1. During a recent study group session members were discussing some of terms listed in the glossary section of the various bulletins. The discussion centered around the importance of reading the glossary since examiners can ask questions from the glossary section of the bulletins. Which statement made below is not entirely correct? Glossary

A. A reversed roof is a roof which is raised above the roof beams and supported by 2" x 4"s. The extent to which it is raised varies so as to provide proper drainage on the roof.

B. Fire stopping is the closing of all concealed draft openings to form a barrier against the spread of fire with non-combustible materials.

C. Coaming is a raised frame around a floor, roof opening, or scuttle to keep water from running in.

D. A back stretch is a procedure in which an Engine is placed close to a fire and receives its water supply through a hose line stretched between the engine and a hydrant.

1. D

Back stretch A method of stretching a hoseline. Members pull off sufficient hose at the location of the fire; engine then proceeds to the hydrant. The hose peels off the back of the engine as it travels to the hydrant.

2. After operating at an all hands fire in an old law tenement (OLT) in Manhattan, the Captain of E-99 made the following statements about old law tenements. He was incorrect in which statement below? Section 2.1
A. OLT's are 3 to 7 stories, 20' to 25' wide, 50' to 85' deep, and are class 3 non fire proof construction using brick walls, wood floor beams, and wood floors.
B. The stairway to the cellar is by way of an exterior stair and the first floor (cellar ceiling) is fireproof construction and unpierced.
C. When the building has 4 windows per floor and no front fire escape, it usually indicates 2 railroad flats with a rear fire escape. Railroad flats are those apartments which extend from the front of the building to the rear.
D. When the building has 4 windows per floor and a front fire escape, it usually indicates 3 or 4 apartments per floor with another fire escape in the rear.

2. B

Stairway to the cellar is located inside the building, usually beneath the interior stairway.

3. During a drill about new law tenements (NLT) and non-fire proof multiple dwellings (NFPMD) members were discussing firewalls and fire proof partitions used in the construction of these buildings. These firewalls will have a different termination points depending on when the building was built. Which choice below is incorrect regarding firewalls in NLT and NFPMD construction? Sections 2.2,2.3,2.4.
A. In NLT's built between 1916 and 1929 the fire proof partitions only go as high as the ceiling of the top floor.
B. In a NFPMD built between 1930 and 1940 firewalls were required to be carried to the underside of the roof boards.
C. In a NFPMD built after 1940 firewalls were required to be carried above the roof line.
D. In a NFPMD built on or after 4/18/1929 the size of the area to be enclosed by firewalls is 3000 sq/ft. In NLT's built between 1916 and 1929 the floor areas were required to be broken up into areas of 2500 sq/ft. or less.

3. C
Between 1930 and 1940, firewalls were required to be carried to the underside of the roof boards, and after 1940, to the top of the roof boards. These changes were designed to effectively reduce the size of the cockloft and limit fire spread.

4. Lieutenant Costanza is working a day tour in E-99 and has just arrived, along with L100, at a fire in an old law tenement. The fire is on the 2nd floor in apartment 2F, in the front of the building. There is a heavy smoke condition coming from the 2nd' floor windows and a person is on the fire escape on the 3rd floor directly above the windows where the smoke is coming from. The person is trying to come down the fire escape and is screaming for help. In this situation Lt. Costanza would be correct to give which order below? Section 3.2.2, 4.1.4
A. Order the 1 line stretched to the 2nd floor and extinguish the fire in apartment 2F.
B. Have his members operate the 1st line from the street to protect the person on the fire escape.

4. A

Flame not smoke

3.2.2 In most cases, the first line is stretched via the interior stairs to the location of the fire. The purpose of this line is to protect the primary means of egress for occupants evacuating the building and to confine and extinguish the fire. An exception to stretching the first line up the interior stairs may be made when flame is issuing from windows opening onto the fire escape and endangering people trying to come down the fire escape. In this case, the first line may be operated from the street to protect people on the fire escape. A second line should be promptly stretched to the interior of the building. If the entrance door to the building is self-closing and equipped with a locking device, the first member entering the building should use a chock, rug or other means of preventing the door from locking and thereby delaying other members trying to enter the building.

