Be brief

Concise

100

This is the most constant of the three fire environment components

Topography

100

Lower RH, Higher temp, less fuel loading, primarily Grass and Shrub fuel types, and snowmelt dates are earlier.

South/ South West Aspect

100

Characteristics

Moisture

Temperature

Three factors of the fire enviroment that involve fuels

100

Topgraphy, Fuels, and Weather

What is the Fire Behaivor Triangle?

200

Be unmistakeable in your message

Clarity

200

One factor that affects rate of spread

Wind speed

Steepness of slope

Changes in fuel type

200

Higher RH, Lower temps, Heavier fuel loading, Primarily Timber and woodland fuel types, snow melt dates are later.

North/ North East Aspect

200

Ground

Surface

Aeriel

Fuel levels
200

This atmospheric layer is where almost all weather occurs within

What is the troposphere?

300

Self-assurance in information you are sharing

Confidence

300

Ground fuel is heated by...

Conduction and radiation

300

Preheating of fuels due to convective and radiative heat and smoke. Fire behavior, ROS, and spotting can decrease or increase as the fire reaches a ridgetop and encounters opposing upslope winds.

Upslope Fire Behavior

300

Physical and chemical

Catagory of fuel characteristics that remain constant

300
The highest daily temperatures occurs roughly _________ after solar moon?

What is 2 to 4 hours ?

400

Handle your voice inflection

Control

400

Rate of heat released per foot of fire front per second

Fireline intensity

400

slower creeping backing fire, can increase with afternoon/ evening changes in wind direction. Fire Behavior and ROS may increase as the fire interacts with a slope reversal at the bottom.

Downslope Fire behavior

400

Grass

Shrub

Timber Litter

Slash

Four major fuel groups

400
"keep informed on fire weather conditions and forecasts"

What is the #1 firefighting order?

500

Practice speaking on the radio to develop skills

Capability

500

A state of the atmosphere in which the vertical distribution of temperature is such that an air particle will resist vertical displacement from its level

Stability

500

Canyon walls that come together in a box funnels air and smoke like a wood stove, increasing fire behavior and spotting

The Chimney Effect in Canyon Topography

500

ROS 18 TO 75 ch/hr

Shrub fire behavior characteristics

500

Too much of these gases, and the Earth would become unbearably hot

What are greenhouse gases ?
