NFPMD's Exception to stretching 1st HL up int stairs - ANSWER When fire is actively endangering civilians
evacuating building via windows or FE and immediate exterior water application is needed to protect

NFPMDs Roof HL uses - ANSWER - SHOULD ONLY be used to:
,1) Prevent fire from extending past the trench
2) To protect exposures
3) To extinguish fire that cannot be reached from below, such as a cornice fire
Note: HL shouldn't be operated into vent holes from the roof as this decreases vent and nullifies action
of lines operating on top floor
NFPMD's How to Vent windows - ANSWER - Windows should be opened 2/3's from the top and 1/3 from
the bottom to allow heat and smoke to vent and cool air to enter the room.
- If there is a tolerable smoke condition and very little heat in the apartment and the windows cannot be
opened, they should be left intact after a search has been made

Conditions warranting exterior stream - ANSWER 1. Fire blocks building entry
2. Delayed forcible entry to building
3. Delayed forcible entry to fire area
4. No progress by interior hoselines
5. Wind-impacted conditions
6. Advanced cellar fire
7. Trapped occupant or member
8. Exterior fire between buildings
Exterior stream operation - ANSWER When conditions warrant AND there is a window or other opening
accessing the fire area READILY AVAILABLE
,1. Members inside the building should be notified that an exterior stream will be utilized and positioned
to a safe area prior to water application.
2. The nozzle should be fully opened and held steady to create a tight stream which minimizes air
entrainment. There should be no circular or whipping motion
3. The stream should be operated at a steep angle, by placing members as close to the structure as
possible.
4. The stream should aim the water towards the ceiling.
5. After applying water to the ceiling, the stream should be moved upward towards the top of the
window opening (the lintel) and operated for a few seconds off the lintel.
6. Exterior handlines should only be used as long as necessary to visually see improvement in the fire
conditions. Normally this is approximately 10 seconds
OLT cellar fire exception to 1st HL down int stairs - ANSWER When an exterior entrance exists, especially
in the front of the building, that entrance should be utilized if it provides the quickest access to the cellar
to extinguish the fire. The use of an exterior cellar entrance at an advanced cellar fire is frequently safer
and more efficient to initially attack the fire.
Note: If this is done the second hoseline should be stretched to the first floor to protect the public hall,
interior
stairs, and the first floor, allowing the occupants to leave the building, and the ladder company to
perform VES.

beams (25'), and the fact that the floors are not heavily loaded
NLT MOST COMMON roof - ANSWER Has the top floor ceiling several feet below the main roof beams.
Roof boards are fastened directly to the top of the roof beams. Sturdy roof.
Inverted Raised or Reversed roof - ANSWER The main roof beams are at the ceiling level and a
framework
is raised above these beams with the roof boards attached. This roof is normally springy, but it permits
the roof
to be pitched so that water will run off.
, Note: When there is a heavy body of fire in the cockloft, expect at least a partial collapse of the inverted
roof. Since the inverted roof is constructed of 2 x 4's, they will burn away faster than the main roof
beams and the roof section will come to rest on these beams
NLT Size of roof opening - ANSWER Approximately 3x6' coffin cut is RECOMMENDED.
Note: Two saws should be put into operation promptly to prevent lateral spread of fire in the cockloft

Trench cut dimensions - ANSWER - ATLEAST 3ft wide & cut from wall to wall or other suitable firestop

Trench Cut Principles - ANSWER - 1 or more can be used
- Defensive operation
- SHOULD be pre-cut but not opened until fire shows at inspection holes (two or more on fire side of
trench)
- MUST be properly located and cut wall to wall or other suitable firestop (NO FIREWALLS)
- IF first trench is doubtful retreat and start a 2nd trench at greater distance
Roof HL for trench cuts - ANSWER Charged line should be in position on the roof to protect personnel

motion to prevent fire from extending across the opening. Only after precautions are taken to prevent
injury to interior operating forces
