What is used to spread fire from one area to another?

• A. Trailers
• B. Water Hoses
• C. Fire Blankets
• D. Alarm Systems

Answer: (A)

Fire can spread to new areas mainly through embers (firebrands) carried by wind. These burning particles can travel ahead of the main fire and ignite fuels in unburned zones, creating spot fires that extend the overall affected area. This ember-driven spread explains how a fire jumps gaps and grows even when the main flame front isn’t directly touching new fuel. Tools like hoses, fire blankets, and alarm systems are for suppression, protection, or detection, not for spreading fire, so the core idea tested is understanding ember transport and ignition of new fuels.
