1. Although the term “Taxpayer” is not recognized in the building code, there are three broad categories of taxpayers. Which one is described correctly? (Sec. 2.2, 2.3.1, 2.3.2, 2.3.3)(A) The older type of taxpayers, built from the turn of the century until the 1920’s, are all of Class 3 construction and have masonry exteriors.(B) In the older type of taxpayer, a decorative metal cornice will be found in the front, and the supports will be weakened and fall if there is any fire in the cockloft.(C) Metal cornices found in the front of taxpayers constructed from the turn of the century until the 1920’s can be removed to provide access to the cockloft area.(D) The most prevalent type of taxpayer, built from the 1920’s into the 1960’s, may have cornices of the façade type or signs in the front of the building. Removing the cornice or sign will usually provide access to the cockloft area.(E) The newer type of taxpayer, built since the 1960’s, rely on increased combustible construction, mainly wooden I-beams used to support the roof.

1. C2.3.1 The older type built from the turn of the century until the 1920's. This type is usually one story in height but there are some that have two stories. Some of theolder structures have partitions, girders, beams, and columns of wood and may be considered wood frame buildings although most have masonry exteriors.When there is a heavy fire in the front of the building, the supports of these cornices can be weakened and the cornice can fall to the ground unexpectedly.2.3.2 The most prevalent type built from the 1920's into the 1960's. Cornices, of the facade type, and signs are often attached to the front of the building outside off the brick walls. Removing the cornice or sign in most cases will not provide access to the cockloft area.2.3.3 The newer type construction built since the 1960's. These contain the same type of occupancies and the structural features will be similar to the previous types except that the use of combustible construction material has been reduced. In many of these buildings the difference will be the steel bar joists that are used to support the floors and roof in place of wood beams.

2. While responding at 0300 hours as the 1st Battalion Chief to a 10-75 for a fire in a taxpayer, you remark to your aide that you hope there are sprinklers present. You would not expect to find sprinkler protection if the fire building was found in which choice? (Sec. 2.5.1, Mercantile Guide p. 12-16)(A) Built in 1943 and the building is 75’x100’(B) Built in 1975 and the building is 80’x100’(C) Built in 2011 and the one story building dimensions are 125’x125’(D) Built in 2012 and the three story building dimensions are 125’x200’(E) Built in 2013 and the one story building dimensions are 80’x100 with the stock stored in high-piled racks.

2. ARules 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 24,000square feet. (BC 903.2.6)Storage of merchandise is in high-piled racksor rack storage arrays (BC 903.2.6.1)OCCUPANCY WITHIN BUILDING-Areaexceeding 7,500 square feet OR area of anysize is located 3 stories above grade OR areaof any size is located in a High Rise buildingOR area of any size contains an unenclosedstair or escalator connecting two or morefloors. (BC 903.2.6.2)

3. There are various types of roofs and roof support systems found in taxpayers. It is very important for the Incident Commander (IC) to obtain this information at a taxpayer fire. Which choice correctly describes these features? (Sec. 3.3.1, 3.3.3)(A) The most common type of roof on taxpayers is plywood supported by open web joist or steel bar joist. These joists are supported at approximately 20 foot intervals.(B) Updated calculations have revealed that the wooden bowstring truss may only support 60% of the load they were originally designed to hold.(C) Snow that drifts due to the wind can be significantly deeper in one area, especially behind raised parapet walls on bowstring truss roofs. This eccentric (off-center), unbalanced, concentrated load, can create an overload on the trusses.(D) In the older type of wooden bowstring trusses, the trusses may be spaced up to 60 feet apart.(E) Open web steel joists, found in modern taxpayer construction, have fire resistance ratings of 5 to 10 minutes.

3. C3.3.1 There are many types of roofs on taxpayers but the most common is constructed of wood joists covered with either tongue and groove boards or plywood. Theroof is then covered with combustible waterproofing material commonly called "tarpaper" or "built up roofing" which may be several layers thick. Sometimes a layer of tin is found under the tarpaper in old taxpayers. The roof joists may be supported at approximately 20-foot intervals, by exterior brick bearing walls, interior load bearing studded partitions, wood or steel girders supported by steel lally columns or wood columns. The roof may have skylights and scuttle openings, signs, air conditioners and heating units. (See Fig. 6)Updated calculations have revealed that bowstring truss roofs may only support 40% of the load they were originally designed to hold.I. In older type truss roof buildings, the trusses may be spaced 10 or 20 feet apart with roof beams installed between the trusses to support the roofcoverings.A. Open web steel joists, found in modern taxpayer construction, have no fire resistance rating. Fire rating depends upon the ceiling finish and finishNote: See section 5.5.26 for operational procedures in structures with open web steel joist roof support systems.roofing.

