Back to what Scott said - the code will classify it based on combustibility/toxicity/reactivity. B or H-something ... the more hazardous the occupancy classification, the higher the fire-resistive occupancy separation that's required. If there's no rated separation and it's just a room designation, then the occupant isn't really allowed to store the nasty stuff in the compartment. But if it's one-hour or two-hour, then at least the architect was aware of the potential for H-occupancy and it should be protected as such. It's highly unlikely, but if there's a two-hour envelope around the room, assume the worst.

I just received this, this morning. Someone else did the design and installed it, now looking for justification for the AHJ.

Then I'd ask what's it it. If a Gilbert Chemistry Set array of stuff then it's really nothing. If more exciting stuff then....
