I’m looking at practice exam 1, case study 2, question 4:
The client has requested to change a storage room next to the exhibition hall (space 1-B) from pottery storage to cloth and fiber storage.
What is the new fire separation requirement for wall C?
My reading of the scenario is that the storage room, now classified as S-1, is accessory to the main occupancy, which I saw as A-3. I see that Table 508.4 shows a 1hr separation requirement between S-1 and A-3, but since I thought of the storage room as an accessory space, I assumed no separation would be required (508.2.4). It also appears that the aggregate square footage of storage rooms would be less than 10% of the floor area, meeting the requirements for 508.2.3.
In this scenario, why is the storage room not considered accessory to the main occupancy? Or…what is incorrect about my interpretation of the scenario?