4. While attending the BC Command Course, a newly promoted BC is listening to a presentation on construction features found in taxpayers. Which statement should be corrected? (Glossary, Sec. 3.5.1, 3.6.1, 3.6.2, 3.6.4, 3.7.1)(A) Canopies and marquees that are cantilevered over the sidewalk can act as a lever on the parapet wall pulling down a long section of it. Although a marquee is not supported by posts or columns, it is required to have drainage facilities.(B) Steel “I” beams are often built into side or rear masonry walls, of butt the front parapet wall, where they are supported by masonry piers or iron columns. An average 50 foot steel beam heated uniformly over its length to 970 degrees Fahrenheit will extend in length approximately 4 inches.(C) When steel “I” beams are heated from 1000 to 1500 degrees Fahrenheit, their yield strength drops dramatically and they start to soften and fail. After 5 to 10 minutes at a fire, these beams can be heated beyond their strength limitation.(D) Cooling a steel member will cause it to regain its strength and load carrying ability. If a steel beam has already sagged under the weight of the floors or roof, cooling the steel will contract it to its original length.(E) Cast iron columns fail on the average in about 30 minutes in fire endurance tests.

4. C3.6.3 When these steel beams are heated from 1000 F to 1500 F, their yield strength drops dramatically and they start to soften and fail. This temperature can bereached in five to ten minutes at a fire and it is only a matter of time at an uncontrolled fire (thirty minutes for the smaller beam sections), until these beams can be heated beyond their strength limitations.

5. Collapse is one of the major concerns of the IC at a fire in a taxpayer. The IC would consider all of the following with the exception of which choice as warning signs of impending collapse? (Sec. 3.9.4, 3.13.2, 4.2.5)(A) Collapse of the first floor due to the extensive cellars commonly found in the new type of taxpayers.(B) A heavy body of fire which has been burning out of control for 20 minutes or more, particularly in a large open floor area.(C) Sagging or bulging walls. One cubic foot of brickwork weighs about 100 pounds.(D) Inability to make successful headway against a heavy fire condition within 20 minutes into the operation at the fire.

5. AAnswer A. Many of the newer type of taxpayers are built on a concrete slab foundation, which removes a major problem of cellar and basement fires.

6. At 0400 hours, you respond to a reported fire in a 1 story taxpayer divided into five separate occupancies. You arrive on scene and see heavy black smoke pushing from underneath a roll down gate in a pizzeria, which is in the middle of the row of stores. There is no Engine Company on scene, and the first arriving Ladder Company is beginning to cut the roll down gates as the Roof FF is ascending a portable ladder placed to the roof. Which of the following would be an incorrect tactic to take? (Sec. 4.4.1, 4.5.2, 5.1.5, 5.4.2, 5.5.26)(A) You ordered the 1st Ladder Company to wait until the Roof FF cut the roof over the pizzeria before opening the door to the pizzeria.(B) You informed the 1st Ladder Company that performing vertical ventilation before an Engine Company is on scene will not increase the intensity of the fire, unless horizontal ventilation is also performed.(C) After the Roof FF informed you via HT that there was a skylight on the gypsum plank roof, you ordered the Roof FF to evacuate the roof immediately before breaking the skylight. You then ordered the 1st arriving Engine Company that was arriving at the Command Post to discharge their hoseline into the pizzeria as soon as forcible entry was performed.(D) You informed the 1st Ladder Company that if 25% of the pizzeria occupancy contains the mixture conducive to backdrafts, the entire pizzeria may explode if oxygen is introduced into the environment.

6. BNote: It must be understood that ventilation will increase the intensity of the fire if it is not carefully coordinated with engine hoseline operations.

7. While supervising roof cutting operations, the Roof Sector Supervisor notifies you that the roof is an inverted roof, and requests additional companies. You would be incorrect in considering which point? (Sec. 5.3.3)(A) Although the inverted roof may be pitched from the front to the rear, front and rear to the center, or from the front rear and sides to the center, in most cases the high portion of the cockloft is at the front of the building.(B) If the fire enters the cockloft at the high point or front of the building, the fire problem is less severe than if it has entered into the cockloft at the rear.(C) Since most fires originate in the front of the cellar where stock is often stored near conveyor chutes, this is the area from which the fire usually extends to the cockloft.(D) The standard (flat) roof may have little or no pitch. If it is pitched, it will be from the front to the rear.

