Question 1

What is the purpose of 'scarifying' the soil during mop-up operations?

Accepted Answer

Removing flammable duff and litter to expose mineral soil and cool hotspots

Answer

Scarifying means scraping away duff and organic material to expose mineral soil, which helps cool hotspots and eliminate smoldering fuel.

Question 2

Which scenario best illustrates a 'slopover,' a common suppression problem?

Accepted Answer

The fire jumps an established control line and starts burning outside the contained area

Answer

A slopover occurs when fire crosses a control line, typically due to embers, rolling debris, or incomplete line construction.

Question 3

During extended attack on a large fire, night operations may be used primarily because:

Accepted Answer

Lower temperatures and higher humidity typically reduce fire behavior, making conditions safer

Answer

At night, cooler temperatures and higher relative humidity typically reduce fire intensity, providing safer and more effective suppression conditions.

Question 4

A firefighter notices smoke coming from a stump 30 feet inside the black during mop-up. The correct action is to:

Accepted Answer

Fell the stump, dig out burning material, and extinguish with water or soil

Answer

Burning stumps must be felled, dug out completely, and thoroughly extinguished to prevent re-ignition and escape.

Question 5

In suppression operations, 'size-up' refers to:

Accepted Answer

The process of evaluating all factors that influence fire behavior and resource needs before acting

Answer

Size-up is the systematic evaluation of the fire situation—including fuels, weather, terrain, and available resources—to guide suppression decisions.
