the tower ladder is used for ventilation purposes on a flat roof? (4.1.2)
a. Axe and halligan tool
b. Six foot hook
c. Utility rope
d. Power saw
- C
- Operating on the roof of an unstable building is a very dangerous operation. Which one of
the following suggestions is incorrect when operating on these roofs from a tower ladder?
(4.2.2)
a. Keep the basket close to roof level and secure members with a utility rope. Do not engage
in prolonged operations
b. Use of a portable ladder laid flat on the roof will help distribute the weight of a member
over a greater area
c. If conditions permit place the basket on the roof and have members operate from the basket
d. When operating on taxpayers and similar structures with hanging ceilings, 10’ hooks or
portable ladders may be used to push down ceilings below roof openings, operating from the
basket
- A
4.2.2 When instability of the roof is suspected, exercise extreme caution:
A. Keep basket close to roof level. Secure members to basket with life saving
rope. Do not engage in prolonged operations.
B. Use portable ladder, laid flat on roof, to help distribute weight of
member(s) over a greater area.
C. If condition permits, place basket onto the roof and have members work
from the basket.
D. When operating on taxpayers and similar structures with hanging ceilings,
ten foot hooks or portable ladders may be used to push down ceilings
below roof openings, operating from basket.
- Two firefighters are preparing to operate from a tower ladder basket on a roof of
questionable stability. Prior to operating on the roof, the officer in charge of the operation insure
that the member on the roof was tied off to the basket via a bowline with a _____ foot loop,
which limits the member to a radius of not more than _____ feet from the basket ( 4.1.4)
a. 10 ft., 15 ft.
b. 5 ft., 10 ft.
c. 15 ft., 15 ft.
d. 15 ft., 10 ft.
- D
- Members of Ladder Company 153 are preparing to cut a hole in the roof of a peaked roof
private dwelling. In regard to cutting this type of roof from the tower ladder basket, these
members would be incorrect if they were to perform which action? (4.3)
a. The saw was started inside the basket and then help outside the basket until it was shut
down
b. The first cut was made parallel to the ridgepole
c. The size of the cut should be approximately 3’x 6’
d. The saw operator cuts with one foot on the roof and the other in the basket
- C
Note: The size of the cut will depend on the reach of the operator. He shall never
over-extend himself. Re-position basket if larger opening is necessary.
- Masonry walls can be breached utilizing power tools from the tower ladder basket. While
breaching a brick wall using the partner saw, two firefighters from a ladder company had the
following thoughts. In which one were they incorrect? (4.4)
a. They insure the saw had the correct blade, painted yellow
b. A triangular cut was made with the first and second cuts being made at the brickwork. The
apex of the triangle faced downward.
c. The third cut at the mortar joint may not be necessary. Brickwork may be loosened and
removed with hand tools
d. The opening should be large enough to insert the saw in order to cut the second course of
brick if necessary
- B
4.4 Breaching Walls
4.4.1 Exterior walls can be breached with power tools. Breaching may be necessary to
gain access for life saving or stream penetration. This is an arduous operation
requiring frequent relief of saw operator.
A. Power saw with proper blade is used for brick and concrete work.
B. Where necessary, electric or pneumatic hammers may be used for
breaching work from basket.
C. Cuts in brick walls should be triangular form with vertex angle upward to
prevent further collapse. (See Fig. 12)
D. 1st and 2nd cuts should be at brickwork since easiest cut is at mortar joint
and blade at this point will be worn. Cut at mortar joint may not be
necessary since bricks along this plane can be loosened and removed
easily with hand tools.
Note: Make opening large enough so saw can be inserted to cut inner wall
if necessary. Usually on two course brick wall the second course can be
remove by hand tools, or if heavy stream is to be used, by the stream
itself. Opening can also be enlarged by use of the stream. Frame building
shingles, siding, roof shingles and boards can also be removed by use of
the stream if fire conditions pre-empt structural damage
- The lieutenant of a tower ladder whose basket has double acting swinging gates responds to
a fire scene where the apparatus must be placed for rescue and removal. Which one of the
following would be an appropriate action for the lieutenant to direct members to take? (5.1)
a. Place the basket initially so that the top railing of the basket is level with the sill
b. Place the apparatus parallel with the building so that the pedestal is in line with the window
c. Place the basket directly on the roof if the roof has no parapet
d. Use the platforms “dead man” trigger handle to perform all delicate positioning operations
- C
5.1.5 Parapetless roofs can be safely approached by actually placing the basket directly
on the roof, if possible, especially when ice conditions are encountered, to effect
removal of persons trapped thereon.
