Which statement best describes how NFPA 101 treats mixed occupancies in terms of separation?

• A. Shared egress corridors with unified occupancy classification.
• B. Unrestricted movement between spaces to minimize barriers.
• C. Fire barriers or compartmentalization to separate occupancies.
• D. Elimination of all doors between occupancies.

Answer: (C)

NFPA 101 protects occupants by requiring clear separation between different occupancies to prevent fire and smoke from spreading and to maintain safe egress. This separation is achieved through fire barriers or compartmentalization, which create protected, enclosed spaces that slow fire growth and limit exposure. Fire barriers are rated walls (and openings that are properly protected) that isolate occupancies, while other spaces may use fire partitions or similar rated assemblies to maintain appropriate separation. Shared corridors with a single occupancy classification, or allowing unrestricted movement between spaces, would defeat this protective separation and permit rapid fire and smoke spread. Eliminating doors between occupancies also removes the essential barrier that contains fire and protects occupants. Therefore, the best approach NFPA 101 prescribes is using fire barriers or compartmentalization to separate occupancies.
