5.
You are a operating with your unit at an alarm for an odor of gas from a manhole. Due to a fourth alarm in your borough, you are the only unit on the scene. There is a strong odor of natural gas emanating from a sewer manhole in the intersection near your apparatus. You order the round cover of the manhole removed by two members of your unit utilizing manhole hooks. Your actions at this incident were: (2.9, TB Emergencies 2 pg. 15)
a.
Incorrect mainly because removal of a sewer manhole cover can only be performed with the approval of an on scene Chief officer
b.
Correct, if removing the manhole cover will possibly alleviate a potentially explosive situation
c.
Incorrect. Only square manhole covers may be removed by fire department members
d.

7.
Four firefighters desiring to become lieutenants were discussing FDNY procedures for fires/emergencies in transformer vaults. These students would be correct to believe: (3, 3.1, 3.2, 3.3)
a.
The greatest hazard encountered at fires/emergencies in transformer vaults is the amount of toxic PCB’s contained within.
b.
Full use of personal protective equipment and SCBA is mandatory, even in a light smoke condition
c.
The New York City Fire Department considers only those transformers with greater than 49 ppm (parts per million) to be PCB transformers
d.
Sub surface transformers convert primary voltage (27,000 volts) to secondary voltage (120 volts). Although both are dangerous only the primary voltage can cause fatal injury.

7. B
The transformers convert primary voltage (27,000 Volts) to secondary voltage
(120 Volts) for use by CON EDISON customers. Either of these voltages can
cause fatal injury if not handled properly.

8.
An engine and ladder company arrive together at a below grade transformer emergency in Greenwich Village. There is a heavy smoke condition from an open transformer vault in the street and witnesses are informing you, the Ladder Company Captain that there may be a civilian in the transformer vault itself. In this situation you would be incorrect to believe? (Ref. #1 2.3, 2.4, 2.5 AUC 266 6.4.2)
a.
No member is to enter the vault until Con Edison has made an examination
b.
The Incident Commander will make the determination that the vault is safe for entry by FD personnel
c.
When authorization is given to enter the vault a cursory search of the vault shall be performed

a.
Its vulnerability to moisture
b.
Its truss support system
c.
It is an unstable platform prone to early collapse
d.
Its heavy weight (gypsum plank approx. 135 lbs but may vary, gypsum concrete approx. 17.5 lbs. per sq.ft.)

1. A

15

2.
You are a lieutenant in an engine company. Your unit is performing afternoon BISP in a taxpayer building. The building has a roof which is comprised of gypsum concrete supported by unprotected lightweight open web steel joists. In regard to this building, it would be incorrect to state which of the following?
a.
This roof shall not be cut
b.
Members should not be committed to roof operations
c.
An exterior attack is to be utilized
d.
A watertight roofing material is applied to the gypsum concrete after it sets

2. C

16

3.
You are the roof firefighter cutting a roof at a one story commercial building. As you make the initial cut, you notice a white powdery residue being thrown from the saw blade. In this situation you would be correct if you were to: (3.2.4)
a.
Make an immediate notification to your company officer and proceed to evacuate the roof

17

1.
From the following taxpayer related definitions, choose the one that is not correct. (Glossary)
a.
A parapet is that portion of a wall which continues above the roof line.
b.
A marquee is a permanent hood which projects over an entrance to a building and is supported by neither posts nor columns
c.
Corbelling is a course of brick built out from the face of a wall, as steps in reverse
d.
Cantilevered structural members are vertical and supported on two ends

1. D

18

2.
The term taxpayer is not defined or recognized in the building code. It is commonly taken to mean a business structure of one or two stories in height of Class 3 construction. In regard to taxpayer type buildings, it would be incorrect to state: (2.1, 2.2)
a.
The term originally referred to the practice of real estate investors, who while holding land for speculation, resorted to minimal investment in construction to produce income and offset the cost of taxes
b.
Their areas may vary from 20’ x 50’ to areas of whole city blocks
c.
Taxpayer type buildings were usually constructed with cheap flimsy construction and little or no fire retarding features
d.
These buildings are usually multi structures built side by side with substantial fire resistive partitions and fire stopping in the cockloft

