paint stirrer Hazard Classification ?

[Steviechia2]

We are wiring an auto body shop. They have a paint stirrer that is just an open metal shelve and has a motor that will stir the paint in a closed can.

Question: They will be using water based paints which I could not find any explosives warnings on the back of paint can. Would this be a classified area and what type?

The motors label says intrinsically safe circuit for use in CLASS 1 GROUP D HAZ LOCATIONS

If the paint is not flammable there is no classified area.

I can't imagine a motor ever being intrinsically safe. Sure it can be designed for use in classified areas, but I don't see how you could ever make it intrinsically safe. My understanding of intrinsically safe is that the device cannot create an arc with enough energy to ignite the flammable vapors under any conditions or use or misuse. I am sure I could abuse it in a way that would result in an arc with enough energy to ignite any the flammable vapors.

Is most automotive paint waterborne and nonflammable?

They may in fact use some waterborne paint, which may or may not be flammable(probably won't paint many cars with latex wall paint from Home Depot), but they almost certainly will use solvent borne paint. Most paint shops use air driven mixers. What about the rest of the electricals in the classified (if appropriate) areas?

That's what I was thinking. I am going to have the owner give me in writing that all they will be using is water borne paints just to play it safe.
Thanks

Might want to have the owner talk to his insurance company - they are likely the ones that will have the most impact on what it is classified as.
