F.O. CLASS #8 - Week of 11/11/18: AUC 207, T.B. – Fires 7 & 8, ERP – Add #4A - D, Eng Ops #5 - 7 Instructor: BC Mike Barvels Flashcards
1) Subway operations are usually complex in nature and all officers should be familiar with established Department procedures. Of the following choices, which contains correct information regarding subway operations? (AUC 207 2.1 - 2.5)
A) Fire Department personnel will never be permitted to operate on track areas unless assured that the power is off; no exceptions.
B) Whenever evacuation or removal of passengers from a train at other than a station is contemplated, the power shall be ordered off.
C) Positive assurance of power shut-off will be verified through the Fire Department dispatcher or any Transit officer or employee equipped with a Transit radio, before power is assumed to be off.
D) Operations shall be conducted with the maximum commitment of manpower deemed necessary and with a maximum of supervision.
- B
- 1 Fire Department personnel will never be permitted to operate on track areas unless assured that the power is off. This rule may be ignored only if life is in imminent peril and direct and immediate action is required to save life. In the latter instance, every possible precaution should be taken to minimize the risk.
Positive assurance of power shut-off will be verified through the Fire Department dispatcher before power is assumed to be off.
2.5 Operations shall be conducted with the minimum commitment of manpower deemed necessary and with a maximum of supervision.
2) Two newly promoted Lieutenants were discussing subway operations and power removal. Which comment made was incorrect? (AUC 207 3.2, 3.2.1, 3.2.5, 3.2.6)
A) The first consideration on arrival at an operation involving electrified track will be a determination of whether the power is to remain on or turned off.
B) When power removal is required it shall be accomplished at all times via apparatus radio through our own Dispatcher.
C) Whenever power is removed, interior subway car lights will turn off, indicating that power has been removed.
D) Subway cars can receive power from the third rail via a contact rail shoe(s). When members are required to operate under a subway car, request that Transit personnel protect the contact rail shoes of the affected cars with wooden slippers.
- C
- 2.5 Whenever power is removed, lights in the right of way, the station lights, signals, drainage pumping equipment, tunnel ventilation equipment, and train headlights will not be affected. Interior subway car lights, found to be either on or off, shall be no indication that power has been removed. The only verification that power has been removed shall be via the FDNY Dispatcher, as per Section 2.3 of this bulletin.
3) Lt. Green made one incorrect comment when conducting a subway drill in quarters. Indicate the incorrect comment. (AUC 207 3.2.4, 3.3.1)
A) When there is immediate danger and power must be shut off to save lives in imminent danger, the nearest power removal box shall be used and the Desk Superintendent shall immediately be notified, via the emergency telephone, that power is to remain off.
B) Failure to notify the Desk Superintendent of power removal at the power removal box will result in immediate restoration of power.
C) A power removal box and emergency telephone will be located near a blue light.
D) If power is reported off by Transit personnel upon our arrival, the Fire Department Dispatcher will not need to be notified to confirm power removal.
- D
- 3 If power is reported off on our arrival:
- 3.1 The Fire Department Dispatcher must still be notified to confirm power removal.
4) Subway fires can range from simple, rubbish fires to complex operations requiring evacuation. All of the following choices contain correct information regarding subway fires except in which choice? (AUC 207 3.4-3.8)
A) When conditions do not require power removal, reconnaissance may be conducted by an Officer and a firefighter operating as a team and only from platforms or catwalks. Tracks shall not be entered or crossed.
B) If the direction of smoke travel can be established, a unit shall be sent to the next emergency exit or station in an attempt to isolate the source of the fire. Information will be relayed to the Officer in Command via Handie-Talkie or apparatus radio.
C) Engine Companies shall not connect to a hydrant until the fire is located. Determination of the most direct means to the fire will be made before a line is stretched.
D) Emergency exits might prove the most direct means of access to a fire area and the establishment of the initial hoseline will always be given priority use of this means over evacuation.
- D
3.7 Emergency exits might prove the most direct means of access to a fire area. However, evacuating passengers will always be given priority use of this means. When ordered to use an emergency exit, the officer should check his TA emergency exit booklet and make
sure that he is on the correct line and track before members are committed to the track area. All units that have emergency exits in their district or first response area should have all members aware of their location.