2. D

19

3.
There are three broad categories of taxpayers. From the three, choose the statement that contains incorrect information. (2.3, 3.13)
a.
The older type of taxpayer was built from the turn of the century until the 1920’s. Features of this type of taxpayer may include tin ceilings nailed directly to the beams or furring strips, decorative metal cornices through which fire can spread, and wooden beams girders and columns.
b.
The most prevalent type, built from the 1920’s into the 1960’s. Usually larger than the old style taxpayers, they may contain supermarkets, bowling alleys and restaurants. In most cases, removing the cornice or sign will not provide access to the cockloft.
c.
The newer type of taxpayers built since the 1960’s contain the same type of occupancies with similar structural features. The difference in these buildings is the use of larger wooden structural members to support the floor and roof.
d.
The newer type of construction is much better than the traditional or older type from a fire protection standpoint.

3. C

3.13 NEW TYPE CONSTRUCTION
3.13.1 The new type of construction (supermarkets, etc.) is much better than the
traditional or older type from a fire protection view point.
3.13.2 Many of the newer type taxpayers are built on a concrete slab foundation, which
removes a major problem of cellar and basement fires. The partition walls are
usually better constructed due to the use of the steel and aluminum stud system
which employs gypsum blocks and sheathing as a bearing or nonbearing wall
system.
3.13.3 The roof system will remain a major fire fighting factor because, for the most
part, the roofs are constructed of "Bar Joists," light weight steel or flat wood
trusses. These features, and how they behave under fire conditions, have been
covered under "Truss Roofs," Section 3.3.3. (See Figs. 5 & 10).

20

4.
The officer of Ladder Company 173 is operating at a restaurant fire in a taxpayer. CIDS information has informed the officer that the occupancy that his unit is operating in has a mezzanine. Concerning the mezzanine, the officer should consider all of the following with which exception? (2.4)
a.
Access to the mezzanine is generally via a small wooden stair or ladder. Very seldom will there be another means of access.
b.
The height of the ceilings in the mezzanine and the area below is generally above average
c.
The majority of mezzanines will not be enclosed and there will be a railing at the edge
d.
Mezzanines can be found in all areas of the building (front, rear, sides). Many were added after the original construction date and may be constructed of lighter load bearing components

4. B

21

5.
While on BISP, a firefighter under your command has asked you whether the taxpayer building your unit is inspecting is required to have sprinkler protection. The building card you are holding states that the building was erected under the 1968 building code. You told the firefighter that the sprinkler protection is required if the building exceeds how many square feet? (2.5.1)
a.
7,500
b.
6,500
c.
5,000
d.
1,000

5. A

Rules for sprinkler protection:
1938 Code Area exceeding 10,000 square feet.
1968 Code Area exceeding 7,500 square feet.
2008 Code-Group M-Mercantile FULL BUILDING-Area exceeding 12,000
square feet OR the combined area on all
floors including mezzanines exceeds 24,000
square feet. (BC 903.2.6)
Storage of merchandise is in high-piled racks
or rack storage arrays (BC 903.2.6.1)
OCCUPANCY WITHIN BUILDING-Area
exceeding 7,500 square feet OR area of any
size is located 3 stories above grade OR area
of any size is located in a High Rise building
OR area of any size contains an unenclosed
stair or escalator connecting two or more
floors. (BC 903.2.6.2

22

6.
Firefighters in a study group from the borough of Brooklyn were studying the construction features of taxpayer buildings. They would be correct to believe that the most common type of roof on taxpayers can be found in which choice? (3.3.1)
a.
The inverted, raised or reversed roof
b.
Wood joists covered with either tongue and groove boards or plywood
c.
Bowstring truss
d.
Unprotected open web steel joists roof

6. B

23

7.
Many taxpayers built both past and present utilize truss construction to support the roof. Trusses are used where large areas free of roof support columns are desired. A Captain ordered by the Incident Commander to supervise roof operations at a taxpayer fire would know which piece of information to be incorrect? (3.3.3)
a.
All trusses are comprised of two major members called chords (top and bottom) and webs. The webs tie the top chord to the bottom chord.
b.
Because of the redundancy built into the truss by the webs, the failure of smaller truss elements will not cause a complete failure of the entire truss.
c.
The wooden bow string truss is easily recognizable by its characteristic hump like profile. The longer the span, the higher the bow.
d.
Steel open web joists found in modern construction have no fire resistance rating and may collapse after only 5 or 10 minutes.

