Mixer room for spray booth

[Wiredtight]

I have a customer who wants to install a receptacle in an enclosed mixer room for a spray booth. The spray booth is seperate from the mixer room. First question is can I install a rec/gfi and if I can then does it need to be explosion proof?

is the room classified as a hazardous location and if so what class and div???

That's my diliema. I'm not sure. They will be mixing and storing paint in this room. The spray booth is a class 1 div.1 but I'm not sure if the mixing room is the same.
