Section 56-7.10 - Regulated abatement work area pre-cleaning

(a) Movable objects. Movable objects within the regulated abatement work area shall be precleaned using HEPA-filtered vacuum equipment and/or wet cleaning, and such objects shall be removed from the regulated abatement work area to an uncontaminated location. Upholstered furniture and drapes shall be HEPA-vacuumed twice before removal from the regulated abatement work area. Carpeting shall be HEPA-vacuumed twice and cleaned before removal from the regulated abatement work area. If disposed of as asbestos-contaminated waste material, cleaning of carpeting is not required. If carpeting is left in place, it shall be covered with 3/8 -inch thick plywood sheathing prior to required plasticizing.

(b) Fixed objects. Fixed objects and other items which are to remain within the regulated abatement work area shall be precleaned using HEPA-filtered vacuum equipment and/or wet cleaning methods. Such objects and items shall be enclosed with two layers of at least six mil fire-retardant plastic sheeting and sealed airtight with duct tape.

(c) Precleaning. The regulated abatement work area shall be cleaned using HEPA-filtered vacuum equipment or wet cleaning methods or both. Methods that raise dust, such as sweeping or vacuuming with non-HEPA-filtered equipment shall be prohibited. ACM, PACM or asbestos material shall not be disturbed during precleaning. Precleaning is intended for preparation work, not gross cleaning of visible asbestos debris such as disturbed ACM, PACM or asbestos material on floors or other work area surfaces. Precleaning shall be performed in the following order.

(1) Locations in which critical barriers and isolation barriers are to be installed shall be cleaned first using a HEPA-filtered vacuum and wet cleaning methods before the barriers are installed. After the critical barriers and isolation barriers are installed, the negative air ventilation units shall be started. Once the negative air ventilation units are operational, the remainder of the precleaning shall take place and area plasticization shall begin.
