Corner Test is performed on walls of what height?

• A. 15 Foot Walls
• B. 25 Foot Walls
• C. 35 Foot Walls
• D. 45 Foot Walls

Answer: (B)

The Corner Test evaluates how flames and smoke behave around a wall corner in a typical two-story building. The height chosen for this test is 25 feet because it represents a common wall height you’d encounter in standard residential or small commercial structures used in training and field assessments. Using 25-foot walls lets you observe how fire moves around a corner, how smoke layers, and how ceiling interactions influence corner ignition in realistic conditions. A shorter wall, like 15 feet, wouldn’t reveal upper-level corner behavior, while taller heights such as 35 or 45 feet correspond to high-rise scenarios outside the usual Fire Inspector 1 scope, so they aren’t used for this standard test.
