The encasement/enclosure of existing ACM, PACM or asbestos material shall be conducted in accordance with the following:

(a) Regulated abatement work area preparation. The regulated abatement work area shall be pre-cleaned, isolated and negative air established in accordance with Subpart 56-7 of this Part.

(b) Use of amended water. Areas that may be disturbed during the installation of hangers or other support and framing materials for the enclosure shall be sprayed with amended water. These areas shall be kept damp to reduce airborne asbestos concentrations.

(c) Loose and hanging asbestos material. Loose or hanging ACM, PACM or asbestos material shall be removed in accordance with the requirements of section 56-8.4 of this Subpart.

After installation of hangers, brackets or other encasement/enclosure supports, and before installation of encasement/enclosure sheathing material, damaged areas of fireproofing and thermal insulation shall be repaired using a non-asbestos material as per section 56-7.2 of this Part. Surfaces shall be prepared and replacement material applied in accordance with manufacturer's recommendation.

(f) Utility maintenance. Utilities shall be lowered as necessary and reinstalled in a manner which allows proper utilization, and does not disturb the integrity of the encasements/enclosures. Utility maintenance shall not require the encasements/enclosures to be opened or disturbed.

(g) Ducts. Ducts insulated with ACM, PACM or asbestos material shall not be encased or enclosed.

(h) Air plenums. ACM, PACM or asbestos material-insulated air plenums, which are not readily accessible for inspection, shall not be encased or enclosed.
