Being a fireman and a rope geek, the topic of emergency escape and belaying is a big one to me. So I’d like to share with you this video that was found, through rigorous searching of the internet, covering just those topics.

Should you be interested in the device (doubtful), the name of the company is shown later in the video.

These two videos were posted previously, but the links have gone bad. So here they are again for you to see how things can go REALLY wrong if you don’t know what the heck you’re doing. Both are from Peru. Just so it’s out there again: If you are visiting Peru and they ask if you want to ride a highline, it’s probably in your best interest to politely decline.

There is a lot to be said for how far technology has allowed us to go in the world of ropes as it relates to safety: Stronger yet smaller ropes, lightweight high strength aluminum hardware, etc… But is fun to cast our thoughts back to where the rope rescue world has ascended (that’s a pun) from. Check out the rescue drama in the youtube video below. It is from 1949 and was posted by Ron Holan on the Rope Access Technicians Network group on Facebook.

The neat part about this for me was that they didn’t use any carbiners or friction devices to lower the casualty. It was all done with friction wraps around their bodies and around rock outcrops. While this might not be how a rescue should be done now, given all of our available equipment, it is none the less a look at how a rescue can be done without any equipment.

Maybe you could use this video as an idea for a drill: Only use a Stokes basket and a rope, no hardware, to accomplish lowering a package down a building, catwalk, mountain, etc… Oh, and they weren’t using Prusiks either. They only had trust in each other!

 

 

Also pretty darn old school is this picture of Silver Spring VFD using the ladder truck for a high directional to get a Stokes basket off of the roof of a one story school and down to the ground. Thanks to our Florida friend Joe Schulman for findiong and sharing this one.

 

It’s hard to tell for sure from the picture, but it looks like the rope is just hard tied to the tip and the ladder is just craning the load.  Similar to one of our previous posts HERE , it’s also another example of how it might be easy to access a patient via ladder and use a rope system to get them down.

We have just added an Open Enrollment Class for our Modern Technologies in Rope Rescue workshop on May 17 and 18 in Lancaster, PA.This class covers a lot of ground in two days. We will discuss and use the AZTEK in many of its essential uses. We’ll also be using the Two Tension Rope System concept with the CMC MPD. Additionally, we’ll be using the Arizona Vortex in some of its traditional configurations as well as the Rescue 2 Training original: the “Appalachian Doortex” configuration for urban anchoring and elevator rescue.

Come out and try the newest equipment and techniques in rope rescue. Cost of the class is $295.

While I’d love to start the year on a high note, this video of a rope rescue demonstration brought out the Debbie Downer in me. How many rope rescue guys does it take t screw in a light bulb? Answer: 7.  One to screw it in and 6 to point out how he could have done it better and more safely.

With that in mind, I’d like to talk about the video below. There are a few things that jump out at me:

  • Firefighting gear isn’t technical rescue gear. I’d argue you are better off with the increased flexibility of your station uniform. The brim on the back of a firefighting helmet is great at keeping water and junk from falling down the back of your coat at a fire; it’s also great at hanging up on rope, railings, and everything else at a rope call.
  • While there are several examples of a worse edge transition, this one was successful, but had the potential for disaster. The mainline system was run under the fencing and the basket was placed over it. This created the potential for a pretty big drop. A belay line did not appear to be in place until the rescuer climbed over the fence.
  • There was no obvious edge protection for the main line. If the basket had dropped prior to the attachment of the belay line, it would have taken a pretty substantial fall on an unprotected edge.
  • The belay line was not along the same plane as the main line. If the belay line were to be needed, there would have been significant horizontal movement.
  • If using webbing to help lower a basket over the edge, consider wrapping a Munter (Italian) hitch around the railing rather than strong arming it.
  • A high directional would have solved most of these problems. Even just going over the fence would have helped quite a bit.  To reinforce the fence and keep it from collapsing back towards the anchor due to the resultant, a reinforcing strut could be put into place pretty quickly. Like this:

Here is a duo of rescues. Both involve rope and both involve water. They couldn’t be more dissimilar if they tried, though.

This first one is from Virginia Beach, VA where a worker on top of a water tower apparently slipped and fell and was caught by his fall protection system. He doesn’t appear to be a rope access worker; more than likely he is a brave cell tower worker who climbed over the side to do some work and slipped while climbing down or back up over the edge. That’s complete speculation on my part, but it fits the circumstances pretty well.

It looks like a pretty straight ahead pickoff with the rescuer being lowered and lifting the worker off of his system with a clearly visible AZTEK. Take a look at the victim standing in his relief step awaiting rescue. Kind of like a really small slack line attached to your harness. Not nearly as fun, I imagine. Good job by the fire department to try and do the simplest thing first: see if the ladder reaches, then set up for a rope rescue.  Thanks to Collin Moon of Elevated Safety for cluing us in on this one.

This next video was sent to us by Matt Hunt of Sterling Rope  and is now probably my favorite video on youtube! It really appeals to me for the fact that these guys are using really simple physics concepts, applied smartly, to accomplish a goal. Check out the slick use of the “pike and pivot” method as well as a two man rope winch. Not too far of a stretch from rescuing people instead of cars.

I was wondering who the brave guy was that hooked up to the car. The description says that they were able to snag a tow hook on it while standing on the ice without any problem.

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:

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:

IMG_7122

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.

Stand by for more frequent postings again. Thanks to everyone who keeps checking in!

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.

IMG_1348

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

2 to 1 Wedgie

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.

IMG_1334

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.

IMG_0407

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!

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.
