Business occupancies are normally divided into group areas and individual working spaces that have the indirect positive effect of:

• A. separating the occupancy into multiple use or incidental use spaces.
• B. creating high fire loads and restricting exit access for customers and clients.
• C. compartmentalizing space and separating it into fire and smoke zones.
• D. forgiving oxygen from the spaces and causing a fire to become ventilation-limited.

Answer: (C)

Dividing business occupancies into group areas and individual working spaces creates barriers that slow the spread of fire and smoke. Those barriers establish fire and smoke zones, so a fire starting in one space is contained long enough to protect occupants and give firefighters time to respond. This is achieved through fire-resistance-rated walls, doors, and floors that delineate compartments, plus proper smoke barriers and protected egress paths. By limiting how quickly heat and smoke travel between areas, occupants have safer egress routes and suppression efforts are more effective. The idea here isn’t about using spaces for multiple purposes or reducing oxygen; it’s about containment—keeping fire and smoke confined to a zone to improve safety and control.
