Combustibility describes what?

Combustibility describes what?

• A. Material's ability to catch fire and burn
• B. Heat Release Rate
• C. Dry Floor Area
• D. Fire Suppression

Answer: (A)

Combustibility is the property of a material to ignite and burn when exposed to heat or flame. It describes how readily a material will catch fire and sustain combustion, i.e., its role as fuel for a fire. This is different from how much heat the fire releases (the heat release rate) and is not about floor area or fire suppression systems. In practice, combustible materials contribute to the fuel load and flame growth, while noncombustible materials do not. Wood is a common example of a combustible material, whereas concrete is typically noncombustible.
