safety ropes to chimneys?

George (dicegeorge) was thinking very hard :

A length of 6mm fine wire galvanised multi-strand wire would last for many years. Go twice around and fit three proper clamps of the correct size at the overlap.

Silly question whats it for? harnessing you whilst fiddling on the roof?

Ther ya go one at the base of the stack and one in the middle,fix a short steel pole between the two main brackts.

Eye bolt masonry anchors are the correct solution, e.g.

There is a specific type of anchor rated for this purpose, but I don't see it on Screwfix.

Are you thinking of something for "fall arrest" that will take the shock load of a person, or just something to add stability to ladders?

What's a safety rope? What do you intend doing with it?

I don't know if it's what you meant but we fixed eye bolts to various pzrts of the house wall so that we could fasten a ladder to ropes whilst working on windows from the car port roof.

It works very well.

yes, fall arrest, (for when I'm fiddling around on the roof, slipped slates etc) so the tv aerial kit is too light weight, presumably these scaffold eyes go in the brick not the mortar, but the bricks are a bit old and crumbly which is why i thought of wrapping something around the chimney stack....

Presumably so that as you're sitting on the ground contemplating the frayed end of your bit of rope and wondering what to do about your broken leg, the chimney stack falls on you and saves you having to think about anything at all?

TV aerial kits too light? if anything your chimney stack will be less insecure.

I would not wish to trust my life on a typical lashing kit. Eye bolts are fine, if they are tested for soundness, but on a crumbling brick scenario they might pull out or the mortar might be old and weak. I think he has the right idea with something lashed around the chimney, but something a bit stronger than an antenna lashing kit.

into the brick...And I did say two of these lashing kits and a steel pole clamped to the brackets...if anything is going to give its the chimney's mortar.

I would not want to trust my life to a chimney. Most chimneys that I have encountered have been much more fragile than the walls of the structure that they are attached to.

If one is talking about a chimney made from engineering brick and a hard mortar, possibly. But the average domestic chimney is only as strong as it needs to be and not designed for restraining a fat arse falling from the sky.

Fat arses can't get on roofs anyway. :-)

In article , George scribeth thus

And there are a LOT of chimneys held together by aerial lashing wire;!...

oh yes I can.

A fat arse shouldn't be fiddling up on a roof...their reflexs are to slow to pertain a safe balance should the need arise.

Wuss. Rod Hull would do it.

Yebbut he had Emu to rescue him if he fell.

So would quasimodo...at least he will have something to fall back on.
