Posted By Stuart Nagle Gary. I would have thought that you would have undertaken a H&S assessment of your contractors coming to work for you, and in addition, so far as asbestos is concerned, you will advise them of the location, restrictions, and permitted/prohibited work in any areas of/or containing asbestos identified in your asbestos register (if they need to enster such areas). If the above is carried out and recorded I see no reason to duplicate the information in the asbestos register itself, so long as your records can be compared and this is established by a link in the documents (i.e. there is a reference to the process/procedures in place that is auditable).