- Ladder Company 19 is preparing to remove a seriously injured construction worker from
the roof of a peaked roof private dwelling utilizing a stokes basket via the tower ladder. As the
lieutenant in command of this operation, you were correct when you advised the members of the
unit: (5.2.1)
a. The pedestal man should perform the lowering operation in all circumstances
b. Never lash the stokes basket to the top railing of the basket, as this may make a conscious
victim feel insecure and limit the administering of first aid
c. Speed is generally more important than a smooth and careful operation
d. Diagonal placement of the stokes basket is easier and safer
- D
D. The Stokes basket may be placed in an upright or diagonal position and
leaning or lashed to a solid part of basket railing. This position enables
two members to administer first aid if necessary. The Stokes may also be
lashed to the top railings of the basket, however, this is more time
consuming, limits administering of first aid and a conscious victim will
possibly feel insecure since part of his body will be beyond rail of basket.
Stability of rails to be considered.
Note: To insure smooth operation of basket maneuver, the pedestal man should
perform the lowering operation, if conditions permit. (Diagonal placement easier
and safer.)
- Tower ladder streams can be very effective when used to control a large or rapidly moving
fire, but many precautions must be taken to insure a safe operation. Which of the following
statements is incorrect? (6.1)
a. Only the tower ladder officer may order the use of tower ladder streams
b. Large caliber outside streams generally should not be directed into occupied buildings.
However life hazard or fire conditions may demand such use
c. When victims on a fire escape endangered by fire emitting from windows below them, a
fog stream from a tower ladder used at an acute angle to the building can be used to protect them
while the basket moves in for removal
d. The stream does not always have to utilized at its full potential in order to be effective
- A
6.1.1 Only the officer in command of operations may order the use of TL streams.
- Tower Ladder 163 is preparing to operate their large caliber stream to extinguish a fire in a
five story non fireproof factory. The building is involved on several floors and is in the cockloft.
The officer of this company would be correct to instruct her members to: (6.2.2, 6.2.3)
a. Direct the stream into any roof openings, allowing water to enter the cockloft and
extinguish fire below
b. Start heavy stream delivery at the lowest floor and work upwards through the building
c. Extinguish the fire in the cockloft first by placing the nozzle close to and low in the
window
d. Work from the center of the building towards the most serious exposure
- B
6.2.2 When fire building is heavily involved on several floors, heavy stream delivery
should generally start at the lowest level and work upward, effecting a quick
knock-down on the way up to top floor and/or cockloft area, in order to protect
members in basket operating at the highest level. Prevention of fire spread upward
or extension via cockloft is the prime objective. Basket personnel and pedestal
man shall frequently assess conditions on lower floors previously passed.
Operation into lower floors may have to be repeated in order to protect members
in basket to continue operations at highest level.
6.2.3 Positioning the nozzle close to and low in the window will insure:
A. Opening ceiling with stream to expose fire area or cockloft and extinguish
fire therein. Operation into cockloft, work stream from party wall of most
serious exposure toward center of building then from party wall of other
exposure toward center or a roof opening.
B. Maximum stream penetration.
C. Good deflection off ceilings and walls.
D. In extreme situations the stream through attic window of peaked frame
dwelling can be used to ventilate by literally blowing off the roof.
- You are a covering lieutenant in a tower ladder company. The incident commander has just
ordered you to place your tower ladders large caliber stream into operation at a four story
rowframe building. The building is fully involved and you fear that its stability is doubtful. In
this situation, you would be incorrect if you were to follow which guideline? (6.3.2)
a. You insured that the basket was kept beyond the collapse area when possible
b. Only a minimum section of the boom was exposed
c. The basket was kept at a distance of one half of distance horizontally as it was vertically
below the top of the building
d. You ordered the apparatus positioned at the edge of the building, thereby limiting the
exposure of the apparatus in the event of collapse
- C
6.3.2 When used to provide elevated streams, care must be taken to avoid the collapse
of walls on the basket or boom. If fire has been burning for a considerable period
of time and stability of the building is doubtful, the following guidelines are
recommended:
A. Keep basket beyond the collapse area of the building when possible. (See
Section 6.2.3).
B. Expose a minimum section of the boom.
C. Position apparatus so that basket can be placed at the edge of the building
thereby limiting exposure of apparatus in event of collapse. Use two tower
ladders, one at each edge if necessary, to obtain full coverage of building.
D. Directing a stream from above roof area into openings to attack a cockloft
fire is generally counter productive, unless collapse has been extensive
and an exterior attack is in progress. This practice will push fire and heat
back into building and probably cause the hanging ceiling to collapse.
E. Using a large caliber stream onto roof of building with peaked, hip, or
domed roof with a parapet could result in buildup of water at parapet if
run-off is inadequate and thereby possibly cause collapse of parapet. Take
steps to assure such buildup is relieved before moving to operate basket
below parapet if such condition exists.