5

5. As a general rule, outside streams should not be directed into occupied buildings. How ever in some cases, such as heavy fire in a store, an outside stream may be used in an occupied building. Only the incident commander may order the use of outside streams. The incident commander must be a Battalion Chief or above. Section 3.5.10 A C

A. Agree or B. Disagree

5. B

C. Only the Incident Commander may order the use of outside streams. This may be the first arriving officer. For example, the IC may order the deckpipe used for a store fire.

6. At a recent fire on the 3rd floor of a 5 story isolated Old Law Tenement, four hose lines were stretched during the course of operations. Which hose line listed below was incorrectly stretched at this fire? Section 3.2.11
A. The 1st hose line was stretched via the interior stairway to the 3rd floor. When the safety of the stairway was assured the 1®' line was advanced into the apartment to extinguish the fire.
B. The 2nd hose line at this fire was stretched via the interior stairway to back up the 1st line. When the 2nd' hose line was not needed on the 3rd' floor it was stretched to the 4th floor.
C. The 3rd hose line at this fire was stretched via the interior stair to the 5th floor when there was a report that had extended to the 5"' floor.
D. The 4th hose line was stretched to the roof using a rope stretch on the front of the building to extinguish fire in the cornice which could not be reached from below.

6. C

The third line in the building should usually be stretched via the fire escape or rope stretch via a window. This is especially true in Old Law Tenements because the stairway is narrow and the stretching of a third line via the interior stairs would result in congestion and inability to move any of the hoselines.

7

7. Lt. Wright was drilling with his members on the subject of ventilation. Lt Wright told his members that all horizontal ventilation shall be controlled and coordinated by the Ladder Co.Officer operating in the area to be vented. Furthermore, he stated that discretion should be used in the breaking of windows in apartments not involved in fire. Efforts should be made to open these windows when possible. Windows should be opened from the top and from the bottom to allow heat and smoke to vent out and cool air to enter the room. Section 3.3.3
A. 2/3 and 1/3
B. 3/4 and 1/4
C. 1/3 and 2/3
D. 1/4 and 3/4

7. A

3.3.3 All horizontal ventilation shall be coordinated and controlled by the Ladder Company Officer operating inside the area to be vented (fire floor, floor above, etc.). Discretion should be used in the breaking of windows in apartments not involved in fire. Efforts should be made to open these windows where possible and necessary. 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.

8. You are a new Lieutenant working a day tour in E-99, which is a single engine, and is staffed with 5 firefighters. Just after lunch you get a run for a fire in a multiple dwelling. Enroute to the box the dispatcher tells you "it sounds like work" and "we are getting numerous calls". The dispatcher also tells you the Battalion and the 1st due Truck are going to be delayed. Upon arrival you have fire issuing from the store on the 1" floor of a 5 story OLT, and also fire coming from the windows on the 2nd floor directly above the store. There are 2 people on the front fire escape on the 4th floor attempting to come down. You are the only unit on the scene.You would be correct in which choice below? Section 3.4.6,5.5.2

A. You transmit a 2nd alarm on arrival.
B. You transmit a 10-75 and request an extra engine and truck.
C. You transmit a 3rd alarm on arrival.
D. You transmit a 10-75 and request 2 additional trucks.

8. B

3.4.6 The Incident Commander must keep in mind that fire in non-fireproof multiple dwellings can extend very quickly to the floors above and to the exposures. The IC must transmit special calls and/or greater alarms promptly when conditions warrant such actions. For a fire in an Old Law or New Law Tenement, special call an extra engine and truck for fire on two floors. If progress is not made on at least one floor in a short period of time, transmit a 2nd alarm. If fire is in a shaft extending into an exposure, transmit a 2nd alarm. If fire is extending into two exposures, transmit a 3rd alarm.

