What can serve as a fire boundary?

• A. Any physical boundary
• B. Water barrier
• C. Fireproof barrier
• D. Clearance boundary

Answer: (A)

Fire boundary means a barrier that stops fire from crossing from one space to another. The essential idea is that the barrier creates a physical separation between compartments so heat, flames, and smoke can’t easily move past it, and it stays effective only if it remains intact and properly closed. Because of that, the broadest, most practical view is that any continuous physical barrier between spaces can serve as a fire boundary. It doesn’t have to be specially fireproof in every situation to act as a boundary; its job is to maintain separation, at least long enough to contain the fire. A water barrier isn’t a guaranteed fire boundary since it doesn’t provide a persistent structural separation. A fireproof barrier is a specific type of boundary, but the question targets what can serve as a boundary in principle, not just the most reinforced type. A clearance boundary isn’t a standard term for structural fire control.
