What is a primary reason it is impractical to separate portions of a building for different occupancy classifications when intermingled?

• A. It would require applying multiple sets of fire protection requirements.
• B. It would eliminate the need for fire alarms.
• C. It would make emergency lighting unnecessary.
• D. It would simplify sprinkler design.

Answer: (A)

When occupancies are intermingled, the same space must meet the fire safety needs of multiple uses. Trying to separate portions into different occupancy classifications would force the design to apply multiple, and often conflicting, fire protection requirements within the same structure. That patchwork approach makes the building harder to design, inspect, and maintain and increases risk because protections must be harmonized to cover all occupancies. The other protections—alarms, emergency lighting, and sprinklers—still have to meet the applicable safety standards and are not automatically eliminated or made simpler by dividing the space. So the practical issue is the need to apply multiple sets of fire protection requirements.