5.5.2 Additional units: Because of the severe life hazard, height, area and combustible construction of these buildings, an additional engine company and ladder company (beyond a full 1st alarm assignment) should be called for a medium fire condition. That is, when it is anticipated that two lines will be required. When additional units have been special called, they should be given instructions, by radio, regarding positions, masks, extra hooks, etc. If two floors are involved, or at extensive cockloft fires, it will generally be necessary to transmit a 2nd alarm. The time that it takes 2nd alarm units to arrive must be considered under these conditions.

9. During afternoon drill one day Lt. Smith made the following four points. He was only correct in which point? Section 3.5.9
A. Gas meters are always found in the cellar and will never be found in the apartment itself or in a public hallway.
B. Piping containing flammable gas is allowed to be run in a stair enclosure or a shaft containing a standpipe riser.
C. If gas meters are burning the fire should be extinguished immediately and then the gas supply should be shut down.
D. If gas is leaking without being ignited, the gas supply should be off and the area vented as much as possible.

9. D

If gas is leaking without being ignited, the gas supply should be shut off and the area ventilated as much as possible. Members should be moved away from the area of the leaking gas. Fog lines may be used for venting. A leak or break in the piping may be stopped or greatly diminished by stuffing rags, paper, etc., into the break.

10

10. When operating at cellar fires in Old Law Tenements members should know which point below is not in accordance with FDNY procedures? Section 4.2

A. The 1"' hose line stretched at a cellar fire in an OLT should be stretched to the cellar entrance door which is located inside the building under the interior stairway on the 1st floor.
B. The 1st hose line should remain at the cellar entrance door on the 1st floor to protect people coming down the stairs and to extinguish fire which may be extending up from the cellar via partitions, voids, and dumbwaiter shafts.
C. The 1st hose line should not advance down the cellar stairs if there is an outside entrance to the cellar at the front and rear of the building unless the fire is small to medium in size.
D. The 2nd hose line stretched should be advanced into the cellar by way of the front or rear entrance to the cellar.

10. C

4.2.1 The first line should be stretched to the cellar entrance door which is located inside the building, under the interior stairway on the first floor. This line should remain at this position to provide protection for people coming down the stairway and to extinguish fire which may be extending upwards from the cellar via partitions, dumbwaiter shafts and other voids. This line should not be advanced down the cellar stairs if there is an outside entrance to the cellar at the front or rear of the building, unless the fire is minor.

11

11. When operating at a store fire in an Old Law Tenement a 2 1/2" line must be stretched for medium or large fires since the store may involve a large amount of combustible material. A 2nd hose line should be immediately stretched to the floor above to extinguish any fire that may extend to the floor above. Section 4.3.1

A. Agree
B. Disagree

11. B

4.3.1 Store fires in OLTs may involve a large amount of combustible material. A 2 ½" line should be stretched for large volume fires and a second line stretched to the entrance hallway. When assured that the second line is not needed on the first floor, it may be advanced to the floor above the fire.

12

12. Portable ladders may be placed over weakened, damaged, or burnt out stairs in order to
safely gain access to the upper floors of a building. Which ladder listed below is the preferred
ladder to place over a burnt, damaged, or weakened stairway? Section 4.S.5

A. Straight Ladder
B. Extension Ladder
C .Scissor Ladder
D. "A" Frame Ladder

12. B

4.5.5 Portable ladders may be placed over weakened, damaged or burnt-out stairs in order to safely gain access to upper stories of a building. The preferred ladder for
this is the extension ladder, rather than a straight ladder. The shorter nested length allows easier maneuverability and positioning, while the adjustable length
should insure proper coverage of the entire stair span. The butts shall be supported by the floor at the base of the stair, while both upper beams at the tip of the ladder should rest on the upper floor landing for proper support.

