Red Card Hazard Identification & Assessment 5

Question 1

A 'Red Flag Warning' is issued when which combination of conditions is forecast?

Accepted Answer

Low relative humidity, high winds, and critically dry fuels

Answer

Red Flag Warnings are issued when critical fire weather conditions — typically low RH (≤15%), high winds (≥25 mph), and dry fuels — combine to create extreme fire danger.

Question 2

What makes a 'dead fuel' more hazardous than a 'live fuel' in fire behavior assessment?

Accepted Answer

Dead fuel moisture responds to atmospheric conditions and can reach critically low levels quickly

Answer

Dead fuels equilibrate with ambient temperature and humidity, drying to critically low moisture levels during hot, dry conditions, unlike live fuels which maintain higher moisture through metabolic processes.

Question 3

Why is the afternoon period (1300-1800 hours) typically the most hazardous time for wildland firefighting?

Accepted Answer

Temperature peaks and relative humidity reaches its daily minimum, maximizing fire danger

Answer

Afternoon hours see peak temperatures and minimum relative humidity, creating the driest, most volatile fuel conditions and highest fire behavior potential of the day.

Question 4

When evaluating a potential escape route, which factor is most critical to verify?

Accepted Answer

The route can be traveled fast enough to reach the safety zone before fire arrival

Answer

An escape route is only effective if it can be completed in time — firefighters must know their travel time and compare it to how quickly the fire can cut off their route.

Question 5

What type of hazard do 'snags' (standing dead trees) present during wildland fire suppression?

Accepted Answer

They may fall without warning, striking firefighters working near them

Answer

Snags have weakened root systems and structural integrity; fire can undercut their bases or weaken them further, causing them to fall unpredictably and strike firefighters.
