Hello.
Can anyone give any information and advice regarding requirements for short duration work on small flat roof areas. This could be anything such as a porch, garage or extension for example. Obviously an assessment of fragility is taken and sensible general precautions employed, but to go the whole hog of special access equipment, erecting edge protection or installing equipment to limit movement of the operative etc. would be impractical and not commercially viable for such short duration work. The work in question is drilling a few holes in the house wall, injecting cavity wall insulation material and plugging with a wad of cement. Access to the flatroof area is by restrained or footed ladder.
Thanks in advance of any assistance.

Whilst I accept it is short duration, I assume one must carry a reasonable piece of kit to inject said material, this must make ladder use extremely difficult.
It is to be commended yo have posted this question as I believe your industry along with many others has received much poor press and to actually come her to ask means you take the safety of your operatives very seriously; with that in mind is it not worth the investment to the chaps to ensure their safety? Yes, it is short duration but the event must be frequent so you would get your investment back very quickly.
I assume you can't fill the entire area from this one point and that you must move the ladders, it actually gets quite frequent, the use of ladders that is.
Depending on how many teams you have out there, I would have thought a bespoke system could be designed or adapt a collapsible podium tower, for instance.
All the best

Thanks for your comments CFT. The part of the job using ladders is covered by a safe system of work involving ladder restraint and safety harness system. The problem comes when parts of the house can't be accessed from the ladder and the roof surfaces have to be mounted. It is only short duration work. The material injection is not heavy or bulky work - just a hose connected to blowing machine in the van. Access equipment such as towers would not be practicable and in many cases not physically possible in the locations under consideration. We do use towers with span board where possible such as above a conservatory, but then restricted space and access in domestic gardens means this is not always possible.

My earlier post appears to have a few letters missing, I apologise for the errors.
What about a piece of equipment that drills and injects without the need for WAH, in Canada they had this machine, it clamped to the wall ran up a rail system, drilled and injected, a small camera identified saturation factor; there has to be a way to eliminate the constant need for ladder step use.
If you do decide to continue this way the value of your RA will only stand up if you truly have control measured the works.There have been many such fatalities in post construction associated works including the domestic market.
Hopefully a specialist in this industry may come along to offer valuable advice.
All the best

When it gets tricky make sure they wear BS standard rock climbing hats aswell.

Alan,
I agree with CFT that it is great to see people thinkinig about this type of work and how to sensibly manage it.
I have looked into something similar with working on top of portakabins, email me direct and I'll forward on to you.
It is a mobile roof anchor that a person can clip onto with a fall restraint lanyard as opposed to a fall arrest (bunjee) meaning they should'nt ever get to the edge.
failing that many access ladders are now being supplied with many sizes, small platforms and a handrail all of which collapse which may fit the bill?

Safety Medic,
I too work with Portacabin type structures and am constantly looking at improvements in working at height systems.
Could you forward details of the mobile roof anchor system that you are referring to, so that i can have a look at it. Many thanks