7. B

24

8.
Exterior bearing walls in taxpayers are constructed of brick, stone, concrete block and mortar. Differential thermal expansion may cause these walls to bulge. Other correct statements concerning taxpayer walls can be found in all but which choice? (3.4)
a.
Brick walls usually crumble or break as they fall, but large sections can be projected a good distance due to the impact as the wall hits the ground
b.
The parapet walls are required to be supported laterally if they extend for long distances above two or more stores. They also receive support at the ends where they tie into crosswalls
c.
The stability of masonry walls is very much dependent on the integrity of the roof, which acts as a monolithic brace which ties the walls together. In effect the roof is holding up the walls by supplying lateral support
d.
Stone or brick walls may spall due to heat or subsequent stream application, thereby reducing the effective load bearing area of the wall

8. B

25

9.
Officers in the FDNY must be aware of the characteristics of steel “I” beams and how they will affect firefighting operations. An officer would be incorrect if she were to believe which choice in regard to steel “I” beams? (3.6)
a.
An average 50 foot long steel beam heated uniformly over its length to 970 degrees will extend approximately 4 inches. A longer “I” beam will expand a proportionately greater distance and as the temperature increases, the rate of expansion increases.
b.
At 1000 – 1500 degrees F the yield strength of steel drops dramatically and it may soften or fail. This can occur in five to ten minutes at an uncontrolled fire.
c.
Cooling steel “I” beams or columns with hose streams will cause them to crack or fail.
d.
A large heavy “I” beam will be able to absorb more heat and its temperature rise more slowly than a thin lightweight beam.

9. C

26

10.
Two firefighters from a Bronx engine company were advancing a hoseline into the basement at taxpayer fire. As they were making the push towards the main body of fire, the lieutenant heard them make the following statements. He ordered the line shut down and corrected them in which one? (3.6.4, 3.7)
a.
Cast iron columns are unpredictable and have been known to fail in 30 minutes during fire endurance tests.
b.
The failure of a column is generally more serious than the failure of a girder or beam.
c.
The failure of a column in the cellar will usually not cause a subsequent collapse of the floors and roof
d.
When cooling structural steel members firefighters should not be allowed in the collapse zone. Cooled beams will contract to their original size and this shortening may pull the ends of such beams off their supports or twist the beams causing them to drop.

10. C

27

11.
Firefighters from Engine Company 16 and Ladder Company 7 are operating at a taxpayer fire. The fire has been located in the suspended ceiling of a nail salon. In regard to suspended ceilings in taxpayers, it would be incorrect to state: (3.8)
a.
When initially pulling suspended ceilings, members should be in a safe area in case of total failure.
b.
As many as two or three ceilings may be found in a particular store.
c.
Suspended ceilings should be punched with a hook for water detection, fire conditions, and to check construction
d.
Suspended ceilings constructed of wire lathe, plaster or tin often fail and fall section by section, rather than all at once

11. D

28

12.
Fighting a fire in the cellar of a taxpayer can be a long an arduous operation. While responding to an alarm for a fire reported in the cellar of a taxpayer, an officer would be incorrect to believe which choice? (3.9, 3.10)
a.
In the older type taxpayers, the flooring under the first floor may not be extended under the raised front window display area. Paneling can be removed for ventilation and water application.
b.
In the newer type taxpayer slab construction and concrete floors are prevalent with no basements or cellars in the building
c.
Do not expect the layout of the cellar to conform to the layout of the stores above
d.
Terrazzo floors are a tremendous asset to units operating above the fire as the terrazzo flooring will confine the fire to the cellar.

