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.

If you’re interested in seeing what’s on the cutting edge of rope rescue equipment and techniques, contact Kelly to reserve a spot in this popular class. Call 240-462-6610 or send an email to rescue-2@comcast.net

Well it’s short notice, but we have had some significant interest in running another “Modern Technologies in Rope Rescue” class. So we’ve decided to add one more for the year.

We’ll be at the Lancaster County Public Service Training Center in Salunga- Landisville, PA on Dec 8-9 for this two day class covering a wide range of what’s new in the rope world. In particular, we will be working heavily with the CMC Rescue MPD (Multi-Purpose Device) and Two Tension Rope Systems. This system dramatically simplifies the rigging needed to execute the majority rope rescues.

We’re also going to be covering the use of  Arizona Vortex artificial high directional. While we will cover several traditional setup configurations, we  will also be showing the setup and use of the Appalacian Doortex in a couple of different configurations. Knotcraft, with a focus on the benefits of the bowline and it’s many variations, will also be covered in depth.

The cost of this 16 hour class is $280 per person. If you have any questions or would like more information, please give Kelly a call at 240-462-6610 or send an email to

Appalachian Doortex

Here are some new AZV uses we at R2T have been testing to see the real world practicality of.  There are some earlier proof of concept pictures on the multimedia page, but these were done in exposure with a two person load. They’re all versions of what we’ve decided to call the Appalachian Doortex (APD), an obvious attempt at getting some East Coast love into the rope world.

The purpose of these APD is to create either an anchor, a high directional, or both simultaneously in the urban environment. The initial thought was for use in elevators, but can obviously work to create an anchor anywhere there is a solid block wall surrounding a door. We run A LOT of stalled elevators in in the city where I work, 15 a day is about average in our geographically small city. Not many require any rope work at all, but the one’s that do can be a real pain. Have you ever looked in an elevator lobby for anchors or a high directional? Not much around. That’s the problem we were trying to solve.

The “Ram’s Head” is the first version we came up with. In this configuration we hooked both MPDs right to the head of the APD; there was no guying, tying, or anything. The foot of the lazy leg was not resting against the opposite wall. Aside from a very minor initial settling in of the APD, it did not move during the operation. It was loaded with a two person load that was raised and lowered several times. One of the MPDs was hooked up in a fashion that caused it to bind against the head of the AZV a bit because it allowed us to have the operating handle facing outward. Because of the angle of the rope leaving the MPD into the elevator shaft, this very minor binding was felt not to be an issue.

Next up is an Upside Down APD, with no clever name given yet. Maybe the Appalachian Lean-To (ALT)? Yup we’ll go with that for now.  Just another way to make an anchor/HD combo. Also loaded with a two person load, operated up and down a bunch.

Here is the close up of the dual MPD anchoring on the Appalachian Lean-To.

Below are two pictures of what we used to keep the the Appalachian Lean-To from kicking back should it have wanted to. It didn’t want to. We had a dynomometer in there to see if there was any force trying to push the ALT away from the opening. The needle didn’t move at all during the operation. We were pulling against an extra leg section of an AZV run through two 4×6 blocks with holes drilled in them to keep the leg section from resting on a small, roll prone contact point on the hoistway doors. We’ve been calling them “Brace Blocks” (Appalachian Brace Blocks?) They worked really well. I suspect they can be used to help span doorways in buildings to create quick, simple anchors in a hallway.

While we have not tested a center pulled AZV leg to failure yet, this one was pulled to 500 lbs without any visible deflection. Further testing on this configuration will be conducted in the near future and we’ll let you know what we find out.

If anybody has any thoughts, questions or comments on this, or would like further training on operating on rope in an urban environment please feel free to leave a comment below or send Kelly an email directly at rescue-2@comcast.net.

Break Out the Violin Bow

…to play that overly tensioned piece of rope that’s supposed to be a highline! Or, at least that was my first thought until I realized that  it was an unloaded basket. Pictures from a different website show a basket with an attendant on it clearly creating a more appropriate amount of sag in the track line. I’m curious if they ever did have a victim in the basket as well as an attendant. The goal of the drill, aside from incorporating a bunch of rope skills and logistical planning, is to get a patient who is in distress to an area where they can be helped. If that is the goal, why not train with a victim in the basket?
I’m not picking on these guys in West Point, NY. There are lots of places that don’t put victims in a basket. “Safety” is the reason that I have most often heard. If “safety” of your system depends on the difference of 200lbs, we should probably use another system. “Scared” or “uncomfortable” are a much more realistic answer. I know I don’t like being in the basket on drills. Not only are you out of the rigging picture, you also feel completely helpless just laying there. And you pretty much are. But you can imagine that somebody who has NO idea what is going on (an actual victim) is going to be 10 times as scared as you are.

