Section 56-11.4 - Pre-demolition asbestos abatement projects

The following Phase II abatement procedure modifications shall apply for building/structures planned for demolition. All ACM, PACM or asbestos material must be removed from a building/ structure and the asbestos project complete, prior to commencement of demolition activities.

(a)Air sampling and analysis.

Air sampling and analysis on an asbestos projects conducted under this section shall be conducted in accordance with the requirements of Subpart 56-4 of this Part.

(b)Regulated abatement work area preparation.

Regulated abatement work area preparation shall be as per Subpart 56-7 of this Part, except as follows:

(1) Timing-removal of salvage. Objects that can be removed from the regulated abatement work area without disturbing friable ACM prior to beginning Phase II B abatement procedures shall be completed as follows. The removal of nonporous, movable or non-movable salvage shall occur after critical barriers, isolation barriers and decontamination enclosures are in place in that portion of the building or structure, and only after salvage has been wet-cleaned and HEPA-vacuumed.

(2) Floor, wall and ceiling plasticizing and sealing. All porous floor, wall and ceiling surfaces, except where abatement of ACM, PACM or asbestos material shall be performed on those specific surfaces, shall be covered with one layer of, at a minimum, six mil fire-retardant plastic sheeting. The floor shall be plasticized first, and its plastic sheeting shall extend up the walls a distance of at least 12 inches on all sides. The walls shall then be plasticized by applying plastic sheeting from the ceiling to the floor, overlapping the floor sheeting by at least 12 inches. Next, the ceiling shall be plasticized, overlapping the walls by at least 12 inches, to form a secure airtight seam. If the floor surface is not to be plasticized, it shall be made watertight. All seams in the plastic shall be sealed watertight and airtight.

(3) Suspended ceilings. Suspended ceiling tiles and T-grid components in proximity to friable ACM shall remain in place until the regulated abatement work area has been fully prepared in accordance with this section, and electrical and HVAC systems have been shut down. These potentially contaminated suspended ceiling components shall be removed at the completion of the remaining work area preparation, including establishment of negative air ventilation systems, prior to commencement of Phase II B activities. These removed ceiling components shall be bagged/containerized and disposed of as asbestos waste. Critical barriers shall be installed above the suspended ceiling as per section 56-7.11(a) of this Part, prior to the commencement of Phase II B abatement.

(4) Elevators. Elevators running through the regulated abatement work area shall conform to the following:

(i) The elevator door in the regulated abatement work area shall be enclosed per section 56-7.11(d) of this Part.

(ii) Elevators not remaining in use shall have the fuses removed and the power switch locked in the open position.

(iii) Elevator shafts shall not be used as waste chutes for asbestos waste material.

(iv) Elevators that remain in use shall conform to the additional procedures to minimize the piston effects.

(a) Elevator controls shall be modified to bypass the regulated abatement work area.

(b) A third (final) layer of polyethylene is to be duct taped airtight but with slack so as to form a larger perimeter diaphragm. Air leakage across the barrier shall be corrected upon discovery, and the elevator shaft shall be checked for airborne asbestos contamination. If contamination is found in this area, the entire affected area shall be wet-cleaned prior to continuing any other work.

(c) This system shall be smoke tested daily.

(c)Removal.

Removal of ACM, PACM and asbestos material shall proceed as per the requirements of Subpart 56-8 of this Part.

(d)Final cleaning and clearance procedures.

Final clean-up and clearance procedures for pre-demolition abatement shall comply with Subpart 56-9 of this Part, except that only two stages of cleaning (first and final) are to performed. Lockdown encapsulant use shall be consistent with section 56-9.1(b) of this Part.

(e)Final waste removal from the site.

The requirements of Subpart 56-10 of this Part shall apply, once all asbestos project regulated abatement work areas have been completed.
