What is the purpose of a grid search pattern during mop-up operations?
Answer: To systematically cover every part of the assigned mop-up area without missing hotspots
A grid search ensures complete, systematic coverage of the mop-up area so that no hidden hotspots are overlooked by firefighters working in overlapping lanes.
How should a burning root system be treated during mop-up?
Answer: Trace and expose the root, then apply water and mix with soil until cool
Burning roots must be traced, exposed, and treated with water mixed into the soil to ensure the entire smoldering path is extinguished.
What is the recommended minimum depth for mop-up into the soil to extinguish subsurface burning?
Answer: 4 to 6 inches into mineral soil
Mop-up should typically reach 4 to 6 inches into mineral soil to ensure smoldering duff, roots, and organic material below the surface are fully extinguished.
What is the purpose of patrol operations after mop-up is declared complete?
Answer: To monitor previously mopped-up areas for re-ignition
Patrol after mop-up ensures that previously extinguished areas have not re-ignited due to wind, hidden hotspots, or subsurface fire that escaped initial treatment.
When approaching a burning stump during mop-up, what is the correct treatment procedure?
Answer: Bore holes into or break apart the stump, apply water, and mix until cool to the touch
Stumps often hold interior burning embers; boring or breaking them apart exposes the smoldering core so water and mixing can fully extinguish the heat.
During mop-up near a hazardous snag that cannot be safely felled, what is the first action a firefighter should take?
Answer: Establish escape routes and a safety zone before working nearby
Before working near any hazardous snag, firefighters must first identify and establish clear escape routes and a safety zone in case the snag falls unexpectedly.
Which S-130 principle applies when a firefighter discovers an unextinguished hotspot in an area already certified as mopped up?
Answer: Report it immediately to the supervisor and treat it
Any discovered hotspot must be immediately reported to the supervisor and treated, because even small unextinguished embers can cause the fire to re-establish.
