what is your role in this e.g. are U the adviser, the supervisor or what?

Invictus, you cannot be expected to understand every work process you come across. It will be essential to do the assessment as a joint exercise with the team leader doing the work - assuming they know how to do the job that is!

Approach it logically - what can go wrong, how, who will be hurt, how badly and what is in place to stop it i.e. not any different from all other risk assessments.

If you have already specified the PPE, perhaps you have put the cart before the horse?

One immediate question on method has occurred to me: with the side panels removed, will there be sufficient structural strength remaining to support the glazed roof?

Just a thought

Not sure how big this greenhouse is, but normally sheets of glass will be layered one on top of the other working from the bottom to the top central ridge / apex. So if you will be working from the bottom edge of the roof will you be able to unhook the glass sheet ( assuming glass) from underneath as you will need to raise the sheet above slightly with all its weigh and the weight of all the other sheets above it. Hope that make sense.

A possible alternative would be to work from one end, perhaps. Then you will be able to remove the sheet at the apex first and not be in the way of falling sheets.

Your description of the work brought to mind the horror film the Omen with the sheets of glass -ouch. I think that was the film anyway.

First hit on google:
http://www.elloughton-gr...-dismantle-a-greenhouse. (I know it's lazy, but hey, it's how it is!).

However, David's point is the salient one - it should not be down to a safety adviser to determine safe ways of doing work, (or assessing risk) unless you are an expert on the topic yourself. And googling doesn't make you an expert.

On behalf of, and with agreement of, the relevant manager, get together with the people / supervisor and ASK them how they plan to do it. Discussion can then draw on any particular points which concern you from your research. David's tips are spot on. Be prepared to summarise the agreed method for them, as you are probably more adept at words. Get them to review your draft and agree/challenge as appropriate. When plan agreed, hand over to the manager for them to instruct workers that the plan is now a commitment to comply.
You aren't their line manager or supervisor.

listen to David & aud;

Additionally; if nobody in the co has any idea as to how** to dismantle the greenhouse the production managers may have to think outside of the box e.g. hire a large bulldozer and just flatten the building with that and pick up the pieces afterwards thus avoiding work at height

[**this lack of knowledge about how to do things is common practice in all areas as businesses just want business and worry [if they worry at all] about how things are done afterwards]

Down, and no injuries