7. CC. Since most fires originate in the rear of the first floor where utilities, storage, and services are located, this is the area from which the fire usually extends to the cockloft. Generally, this is the lowest portion of thecockloft. The pitch of the roof (front to rear) allows the fire to spread rapidly to the higher cockloft area.

Answer Questions 8 - 10 based on the following:At 0100 hours, you are working in Battalion 30 and respond as the first BC to a fire in a taxpayer type building with 8 occupancies. Upon arrival, the Roof FF from Ladder 100 informs you via HT that the roof appears to be a plywood roof supported by wood joists, and there is heavy fire in the cockloft. You transmit a 2nd alarm, and begin your size-up.8. Due to the severity of the fire in the cockloft, you recognize the importance of roof operations and consider several points. Which one should be corrected? (Sec. 5.4.12, 5.4.13, 5.4.14, 5.5.20)(A) You assign the Rescue Company Officer as the Roof Sector Supervisor as soon as you arrive on scene.(B) The immediate ventilation and cutting of an effective size hole on the roof calls for two saws and four members on the roof. The Roof Sector Supervisor must be a Battalion Chief when more than one power saw is working on the roof.(C) The 1st Arriving Engine Officer, a newly promoted Lt., was correct to call for two additional Ladder Companies immediately upon arrival.(D) After determining that roof cutting is critical, you order the 1st Battalion Chief assigned on the 2nd alarm to report to the roof to become the Roof Sector Supervisor.

8. B5.4.12 The immediate ventilation and cutting of an effective size hole on the roof calls for two saws and four members on the roof. Additional staffing with properequipment should be assigned to this position as soon as possible. A Roof Sector Supervisor must supervise roof operations when more than one power saw is working on the roof.5.4.14 A Roof Sector Supervisor should be assigned as early as possible to supervise roof operations. This could be a chief or company officer as designated by the IC.

Answer Questions 8 - 10 based on the following:At 0100 hours, you are working in Battalion 30 and respond as the first BC to a fire in a taxpayer type building with 8 occupancies. Upon arrival, the Roof FF from Ladder 100 informs you via HT that the roof appears to be a plywood roof supported by wood joists, and there is heavy fire in the cockloft. You transmit a 2nd alarm, and begin your size-up.9. While considering the responsibilities of the Roof Sector Supervisor you have several thoughts. Which one is incorrect? (Sec. 5.4.9, 5.6.4(A) At times, as the roof cut is made and pulled, members may be driven back by the heat or fire and be unable to complete the opening. If this occurs, additional openings must be started and completed. The Roof Sector Supervisor may choose the new locations based on their size-up without approval of the IC.(B) If the Roof Sector Supervisor determines that a trench cut is needed, they must make immediate notification to the IC and receive approval before the trench cut is started.(C) At times, as the roof cut is made and pulled, members may be driven back by the heat or fire and be unable to complete the opening. If this occurs, additional openings must be started and completed. The Roof Sector Supervisor may choose the new locations based on orders from the IC.(D) The Roof Sector Supervisor can start a trench cut where he/she sees the necessity for it. Immediate notification to the IC is mandatory.

9. B5.6.4 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.

10. After the fire is successfully extinguished, you discuss tactics with the Fire Sector Supervisor. After stressing that nothing affects the outcome of an operation as much as ventilation at a taxpayer fire, you make several other statements. Which one is incorrect? (Sec. 5.5.1, 5.5.14, 5.5.15,(A) The key to ventilation is the cutting and pulling procedures used to provide the necessary escape for the fire, heat, smoke and gases. Trenching is also an important factor, but in most cases not to the degree of the ventilation cuts.(B) It cannot be assumed, once an initial determination is made on the run of joists, that all joists throughout the same building run the same. In most cases joists will run in the same direction, but there are exceptions.(C) When rear extensions were added to taxpayers, it was not unusual to utilize a larger girder to tie the older sections in with the newer section. This at times makes the rear portion of the added roof higher than the older portion(D) At cellar fires, it is often necessary to cut the first floor to provide the necessary means of ventilation. The cut should be made as near to the windows and doorways as possible, and sometimes made in the aisles if it is under a skylight.(E) At times due to intense heat, smoke, or a lack of horizontal ventilation, the roof must be opened over the ventilation holes on the first floor. This tactic can be used if members are operating on the first floor or cellar.

