But looking at it from kurnal's perspective, Civvy, I think you are blanketting all building users as incapable of looking after their own fire safety matters whilst you look upon yourself as having a uniquely high capability in such matters. Maybe, just maybe, a building user might be capable of taking all the fire precautionary measures that you yourself would take and maybe they can document it so that others, a fire risk assessor for example, can see the high standards they attain. I think this is where your logic and kurnal's coincide to illustrate that the thumbturn solution should not be prescribed universally. Universal application of any prescribed solution will often be an injustice for the better, more fire safety conscious people out there.
