Ropes and Knots for Roof-Safety Life Lines

- This is an instructional video aimed at students studying solar technology. It discusses ropes and knots related to life lines for working safely at height, when installing solar hardware on a roof; however, it is als oappropriate for anyone wanting to learn introductory information about rope and a few very useful knots used in climbing, fall-arrest, etc.
Enjoy! - แนวปฏิบัติและการใช้ชีวิต
What an absolute pro. Well done Mate! Easy on the ears, lovely work environment, love hearing the flag pole clanking in the background. He understands the psychology of a learner. Total witchcraft. You inspired me! Thank you! : )
This is why I love watching safety videos with old timers that know what there talking about 🙌👍👏
I have seen a lot of crappy knot vids with poor camera work and poor explanations. Yours was EXCELLENT.
My husband needs captions, probably a lot of guys needs it. Thanks
Excellent video, very thorough, great explanation. Thank you!
Thank you for a well explained, and very useful tutorial. This is just what I was looking for.
Thank you very much for a great instructional video. The how and the why, the do and the don't. Thank you again.
Thank-You very much, I now feel much safer working on 12/12 roofs.
Great explaining!
Excellent tutorial
Very good!
Hi, does anyone know a knot to use When working alone on a rope roof.Say I have one, but I have many things to lower.What knot will release When I take the stress off, so I can reuse the rope?
I love the way you explain things in your videos 😊
I am a 64 years young woman 😊 and I nearly fell off my roof whilst removing the hip high (I am 5’ 6” high), snow on my roof last winter.
So, needless to say that this year, I bought the full body safety Harness and 6 foot internal Shock absorbing Safety Lanyard with double snap hooks on it to go on my back. I would like to know what type of rope do I need, because, I weigh 215 lbs and I’ll be up on a roof that is about 25 feet high x 30 feet deep x 60 feet large and with these dimensions on one side it will be tethered to my Pick-up on one side and to a big maple tree on the other side … what would be the best length? Thanks for taking the time to read this . Nicole
You shouldn’t be doing that at 64, try contacting a roof cleaning company near you
Great video....I am Working on edge of a 8 ft roof and you fall the lanyard stretch is 60+ inches (give or take) on how much slack is in the rope that only leaves 3 ft of clearance if that to stop you is there something better that to stop you sooner?
where i live, the codes say you only need fall protection if the height is above 10 feet, unless it's a steep pitch.
What to do with the knotted rope on the roof?
I have a 50FT lifeline rope. I only require 12FT lifeline from the roof anchor. What's the best way to shorten the life line and not trip over it ?
Firstly, leave the excess at the anchor, not at your harness tie-in. Then there are several options, which include coiling the rope, using a daisy chain, or just putting it in a bag.
What is the typical attachment scenario for this knot to an anchor point?
+GrouseHiker: The Figure-8 on a Bight (backed up with a barrel-knot stopper) is considered one of the best ways to put a loop in the end of a lifeline. Some say this knot is THE most commonly used knot in lifeline and rescue work, specifically for attaching the line to an anchor point.
If the anchor point is an "engineered" anchor, it is usually designed to accept a climbing and rescue-rated carabiner -- 5,000 lb. MBS, dual-action opening mechanism for opening, and auto-locking closed. The carabiner would capture the carabiner and attach to the anchor point. Preferred would be a shared anchor, using two rescue straps, each in basket mode, and each around its own anchor point.
If the anchor point is an improvised "structural" anchor, it may require a loop much larger than is tied in a typical figure-8 on a Bight. In this case, the end of the rope can be wrapped around the structural anchor and then tied back onto the rope as a figure-8 on a bight tied with a follow-through technique.
Does that answer your question?
+tjwiltube : I watched your other videos after asking the question. Thanks for the good and thorough explanations. The 5,000 lb anchor capacity is problematic, and I doubt any of the typical, temporary roof anchors would achieve this. The problem I'm trying to solve is an improvised anchor point on a residential wall - maybe workers on a plank spanning between two ladder jacks. Taking ropes over the roof of a gable end is not a good idea. My idea (similar to your last statement) is to tie the figure-8 on a bight with a very long loop, take the loop through the soffit, into a long radius PVC elbow and into the attic. I just need to come up with framing/blocking. My other idea is to drop one link of a high capacity chain through the soffit and connect that to framing within the attic. The chain connections would be permanent and more convenient.
this was a very knotty video.
breathe and squeeze Good One! LOL

Hey bud!
You don't need to backup a figure 8 as long as you leave at least 5" of slack.
I think we would all far sooner have a backup... even cars are built with split brake systems, the Airbus A380 has four backup systems for hydrolics... Things aren't meant to fail, but if they did, yeah, I'd far sooner have the backup, just in case of a worse case situation...
Kevin Simard you do need to back a figure eight k,it because it is a tension knot. We use to fly 15 pounds per foot rails and had to As it h just in case I got hung up and lots its tension.
I want everyone to be safe
How come nobody uses a totally second line for backup? Even repelling lines are one rope draped over a pulley so it looks like two ropes but it's still one rope and if you cut it guess where you'll end up? So how come nobody uses two roped and that would appear like you're using four lines?
That is used in Rope Access. Usually, they are not worth the extra hassle, and therefore generally not used in recreational climbing and repelling, tree climbing (Single Rope Technique and Moving Rope Technique), Caving or Rescue. Also, in a Fall protection setting, there is not one rope that is constantly under load, warranting the use of a backup line.
And by the way, when repelling you generally only use a doubled rope when you want to retrieve the rope.
@@raphaelbeinhauer9242, do you trust 3,500 pound chain links at Menards?
@@1weirddoe571 Depends on the purpose. For rigging or maybe for limited Static life support (no shockloading or falling). For other purposes I would just buy a locking carabiner with a strength rating of at least 22kN. They don't cost much, you can get one for around $10.
