User Guide and Specifications for Using Blastox(R) To Remove and Stabilize Lead-Based Paint
Abstract
The U.S. Army maintains a large inventory of buildings constructed before 1978, when the use of lead-based paint (LBP) was discontinued. The Army also owns more than 300 elevated water storage tanks and hundred of other steel structures that have been painted with red lead primers. Regardless of whether LBP has been applied to a substrate of steel or wood, LBP abatement and disposal is problematic. A recently developed proprietary product-Blastox(registered)consists of a material, which, its manufacturer's product literature calims, may be added at a 15 weight percent mixture to a typical abrasive medium to create an engineered abrasive suitable for sand-blasting lead-coating system from wood, steel, or concrete surfaces. The manufacturer also maintains that the additive chemically stabilizes the lead rendering the waste product nonhazardous. CERL's laboratory and field evaluations confirmed the feasibility of removing and stabilizing LBP in a one-step process. Abrasive blasting successfully removed the paint and the lead stabilizer immobilized the lead, allowing the waste to pass Environmental Protection Agency tests.
