|

B) The initial attack lines should be shut down and the larger backup lines be placed into service. C) Master stream appliances should be immediately placed into service. D) The fire should be attacked using the initial attack lines from a different angle |
The initial attack lines should be shut down and the larger backup lines be placed into service. |
|
|

Utilizing a smaller hoseline will minimize the amount of water delivered into the building. |
|
|

__________________ are the Engine Company’s first line of defense.
|
Back–up lines are the Engine Company’s first line of defensse.
|
|
|
what is a back–up line?
|
It is an additional hose line used to re–inforce and protect personnel in the event that the initial attack line proves inadequate
|
|
|
Can back up lines be used for exposure coverage or to attack the fire at other positions?
why or why not? |
Back–up lines are not used for exposure coverage or to attack the fire at other positions. Rather, they are held in readiness to back up attack lines in the same general area when and if they are needed.
|
|
|
what is the general rule of thumb for the size of the back–up line that should be used?
|
*Back–up lines should have greater reach and carry more water than the initial attack lines. This means that, in general, back–up lines should be at least one size larger than initial attack lines.
|
|
|
When two 1–3/4” lines are used for initial attack, the back–up line should be a __________ hose.
|
When two 1–3/4” lines are used for initial attack, the back–up line should be a 2–1/2” hose.
|
|
|
A 2–1/2” attack line should always be backed up with a ______________hose line.
|
A 2–1/2” attack line should always be backed up with another 2–1/2” hose line.
|
|
|
If the 2–1/2” initial attack lines have spray nozzles the back–up lines should be equipped with _________________
|
If the 2–1/2” initial attack lines have spray nozzles the back–up lines should be equipped with smooth–bore tips.
|
|
|
*When an interior attack using 2–1/2” hose lines fail to control the fire, you should do what?
|
*When an interior attack using 2–1/2” hose lines fail to control the fire, back outall fire fighters and attack using master stream appliances. This will call for changing tactics from an offensive mode to a defensive mode
|
|
|
is it ok to give the back–up assignment to firefighters who have already been engaged in initial attack operations?
|
The back–up assignments must not be overlooked, nor should they be given to firefighters who have already been engaged in initial attack operations.
