Which material is described as noncombustible?

• A. Combustible Material
• B. Fire-Resistant Material
• C. Noncombustible Material
• D. Insulating Material

Answer: (C)

Noncombustible means a material will not ignite or support combustion under normal service conditions, and it won’t contribute fuel to a fire. This is why it’s the right choice for dryer exhaust components—the system handles heat and lint, and using noncombustible materials helps prevent fires. Fire-resistant materials resist burning but can still burn under enough heat or time, and combustible materials will ignite, while insulating materials aren’t defined by noncombustibility (they can be either combustible or noncombustible).