13

13. Lt. Strawberry is working a night tour in E-99 and has just arrived with his unit at a fire in an OLT. The fire is in apartment 2L on the second floor. The fire is blowing out the windows of a bedroom and into the shaft on the exposure 2 side of the building. There is a heavy fire condition in the shaft and the fire has also spread to the living room and kitchen in the apartment. Lt Strawberry would be correct to take which action listed below? Section 4.7

A. Order the 1st hose line stretched to the roof of the building and have the nozzle man operate
the line into the shaft to extinguish the fire in the shaft.

B. Order the 1st hose line stretched into the cellar since the fire in the shaft can bum down into the cellar.

C. Order the 1st' hose line stretched to apartment 2F and extinguish the fire in the bedroom, living room, and kitchen and then direct the hose line to be operated into the shaft to extinguish the shaft fire.

D. Order the P' hose line stretched to apartment 2F and extinguish the fire in the bedroom. After the bedroom fire is extinguished have the line operated into the shaft to extinguish the fire in the shaft. Then extinguish the living room and kitchen.

13. D

4.7.6 For fires in rooms in the vicinity of a shaft, after the fire in the room has been knocked down, the line should be operated into the shaft in order to knock down the shaft fire before continuing through the apartment for knockdown and final extinguishment

14

14. During BISP members of L-lOO were discussing Old Law Tenements. Which point made by the members of L-100 is correct? Section 4.8.1 A, 4.8.8,4.8.5 B
A. Because of the short span of floor beams (25'), and the fact that the floors are heavily loaded, the collapse of floors in OLT's is usually a problem.
B. Rear tenements may be found behind OLT's. These rear tenements are usually 25' to 50' behind the front building. Usually it is necessary to go through the front building to get to the rear building.
C. Rear tenements are small in area and may be of frame or non- fireproof construction and may range from 2 to 5 stories in height.
D. In some areas 2 or 3 adjacent OLT's have been altered and interconnected to create one building with one street entrance. All the original avenues for fire spread common to OLT's have been eliminated in these renovated buildings.

14. B

C. The distance between the front building and the rear building varies, but is somewhere between 10 to 25 feet usually.

15

15. On some OLT's party wall balconies will be found. In the event of a fire, the occupants would use the fire escape balcony to escape to an adjoining building. Which point below is incorrect regarding party wall balconies on OLT's? Section 4.8.7
A. The fire escape can be used to gain access to the roof since a gooseneck ladder will found on the top balcony.
B. Firefighters cannot use the fire escape to go from one floor to another for ventilation and search purposes.
C. The fire escape cannot be used for stretching hose lines.
D. Party wall balconies connect two or more buildings.

15. A

The fire escape cannot be used to gain access to the roof.

16

16. Which type of stairway listed below is considered to be a tremendous asset in heavy fire operations on the top floor of a New Law Tenement? Section 5.2.5
A. Transverse stairs
B. Wing stairs
C. Isolated stairs
D. Scissor stairs

16. A

Transverse stairs-these stairs are usually located at points remote from each other, but a person can go (transverse) from one stairway to another via the public hall on all floors of the building. Their layouts ease evacuation, assist in examination and permit lines to be stretched to any apartment, via any stairs. They are a tremendous asset in heavy fire operations on the top floor.

17

17. The number and location of stairways do not adhere to a common pattern in New Law Tenements. Some stairways will be found near the front entrance while others will be some distance away. Which point below regarding stairways in New Law Tenements is incorrect?
Section 5.2.5
A. It is essential that once the stair layout is recognized in a NLT, this information must be relayed by handle talkie as this is vital in the size up picture.
B. Transverse stairs are usually located at a point remote from each other, but a person can go (transverse) from one stairway to another via the public hall in the lobby of the building only.
C. Wing stairs, one or two, are located at the front and rear of each wing. The floor landing leads to a public hall that will join the other stairs in that wing only (if two stairs). The public hall does not transverse to the other wing of the "H".
D. Isolated stairs are usually identified by their individual entrances. Access is limited to the apartments served by the stairs and there is no access to other wings so hoseline operations are confined to their limited area.