- Captain Marrotta is preparing to utilize Ladder Company 9’s large caliber stream at a
fourth alarm in the 1st division. Prior to operating, he conferred with the Water Resource Officer
and insured all of the following to insure the optimum effectiveness of the tower ladder stream.
Which piece of information should he disregard? (6.6.1)
a. High pressure engine companies are the best source of supply
b. Supply water to the base of the tower ladder at 200 – 250 psi
c. Generally, only one source of water at the base of the tower ladder is used
d. When necessary to shut down water to the tower ladder, do so at the pumper, not the base
of the tower ladder
- A
A. A Satellite Water Unit is the best source of supply, if available. Largest
diameter hose is used
- A lieutenant supervising a multi unit drill with members of a tower ladder unit was correct
when he informed the probationary firefighter in the tower ladder basket that nozzle pressure
should not exceed how many psi at the tower ladder nozzle? (6.6.2)
a. 250 p.s.i.
b. 100 p.s.i.
c. 75 p.s.i.
d. 450 p.s.i.
- B
- During an extended tower ladder operation during subfreezing weather, members of Ladder
Company 117 lost all control of the basket due to an icing condition. Because the basket operator
was a sharp student, the action he chose that usually results in restoration of control can be found
in which choice? (6.7.6)
a. Notify the officer and chauffeur and have the basket bedded from the pedestal. The tower
ladder is out of service
b. Simultaneously depress and rotate the control handle vigorously while engaging the
“deadman” control
c. Have the chauffeur take control of the basket after shutting down the proper isolation valve
at the base of the turntable
d. Without engaging the “deadman” control simultaneously depress and rotate the control
handle vigorously several times
- D
6.7.6 Loss of control at basket can result if contacts become wet and/or Iced and/or
dirty. Usually only one control movement is affected, e.g., left or right, extend or
retract, etc. Depressing the control handle at basket without engaging “deadman”
and rotating control handle vigorously several times usually results in restoration
of control. If this procedure does not clear condition, operation must be controlled
from pedestal.
- Members of tower ladder 100 were cutting the cornice of a four story rowframe building.
The officer should hold an immediate drill on safe overhauling practices, because the only
correct thing the members of the unit did at this operation can be found in which answer?

a. The top rail of the basket was positioned slightly below the work area
b. The basket was placed against the sagging cornice to secure it against the building
c. A section of the cornice was secured by a utility rope to the basket, lifted from the roof via
the rope, and lowered to the street
d. Small light pieces of cornice were placed in the basket, protruding slightly beyond the
basket railing and lowered to the street
- A
7.1.5 Boom shall not be used:
A. To force timbers or cornices back into building or onto roof.
B. To pull or push objects.
C. As a derrick.
7.1.6 Basket shall not rest against building wall as the movement caused by members in
basket may cause chafing action that could damage basket and/or waterway.
7.2.2 When materials are not too heavy and size is not prohibitive, they may be placed
inside basket and lowered to street, onto floor, up to roof, whichever is most
convenient. Such items should not protrude beyond basket railing.
- After operations are completed and the tower ladder is taking up, the following actions are
taken. Which one is incorrect? (9.1)
a. Drains on the main waterway are opened , supply lines at the 3”x 3” gated Siamese are

9.1.1 Drains on main waterway should be opened while boom elevated at a sixty degree
angle, feedlines at gated siamese removed and gates of siamese opened.
- A tower ladder unit is operating at a fire in a private dwelling when live high voltage
wires servicing the house fall on the apparatus. The lieutenant in command of the tower ladder
should realize all of the following are correct in this situation with which exception?
(8.1)
a. The apparatus should be considered “live” and no member should touch it. Also consider
the supply line and supply pumper.
b. Immediately notify the officer in command and place the tower ladder out of service
c. Attempt to remove the wire utilizing a 10’ wooden hook from an area of safety such as
planking or tires
d. Immediately request a priority response from the utility company
- C
8.1 Live Wires on Apparatus
8.1.1 Live overhead wires can present a problem if they fall on the apparatus. It is
possible for the apparatus to be energized, particularly if the jacks and outriggers
are down in place. If this should occur:
A. No member shall touch the apparatus. Safeguard civilians and other
unsuspecting members. Also consider supply line and supply pumper.
B. Immediately notify the Officer in Command that TL is out of service.
C. Immediately request a priority response of the utility company.
Note: Consideration should also be given regarding operations of TL during
severe lightning storms. Apparatus is grounded and usually wet during stream
operations and in many instances higher than surrounding objects or buildings
- Inspection for safety and maintenance of the tower ladder is of the utmost importance. The
item that does not require daily inspection is found in which choice? (10.1.1, 10.1.2)
a. Basket and pedestal railings
