If you talk about adding a tensioned belay line to your system, you’re bound to develop some tension in your conversations with people who are not yet a fan of a tensioned belay line. The most common paradigm is to have a loaded main line and an untensioned, slack belay line; this is especially true in the fire service. Recently, however, there has been a bigger push towards sharing the load on both the main and belay line.

There are a couple of reasons for this push. On the fire service side of things, the advent of a device like CMC’s MPD which is able to serve as both a lowering device as well as a competent belay device, has made it possible for departments to capitalize on the advantages of a two tension rope system while still having a piece of gear that meets the ubiquitous NFPA standard. The second reason for the recent trending towards having a tensioned belay line stems from some extensive research into the topic. At the forefront of this charge is Mike Gibbs and his company, Rigging for Rescue.

Just what are the benefits of having a tensioned belay? As you can see from the videos below, the load falls quite a bit less on a loaded belay line. This is because the stretch that would occur in the belay line is taken out by loading the belay line prior to its activation. This is a good thing! The longer you fall, the more likely you are to get run over by the basket or hit another object on your way down. In the case of a dual MPD system, you also get the added benefit of having a mirrored system at the anchor. It’s only one device to learn how to use, which is a nice added benefit if your team doesn’t get to practice as much as you might like. Check out a pretty in depth look at tensioned belays at :

The following tests were all performed by Rigging for Rescue and used a 200 kg test mass, 30m of 11mm rope in service (except for the last one, which is 10.5mm dynamic) and a tandem prusik belay. The notable differences in how far the load dropped before stopping comes from tensioning the belay behind the prusiks.

While it obviously is not for rescue, the concept of wedging the bicycle between two tensioned highlines is an interesting thought. If you have any thoughts on how to apply it to rescue, I’d love to hear them.

If you’re pulling on pulleys, multiplying the power of your polyester, performing a panoply of pick-offs, or trying to find a towel to wipe the spit off of your computer screen from reading so many “P” words in row; take a look at the videos below. They are each a description of how pulley systems work and are in order from simple concepts and explanations to a little more involved. You might know this stuff cold or it may be a good review. Either way, watching these videos is a fun and easy way to make sure all of the people on your team a staying fresh on pulley systems.

This first video is from the old Bill Nye the Science Guy show. If the opening cartoon brings you back to your youth, you can also look for “I’m Just a Bill” from Schoolhouse Rock. It must have been the same animator. Thanks to Phil Box at Rope Test Lab for posting a link to this

A little up the food chain is this classroom type demonstration from New England Rope:

Here is Pat Rhodes going over his 5 rules for a Mechanical Advantage system.

Dude, I Just Sharded

What, climbing up the outside of the Shard in London is not what you were thinking?

Six activists from Greenpeace were protesting oil drilling in the Arctic and decided to let the world know about it by shouting it from the roof top. The roof they chose, however, was the top of the Shard in London which is 1017′ high. It took them 15 hours to make the climb up the outside of the building. From looking at all of the pictures, it sure looks like they were well prepared to make the ascent without trouble.

As a rescue consideration, it sounds like there were several points along the route where a rescuer could have accessed a climber without having to start at ground level. Letting them get to the top to make their point and then arresting when they came in was probably the easiest way to deal with the situation without any snafus and without placing anybody in additional danger. Should it have been necessary though, this kind of climbing and exposure is certainly outside of the normal scope of the urban rescuer. All the more reason to train and be equipped for just such a rescue.

Here is some video from the climb:

Climbing that is a little less well planned is the focus of the story Height of Stupidity which highlights the exploits of British youth who free climb cranes and other high structures. Ah, the invincibility of youth ! Sooner or later the inevitable will happen and somebody’s grip won’t be as strong as it was yesterday or they had a moment of clarity and decided they were scared and are hanging on for dear life. Whatever the case may be, somebody is going to have to go and get them. Just as with the Shard climbers it is going to take some lead climb skill and in this case, will also require a harness be put on somebody who doesn’t already have one. Hopefully your team is prepared for that. If you don’t have a manufactured victim harness, make sure the team knows how to fashion a webbing seat around somebody who isn’t willing or able to lift their legs up to slide into a harness.

Stay Safe!

Enrollment is now open for our Modern Technologies in Rope Rescue. The class will be held August 24 and 25 at the Lancaster County Public Service Training Center in Lancaster County, PA at a cost of $295 per student.