17. B

17. The number and location of stairways do not adhere to a common pattern in New Law
Tenements. Some stairways will be found near the front entrance while others will be some
distance away. Which point below regarding stairways in New Law Tenements is incorrect?
Section 5.2.5
A. It is essential that once the stair layout is recognized in a NLT, this information must be
relayed by handle talkie as this is vital in the size up picture.
B. Transverse stairs are usually located at a point remote from each other, but a person can go
(transverse) from one stairway to another via the public hall in the lobby of the building only.
C. Wing stairs, one or two, are located at the front and rear of each wing. The floor landing
leads to a public hall that will join the other stairs in that wing only (if two stairs). The public
hall does not transverse to the other wing of the "H".
D. Isolated stairs are usually identified by their individual entrances. Access is limited to the
apartments served by the stairs and there is no access to other wings so hoseline operations are
confined to their limited area.

18

18. You are working a day tour in L-33 when you arrive at a fire in a 6 story new law tenement. The fire is on the 5th floor and is blowing out the windows in the throat, court yard, and the front of the building. The IC orders you to set up the tower ladder and to attack the fire using the tower ladder stream. You would be correct to take which action below?
Section 5.4.2
A. Order the stream operated into the front windows first and then knock down the remaining fire in any order.
B. Order the stream operated into the front windows, then the windows in the court yard, and finally into the windows in the throat.
C. Order the stream operated into the windows in the throat first, then the windows in the court yard, and finally into the windows in the front of the building.
D. Order the stream operated into the windows in the court yard first, then the windows in the front of the
building, and finally the windows in the throat of the building.

18. C

5.4.2 Aerial ladders, if first to arrive, should not be positioned so as to block off the front entrance courtyard. When possible, this position should be taken by a tower ladder. If rescue operations must be performed, the aerial shall, of course, be positioned to carry out this function. If the fire is showing out windows in the throat, courtyard
and front windows, and a tower ladder stream is being used, it should be directed at the windows in the throat first. The stream should then be advanced toward the
front of the building and finally operated into the front windows.

19

19. When operating at fires in the newer large "H" shaped buildings with steel frame construction the probability of fire extension is greatly increased due to the many shafts, voids, and recesses that may be found. Which choice listed below is the most probable point for
vertical fire extension? Section 5.2.6, 5.10.1
A. Dumbwaiter shafts
B. Vertical steel channels
C. Closets, since their usually constructed above one another
D. Pipe recesses

19. B

5.10.1 Checking for fire extension: When a heavy fire is encountered in one apartment,
all sides and above and below the fire area, must be examined. Nothing can be
taken for granted. The most probable point for vertical fire extension will be the
vertical steel channels (in buildings that have steel frame construction). These
columns have no specific location and many are completely hidden. Any boxed
out area is there for a purpose and, if involved in fire, must be opened up and
examined. Closets are another very probable point of vertical extension. At
times the vertical steel columns are located in the walls of these closets. Fires in
channel rails necessitate opening up above and at the top floor ceiling to check for
extension into the cockloft.

20

20. Construction of "H" type buildings has remained basically the same for over 100 years. The exterior walls are masonry, and generally of brick. The floors, roof, and interior framing are partly or wholly of wood and columns and girders are unprotected steel. Which point below
regarding top floor and roof construction in these "H" type buildings is correct? 5.2.4
A. The cockloft is a large concealed void between the top floor ceiling and the underside of the roof boards. It is large enough to be considered an attic and will have at least one point of entry.
B. The cockloft is required to be subdivided in some cases by fire stopping. This fire stopping will always restrict the spread of fire.
C. The most common roof has the top floor ceiling several feet below the main roof beams.
The roof boards are fastened directly to the top of the roof beams.
D. The most common roof is an inverted, raised, or reversed roof. The main roof beams are at
ceiling level and a frame work is raised above these beams with the roof boards attached.

