The goal of the Corrosion Control Tool Kits for Effective Corrosion Removal and Surface Preparation project is to enhance surface preparations in order to improve coating adhesion to the substrate. The present practice of removing rust from Chemical Agent Resistant Coating (CARC) coated surfaces is to use a paint scraper, wire brush and grinder. The individual performing the removal must wear a Tyvek suit, full-face respirator, and other personal protection equipment and the individual also has to attend respirator training. The focus of the Army Corrosion Kits is to attempt to eliminate the need for the Tyvek suits, full-face respirators, and other personal protection equipment. The kits provide a way to collect the dust as it is being generated. The objective of the first echelon rust removal is to control or remove the corrosion and thereby eliminate the need for costly depot (second echelon) restoration. User friendly dust-less tools and HEPA (High Efficiency Particulate Air) filtered portable vacuums are used to help accomplish this, as well as minimize clean-up time and waste.
