We are working on a project with a small engine shop located in a corner of a large highbay warehouse. I finally argued the architect into putting a fire-rated wall around the engine shop, pointing out that it falls under NFPA 30A repair garages, and gasoline could be spilled, making it a Division 2 area to 18" AFF.

They put a door from the shop into the warehouse. NFPA 30A states that areas adjacent to classified areas are non-hazardous if they are ventilated to 4 AC/HR. In such a warehouse, that would be a LOT of ventilation. Does this door trigger classifying the entire warehouse Div 2 to 18"? That seems kind of excessive, but it also looks like that is the letter of the code.
