Let’s face it, the fire service is not really screaming for any new acronyms; particularly one that rehashes another acronym but with a slight twist. Yet, here I am proposing a new acronym that is a twist on an old one.

One of the more noted acronyms when calling a Mayday is LUNAR. Location, Unit, Name, Air, Resources needed. While it is adequate, I’ve always wondered why “Air” was on the list. It’s not as if we’ll say: “He’s got plenty of air, let’s let him wait a while” or “He’s got plenty of air, let’s leave this RIT bottle here. I’m sure we’ll be done before he runs out”. It doesn’t really strike me as all that important.

I’ve also wondered why it has “Resources” there. While it might be chic in fire service management to use a word like “resource”, if I were in a jam the last thing I would be thinking about would be using a word like “resource” for what I need. I need HELP, not a resource. I imagine Resource is there, along with Air quite frankly, to help make a neat sounding acronym.

 

I think LUNAR is adequate, but I am proposing a new one based on my past experience as a truckie:

LUNCH

 

Location

Unit

Name

Conditions

Help needed

 

That’s right, LUNCH. Who doesn’t think about lunch… particularly at a firehouse. Whole days revolve around it sometime and most guys never miss it. It’s unlike LUNAR in that, while the moon is out every night to possibly remind you, if you don’t leave the firehouse at night (truckie), you never get to remind yourself of it.

 

The one concession toward having a clever acronym is that I have also thought that adding your name in there was a little pointless as well. “Oh, it’s FF Byrne… F#ck him. We’ll get there when we get there”.  Without it though, we wouldn’t have the mildly smartass LUNCH acronym.

 

So… Next time you sit down at lunch, give yourself a 3 second refresher in calling in a mayday for yourself. For example:

“MAYDAY, MAYDAY, MAYDAY. Rescue Team B, FF Byrne on the Bravo side of the kitchen table, I am out of A1 sauce for my dry steak the engine overcooked. I need A1 sauce and a cookbook for the engine to read the future. ”

 

Simple as that! Seriously though, it doesn’t have to take long and it keeps your mind in the game. And if anybody can think of another word for Help or Resource that begins with the letter K, we can get rid of “Name” as well and just go with LUCK.

Take a look at the first video in the link below. It’s a news story out of Fort Wayne, IN that I assume was supposed to be a simple feel good piece highlighting the local rope rescue team. If you want to jump right to the good stuff, go to the 2:10 mark in the video. What you will see is a really big, really expensive mousetrap.

 

I do feel a little bit bad about Monday morning quarterbacking this video… but not enough to cause me not to do it.

 

First, the critical point at the Kootenay Carriage. It would appear that there are two track lines, and two upper control lines (although no lower control lines) with tails going down to the rescuer and victim. The Kootenay, however, remains a critical point. Do I think it will fail?  No. But we rig for failure caused by human factors, not equipment factors. Should that Kootenay fail though, the basket could take a major and possibly fatal swing fall.

 

Second, there is difficulty with attempting to get the basket back up over the edge after they took a ride down and back up the track lines. The reason given in the report is that the “ropes stretched”. While I don’t doubt they stretched, take a look at the link the news story below the youtube video. The second video is extra footage they got while doing the shoot. It is obvious from watching it that they were going to have this problem. While initially loading the basket over the edge you can see how far it drops down when it is initially loaded. It’s about the same distance that they are below the edge when they come back up.

 

Rope stretch? Maybe.  Foreseeable problem? More likely.  I’m curious if the attendant could have stood on the end of the basket in order to raise the head up and over the edge. Also a factor is the excessively tall bridle they use. Judging by the video, I’m guessing from the bottom of the basket to the top of the carriage to be six feet in height.

 

Third, you can see from this picture just how close the resultant is to being outside of the footprint of the tripod. When the track lines were tensioned to raise the load, I’m curious if the friction in the pulleys caused them to temporarily move the resultant until they found their center again.

Fourth, two statements made during this gave me a bit of heartburn. The first is that the “white rope didn’t work the way it was supposed to.” Ropes work exactly as they are rigged. Unless it broke under tension due to unseeable chemical degradation, it was rigging failure.  It’s hard to tell what the white lines were rigged to, but I’m guessing they got pulled up off of whatever they were on. The second statement is that “nobody was dropped…they were lowered”.  If it was unexpected and uncontrolled, it was a drop. Maybe I would have been inclined to say the same thing out of embarrassment while on camera, but lets call it what it is.

