Coating on process equipment applied onsite

Even though industrial process equipment typically is furnished by the owner or tenant and not part of the normal construction scope, I believe that IEQc4.2 VOC limits still apply. Since the painting occurs onsite and inside the building during the construction period, the paint must meet SCAQMD or CARB VOC limits. Furthermore, SCAQMD-1113-2004 & CARB-2007-SCM each say that they cover coatings for “fixed stationary tools” that are accessory to a building. I think that this includes equipment such as you describe. Classify the paint by comparing its characteristics to SCAQMD & CARB definitions. If it contains metal flakes, the paint may be a Metallic Pigmented Coating with a VOC limit of 450g/L. Otherwise, if it is anticorrosive, it may be an Industrial Maintenance or Anti-Corrosive paint limited to 250g/L VOC. If the paint exceeds the prescribed VOC limit, a budget calculation may become necessary. In any case, if the equipment installers do the painting, make sure that they are bound by the project’s IAQ Management Plan and that they use precautions to avoid fouling IEQc3 pre-occupancy IAQ tests.
