Hospital intake vents

[jlpressure]

Im giving price to wash 3 story hospital I do work for. They have the large air intake vents in a row on each floor, the vents are approx 15X20 ? ea

anybody do this work and how could I protect these vents so the building wash mix and or fumes dont get in the vents. Any good ideas please

Thanks
Jeff

what ever you do dont let your chem fumes get sucked in them. i would just use water around them and talk to the person who gets the proposal about it. I did a bid for a big hospital around here and that was one of the main concerns.