This class covers multiple versions of the bowline along with some pretty god reasons to consider them, several uses of the AZTEK kit, a thorough introduction to the Two Tension Rope System concept with the MPD, and the use of the Arizona Vortex Artificial High Directional in some pretty typical urban setup configurations as well as some Rescue 2 Training exclusive uses of it in a few of the Appalachian Doortex configurations. As you can see in the pictures below from our last class, we did a good bit of work with the Rock Exotica UFO. One particularly challenging and fun scenario was to change the direction of our main and belay lines 180 degrees on an anchor that was free floating in the middle of the stair landing. There was also some excellent use of the UFO to simplify the rigging of a Two Rope Offset.

In addition to the Arizona Vortex, Appalachian Doortex, MPD’s, UFO’s, and AZTEK’s, we’ll also have available for use in this class three new products (some not even on the market yet) from Rock Exotica:

The little brother of the UFO; the rockStar.

The Enforcer load cell; which features swivels at both ends, a digital readout, and Bluetooth transmitting capabilities!

The AZORP (Arizona Omni Rigging Pod); an add on used to increase the already amazing flexibility of the Arizona Vortex.

Here are some pictures from our last MTRR class; we did some heavy duty 3D rigging along with some urban AZV usage:

This class is different each time we run it and we’ve developed new techniques each class with input and ideas from the students. If you’re interested in seeing and helping develop what’s on the cutting edge of rope rescue equipment and techniques, contact Kelly to reserve a spot in this popular class.

Back in the Swing

Well, after finally getting off of a 3 month ambulance rotation on “The Soulcrusher”, I’m hoping to be back in the swing of regular posts here on the website. In the vein of getting back in the swing, here are a few unique things related to ropes and swings:

First up is the world’s most expensive swingset, probably the most portable, but you’ve got to pay for the privilege. I try to keep my hands on rope at least once a day; since this day was so beautiful, I decided to take out the ol’ Arizona Vortex and goof around a bit. Because there is no cliff in my yard (yet), I had to settle for a flat land configuration. I used my AZV, a couple of AZTEK’s, a bosun’s chair, and a 4 year old. Here’s the result:

Of a more daring nature is the rope swing as pioneered by rock climber Dan Osman. While he ultimately died doing one of these jumps, it is pretty neat to watch the cajones this guy has to be able to do this stuff. He basically sets up a highline and, with a separate rope attached mid span, takes a free fall jump perpendicular to the track line. When the separate rope he is attached to comes tight, he goes for one hell of a long swing. I guess that, with the rope stretch and moveable mid span anchor, this is greater than a FF 2. If anybody agrees or disagrees, I’d love to know.

In stark contrast to Dan, I present the world’s slowest, yet safest, rope swing. Here is a shot of the rope offset that we set up in the last “Modern Technologies” class in Lancaster, PA. We had a main and belay coming from each side and connected to a Rock Exotica UFO to help keep all of the attachment points ultra clean. A CMC MPD was used on each side to control the main lines and and i’D and Petzl ASAP used for the belay lines.

The Smoking Prusik

Pretty awesome video just posted on youtube from a Pat Rhodes class in Australia recently. While testing the “what ifs” of a trackline failure, video was taken of a prusik capturing the load on the horizontal control line. You can see smoke coming off of the prusik/rope interface after the trackline is failed. Because I wasn’t there and am only guessing: I wonder if instead of smoke, it is actually steam from the moisture in the rope being cooked off ? Either way, it is very cool to see. Thanks to Richard Delany and the Rope Test Lab for making this type of video available on their facebook page. There is a ton of excellent information and discussion going on there. Check them out!

While not quite as cool as the Appalachian Flagpole (or a smoking prusik for that matter), this video from the manufacturer Kong shows something like an App Flag and Gin Pole hybrid. I like the technique of being able to hook your haul system to your gin pole. It’s not really mind blowing, but just another cool incremental advance in the world of rope rescue.

While the Arizona Vortex is usually thought of as an industrial and wilderness rescue piece of equipment, it’s no secret that I think its full potential as a tool for the urban rescuer has not been fully explored. With that in mind, we are constantly trying (occasionally failing) to find out how to best use this tool to our advantage. We’ve been working on different configurations of the Appalachian Wedge Pole (AWP) lately.

