(a) Methods of Hazard Reduction.
(1) Furnishings must be removed from each room or area as it is prepared for reduction. Those furnishings that cannot be removed must be covered with plastic and sealed with tape. Furnishings should be thoroughly cleaned to remove lead dust before returning them to a room that has undergone hazard reduction.
(2) Each area that is to be reduced shall be sealed with plastic and taped prior to hazard reduction in order to contain the reduction residue.
(3) Dry sanding, heat guns, the use of an open flame torch and chemical strippers containing methylene chloride are prohibited reduction techniques. Methylene chloride based strippers may be used, if necessary, in small quantities as a final touch-up.
(4) The entire floor of the work area shall be covered with plastic and all seams and edges secured with tape and staples.
(5) All reduced surfaces must be inspected within a reasonable time frame.
(b) Walls/Ceilings.
(1) If a defective area of a wall or ceiling is localized, only the defective area should be scraped and repaired to create a smooth surface. The entire wall or ceiling must then be repainted with a paint containing less than six one hundredths of one percent (0.06%) lead in the final dried state.
(2) If the walls or ceilings are determined by the Office to be suitable for repainting, covering with fiberglass, vinyl, sheetrock, and/or any type of paneling or other covering which seals the seams and edges will be satisfactory.
(c) Woodwork and woodtrim.
(1) Nonchewable surfaces. Approved methods of hazard reduction are wet scraping until smooth, replacement, covering with new wood and sealed and caulked seams, and/or paint removal using chemical strippers, which do not contain methylene chloride. Methylene chloride based strippers may be used, if necessary, in small quantities as final touch-up method. Off-site chemical stripping of woodwork and wood trim is also acceptable. All reduced surfaces must be repainted with paint containing less than six one hundredths of one percent (0.06%) lead in the final dried state.
(2) Chewable surfaces. Approved methods of hazard reduction are wet scraping, replacement, covering with new wood with sealed and caulked seams, and/or paint removal using chemical strippers may be used, if necessary, in small quantities as a final touch-up method. Off-site chemical stripping of woodwork and wood trim is also acceptable. All reduced surfaces must be repainted with paint containing less than six one hundredths of one percent (0.06%) lead in the final dry state.
(d) Floors. Coated with lead paint must be encapsulated using a quarter inch tempered hard board or plywood underlayment or vinyl tile or linoleum flooring. Upon written request from the owner, the Office may consider other appropriate means of reducing surfaces.
(e) Exterior. Approved methods are wet scraping, water blasting, or encapsulation. All reduced surfaces must be repainted with paint containing less than six one hundredths of one percent (0.06%) lead in the final dried state.
(f) All reduced surfaces must be inspected by the Office prior to the painting or coating of said surfaces.
(g) Clean-up.
(1) At the end of each work day, rooms or areas in which hazard reduction in complete shall be thoroughly cleaned in conformance with this section, or properly sealed from the remainder of the dwelling or secondary residence.
(2) Before unsealing each room or area, it should be thoroughly cleaned, inspected by the Office within a reasonable time frame, surface recoated and then cleaned again. Once a room has received clean-up it should not be reentered by the workers.
(3) In absence of a HEPA vacuum, two thorough washings using a strong detergent, as prescribed by the Office, with frequent changes of water, each followed by two additional treatments after repainting or coating, will be considered satisfactory.
(4) Use of an ordinary vacuum for clean-up of reduction debris is prohibited. Sweeping should be limited to preliminary cleanings only.
