S-1 vs S-2 in fire separation

[SLO_Stu]

S-1 occupancies are noted as MODERATE hazardous and S-2 are noted as LOW. Yet in table 508.4 S-2 needs a fire wall between other occupancies where S-1 doesn't. What am I missing? Example (sprinklered bldg) S-1 next to M = NR, yet S-2 next to M = 1hr

thanks all

S2 is less hazardous than B for instance so you are protecting the brick storage from the paper in the office....Or using your M...the goods for sale....

As Steveray said your protecting the S2 from the other occupancies that have higher fire loads in general.

Let me clarify the question. I understand the reason for the separation the question is why is the S-2 have greater separation requirements than an higher S-1 hazardous occupancy?
