4761.2630 METHODS FOR REMOVING INTACT BUILDING COMPONENTS.

Subpart 1.

Applicability; general requirements.

The methods in this part must be used when performing lead hazard reduction to remove intact building components with intact lead-based paint. The removal methods must not disturb the paint or create paint chips or dust. Removing intact building components includes, but is not limited to, removing only a door or window sash from a door or window frame. All work must be completed in one working day.

Subp. 2.

Access required.

A person must allow the commissioner to have access to a work site, according to Minnesota Statutes, section 144.99, subdivision 2, while the person performs regulated lead work.

Subp. 3.

Work area preparation.

Before lead hazard reduction begins, the floor or ground surface must be cleaned using a vacuum with a HEPA filter to remove all visible paint chips that are present beneath the affected work surface and extending at least five feet beyond the affected surface in all directions.

Subp. 4.

Residents.

If residents remain in the residence while work is ongoing, the residents must be provided with lead-safe passage to a bathroom, at least one living area, and an entry and egress route. Unless actually performing lead hazard reduction, residents must not be allowed in the work area until all work is completed, no visible dust or debris remains in the work area, the clearance inspection is passed, and clearance dust samples are collected. The residents must be informed to avoid the work area until clearance results are below the standards under part 4761.2510, subpart 2.

Subp. 5.

Warning signs and barriers.

A.

Warning signs as required under part 4761.2615, item F, must be placed at the entry to the rooms or work areas where lead hazard reduction is actually occurring.

B.

Temporary fencing or barrier tape must be erected at a ten-foot perimeter around an exterior work area to keep out unauthorized persons. The barrier distance may be less if the distance to an adjacent building or sidewalk is less than ten feet.

Subp. 6.

Decontamination procedures.

A.

The certified lead firm, lead supervisor, or property owner performing lead hazard reduction must provide proper washing facilities for workers to thoroughly wash hands, face, and other exposed body surfaces.

B.

If existing facilities are used at the work site to decontaminate, the certified lead firm, lead supervisor, or property owner must:

(1)

provide workers with soap and disposable towels; and

(2)

clean the existing facility until no visible dust, dirt, or debris remains each day before leaving the site.

Subp. 7.

Cleaning procedures and inspection.

When lead hazard reduction is completed, the certified lead firm, lead supervisor, or property owner must:

A.

inspect all work surfaces where lead hazard reduction was conducted and visually determine that no suspect lead dust or debris remains in the work area;

B.

clean all surfaces within the work area using a vacuum with a HEPA filter or using any other EPA-documented methodology under part 4761.2000, subpart 15, item K, and extend the cleaning beyond the perimeter of the work area if visible dust and debris exists from the lead hazard reduction;

C.

clean all floors and ground surfaces in adjacent areas that were used for pathways to the work area and any areas used to store equipment and waste materials using a vacuum with a HEPA filter;

D.

visually reinspect all areas referenced in items A to C. If visible dust or debris remains, the cleaning procedures required under items B and C must be repeated; and

E.

conduct clearance inspections according to part 4761.2670.
