Certified Fire Protection Specialist (CFPS) — Question 31

During which stage of a fire would the heat release likely to be controlled by the fuel package size and geometry (i.e. the surface area likely to burn)?

Answer options

• A. Incipient Stage
• B. Growth Stage
• C. Steady-state Stage
• D. Decay Stage

Correct answer: B

Explanation

The Growth Stage is when the fire spreads and intensifies, and the heat release is significantly influenced by the fuel's size and surface area. In contrast, the Incipient Stage involves initial combustion, the Steady-state Stage sees a stable fire behavior, and the Decay Stage marks a decline in heat release as fuel is consumed.
