Thank you for all your comments.
It now seems some time ago but I thought I'd let you know how I'd got on!!
In all honesty whilst sat waiting for my 'performance'!! All I could think was - swap me all those kids for the same amount of Construction Guys ANYDAY!!

And of course please god do not let any expletives slip out

!!!
So as 9.30 arrived I sat on my miniture chair at the front of the hall as they all filed in (whispering and pointing 'who's that?' obviously!!) I dont think I had ever before realised there was such a massive age gap in Primary Schools!! At the front I had what looked to be a selection of children whih looked to be barely out of nappies!! Whilst up the back kids who looked about 30!!
The PPE went down a storm!! It was a brilliant and fun way of very basically conveying that if workers on Construction Sites have to wear all this protective equipment then it obviously isnt a safe place to be!! The signs were also very effective.
But if I have one piece of advice - questions are the future!! They loved it - hands shot up left right and centre for everything I asked!! And yes we may have a certian 'Bob' to thank for an advanced knowledge of site equipment!!! I nearly fell over backwards when I received 'Architect' as a response to 'who may work on a construction site' I didnt push the lack of validity of the comment
Whilst I appreciate some comments from you - I didnt really fancy explaining the Hierarchy of controls to 350 kids- one of which had forgotten to put on one of his plimsolls!!

Had it have been a more targetted approach then it would have been a great angle to go from with the older kids but dont think it wouldve suited the overall scenario!! After all I was hardly advocating they all go out and get their own PPE - just to stay away from sites whilst opening the doors of communication for kids to ask questions and get information about site without the need to come and have a look for themselves!! - which ultimately I believe fulfils the message I was asked to deliver!!
Overall it was a great experience and I really enjoyed it - personally Ive taken loads from it - bring on the next one!!!
