Materials suitable for the encapsulation of woodwork include: <br /> • plastic <br /> • metal <br /> • wood <br /> Materials used to encapsulate should be firmly nailed, cemented, or glued in plat <br /> seams must be well caulked and sealed. The worker should be aware that lead dust <br /> might be generated from processes such as driving nails and drilling. Encapsulatic <br /> does not remove lead paint from the house; rather, it makes the paint inaccessible <br /> the residents. Therefore, encapsulated surfaces must be maintained over time by <br /> caulking and repairing, as needed, so that lead paint (or dust) remains inaccessible. <br /> Removal <br /> Since all the methods used to remove lead paint are extremely hazardous, pair <br /> removal should be considered only if replacement and encapsulation are nc <br /> feasible. Off-site paint removal is preferred. On-site removal of paint is the most <br /> dangerous abatement method, a:--I requires attention :.) proper containmen <br /> disposal procedures, and worker saiety (including respirator-: protection). Be awa: <br /> that people can unknowingly be exposed to lead paint in the course of common <br /> home renovation projects, and are at risk of lead poisoning. <br /> Methods of Removal: <br /> • Off-site paint removal <br /> • On-site paint removal <br /> Off-site paint removal <br /> • Off-site chemical stripping is recom.—nended when it is desirable <br /> restore old decorative Trim, :voiding and doors. The paint is -emove <br /> by placing the item in a dipping tank. There is some question as to <br /> whether this technique removes lead suificientiv. <br /> On-site rain: removal <br /> • Caustic striders, such as 'Peel A,,vav' may be effective on som <br /> surfaces. This method involves aucivinz a paste to the surface, pias:.; <br /> a sheet of paper over the area, and waiting 21 '8 hours for the paste to <br /> dry. In theory, the paint peeis off when the paper is peeled orf. On <br /> problem is that as theus <br /> paste dries, a fine lead dt is seated at _,e edges. <br /> Another problem is that stripped surfaces must be rinsed and acidified <br /> to remove the residue and 'ring the vH down, so that new paint wii <br /> adhere to the surface.
