Red Card Fire Suppression Techniques 5

Question 1

What is the purpose of a 'burnout' operation during wildland fire suppression?

Accepted Answer

Burning fuel between the control line and the fire to widen the black

Answer

A burnout intentionally burns fuel between an established control line and the approaching fire, strengthening the line by eliminating available fuel.

Question 2

Which condition makes a direct attack on the fire's head most appropriate?

Accepted Answer

Low-intensity fire in accessible, flat terrain

Answer

Direct attack on a fire's head is safest and most effective when fire intensity is low and terrain is accessible, allowing crews to work close to the flames.

Question 3

What is the main risk of using foam concentrate improperly on a wildland fire?

Accepted Answer

Incorrect dilution ratios reduce effectiveness or can damage equipment

Answer

Foam must be mixed at correct concentration ratios; too little reduces fire-knockdown effectiveness while too much can waste resources and clog nozzles or equipment.

Question 4

What is the significance of the 30/30/30 rule in wildland fire behavior and suppression planning?

Accepted Answer

30 mph wind, 30% relative humidity, 30-degree slope — high danger conditions requiring extreme caution

Answer

The 30/30/30 rule identifies extreme fire danger: wind speeds of 30 mph or more, relative humidity at 30% or below, and slopes of 30 degrees or steeper.

Question 5

During a flanking attack, crews work along which part of the fire?

Accepted Answer

The sides (flanks) parallel to fire spread direction

Answer

Flanking attack involves constructing control lines along the sides of the fire, working from the heel toward the head to reduce the fire's width and contain spread.
