Asbestos Project Designer Practice Test

Classification of asbestos work tasks is based on the type of material and the disturbance involved. Class II covers removal of asbestos-containing materials that are part of building components but are not thermal systems or spray-on surfacing. Removing asbestos-containing wallboard fits this because wallboard is a building component and the work is removing the material that contains asbestos, not dealing with thermal insulation or sprayed surfacing. In contrast, taking out thermal system insulation involves materials used on piping or equipment heated or cooled by a system, which is Class I. Repairing asbestos-containing pipe is a repair or maintenance task on ACM in place, which is Class III rather than a full removal. Maintenance on non-asbestos materials would not involve ACM at all. So, removing asbestos-containing wallboard is the correct example for Class II work.
