Draft paper prepared by ARCA for consideration and discussion at ALG Meeting, 3 November 2009. A Decontamination Unit (DCU) used for asbestos removal works is a potentially contaminated facility, acknowledged by the requirement for it to be air tested prior to removal from a site where it has been used in the decontamination process. Despite strict decontamination procedures, there may be a residual risk such that employees and others need to be warned.