20. C

B. The most common roof has the top floor ceiling several feet below the main roof beams. The roof boards are fastened directly to the top of the roof beams. This provides for a sturdy roof. In the inverted, raised or reversed roof, 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. (Figure 11)
If 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.

21

21. E-99, E98, E-97, LI00, and LI01 are 10-84 and operating at a fire on the top floor of a 4 story NFP multiple dwelling. The fire started in and is now burning in the cockloft. Battalion 1 is stuck in traffic and Division 2 was involved in an accident on the way to the box. The 1st line
has been stretched by E99 and E98 and is in operation. The officer of E97 orders his unit to put their cockloft nozzle into operation and tells the control firefighter to go to the Engine and get the cockloft nozzle. He told his members that the hose for the 2nd line will be used to operate the cockloft nozzle. Do you agree or disagree with the order from the Officer of E97?
TB Tools 7, Data Sheet 18
A. Agree or B. Disagree

21. B

2.2 The cockloft nozzle is carried by all Squad Companies and Division vehicles.

22

22. While Division 2 was visiting the quarters of E99 and LI00, members removed the cockloft nozzle from the Division vehicle and had an impromptu drill. Which point made about the cockloft nozzle was incorrect? TB Tools 7 Data Sheet 18
A. The cockloft nozzle is designed to extinguish fires in the confined space of any building with a cockloft. The cockloft nozzle cannot be used at any other type of incident.
B. A hole, approximately 3' x 3' is needed in the ceiling in order for the cockloft nozzle to fit. A minimum of 4" is needed between the top of the ceiling joists and the bottom of the roof Joists.
C. When using the cockloft nozzle in a NFP Multiple Dwelling, the preferred location for operation is immediacy inside the apartment door as this will give members with a degree of protection provided by the public hallway.
D. Do not rotate the cockloft nozzle in a continuous counter clockwise direction as this action may cause the nozzle to become unscrewed from the shut off. The use of the cockloft nozzle does not eliminate the need of pulling ceiling for final extinguishment and wash down.

22. A

2.1 The cockloft nozzle is designed to extinguish fires in the confined space of any building with a cockloft. The cockloft nozzle should NEVER be the primary attack line and is ONLY to be used when supported and protected by an additional conventional handline.
Note: The IC shall consider use of the cockloft nozzle at any incident where its unique
capabilities may be beneficial.

23

23. While operating as the FAST truck at an all hands for a fire in a NFP Multiple Dwelling, you decide to explain to the proby how the FDNY identifies the various wings in these large buildings. The building you are operating at has 3 wings, each of which is connected by a throat.
You would be correct to tell the proby? Section 5.6
A. The 1st officer inside the building will let the IC know how the particular building designates its various sections. We will then be guided by the particular buildings designations.
B. Standing in front of and facing the fire building and beginning on your extreme left, wings
shall be designated A, B, C, D etc. The entire wing from front to back of the building shall be A, B. etc.
C. Standing in front of and facing the fire building and beginning on your extreme left, wings shall be designated 1, 2,3,4 etc. The entire wing from front to back of the building shall be 1,2, etc.
D. Standing in front of and facing the fire building and beginning on your extreme right, wings shall be designated 1, 2, 3, 4 etc. The entire wing from front to back of the building shall be 1,2, etc.

23. B

5.6.3 Standing in front of and facing the fire building and beginning on your extreme left, wings shall be designated A, B, C, D etc. The entire wing from the front to
the back of the building shall be A, B, etc. The wing shall be further subdivided by the term: front and rear or front, center and rear, if necessary. That part of the building connecting each wing shall be designated the throat and shall be referred to as the throat between A wing and B wing etc. (Figure 15) At an escalating fire it may be necessary to establish subordinate levels of command in the wings of the building. The same description of building wings can be used to describe the assignment i.e., Sector A, B, C, D or if necessary Branch A, B, C, D.

