Where should the first due engine position on a townhouse fire?
The first engine typically pulls at least 2 houses past the involved units. If the truck is entering the block from the opposite direction then stop two houses short.
Page 19
Primary actions of the first due engine include:
Initial attack line.
Search as the line is advanced.
Page 19
Initial duties of the second due engine include:
Ensure a water supply
Ensure the first line is operational
Deploy the second line
Page 19
Initial duties of the 3rd due engine include:
Secondary water supply
Visual inspection of side charlie and report findings to command
Check for fire extension
Possible exposure line
Page 19
Initial duties of the 4th due engine include:
Complete water supply for 3rd engine if needed
R.I.T.
Page 19
Initial duties of the 1st due truck include:
Position in the most strategic location that will allow for rapid placement of ladders and entry into the structure.
Force entry
Conduct primary search
Perform coordinated ventilation
Page 19
Where should the first due truck position the turn table

Page 19

Ground ladders and truck operations in the rear.
Page 19

Page 19

Page 23
The second line should be of sufficient length to _____________.
Reach the location of the initial attack line or to be advanced to the area above the fire if required.
Page 24
Where would you position the second line in order to protect the crew searching above the fire.
At the base of the stairs on the fire floor.
Page 24
What are the two purposes for placing a line above the fire?
Protect the company doing a primary search
Extinguish vertical extension
Page 25
What is the max amount of hose lines that can be stretched through any one entrance into a building
Two
Page 25
The line above the fire should is the responsibility of which unit? How long should this line be?
2nd or 3rd engine
The line should be of sufficient length to reach the area above the fire and into the attic if required.
Page 25
What are the 5 different methods to attack an attic fire?
- Gaining access and placing a hose line at the level of the fire in the attic
- Hooking the ceiling and directing the stream from below into the attic area
- Placing a wide fog stream into an access hole if the fire has not self-vented and the does not have a ridge vent
- Access to the attic area by cutting an access through the gable end
- Distributor / Cellar nozzle deployed through a hole cut in the roof while the member is independently supported on a ladder or tower.
Pages 33 and 34

There are three general locations for turntable placement at a townhouse. They are:
In front of the involved unit (for Contents fire with aggressive interior attack)
In front of the upwind exposure (for attic fires)
In front of the most threatened exposure (for situations involving the expected use of master streams)
*The second truck should position in front of the next most severely exposed unit. If possible, both turntables should be able to rotate back to the original fire occupancy to assist with the completion of extinguishing the main body of fire.
Page 42
If the truck and rescue arrive at the same time, what will each units assignments generally be?

What two areas are generally considered to be the most critical areas to search?
Means of egress and sleeping areas
Page 43
