Hi, one here for those Construction bods to ponder:
If when moving a tower scaffold it ends up on its side could this be classed as a collapse - being reportable or simply a "topple". Is there a difference?

Hello Tigers. I take this is a Aluminum Tower you talking about. It is reportable if it is 5 meters or more Under RIDDOR. But what concerns me is to why it would collapse in the First Place.
(1) Has it been Erected by a PASMA trained operative, even Qualified Scaffolders Now Days are Forbidden from erecting ALLY Towers on most Projects.
(2) Has it been Erected on Firm/Flat ground.
(3) Has the 3 Times the Smallest Base Dimension being Exceeded - If so has Outriggers being used.
The Access Industry has Gone a bit Cuckoo, where say a Advanced Scaffolder with numerous years experience can not Erected a Ally Tower due to him not having a PASMA card but a normal guy off the street having a card can erect the tower.
Just a thought to get the Ball rolling.

Agree with your general sentiment, but do advanced scaffolders have experience of the safe ways of erecting tower scaffolds? May sounds like a stupid question, but is there a possibility that a PASMA course may teach them something difference? If so, then it would seem logical to take this stance.
Advice from an "advanced scaffolder" who has also sat a PASMA course would be useful :-) Did it teach you anything new or was it a waste of time?

Thanks AllenFS Being resited over a shingle base - castors dug in and in the words of the contractor "toppled", but I have my thoughts.

If over 5m high, I would say yes, reportable.
Regarding teh other commenst arising in teh thread:
It's perfectly reasonable that tube-and-fitting scaffold and ally towers are treated as different qualifications. They are completely different things and the safe erection method for an ally tower is no more obvious to a tube-and-fitting scaffolder than it is to anyone else that's occasionally seen one / been up one. So in my view, it's perfectly reasonable that an advanced scaffolder who doesn't have a PASMA qualification can't erect an ally tower, but a PASMA operative who doesn't have a tube-and-fittings tickjet can.
I don't expect a holder of a race driving licence to be allowed to drive a FLT or vice versa.
I'm not sure what "normal guy off the street" means when teh "normal guy" picked "off teh street" just happens to have a PASMA qualification. That's not a normal guy off the street in my estimation.
You don't use outriggers when moving a tower. It wouldn't move if you did.
Whether it's a safe operation to try and move a tower over 5m tall on a soft (shingle) surface is a different question.

If you were moving it (as OP states), presumably it wasn't in use as a working platform? Presumably outriggers removed for transit.
Pragmatism suggests the answer in that instance is no.
It was an object (a work article) that fell over.

I tend to agree with Ron. Moving it, no-one was on the platform, I hope, so not 'in use'.
And so likely not reportable if it was a pot-hole or obstruction or collision that caused the topple over.
But if it was incorrectly assembled or there was some attachment that caused the topple then maybe reportable?

I thought about that argument, but I don't think it's valid. RIDDOR requires reporting of "Collapse or partial collapse of a scaffold over 5 metres high" and not (for example) 'of a platform in use' or even 'of a working platform'.
If the perceived (by the architects of RIDDOR) hazard is stuff falling on people, it's irrelevant whether it was actually in use when it collapsed - and most of the cases of scaffolds up the face of buildings peeling away and falling in the street would not be reportable, because they mostly seem to occur when the scaffold is not actually occupied / in use. It's not credible that they wouldn't be classed as a dangerous occurrence just because they happen to take place after 5:30 or at the weekend...

I don't disagree with you achrn in the context of facade scaffold collapse etc. But in those specific circumstances, the scaffold is built or under erection in the intended fixed location.
The OP describes something being moved (which just happens to be a tower) which fell over.

Many mobile tower scaffolds need to be partially dismantled before being moved if to remain stable in the absence of outriggers.

Cheers Peter. I was just about to ask how high the mobile tower was whilst they were moving it. Pasma themselves say that a tower should be reduced to a maximum height of 4m IF it has the stabilisers at their correct angles AND they are 25mm above the ground.
If you cannot do this, you must reduce the tower to 2m. The vast majority (if not all) manufacturers agree with this.

They shouldn't be removed during transit, Ron. Just lifted 25m.

Hello All.
Jake - I am aware of the competency levels when using Access equipment, but highlighted that a Tube &Fitting Scaff can not erect a Ally Tower due to lack of PASMA. The erection process is similar.
In regards would the PASMA course teach the Advanced Scaff anything - Not really - They will treat it as a Day out payed for by the company.
achrn - Being a Advanced Scaffolder to trade myself - I think I would know to raise the Outriggers before movement. And the Normal Guy off the comment is just a expression to a Non-Scaff.

Agreed, but I'd still go with not RIDDOR D.O.

I haven't seen any evidence of the height of the tower on this thread, Ron but if it was higher than 5m, i thought you had to report it.

Tigers et al,
Assuming that the tower is an Aluminium Mobile Tower then for most the maximum recommended height for moving is either 2.5 times the length of the smallest part of the base (including outriggers or stabilisers) or 4 metres overall height. Additionally you should not move a tower in winds of 17mph or greater. Though you will need to check with the manufacturer.
This would therefore almost certainly exclude the over 5 M for RIDDOR.
Not sure I would report it under a DO either, however I would carry out a thorough investigation! IMHO if the tower did not exceed the recommended maximum height, was only being moved using manual effort and did not have any materials or persons on it I find it difficult to understand how it toppled, even if one of the wheels did bog it would take a lot of effort before gravity took over.
Regards
Clive