12. D

3.9.2 Heavy terrazzo or concrete is sometimes placed over wood joist floor
construction, an exceptionally hazardous condition. A fire in the cellar may
weaken floor supports with little evidence of heat conditions on the first floor.
These floors are difficult to ventilate to allow early advance of cellar lines or use
of cellar pipes and distributors. Sudden failure due to weight on the floor is
possible.

29

13.
Ladder Company 109 and Engine Company 241 arrive first due to a taxpayer fire. Heavy smoke is pushing protected by metal roll down security doors. Incorrect statements concerning these types of security doors can be found in which choice? (3.11)
a.
The weight that is added to the front walls, especially when the doors are in the open position can cause the lintel over the store front to fail and the wall and door assembly to fail during the fire.
b.
It is common to find numerous case hardened padlocks securing these doors. They must be cut with a power saw or torch.
c.
The bottom of these doors may rest on the sidewalk entrance doors to the cellar causing a delay in operations.
d.
The motor hoist will usually prevent the door from coming down hard once it starts down, after a loss of spring tension

13. D

30

14.
Structural collapse is always a major concern during any fire, but particularly during a fire in a taxpayer. From the following indicate the one choice which is not a cause of collapse at a taxpayer fire. (4.2.1 D)
a.
Backdrafts blowing out walls or floor
b.
Weakened and burned out structural members
c.
Walls leaking smoke or water
d.
Accumulation of a large volume of water on a floor or in a ceiling

14. C

31

15.
A backdraft, smoke explosion, or a hot air explosion is the ignition and rapid combustion of a mixture of flammable gas or dust and air which flashes back through the openings around the fire area. In a typical backdraft, the one element which is missing just prior to ignition is: (4.4.1 F)
a.
High heat condition
b.
Combustible gasses
c.
Air or oxygen
d.
Highly heated contents

15. C

32

16.
You are an Acting Battalion Chief working a 6x9 tour in Staten Island. It is 4 a.m. and you have just arrived with units from your battalion at a taxpayer fire with smoke pushing under pressure from the roll down gates. It is your belief that there is a definite possibility of a backdraft occurring at this fire. The most effective order for you to issue at this fire can be found in which answer? (4.4.1 K, L)
a.
Immediately begin forcible entry on the roll down gates in order not to delay the initial attack on the fire.
b.
Order the roll down gates cut with a carbide tipped blade. After the gates are removed, order the windows vented utilizing 12 foot hooks from a side or flanking position. Attack the fire from flanking positions until it has darkened down.
c.
Withhold the initial street level attack until the roof firefighter notifies you that there is a sufficient hole cut in the roof and it has been pushed down.
d.
Order forcible entry to begin immediately, and simultaneously have the roof firefighter cut a sufficient hole in the roof.

16. C

33

17.
As fire develops in a taxpayer, the heat smoke and gasses generated will spread horizontally and vertically throughout the entire structure. In regard to fire travel in taxpayers, the only accurate statement can be found in which choice? (5.3.3)
a.
In most cases the high portion of the cockloft is in the rear of the building
b.
If fire enters the cockloft in the rear of the building, the fire problem is usually less severe than if it had entered the cockloft in front
c.
Most taxpayer fires originate in the rear of the first floor where service areas, storage and utilities are generally found
d.
The standard or flat rood usually has little or no pitch. The configuration of the building and the position of the drainage facilities will usually determine its pitch

17. C

34

18.
Under which condition MUST a roof sector supervisor be assigned by the Incident Commander at a taxpayer fire? (5.4.12, 5.5.20)
a.
More than one power saw operating on the roof
b.
One saw and four members on the roof
c.
Anytime a hole is being cut on a taxpayer roof
d.
Four or more members on the roof

18. A

35

19.
You are the first due BC to arrive at a fire in a taxpayer. The fire is in the cockloft, you have just transmitted the all hands, and it appears that cutting the roof will be critical to the management of this fire. Which member or members should you assign as the roof sector supervisor? (Choose all that apply. 5.4.14)
a.
Special Called Chief Officer
b.
4th due engine officer
c.
All hands chief
d.
2nd due truck officer