10. DThe cut should be made as near to the windows as possible and away from doorways and aisles. When the run of the floor joists has been established, the cut should be extended at right angles to the joists. Thisprovides additional cellar ventilation, maximum ventilation of the bays between joists and access points for streams

11. With increased knowledge regarding bowstring truss roof construction, a cautious approach must be adapted, regardless of the fire area. The IC may implement an interior attack after a risk assessment has been performed based on which one of the following factors? (Sec. 5.5.25)(A) Structural stability of the building determined at the last BI inspection.(B) Any known or suspected life hazard.(C) Size and location of the fire.(D) Potential of safe access to fire area.

11. C Current structural stability of the building. Any known life hazard. Size and location of the fire. Verification of safe access to fire area.Acronym: CAVS

12

12. In which of the following choices are proper guidelines being followed? (Sec. 5.5.25)(A) Members are prohibited from operating on the roof of a content fire in a building with a metal bowstring truss.(B) Interior operations are prohibited at a fire in a vacant buildings with bowstring truss roof construction.(C) At a large fire where the timber truss is involved, interior operations are not permitted(D) At an advanced fire where the underside of the roof is involved, interior operations are prohibited.

12. ANote: 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.B. At vacant buildings with bowstring truss roof construction, exterior operations should be the primary tactical consideration.C. At large and/or advanced fires, or where the timber trusses or the underside of the roof are involved in fire, exterior operations should be the primary tactical consideration.

13

13. In which scenario did a Battalion Chief not show full understanding of FDNY tactics? (Sec. 5.5.25)(A) Members were instructed to use a thermal imaging camera to check the ceiling from below upon entering a building with a bowstring truss in an attic area above the ceiling.(B) Members operating an a tower ladder bucket were instructed to make a triangular cut in the sloping hip section in the front of the roof to determine if fire entered the truss area in a building with a bowstring truss located in an attic area above the ceiling.(C) When members operating from a tower ladder bucket determined that a small fire was involving the truss space above a ceiling, interior operations were immediately discontinued in accordance with FDNY procedures.(D) Members were ordered to operate a hoseline from the roof of an uninvolved occupied building with a bowstring truss roof into an adjoining factory building that was involved in fire.

Answer C. When members operating in a tower ladder bucket make a triangular cut in the sloping hip sections of the FRONT or REAR of the roof and fire is found to involve the truss space, a collapse zone must be adhered to and exterior operations should be the PRIMARY tactical consideration.

14. Units are operating at a fire at 123 Town Line Road. The CIDS for the building is as follows:COMMERCIAL – 1 STY 125’x 75’ – CL3LWLIGHTWEIGHT OPEN WEB STEEL ROOF JOIST-GYPSUM PLANK ROOF – TAXPAYER TYPE WITH8 OCCUPANCIESUpon arrival, you see an aerial ladder to the roof and receive several HT transmissions. In which one is a proper understanding of FDNY tactics displayed? (Sec. 5.5.26)(A) The Rescue Officer transmits “While cutting the roof we had a white powder emanating from the cut. Cutting operations have stopped and members are quickly venting the skylights and evacuating the roof.”(B) The Roof FF from Ladder 300 transmits “I am not cutting the roof due to the bar joists. I am breaking a window located near the roof line to provide horizontal ventilation and evacuating the roof.”(C) The Officer of Engine 200, the 1st arriving Engine Company transmits “We are making progress on knocking down the fire from the interior using the reach of the stream”.(D) The Officer of Engine 200, the 1st arriving Engine Company transmits “We are conducting operations from the exterior as required due to the presence of the gypsum plank roof covering”.

14. CH. Gypsum concrete decking is of lightweight construction, spans wide spaces and is vulnerable to moisture. These characteristics are conduciveto early collapse under fire conditions. Therefore, members shall not be committed to roof operations. Interior operations shall be conducted fromareas of safety due to the weight of such decking materials (17.5 lbs. per sq. ft.). The presence of a gypsum roof deck will be indicated by a white powdery residue during saw operations. Upon this observation, membersshould immediately notify the Roof Sector Supervisor and IC and evacuate the roof.

15

15. All of the following situations would require the transmission of a 2nd alarm at a Taxpayer fire with the exception of which one? (Sec. 5.7.4)(A) When two handlines are operating on an advanced fire in a store.(B) Extension to the cockloft(C) Extension to an adjoining occupancy.(D) An advanced fire in the cellar.

15. A5.7.4 When two handlines are operating on an advanced fire in a store, special call an extra engine and ladder. Transmit a second alarm for extension to the cockloft, adjoining occupancy or for an advanced fire in the cellar. The need for additional ladder companies at these operations is great, anticipate such and special call asneeded.

