What is spotting fire and how can its risk be reduced?

• A. A new fire started ahead of the main fire by embers; risk reduced by reducing ember production, establishing guards, and rapid detection.
• B. A small fire inside the main fire area used to control heat.
• C. A type of spark plug used in engines.
• D. A measure to increase smoke production.

Answer: (A)

Spotting fire is a new ignition that starts ahead of the main fire, carried by embers or firebrands that wind can loft over barriers. It can ignite fuels outside the current flame front, potentially outrunning suppression if not found early. To reduce spotting risk, focus on three things: cut down ember production by keeping fuels less prone to producing embers and by managing vegetation and moisture; establish and protect guards or firelines so embers cannot cross into unburned fuels; and ensure rapid detection with lookout posts, patrols, and quick reporting so spotting fires are found and addressed early. This helps explain why embers traveling ahead of the fire are the problem and why the measures directly target that risk. The other descriptions don’t describe a new fire started ahead of the main one, nor do they address reducing ember-driven spread.
