Paint storage and mixing in same area as transformer?

[jlhmaint]

I know that code clearance for a transformer and panel is 3'I believe, don't have NEC with me. But the question is people at our shop want to move the painters stuff into an area were there is a transformer and two panel box's 120 and 480, the area is open and by the maint dept. My question is how far according to codes do the paint cabinets and the bench were the painter will be using thinners and such have to be from the electrical items i have stated.
