Our facility is classified as Class 2 Div 2, however we have a small (12x8) room inside the facility that is used for milling of pastilles into a powder. The pastilles enter through piping, and leave via piping - thus under normal conditions, no material is visible in the room.
I'm planning on adding some instrumentation to this room, and am unsure whether I am limited by the Class 2 Div 2 regulations.
Is it possible to have an overall Class 2 Div 2 rating in a building with a room inside this area not being confined to this rating?