The first and perhaps the most useful version of the Wedge Pole is used to create anchors in a hallway where others might not exist. While no permanent name has been found yet, and because it appears to be bombproof, we’ve been calling it the Atomic Wedge Pole. Or Atomic Wedgie for short. As in: “Hey give him an Atomic Wedgie quickly, so we can get on with this rope rescue. ” But again, no permanent name yet.

Below are some pictures we took during the discovery phase of these anchors, a scale model so to speak. They were loaded with a couple of guys giving it all they had, leaning into the load line. It was an initial test to see if the anchors would move at all. The next step in the process will be to load these with a one person load and operate a raising and lowering system. Then on to a two person load.

A slightly more complex version that allows for a longer haul field that runs toward the edge.

Some techniques might be setups in search of an application, the picture below being one such example. I envision using this above a hole in a hallway, where there are no other anchors present. This might be more of an industrial confined space setup, but it’s neat to see in action.

These pictures above are of urban usage, but we developed the technique out on the rocks. Here are two pictures of the first AWP setups, one horizontal and one vertical, from when the idea first struck.

This last picture comes to us from the men of Group 2 on Rescue 1 with the Boston Fire Department. They constructed an Appalachian Lean-To and changed the direction of the haul line 90 degrees at the head resting on the floor. To counteract the resultant force that wants to lift the left leg away from the wall, they front tied the setup to an anchor spanning the doorway with two AZTEKs, one of which is doing the job of keeping that left leg in compression when it naturally wants to pull away from the wall because of the COD on the head. Good job guys!

Why Don’t We Drill More?

I don’t mean drilling as in training ( I’m sure that’ll be another post), but drilling as in: taking out a drill and putting a hole in a wall to make an anchor point. It’s just not something that I’ve heard talked about in the fire service rope rescue community as a viable option for anchoring. I’m not sure why though.

We’re pretty comfortable putting holes in roofs, breaking windows, forcing doors, etc… We might even be comfortable drilling holes for anchors in a building collapse situation in order to lift a slab of concrete. Bet when it comes to rope rescue; No Way! Maybe that will change in the future.

Looking at bolting initially, I was surprised by how relatively simple and quick it is to do. There is no voodoo knowledge or ninja rope skills required. The key points are to drill to the correct depth, far enough away from an edge, and to get the dust out of the hole before inserting the bolt. All of that information is available from the bolt manufacturer. In the video below, I’m using a 1/2″ diameter 3 1/2″ length Hilti KB3 rated at over 6000 pounds of pullout force. The Fixe hanger is rated to over 6000 lbs as well. Those aren’t bad numbers. Drop in a couple of more for your system and you have a pretty bomber system with very little effort. Before, a blank concrete slab was a thing to for the urban rescuer to fear. Now, it could be looked at as something to seek out!

Keep an eye out when you walk through buildings on routine calls. Look around for the concrete columns and beams to see where you could drill. I did this and was amazed at where I now feel comfortable knowing I can set up a system.

As seen in the video below, it takes roughly two minutes to drill and clean the hole, set the bolt and hanger, and finally torque it to spec. There are some tricks to keep you from cranking on the nut too much if you don’t have a torque wrench, like using a stubby box wrench. You just can’t get the kind of leverage needed to overtighten unless you are REALLY cranking on it.

So get out there and start drilling!

Enrollment is now open for our Modern Technologies in Rope Rescue. The class will be held March 30 and 31 at the Lancaster County Public Service Training Center in Lancaster County, PA at a cost of $280 per student.

This class covers multiple versions of the bowline along with some pretty god reasons to consider them, several uses of the AZTEK kit, a thorough introduction to the Two Tension Rope System concept with the MPD, and the use of the Arizona Vortex Artificial High Directional in some pretty typical urban setup configurations as well as some Rescue 2 Training exclusive uses of it in a few of the Appalachian Doortex configurations.

Below are some pictures from the last MTRR class in Lancaster. It was during this class that the Appalachian Flagpole was developed. The AF is designed to create a high point for grain silo rescue while not having to rely on the lightweight roof for support. A couple of the pictures show its first inception. The picture of the AF with the an MPD attached to the A frame head (next to the conex boxes) is where it is currently at. It is another high directional/anchor combo.
