I agree it is a maze in there. The x marks were done by me to indicate which rooms we had investigated for asbestos, colour changes were because my spray can ran out (theres green and yellow too). The complex IS FULL of asbestos but most areas should be safe for explorers, just dont go in any sub-floor ducts. The asbestos there has been disturbed by somebody 'salvaging' the copper pipes and is heavily contaminated. It is a wonderful site and I wouldnt like to see anyone regret exploring it in later life.....

If you've been there Iain, how do you explain the numbers sprayed everywhere too? I spent 2 months everyday doing an intrusive asbestos survey (hence all the sledgehammer holes everywhere) No site plans were available so we marked each room off as we did it. The numbers indicate asbestos sample points.....trust me its bad for your health in there....

Your all wrong it was me who did the x's and all the damage too during some survey work. We were looking for asbestos....I'd advise you all NEVER set foot in there.....
