In most cases this involves thermal insulation which has been in place for some time. Quite often there is doubt whether the material in question does, indeed, contain asbestos. Experience around the Construction Division has demonstrated that the only accurate way to make this determination is laboratory analysis of the material. In the event that your site is using a more subjective technique you may wish to consider use of a laboratory in planning future work, or assume that asbestos is involved and take appropriate precautions of wetting down, respiratory protection and restricted access to'the area.
