Firefighters will risk their lives a little and a calculated man to rescue sable property
Firefighters will not risk their lives at all for lives or property that is already lost
Fast water durations can be short as
Five seconds of straight stream water NOT
What knocks down the fire and takes the developing thermal energy away with the slowing down rapidfire growth
fast water( known as resetting the fire)
What is like taking the energy of a fire and a fully developed stage and knocking it down to the energy put out by a fire in the growth stage
Resetting the fire
More than likely, the fire department shows up and what stage of the fire ‘’’’ OR RIGHT AFTER IT ‘’’’’
Growth stage or right after the room is flashed temperatures can range from 500 at the Floor 1500 at the ceiling and certainly over 500 and the fire room
There is many differences in opinion about temperatures in the Decay state fire but we can say generally that it’s between
200 and 300° or less than 500° NOT
Considerable pain registers on human skin at
111° p. 273 NOT
Burns occur at
118° NOT
Second-degree burns occur at
131° N OT
Pain receptor nerves become numb at
140° NOT
Human tissue is destroyed on contact at
162° NOT
The smoke of a decayed fire contains toxic levels of:
CM
HC
B
A
Carbon monoxide
Hydrogen Cyanide
Benzene
acrolien
The national Institute for occupational safety health lists the IDLH for acrolein at ‘’ ppm
2 ppm NOT
IDL H for Carmen monoxide is ‘’ PPM.. At ‘’’ ppm CO can run a person unconscious in 2 to 3 breaths and death can occur in less than three minutes
1200 ppm NOT
12,000 ppm
IDLH for hydrogen cyaniden is ‘’ ppm and its ‘’ times more toxic than Carbon monoxide..
50 ppm and it is 35 times more toxic than CO p. 274 NOT
Water application should come before
Ventilation and search
If ventilation is followed by water application from the attack crew, the flow path does not intensify the fire in front of the interior search team. This is referred to you as what kind of attack ?
Coordinated fire attack
What’’’ frequently indicate a confirmed fire:
Across from
At the rear of
Next-door to
Near the intersection of
Numerous calls p. 275
phrases
If firefighters enter a room to perform search and extremely high temperatures force them to crawl to tolerate the heat and smoke. This is a warning sign that.
Flashover is imminent
Roll over is also a sign that
Flashover is coming
What is your last warning before flashover occurs?
Rollover p. 278
There are four self limiting ‘’’ search tactics what are they?
From the door Yell “fire department anyone here” use your light and Tic to scan
Behind the door with your tool, then sweep out in front of you
Do not enter the room beyond the point of no return(5-6 ft)
An extreme heat conditions on upper floors, search the floor area below the windows from the ladder by reaching over the windowsills
defensive
The point of no return is estimated to be how far from the door
5 to 6 feet p. 279 NOT
Working in an IDLH area you have to abide by the two in two out rule. The two out firefighters should not stand around waiting for a Mayday call to occur . What should they be doing?
360° size up
Locating additional access points
Determining if there’s a basement deter what size ground ladders are needed around the perimeter
