1 keep informed on fire weather conditions and forecasts
2 know what your fire is doing at all times
3 base all actions on current and expected behavior of the fire
What are fire orders 4–6

Fight fire aggressively having provided for safety first
What are the common denominator’s on fires that involve a fatality or a near miss
Small fires innocent appearance light fuels uphill runs Change of wind turbulence
The fire burning on level ground will spread twice as fast at what percent slope
From level ground to 30% it will double from 30% to 55% it will double again
What is one of the most reliable safety zones
The black
When our firefighters exposed to the most toxic smoke on a wildland incident
During mop up when the fire is smoldering
What is a snag
A dead tree just waiting for it’s time to fall
What is a widow maker
Dead limb hanging in a tree that may fall when it is cut or dislodged or by a drop from aircraft
Which weather factor has the greatest impact on fire behavior
Wind
What are the four types of winds
1 General reported on daily fire weather
2 local
3 surface measured 20’ above ground
4 mid flame greatest impact on fire
Wind direction is determined by what
Where the wind is coming from not where it is going
What is the official name of the Santa Ana wind
Foehn winds or gravity wind
What happens when Santa Ana winds reach the coastline
They began to subside. Marine on Shorewinds battle with Santa Ana winds for supremacy and can rapidly change 180° in direction
Wind direction is determined by what
Where the wind is coming from not where it is going
What are signs of unstable air
Gusty winds
good visibility and
clouds growing vertically and
dust devils
At what relative humidity will fires burn freely
30% or below
What relative humidity is fired and her critical and extreme fire behavior possible
10% or below
For every 20° increase in temperature relative humidity drops how
By one half
What does LACES stand for
Lookouts awareness communications escape routes safety zones
What are for situations that will worsen a snag a dead tree problem
Working in the forest and a strong wind blows
working on steep slopes
working at night
working in diseased or bug kill area
Why is smoke so dangerous near power lines
Smoke is predominantly carbon and carbon is a good conductor of electricity so if it is thick enough smoke electrical energy will find a path to ground
