(OP)
Steel beams are undergoing a first coat application of a zinc based primers. What are some effective ways of controlling fugitive emissions of organic vapors ladden with zinc fine particles.
Thermoxidizers were not recommended by their distributors.

RE: Overspray of zinc based primers
The amount of pollutants derived from the over-spray of coatings can be reduced by using coatings that contain less of a pollutant of concern and/or by increasing the transfer efficiency (thereby decreasing over-spray) of the coating process.
Airless sprayers can be used as these typically have higher production rates, use less coating to achieve the same thickness, and generate less over-spray.
