| 摘要： | The U.S. Army maintains a large inventory of buildings treated with lead-based paint (LBP). LBP abatement and disposal is problematic. The residual waste from LBP removal often contains enough lead to be considered a hazardous waste, thereby requiring special handling and disposal. Associated higher costs of worker protection and waste disposal prohibit the use of traditional paint removal methods for removing LBP. A recently developed proprietary product--Blastox (registered)--consists of a material, which, when added to a typical abrasive medium, creates an engineered abrasive that is suitable for removal of lead-based paint systems from most surfaces and that, when water is added, also chemically stabilizes the lead in the residual waste so that the waste does not exhibit the Resource Conservation and Recovery Act (RCRA) toxicity characteristic for lead. This investigation evaluated the performance and cost-effectiveness of using Blastox(registered) for removing LBP from wood and steel structures, and for stabilizing the residual waste material. Both laboratory and field evaluations confirmed the feasibility and cost-effectiveness of using Blastox to remove and stabilize LBP. |
