I've been asked to complete a risk assessment for hauling gas cylinders onto roofs, pulling them up using a rope by hand.
Has anyone done this type of thing before? I've no idea about the kinetics involved with this type of handling, or if there are any limits on what can be hauled. Any help is appreciated.

A little more info would be required - what size, shape, weight, also contents would be an issue - I wouldn't want to use an acetylene set just after it has been hauled up on a roof!!
I'm assuming that there is no other way of performing this task - internal access, scaffold access, using a long reach fork truck etc to get them up there ?

Al,
as always the basic rule is 'if it ain't safe, don't do it'. Forget the manual handling problems for a moment. There are so many things that could go wrong with the practice you outline, there really shouldn't be any debate about the necessity for finding a safer way of doing it....
(Cylinder slips from home made rope sling / knot comes undone, cylinder falls and.... / man gets pulled over roof edge when cylinder catches on obstruction / man falls over edge when trying to reach down to lift cylinder over the gutter... / rope frays on edge of roof and cylinder kills man below...../ man jerked over edge when starting to lower used cylinder...)
There are safe alternatives....
Of course, if you've accepted the lowest tender from your select roofing contractors, and they have now asked you to undertake their risk assessment.... perhaps its time to get another roofing company in?

AL,
We used to do something similar with calibration gases, we now use remote techniques which eliminate the risk. To lift safely a set of lifting kit was used, similar to that a rock climber would use. This has fail safe devices and could easily be used and setup after a little training. To further reduce the risk, we used the smaller sized gas bottles, with lifting handles.
I would recommend contacting the Source Testing Association (www.s-t-a.org.uk), as they can supply the lifting gear and may also be able to advise how you can undertake this task safely.

The correct address for the STA is www.s-t-a.org
By all means check out the lifting equipment they supply - it works OK but you may need to put the cylinder in a container prior to lifting to provent the cylinder slipping out of the strops - but instead of buying from the STA you can source the same kit from www.inglesport.com at a fraction of the price.

Difficult to envisage a scenario where I would even attempt this as the safest option!
Anyone trying to do this while complying with LOLER will need the judgement of Solomon.
Good Luck,
Laurie