It’s not a bad idea to place somebody in the victim role so you are at least able to empathize with people somewhat when they are laying helpless in a basket.

Now, we’re only looking at a small scene from a moment in time, but the rigging pictured below raised a couple of flags for me. First is the use of redundant anchor straps. The second is attaching one biner to those anchor straps to hold the whole system. Just food for thought:

 

 

 

 

 

 

 

Tight!

Not so bad once loaded:

Bowline=Death?

Can a bowline with a Yosemite finish be a recipe for disaster? According to the video below  the answer is a resounding yes. That is, of course, if you are prone to loosely and incorrectly tying and dressing your knots. I think there are quite a few knots that would come undone given those set of circumstances. You can read  about the inspiration for this posting of mine at these two climbing forums:

Rockclimbing.com

Supertopo.com

Does this mean that it is a bad knot? I would argue that it is (k)not. It could be argued that it might not be the best thing to use as a harness tie in for people who are only using it for climbing. But to argue that one usage against the effectiveness and efficiency of the many variations of this knot when used for rescue, seems a like it might be limiting yourself. For instance, you can tie on bowline on the bight with a Yosemite to create a quick rope anchor, around a tree for example, with a bight to be used for connecting your friction device to; or use a Portuguese bowline to anchor an A frame as shown in the last video. I would(k)not discount a whole series of knots just because one variation of it does not fit one specific use. I might be preaching to the choir, but I still wanted to get it out there. Please feel free to leave a comment if you have any thoughts on the matter.

Here is the first video of how not to tie a bowline with a Yosemite

Here is are two video sfrom R2T friend Eric Campbell. One on how to tie a “snap bowline” with a properly tied Yosemite and the other, a couple of bowline variations for anchoring

Lastly, you can see in this video, around the :17 mark, a Portuguese bowline (with a bight and Yosemite) used to anchor the A Frame and create a rearward facing bight to attach the 3:1 tensioning system to. To do this with a family of 8 knots would take forever, not be nearly as clean, and is sure to eat up a ton of rope.

Rescue in Sedona

While Sedona, AZ is the site of countless practice rope rescues thanks to being home to a couple of rope rescue schools, it was recently time to do the real deal.

Thunder Mountain was the location of this rescue after a hiker fell several feet of the trail and down into a ravine and was unable to climb back up due to his injury. Here is a link to the story:

HERE

One thing that was interesting to me is the three hour search for the victim. As an urban fireman, it is neat to see a different perspective of FD operations in n area with more wilderness than urban buildup. I’m pretty sure that if we had to search 3 hours for somebody, most guys would think we were on a wild goose chase after about 15 minutes; and in a big city they would probably be right. It is neat to see that smaller departments are equipped to handle emergencies like this that take longer to handle. Good job Sedona FD!

 

Here is one of the pictures from the article. Interesting to note the cross about 100 feet above the rescuer and victim. I’m curious (morbidly) if this was the site of a previous fatality.

 

Monday Morning Quarterback

Posted by rescue2training on May 21, 2012

There are always things that could have gone better on every rescue. Sometimes, though, something just catches your eye as REALLY not correct and you feel the need to say something about it. So I’m going to play Monday morning quarterback here.The picture below is from an article about a dog that was rescued after it fell 30 into a well. The upshot is that the dog was rescued and nobody got hurt.

Now the bad part(s)…

The first thing that caught my eye were the rescuers pushing against the tripod to keep it from tipping over. While there are a few guys holding it up, this is not what is generally meant by a guying system ;). The reason they are doing this is because the resultant force of the haul line is wanting to tip the tripod toward the haulers. This is bad because, one, if those guys stop pushing against the tripod, it will tip over and two, it will land on their helmetless heads. As a person who has had the leg of a high directional (HD) land on MY helmetless head, I can attest to the instant headache it causes. I was lucky not to split my head open.

They could have solved their toppling problem a couple of ways:

Use an HD that has adjustable legs, like an Arizona Vortex, to account for that resultant force.

Tie the top of the tripod off in opposition to the main line.

Run the main line through one side of a double sheave pulley, down to the load, back up to through the other sheave, and tie the line off at an anchor opposite the  anchor on the haul side. This would have kept all forces on the tripod relatively equal and not have required any guys , rope human, or otherwise.

One last huge issue I saw in this picture was the lack of a belay line. I’m not opposed to a single rope technique, there are plenty of places that use it without issue and are trained to a level that allows them to operate safely with it. In light of other rigging issues in this picture, I’m not sure SRT is right in this situation. I realize a picture is only providing a narrow field of view of what happens in a fraction of a second, but it still allows us the opportunity to learn from it.

Stay Safe