24

24. Listed below are different dimensions of openings required or suggested at different operations. Which one listed below is the only correct one? (Taxpayers 5.5.16,Ladders 3 5.9.6, MD's 5.9.9, PD's 6.3 and 11.3, Ladders 6 TL Ops. 4.3)
A. At a fire in a taxpayer cutting a 6' x 6' hole is recommended in providing ventilation at the roof.
B. A coffin cut is approximately 4' x 6'.
C. When cutting a trench in the roof of an MD, the trench should be at least 4' wide and about 20' from the initial vent hole.
D. To access a fire in the attic of a private dwelling from the floor below, a 3' section of ceiling should be opened up

24. D

5.5.16 Cutting a hole eight feet by eight feet is recommended in providing ventilation at the roof. In a serious fire, instability, heat, or smoke conditions may make the cutting of this primary vent hole impossible, delaying overall effective ventilation.

5.9.6 Sequence - The size and location of the opening will depend on fire conditions. A suggested method to make an expandable opening "COFFIN CUT" is as follows: A. Assume wind is blowing in direction indicated. (Ideally at your back) B. Cut #1 approximately 3 feet. C. Cut #2 "knock out" corner cut for tool insertion. D. Cut #3 approximately 6 feet. E. Cut #4 to #7 approximately 3 feet. F. Leave removed pieces of roof section next to opening to warn operating forces. G. If larger opening is needed, additional opening can be made in like manner. (Continuation of cut in desired direction) H. Make sure that roof is not opened before cut is completed. I. Push down ceiling to complete ventilation.

C. To be effective, the trench must be properly located, at least 3' wide, and cut from wall to wall or other suitable fire stop, such as a stair or elevator bulkhead. Failure to complete a trench may allow a fire to pass to the other side of the trench.


25

25. Lt. Carter is operating at a fire in the cockloft of a 1 story taxpayer. Lt. Carter has been assigned as the roof sector supervisor and decides to have members operating on the roof start a trench cut. Lt. Carter immediately notifies the IC that a trench cut has been started. Do you agree or disagree with Lt. Carter's actions? Taxpayers 5.6.4
A. Agree or B. Disagree

25. A

5.6.4 The Roof Sector Supervisor can start a trench cut where he/she sees the necessity for it. Immediate notification to the Incident Commander of the operation is mandatory.

26. One of the techniques used to stop the spread of fire in a cock loft is to cut one or more trenches in the roof. Which point made during drill about trench operations is incorrect? 5.9.9
A. Trenching is an offensive operation performed to limit the extension of fire in the cock loft. A trench should be cut and pulled immediately after there is a vent opening directly over the fire.
B. To be effective a trench must be properly located, at least 3' wide and cut from wall to wall or other suitable fire stop such as a stair or elevator bulkhead.
C. A charged line should be in position on the roof to protect personnel and the trench opening. This line may be operated into the trench in a brief, sweeping, side to side motion to prevent fire from extending across the opening.
D. Personnel cutting a trench or a ventilation hole on a roof must be assured a way of getting off the roof. Keep all personnel off the roof on the fire side of the trench.

26. A

B. Trenching a roof is a defensive operation that is performed to limit the extension of fire in the cockloft. A trench may be cut, but should not be opened, until there is an adequate vent opening directly over the fire. Ideally, the trench should be precut, but not pulled. Two or more inspection holes may be cut on the fire side of the trench. When, and if, the fire reaches the inspection holes, the precut trench is pulled. This sequence lessens the possibility of the fire moving rapidly and prematurely towards what is, in effect, a second distant opening (the trench) cut in the roof.

