Removal of small amounts of ACM that would fit into a single 60x60 inch glove bag or disposal bag may be classified as a Class III job.

13. Class IV Asbestos Work. Maintenance and custodial construction activities during which employees contact but do not disturb ACM and activities to clean up dust, waste and debris resulting from Class I, II, and III activities. This may include dusting surfaces where ACM waste and debris and accompanying dust exists and cleaning up loose ACM debris from TSI or surfacing ACM following construction.
