pg 29
**narrow fog pattern**
73
When ___ are encountered and an exterior entrance is not present, the fire should be knocked down from outside the basement. This can be accomplished by:
* Applying a fire stream into the basement through a window opening,
* Removing the band board on the exterior
* Extend a window cut down an additional foot or two, the same band-board access point will be provided. This also creates another access/egress point which may be used later in the fire.

79
To assist in containing (an attic) fire and slow the lateral spread, early ___ should be considered.
pg 33
**roof ventilation**
80
Several methods have proven successful when it comes to \_\_\_.
* Gaining access and placing a hose line at the level of the fire into the attic **(This option is usually the most effective)**
* An attic ladder needs to get to the top floor early when the officer has suspicion that fire has entered the attic space
* When time is critical, consideration should be given to using available means/options of access to the attic until a ladder is available (use of a kitchen counter, dresser, bed, etc.)
* Hooking the ceiling and directing the stream from below into the attic area. **This method is not as efficient as the previous method of placing the hose stream at the level of the fire.**
* Placing a wide fog stream into an access hole **is an effective method when the fire has not self-vented and the roof does not have a ridge vent**. (Mass steam production.)
pg 33
**Attic Fires**

Keep in mind that with platform construction, the roof itself adds structural support to the top floor walls. **If the roof has burned away the walls will be inherently weakened.**
82
Another hazard associated with the well-involved attic fire is the collapse of \_\_\_.
pg 35
**the overhang (soffit)**
## Footnote
The exterior wall acts as a fulcrum. As the majority of the roof burns away the remaining overhang may collapse downward to the balconies or ground. Firefighters must be aware of the risk when operating on balconies, Towers, ladders or the ground below this collapse hazard area.
83
Most flat roofs don’t have the cubic feet or fire loading of the pitched roofs. Most of the earlier buildings have either 2” x 8” or 2” x 10” wood joists. When fire gets above the ceiling of the top floor, it will usually run in one or more bays (area between joists). This inherently ___ and provides time for crews to ____ and \_\_\_.
pg 36
**confines the fire and access and extinguish the fire.**
84
One attack line on the top floor is usually sufficient to handle a cockloft fire. The exception is when there is a significant void of several feet. Tactics for ___ would apply in those cases.
pg 37
**pitched roofs**
85
If a new gable-style roof has been placed over a flat roof, firefighters are faced with a multi- layered cockloft and attic fire within the same building.

* Via portable ladders.
* With a large caliber stream and the wind at the back of the crew.
pg 39
**personnel cannot make entry**
88
A ___ is a situation where the volume of fire is such that fire spread to adjoining exposures is a major concern.
pg 40
**large volume fire**
## Footnote
* It may be necessary for the first engine to perform a holding action or a quick knockdown on the townhouse of origin by using a master stream device or 2 1⁄2-inch hoseline.
* The next line shall be stretched into the most severely threatened exposure, most likely, downwind.
* The third engine is still responsible for rear coverage.
* In the situation where a heavy volume of fire is encountered in the townhouse of origin, it may be appropriate for the first arriving officer to address the attached exposures first.
89
In the case of the rear exterior exposure, stretch the line via the shortest route. However, if wind is a factor, consider stretching the line through the \_\_\_, ___ or \_\_\_. This adds protection for operating personnel with the wind being at their backs.
pg 41
**upwind, attached exposure, or around the upwind end of the row**
90
There are three general locations for ___ at townhouse fires. These are determined by degree of fire extension and location.
* If it is a contents fire with an aggressive interior attack, place the turntable in front of the involved unit
* If there is an attic fire, place the turntable in front of the upwind exposure.
* For a heavily involved situation that may require the use of elevated streams, the turntable of the first truck should be in front of the most threatened exposure. The second truck should be in front of the next most severely exposed unit
pg 42
**turntable placement**
91
Should the rescue squad arrive at the same time as the truck, the ___ will generally be assigned the task of entry and primary search, and the truck is responsible for ventilation and laddering.
pg 42
**rescue squad**
92
