Lots of things to consider here before an assessment of the current situation can be made, for instance is this installation pipework or service pipework? You would also need to consider the size of pipework and the cross sectional area of the duct, type of material that has been used, is it continuously welded or screwed? Various regional differences might also apply in some circumstances. My first point of contact would be to get some advice from your local Building Standards office with regards to ventilation and protective shafts.
