Define spotting and describe one mitigation tactic.

• A. Embers carried by wind start new fires ahead of the main fire; mitigate by creating defensible lines, spacing, and using water to suppress spots.
• B. A large explosion within the fire perimeter; mitigate by blaring sirens.
• C. Firefighters spotting from observation towers; mitigate by wearing helmets.
• D. A technique of dropping water only from aircraft; mitigate by staying on the ground.

Answer: (D)

Spotting is when embers or firebrands are carried by the wind ahead of the main fire and start new flames in fuels that are not yet burning. These spot fires can leap ahead and allow the wildfire to develop separate ignition points, making containment much harder, especially in windy or arid conditions with receptive fuels. One effective mitigation tactic is creating defensible lines and defensible space: reduce fuels around key areas, increase the spacing between fuel beds, and remove or isolate flammable material so that embers have less fuel to ignite and the main fire has fewer paths to spread. This approach helps slow or stop spot fires from taking hold and provides safer opportunities for suppression efforts to respond quickly. Additional measures, like deploying water or other suppression tactics to extinguish spots as soon as they glow, complement the defensible space work and reduce the chance of spot fires connecting to the main fire front.
