Certified Fire Protection Specialist (CFPS) — Question 45

Piloted ignition temperatures of solids are influenced by:

Answer options

• A. air movement, rate of heating, size and shape of fuel load.
• B. ambient air temperature, conductivity, and height of fuel load.
• C. air pressure, reactivity, and width of fuel load.
• D. composition, chemical changes, and size of fuel load.

Correct answer: A

Explanation

The correct answer is A because piloted ignition temperatures are directly affected by factors such as air movement, the rate at which heat is applied, and the physical characteristics of the fuel. Options B, C, and D include elements that may influence combustion in general but do not specifically address the factors that impact piloted ignition temperatures in solids.