27. FF Smith made the following three statements:

1 Know the floor, wing, section, side or exposure where you are operating. It is essential that all members at the scene use the same terminology. A fire escape in the throat often spans the firewall and indicates two (2) separate apartments in the throat.

2 One apartment in the throat may span a firewall with no fire escape and have two interior exits, one to the stairway in one wing and the other to the adjacent wing. Both doors are usually openable and not obstructed by furniture. A search of this apartment must be thorough.

3 The law requires the subdivision of these large NFP Multiple Dwellings into smaller areas. However, there is no way to determine the location of these subdividing walls from the outside of the building, except in these few cases where they are continued above the roof. Which statements are correct?
A. 2 and 3
B. 1 and 2
C. I and 3
D. All are correct

28. Units are operating at a fire in a 14 story hi-rise fireproof multiple dwelling (HRFPMD). The fire is on the 7th floor in apartment 7A. Which unit listed below is responsible to ensure the elevators are recalled and searched at this fire. 6.4.1
A. The 1st arriving ladder co.
B. The 2nd arriving ladder co.
C. The FAST truck.
D. The 4th arriving ladder co.

28. B

6.4.2 Stairs shall be used when the fire is on the seventh floor or below. The first arriving ladder company shall recall the elevators, whether or not they will be used. The second to arrive ladder company shall ensure that all elevators are recalled and searched. Regardless of the fire floor, the IC must ensure that all elevators are recalled, searched and controlled early in the operation, preventing civilians from placing themselves in danger by entering the elevator cars during the incident.

29. E-99 and L-100 have just arrived at a report of a fire on the 14"' floor of a 26 story HRFPMD. Upon arrival in the lobby the officer of E-99 sees that there are 2 elevators, however one of them is out of service. The remaining in service elevator is equipped with fireman service and only serves the odd floors. Outside operations are not possible since the building is located in the middle of a cluster of other buildings. Which action listed below would be correct for members of E-99 and L-100 to take at this operation? Section 6.4
A. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, and the Nozzle firefighter should use the elevator and take the elevator to the 11"' floor.
B. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, Nozzle, and Control Firefighter should use the elevator and take the elevator to the 11"* floor.
C. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, Nozzle, and Control Firefighter should use the elevator and take the elevator to the 12"' floor.
D. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, and Control firefighter should use the elevator and take the elevator to the 13"* floor.

29. A

6.4.5 Overloading of elevators must be avoided or the units responding will be delayed arriving at the fire/emergency floor. A stalled elevator car is an elevator car out of service. Look for maximum load signs and consider each member and their equipment to be greater than 275 pounds.

6.4.6 When both the engine and ladder companies arrive together and only one elevator is available (non fireman service), the ladder officer with the forcible entry team and the engine officer with two firefighters (nozzle & control) with all rolled up lengths and standpipe kit shall go up first. If the elevator has Firemen Service, and no outside operations are indicated, the OV will be operating the elevator. This will necessitate reducing the elevator load by one of the engine firefighters. Remaining members in the lobby are to make up a second team for the next elevator or consider using the stairs. This approach will allow these members to begin setting up equipment for the appropriate attack strategy and size-up information to be conveyed to the IC and all other operating units.

30. Which choice below correctly shows where elevators should be located after all units are in position when operating at a fire on the 23'" floor of a 45 story HRFDMD and two elevators area available and serviceable? 6.4.8
A. One elevator in the lobby and one elevator at the location of the Fire Sector Supervisor.
B. Both elevators at the location of the Fire Sector Supervisor.
C. Both elevators in the lobby.
D. One elevator in the lobby and one elevator 1 floor below the location of the fire sector supervisor.

30. D

6.4.8 After all units are in position, and two elevators are available and serviceable, maintain one elevator on standby in the lobby and one two floors below the fire. This would allow the transport of members required for relief and/or transport of injured members or civilians down to the lobby.
