Posted By lewes Personally I would say... As with any other Risk Assessment you would have to identify who is at risk and the likely hood of that occuring With the stilts I would say that the only person at harm is the plasterer themself but I suppose you would have to make sure they are competent in working on them and are competent in the work activity. Obviously other matters like overhead obstructions, clear floor areas etc will have to be identified but that would be part and parcel of the risk assessment. A place is ‘at height’ if a person could be injured falling from it, even if it is at (or below) ground level. Examples of working activities that are classified as working at height include: · Working on a flat roof · Erecting falsework and formwork · Working from a ladder · Working at ground level adjacent to an open excavation · Working on formwork within an excavation · Working near or adjacent to fragile materials Hope this helps
