does so promptly and shouts, “On Belay!”

Meanwhile, down below, Jorge is diligently waiting to climb. Prior to starting the climb, Maria and Jorge agreed to a 30- second waiting period. After shouting, “Maria, that’s me!” Jorge waits 30 seconds and then removes himself from the anchor to begin climbing. He does this knowing that Maria will promptly put him on belay after the rope is tensioned, a task that should take no more than 30 seconds. Jorge and Maria could have agreed to any amount of time they felt appropriate; again the prior agreement is the important thing.

After the agreed upon amount of time, Jorge bellows, “Climbing!” and makes a couple moves. He has one last chance to make sure that he is on some form of belay. He’s making sure the rope is travelling up, in the characteristic progression of a belay cycle. In this sequence, Jorge and Maria have accepted that it might also be possible that Maria is not actually belaying. It is possible that she is still leading, and the team is now accidentally simul-climbing. Even though it’s scary and hopefully avoidable, Jorge and Maria appreciate that Jorge will have to climb in that scenario, even if he’s not on belay. What choice does he have?

Meanwhile, back at the top of the pitch, Maria cannot hear Jorge, but she can feel the slack in the rope he generates by climbing. She pulls the rope through the belay system and after a few feet of movement is sure Jorge must be climbing. As a confirmation, she yells, “Climb on!”

Troubleshooting Communication Challenges

Select belay stances and pitch lengths that enable communication, when feasible.

Occasionally, verbal communication is challenging or impossible. This happens most often on multipitch routes and can result from many factors, including a pitch that traverses around a corner or crosses a ridgeline, high winds, or stretching or linking pitches. The best strategy for these situations is simply prevention. Whenever possible, select stances that enable good verbal communication, or even visual communication if possible. Research the route thoroughly to know when your partner might be out of touch. Consider belaying at an appropriate stance even if the guidebook does not indicate the stance as a typical belay point.

nonverbal climbing communication is often necessary for multi-pitch transitions — This climbing team could have chosen to belay an any number of places. The huge river gorge, the imposing rough, and the presence of other climbing parties nearby compelled the party to shorten the pitch-length and optimize communication.

The conventional wisdom is that stretching the rope and linking pitches results in a faster ascent as there are fewer belay transitions to be made. However, 15 minutes wasted shouting to a partner 200 or more feet distant certainly bears a greater time cost than two or even three efficient belay transitions.

Visual communication is helpful when verbal commands are inaudible.

Unfortunately, sometimes poor verbal communication simply cannot be prevented. This leaves a few options for alternative communication systems. A visual command system is one such solution. Such a system needs to be established in advance, but can be effective provided that appropriate belay stances are selected. Most often, a negative and affirmative command are all that is needed. For example, when the leader reaches the top of the pitch, she secures herself, then leans out to look down at her belayer and makes a slashing motion across her throat, indicating, “Off belay.” When the belayer has removed the belay device from the rope, he returns the signal. When the leader has put the follower on belay, she leans out and gives a thumbs-up signal straight overhead, indicating, “On belay.”

Beware of Rope Tugs.

A more common approach is a system of rope tugs used by the leader to communicate with the follower when she is off belay. Unfortunately, any system relying on rope tugs introduces significant ambiguity and the potential for miscommunication. For example, the climbing party may agree that three rope tugs from the leader means, “Off belay.” However, the leader might also issue three similar feeling rope tugs as a result of a potentially stuck rope or simple rope drag. If the belayer interprets this as a call to action, though, the leader may find herself unintentionally off belay for the remainder of the pitch.

Many climbing parties enjoy success with the rope tug technique, and their success usually hinges on a smoothly executed rope line, and a discipline avoidance of any rope movement that could be interrupted as a tug.

A second rope can be a communication tool too.

When climbing with two ropes, whether half ropes, a lead line and tag line, or as a party of three, the leader can unambiguously communicate the “off belay” command. Upon securing herself to the anchor, the leader’s next step is to pull up the ropes. By pulling up the trailing line first (or only one of the half ropes), the leader can clearly indicate that she is stopped at the belay stance as the lead rope is not moving.

Just like the rope tugs, there can be opportunities for ambiguity here. It helps for the climbing teams to consciously avoid these signals. If the isolated movement of one of two ropes is agreed to be an "Off Belay" signal, a leader should not move that rope independently unless she is off belay.

Radios, Cell Phones, and Technology

FRS radios are another option and can ease communication considerably over long distances or in poor conditions. However, radios have a number of drawbacks, including weight and costs. Further, radio communication quality varies, both in transmission clarity and range. Additionally, radios rely on battery power, yielding an additional battery to manage. Should batteries die, over- reliance on radios may also leave a party ill-prepared to use an alternative form of communication. Despite these costs, radios can be effective and beneficial in appropriate contexts, such as multi-party climbing, expeditionary climbing, and complex ski descents. Similarly cell phones and text messages have a comparable potential and drawbacks. These technologies all present the same conclusion to a climbing team: do not rely too heavily on technology. Climbers have been communicating quite effectively without these technologies, and those traditional communications skills have value.

LOWERING ERROR – NO STOPPER KNOT

A PERSONAL STORY FROM THE EDITOR IN CHIEF

One of the most common incidents reported in Accidents in North American Climbing is lowering a climber off the end of the rope (specifically, allowing the end of the rope to pass through a belay device, causing the climber to fall to the ground). As the editor of Accidents for the last seven years, I am all too familiar with this accident type. Yet late last year, I allowed it to happen to me.

In sharing this story, the last thing I want to do is blame my belayer. I firmly believe that climbers are largely responsible for our own safety, and, as I’ll explain, I had enough information and know-how to make much better decisions before starting up this route.

