cashin- a very infomative and educational piece of work my friend,and a large amount of effort has gone into it,maybe get it published and sell it to the nasc for their paperwork trail, the only thing i would like to say and i do appoligise if i've concluded wrong,as speed reading was never my forte,and without meaning to demean your work at all is your figures although proberbly accurate and recieved from other sources of research - like many others always talk of falls from height or deaths from height,( did i miss-read or miss something within the dissertation that could confirm that these were actual scaffolders and not other trades such as roofers,painters etc as they seem to be really high and hard to beleave -(this question has been asked as i beleave to the HSE several times to which both they are the NASC do not really know as the figures are never collated and all bunched together) as the surgested percentage would relate to virtually every other scaffolder knowing another who had died from a fall, and certainly put off potential scaffolders from entering the trade lolol............but once again congratulations on a excellent bit of work
