Certified Fire Protection Specialist (CFPS) — Question 21

Fire burns in three dimensional space, with flames attaching to inclined surfaces leading to a number of observed behaviors. Flames from a fire burning in a channel inclined at 10° above the horizontal will behave in a manner similar to:

Answer options

• A. A pool fire
• B. A trench fire
• C. A wall fire
• D. A ceiling fire

Correct answer: C

Explanation

The correct answer is C, as flames in a channel inclined at 10° will behave like a wall fire due to the angle at which they rise and attach to vertical surfaces. The other options, such as A (pool fire), B (trench fire), and D (ceiling fire), do not replicate the same behavior of flames interacting with an inclined surface.
