We have an exit enclosure that is rated as Class I Division I. My understanding of an accessible route and means of egress, is that it is a "safe" means of egress.
Can an accessible route have a Class I Division I (explosion hazardous classification), or does it need to be purged and pressurized according to Type X requirements?

I am dealing with an extremely small fire pump room with limited wall space for the controllers. The only available space to route some of the wet main piping will be directly above the fire pump and jockey pump controllers.
Do the requirements from NFPA 70 concerning dedicated electrical space apply to fire pump controllers and the fire pump piping?