Answer Questions 16 - 20 based on the diagram below and the following information:You arrive at 1000 hours on a Wednesday to a medium fire condition in the cellar of the 99 Cent Store, which is one of four occupancies in a 150’x75’ one story Class 3 Taxpayer. The Taxpayer is fully sprinklered, and there is a Siamese on the front of the building. There is an “H type” multiple dwelling adjoining the Taxpayer, separated by a fire wall. The cockloft of the Taxpayer is undivided. Your original assignment on this Box has 3 Engine Companies and 2 Ladder Companies, one of which is a Tower Ladder and one rear mount aerial ladder. When the 10-75 was transmitted, the FAST Truck assigned was a rear mount ladder company.

 

16. Upon arrival, you notice that there is one portable ladder placed to the roof on the exposure 1 side, exposure 2 side and exposure 3 side of the Taxpayer building, and the Tower Ladder is in front of the 99 Cent Store. The Aerial Ladder is set up in front of the Pizza occupancy. Which thought is incorrect? (Sec. 5.7.5, 5.7.6, 5.7.7, 5.7.8, 5.7.14, 8.1.19, 8.2.2)(A) You need at least one additional portable ladder placed in front of the Taxpayer building.(B) Any additional Tower Ladders shall be placed on an adjoining street due to the first two Ladder Companies attainment of proper positioning.(C) If the fire extends to the 1st floor, you should call for an additional Chief Officer to supervise operations on that level.(D) You should establish the Command Post near the front of the building but outside the collapse zone.

16. B8.1.19 Tower ladders should be positioned in front of the building in preference toconventional aerials. Heavy stream appliance is now in position if needed for thefire building or to protect exposures.

When the 10-75 was transmitted, the FAST Truck assigned was a rear mount ladder company.17. You hear a HT transmission stating that an interior cellar stair has been located, along with an exterior stair to the cellar in the front of the 99 Cent Store. You quickly size-up the Engine Company operations and determine if their tactics are correct. Which one action taken was incorrect? (Sec. 7.1.2, 7.2.2, 7.2.3, 8.1.20)(A) The initial hoselines stretched should be 2 ½”.(B) The first hoseline was stretched through the exterior stair to the cellar of the 99 Cent Store due to it being the quickest route to the fire.(C) The 1st and 2nd Engine Companies may supply the sprinkler system, but the 3rd Engine Company must ensure that the sprinkler system is supplied.(D) As a last resort, the first floor may be flooded with the Stang nozzle or the tower ladder pipe. The tower ladder basket can be positioned a foot or two above the street level.

17. BD. When there is an interior stair to the cellar, especially if it is an open stair, and conditions permit, the first line must be stretched to this point to prevent the spread of fire and to permit operations on the first floor.

Manual Ch. 10 Add 2 Sec. 8)(A) 2B(B) 2(C) 2-OA(D) O-2B

20. C8. Illustration #5 depicts a fire that originated in the "H" building and has extended to theleft into the taxpayer. It has advanced down the row of stores to the third store andthreatens the fourth store. The "H" type building is identified as "O", the taxpayer isexposure "2" and the first store or subdivision of the taxpayer is identified as "2-0". The"2" indicates the first building on the left; the "O" following a number indicates that weare now referring to a subdivision. The second store is "2-OA", the third store is "2-OB",the fourth is "2-OC", the fifth is "2-OD", the sixth is "2-OE". The next building is aseparate building, not part of the taxpayer and is identified as exposure "2A", then "2B",etc. The buildings opposite the fire building represent exposure "1" because either theseparation is thirty feet or less or the intense fire creates an exposure problem.

21. Which choice is correct concerning cockloft fires in a Taxpayer? (Sec. 3.2.1, 7.1.8, 7.3.3, 7.3.5)(A) The cockloft usually extends over all of the stores in the building and is 2-3 feet high.(B) Hoselines may not be operated directly into roof openings.(C) The IC shall order a handline with a cockloft nozzle into the interior to knockdown the fire in the cockloft.(D) A hoseline may not be operated into a trench cut.(E) The first Engine Company must always stretch the 1st hoseline into the store under the main body of fire.

21. C3.2.1 The cockloft is the space above the finished ceiling and the underside of the roof sheathing. It usually is a common area extending over all the stores in the structure and can vary in height from four inches to more than six feet.7.1.8 In many cases where entry is delayed or where the pulling of ceilings is impossible due to fire conditions or ceiling construction, a hoseline or lines operated properly into a trench cut may confine the fire.