19. A

36

20.
A fire in a taxpayer generally involves cutting a hole in the roof. The Captain of a Brooklyn ladder company would be incorrect if he were to issue which order to his roof fighter at a taxpayer fire? (5.5.6, 5.5.9, 5.5.16, 5.5.27)
a.
Order the hole on the roof to be 8’ x 8’ in size
b.
Insure that the smaller 4’ x 4’ segment of the roof cut pulled prior to completing the entire cut. This will insure ventilation and avoid a backdraft in the cockloft or occupancy below.
c.
Have the roof firefighter cut on the windward side of the cut to insure the quickest and most effective cutting
d.
Roof cuts should be made in one operation and lifted in one piece. All obstructions below the cut should be removed or opened by pushing down from the roof through these openings

20. B

37

21.
You are a ladder company Captain arriving who has just reported in to the command post at a third alarm fire in the cellar of a taxpayer. The IC has ordered your unit to cut a ventilation hole in the first floor of the fire occupancy. Your well trained unit knows all of the following to be correct when cutting taxpayer floors? (5.5.22, 5.5.23)
a.
The floor should always be cut directly over the main body of fire
b.
For safety purposes floor cuts should be made away from storefront windows
c.
All floor cuts must be covered by hose lines
d.
Floor cuts should be made near the main aisle

21. C

38

22.
You are a Battalion Chief supervising operations at a fire in an occupied automobile dealership with a bowstring truss roof. You have received a report from the first ladder company to arrive that the fire is on the first floor of this one story structure and has not extended into the truss. Choose the correct answer in regard to roof ventilation at taxpayer fires with bowstring truss roofs. (5.5.25)
a.
Roofs of bowstring truss construction should not be ventilated from the roof
b.
Members should never be committed to the roof ventilation at this type of construction
c.
All interior forces should be withdrawn immediately and an exterior operation should be started
d.
In determining whether or not to commit members to roof ventilation, the IC must consider the location of the fire, extent duration and intensity.

22. D

Note: Under no circumstances shall any member operate on the roof
of any building involved in a content or structural fire with a
wooden, metal or combination bowstring truss design

39

23.
Ladder Company 20 arrives second for a fire in a taxpayer. CIDS Information has indicated that the roof of this building is supported by lightweight open web steel joists. The officer of this company should realize which is true in regard to this type of roof system? (5.5.26)
a.
Roofs with this type of roof system are not to be cut
b.
Members may not operate on this roof
c.
Vertical ventilation of this type of roof system is not to be attempted.
d.
The most common roof decking used with this type of support is the gypsum concrete roof deck.

23. A

40

24.
You are a covering lieutenant working a day tour in the Bronx. The Incident Commander has ordered you to supervise roof operations at a taxpayer cellar fire. The fire is doubtful and you fear it may extend into the cockloft. You order personnel operating on the roof to begin a trench cut. Your actions were: (5.6)
a.
Incorrect. Only a Chief officer may order a trench to be cut
b.
Correct, as long as the trench is at least two feet wide
c.
Correct, if you immediately notify the Incident Commander
d.
Incorrect, trenching is not to be used at a taxpayer fire

24. C

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.

41

company's line which may be used for any of the following:
1. To control the first floor if the first engine company has advanced
into the cellar via the interior cellar entrance.
2. Serve as a backup or protection line for the first engine company.

31. A

B. Cockloft Fires
First engine company: - When fire has control of the cockloft and the
need for exposure protection is critical, position the engine to utilize the
deckpipe. In-line pumping will give good positioning and allow room for
placement of a tower ladder.

occupancy/building, depending on life hazard and the location and
severity of the fire.
2. Refer to Section 7.1.2 and 7.1.4 for hose sizes and operating
procedures.
3. When exposures are not an immediate problem, then the first line
should be stretched into the store under the main body of fire and
operated to extinguish the fire.
