The Bridge Technical Community of Interest is a group of professionals (both AMPP members and nonmembers) that will include, owners, manufacturers, consultants, contractors and others who have come together to share and discuss issues affecting the bridge industry and new and emerging technology. Through the shared knowledge of this diverse group, both geographically and from varying viewpoints, information can be discussed about current issues for both the design phase and construction phase. This can include the selection of containment to surface preparation and materials, abrasives, coatings, solvents, etc. during the design phase and issues during the actual construction phase with the contractor’s submittals, means and methods. The sharing of knowledge on how to deal with structural issues that could be detrimental to the life of the newly applied system can be discussed along with new and emerging technologies and how they can be incorporated into bridge coatings to streamline those processes and possibly lower the overall costs.

Evaluation of Gas, Vapor, and Particulate Emissions Generated During a Demonstration of an Atmospheric Plasma Coating Removal Device at the Virginia Department of Transportation 

08-12-2025 09:24 AM

Atmospheric plasma coating removal is a new technology that facilitates the 
removal of organic coating systems from surfaces. The atmospheric plasma coating 
removal process is reported to release carbon dioxide, water vapor, and inorganic dusts 
at temperatures low enough to be removed from hot-work requirements (Yancey, 
Atmospheric Plasma Depainting, 2014). On August 29th, 2024, The Virginia Department 
of Transportation Central Office Environmental Division, in partnership with the Virginia 
Transportation Research Council, evaluated an atmospheric plasma coating removal 
demonstration conducted by Atmospheric Plasma Solutions, Inc. The purpose of the 
evaluation was to inform potential uses of the new technology by the Virginia 
Department of Transportation and to quantify potential occupational health and safety 
related hazards of the atmospheric plasma coating removal process. This research 
project presents the findings related to the occupational health and safety related 
hazards. Objectives of this research project included: 1) Identifying reactive oxygen and 
nitrogen containing gases and vapors created during atmospheric plasma coating 
removal during removal of coating systems, 2) Calculating the generation rates of 
gases, vapors, and particulates created during the atmospheric plasma coating removal 
process, 3) Characterizing the airborne particulate created during the atmospheric 
plasma coating removal process, 4) Documenting morphologic changes that may occur 
to inorganic constituents during atmospheric plasma coating removal; and 5) Identifying 
potential hazards and exposure concerns for workers using atmospheric plasma coating 
removal.