Last, neither the reporter in the basket, nor the one on the roof seen just before the tripod topples, have a helmet on. If I were running this show, it probably would have been an afterthought for me too. Having seen this video, I’d be willing to bet it would be a fatal blow if a tripod toppling like that hits you in the head, helmet or not.

I do applaud Ft. Wayne TRT for allowing this to air (if in fact they had a choice). It’s sometimes hard to admit a goof up. It’s even harder to have it on tape for guys to critique from a distance without knowing the full circumstances (me). The least we can do is try to learn from it.

 

 

More footage in the second video here:

Take a look at the video sent to us by Larry Mullin of Fairfax County FD. The video shows a technique used when attempting to rescue a suicidal person who is about to jump off of a bridge. Apparently this is for when somebody like, I don’t know, a trained psychologist is unavailable and the jumper is patient enough to wait idly by as you set up two rope rescue systems. I’d love to know what you do after you have them. Raise them back up? Lower everybody into the water? Who knows?

I’ve never had to do this type of “rescue”, but I don’t want to be hanging on to a person who wants to die for an extended period of time with no other means of attaching to them. If you’d like to know why, take a look at the second video. Which will also serve as a good pitch for some type of auto locking descender.

 

 

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.

 

 

Check out this article from Las Vegas. It’s about the new 550′ Ferris wheel that can hold over 1100 people and the article highlights some of the planning that went in to possible rescue situations.

Kudos to the Las Vegas FD tech rescue team for being proactive in the situation. It looks like, should something ever happen, that it will be a complex mix of lead climbing, aid climbing, and some team based lowering. The fact that the fire dept. was consulted at all during construction is pretty neat too. Anchors were placed inside each pod so that a system could be hooked up and 3 victims at a time can be lowered.

Neat stuff!

ferris wheel

Thanks to my sister, Caity, for pointing this one out to us. It’s not rescue stuff, but be sure to check out her awesome website spiralspiritballooncompany.com. Lots of great sculptures there!

Here are two great videos from DRR Rescue posted on youtube that show how to construct a 1-1-1 picket system, which is three pickets placed in a row.

Two things stood out to me in these videos. First, I really like the system they used to tie the pickets together. I’ve seen a few different variations on the technique, most involving some sort of windlass to tighten the webbing. Doing that requires more hardware, as well as driving in another piece of rebar. The videos show what amounts to a non working 3:1 with webbing.

The second thing that really stood out was how much force this system was able to hold. They put over 6ooo lbs of force on the system. While the picket did flex a little bit, it did not noticeably pull forward in the ground. I’m anxious to try this in the rain soaked, clay dirt around my house!

Thanks again to DRR for sharing these with the world. Be sure to check out the tutorial section on the website as well as their field guide, that thing is full of great, easy to apply info.  http://www.desertrescue.com

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.

old school rope rescue

The recent rescue by the South Walton Fire District’s Technical Rescue team in Florida is a great example of rescue where it is easy to access the victim by something as simple as a ladder, but where a rope based system might still be the best alternative for getting them down to the ground safely.

You can see in the pictures that the guys on the ground are able to guide the basket most of the way to the ground while it is supported on  the ladder and being lowered with rope.

Two quick points: If possible, I would have tried to line up my ladder with my anchors so that it was all in plumb. Maybe there is a good reason they didn’t. It’s hard to tell from just a picture.  Secondly, you can see how easily they overcame this by just having a rescuer on the roof do a very minor deflection by just pulling on the rope. It’s a good example of knowing how to easily overcome a problem by knowing a few physics tricks.

Not all rope calls are high pucker factor incidents of life and death. Sometimes it’s just the simplest way of getting  the patient to the ground. Good job, guys.

 

swfd easy access

We were messing around the other day with some variations on how to better perform the best way to get a vertically oriented basket up over a 90 degree edge, which is know alternately as the “Pike and Pivot” or “V Strap” technique.

The issue of effective, efficient edge protection for our ropes and webbing was given us a bit of a challenge until our resident old man (and connoisseur of Miller Lite on his days off) , Mike S, suggested that we try and use a Sked as edge protection. It’s smooth, tough, has plenty of places to tie it off, and is much wider than standard edge protection. We’ve dubbed it Skedge Protection.

It can only be described as having worked perfectly for this situation.

I have no idea what the long term durability would be if used as edge pro all of the time, but for what we were using it for, I’ll definitely grab it without a second thought next time.

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:
