What could happen if building layout is not considered in fire protection design?

Considering the building layout is crucial in fire protection design because it directly influences the effectiveness of sprinkler systems and the safety of evacuation routes. If the layout is not properly evaluated, various obstructions may impair the performance of sprinkler systems. For instance, walls, partitions, or other structural elements could block the spray pattern of sprinklers, preventing them from adequately suppressing a fire. Additionally, poorly planned layouts can complicate evacuation routes, making it difficult for occupants to exit quickly and safely.

This comprehensive understanding of how building layout impacts both sprinkler functionality and evacuation processes emphasizes the importance of careful fire protection planning. In contrast, the other options do not directly relate to the negative consequences of neglecting the building layout in fire protection design.
