Hazardous Location Boundary

[Phillip Underwood]

I am trying to determine what the boundary for a Class I, Division I, Group D application would be. I understand the requirements for being in this area and for passing into the area, but cannot find a firm definition of how to specify the physical location of this boundary. Any help is greatly appreciated.

You will find guidance in NFPA 497.
