Which floor plan design uses exit doors that lead from each room to a dirty corridor that wraps around the floor plan?

• A. Single-corridor
• B. Two-corridor
• C. Three-corridor
• D. Mixed

Answer: (C)

In this kind of facility design, controlling how people and materials move to keep clean areas separate from dirty work is essential. A dirty corridor that wraps around the floor plan provides a dedicated path for exits from each room, so staff can move out of rooms into a clearly defined dirty flow without passing through other spaces that should stay clean. Having three corridors allows the layout to establish a distinct dirty route around the perimeter while still providing separate pathways for other traffic, reducing the chance of cross-contamination and backtracking. A single corridor would force all traffic through one shared path, increasing risk; a two-corridor setup can separate clean and dirty but may not offer the looping, room-to-dirty-exit arrangement described. This three-corridor configuration best supports a unidirectional, wrap-around dirty flow from every room.