The climb was our warm-up on a sunny October day at Staunton State Park in Colorado. The Mountain Project description of this 5.9+ sport route said it was 95 feet high and that you could lower with a 60-meter rope with care. We had brought a fairly new 60-meter rope to the crag. The pitch was obviously long: I couldn’t see the anchor over a bulge up high, and the description said there were 14 protection bolts. But all these clues didn’t prompt me to tie a stopper knot in the belayer’s end of the rope before heading up.

During the long pitch, I made a mental note to tell my belayer to keep an eye on the end of the rope as I lowered off, and I thought the same thing as I rigged the anchor for top-roping. But I couldn’t see the belayer on the ground until I had lowered for 35 or 40 feet, and by then I’d forgotten my plan to warn the belayer to watch the ends.

Three or four feet off the ground, as I was backing down ledges at the base of the climb, the rope end shot through the belayer’s device and I tumbled to the ground, knocking over the belayer and rolling across a stony belay platform. Fortunately, neither of us were injured, but we were both badly shaken.

Did I feel stupid? You bet I did. I can’t tell you how many times I’ve written some form of this sentence in the pages of Accidents: “A stopper knot in the end of the rope would have prevented this accident.” I even urged readers to make a pledge to tie stopper knots in an editorial a couple of years ago. How could I have neglected this basic step? It was complacency, plain and simple.

No one is immune to mistakes. The only way to ensure you’ll have a stopper knot when you need it is to tie one every time. (Or you can tie the belayer’s end to a rope bag, or the belayer can tie in to close the system.) Every time. It feels silly for short pitches, but it forms a routine, so you’ll be prepared when it really counts. Tying the knot also subtly influences your climbing partners and other climbers at the crag; hopefully, they’ll develop their own good habits.

The Mountain Project description for that climb at Staunton has been revised, and now it should be clear that a 70-meter rope (or some easy downclimbing with a 60m) is needed. But ropes shrink, ropes get cut, your partner might have forgotten which rope he brought. A stopper knot is the ultimate shield against bad beta. It’s also a wonderful antidote to complacency.

I got off easy last October, and I’ve finally learned my lesson. Closing the belay system takes only seconds, and there is no downside. So, please, don’t repeat my mistake. Just tie the darned knot.

THE SHARP END PODCAST

Back in 1982, Jean Muenchrath and her partner summited Mt. Whitney as the culmination of a winter ski traverse of the John Muir Trail. On the summit they were caught in a severe snow and lightning storm. During their attempt to escape the mountain, her partner took a long sliding fall, and then Jean, trying to get down herself, also fell and bounced down through rocks for more than 150 feet, enduring massive trauma. Listen to this episode to hear a true story of tenacity and survival. The Sharp End podcast is sponsored by the American Alpine Club.

MEET THE RESCUERS

Dr. Christopher Van Tilburg, medical director for Mt. Hood rescue teams, gives us an update on climbing and COVID-19.

Home town: Hood River, Oregon

Christopher Van Tilburg near Everest Base Camp, Nepal.

Volunteer and professional life: I’m a rescuer and medical director for Hood River Crag Rats and medical director for Portland Mountain Rescue, Pacific Northwest SAR, and Clackamas County SAR. Basically all the areas around Mt. Hood. My day job is working for Providence Hood River Memorial Hospital in clinic and the emergency room, but also at the Mount Hood Meadows ski resort (21 years!). Finally, I’m the Hood River County medical examiner and public health officer, which is a good complement for public safety and SAR work.

How did you first become interested in search and rescue?

I grew up with parents who spent lots of time volunteering in the local community and abroad. They were involved in the Friendship Force, a person-to-person exchange program, and Christian Medical Society. Initially I became interested in wilderness medicine through doing medical relief programs. Then, in medical school, I realized it was a way of merging my passion with the outdoors, medicine, and my interest in volunteering.

Any personal climbing accidents or close calls?

I almost died on Mt. Hood in an inbounds ski accident. One weekend we had six inches of rain followed by freezing temps, so the snowpack froze solid. Then we had a foot of snow. I fell and ended up having emergency surgery. It put things in perspective: Things can go bad at any time, in an instant.

What sort of work are you doing with SAR teams in relation to COVID-19?

I put together or assisted with most COVID-19 protocols for the teams where I am medical director. It was particularly challenging because recommendations changed as the pandemic evolved.

Given that most of our readers are climbing outdoors, how worried do they need to be about catching or transmitting the virus?

Outdoor activity is very low risk. Probably the biggest risk is driving in a closed vehicle to the mountain or crag or sharing a tent. I’ve been vaccinated since very early, but I—and my ski buddies—still wear a mask on the commute up the mountain. Vaccination limits risk, wearing a mask limits risk, washing hands and trying to keep your distance limits risk. Employ these three things and you’ll be much safer.

What other precautions can climbers and mountaineers take?

Forming a pod of people with whom you climb regularly will help. Then, do a quick safety check before leaving the house to pick up your buddy: Are you sick? Have you been exposed to someone sick?

With vaccination increasing and so many states opening up, even as COVID variants are spreading, how should climbers adjust their risk assessment during the spring and summer months?

Right now, keep wearing a mask. We don’t know yet about variants, how effective the vaccine will be. We also have many cases of people vaccinated but still getting COVID-19. So, I’d say, don’t be too eager to stop wearing the mask.

Share Your Story: The deadline for the 2021 edition of Accidents in North American Climbing is April 30. If you were involved in a climbing accident or rescue in 2020, consider sharing the lessons with other climbers. Let’s work together to reduce the number of accidents. Reach us at [email protected].
