Smoke and fire barriers are usually located on which plans?

• A. Life-safety
• B. Site
• C. Mechanical
• D. Structural

Answer: (A)

Smoke and fire barriers are life-safety features that define protected portions of a building to slow fire and smoke spread and to keep occupants safe during an evacuation. Because their purpose is to protect people and guide safe egress, these barriers are documented where life-safety considerations are planned, on life-safety drawings. These plans focus on exits, travel paths, and fire protection elements, including the locations and extents of barriers. They aren’t primarily shown on site plans, mechanical plans, or structural plans, which cover site layout, equipment, and building structure, respectively. So the best placement for these details is on life-safety plans.