5) In underground areas, handie-talkie communication with the surface will be adversely affected. A relay system shall be set up to overcome this. All choices below contain correct information regarding subway communications except? (AUC 207 4.1)
A) Handie-talkie communications are poor from level to level. Communications in a straight line are from fair to poor.
B) An engine and truck can set up a relay with 2 to 6 members. Members who are part of the communications relay must maintain their position throughout the operation until relieved by the Incident Commander.
C) If the token clerk booth is within 50 yards of stairs to street, the LCC should contact the train dispatcher through the clerk. There is a telephone in the token clerk’s booth.
D) In the Handie-Talkie relay, the Engine Officer should be located approximately 50 feet from the stairs on the platform for relay.
- D
Truck Chauffeur Bottom of subway entrance stairs. If the token clerk booth is within 50 yards of stairs to street, contact train dispatcher through the clerk. (There is a telephone in the token clerk’s booth. Try to obtain additional information for the Company Officer and Incident Commander). The LCC should relay the token booth phone number to the Truck Officer in
case it is necessary to call the booth from a blue light telephone.
Outside Vent FF The foot of the stairs leading to the platform if it is within 50 yards of the Chauffeur.
Roof FF Approximately 50 yards from the stairs on the platform for relay.
Engine Officer Approximately 100 yards (line of sight) from Roof FF on the platform.
Truck Officer To location of the fire.
Additional HT equipped members every 100 yards, if necessary.
6) Due to the complex nature of subway operations, members may find themselves operating in ways different than what they are used to. Which tactic below is incorrect? (AUC 207 4.1-5.1)
A) Conditions may be such that all members are not needed in the relay to transmit messages to grade level. In this case, only members needed to establish an effective relay shall be used, beginning with the Truck Chauffeur.
B) A proper transmission in a subway for the first arriving Truck, Ladder 4, conducting a communications relay would be “Ladder 4 to Ladder 4 Roof.”
C) If a train is available, consider use of the radio in the train to accomplish a message relay from the train to the desk superintendent to the borough communications office.
D) Engine Chauffeurs should not hook up until the location of the fire is determined. All Engine Company personnel should be committed to getting the first line into operation.
- B
Note: Members in the relay are reminded to use proper intra-unit communications. The Officer of the unit will be identified by the unit number (Ladder 4). Other members in the relay will be identified by unit number and riding assignment and the term “RELAY”
(Ladder 4 OVM Relay). EXAMPLE: Company Officer: “Ladder 4 to Ladder 4 Roof Relay. Notify Command there is a rubbish fire 100’ south of the southbound platform.”
Ladder 4 Roof: “Ladder 4 Roof Relay to Ladder 4 OVM Relay. Notify Command there is a . . . the southbound platform.”
Ladder 4 OVM: “Ladder 4 OVM Relay to Ladder 4 Chauffeur Relay. Notify Command there is a . . . the southbound platform.”
Ladder 4 LCC: “Ladder 4 Chauffeur Relay to Command. Ladder 4 reports there is a rubbish fire 100’ south of the southbound platform.”
7) Two members of your unit were discussing firefighter tactics in the subway. Which comment made was incorrect? (AUC 207 5.1, 5.2, 5.4.1, 5.4.2)
A) The Can FF should carry a wooden hook instead of a Halligan hook. For hoselines, an FT-2 nozzle should be used.
B) When walking out on the benchwall to extinguish a fire in the track area of a tunnel, the Officer, Irons FF and the Can FF are required. Other members of the company should act as safety people and be stationed on the platform where the benchwall is located, and also on the opposite platform.
C) The only justification for being on the track area with live (energized) 3rd rail power and moving trains, is if civilians are on the tracks, and we must keep them away from the third rail to save their lives or if going to the blue light to remove power because of life hazard.
D) If fire is on an express track, and the extinguisher cannot reach the fire, then power will have to be removed.
- B
5.4.2 When walking out on the benchwall to extinguish a fire in the track area of a tunnel, the Officer and the Can FF should be sufficient to achieve our purposes.
Other members of the company should act as safety people and be stationed on the platform where the benchwall is located, and also on the opposite platform.
Notification of oncoming trains should be made by radio and verbal communications by these members.
8) Most fires in a station are of a minor nature (e.g. rubbish fire in a trash receptacle, papers on railroad ties, or an overheated ballast at station lights.) An extinguisher will usually control these fires. There are occasions, however, when the fire will be under the platform. If this is the case, members will not be permitted in the track area unless certain conditions are met. Which condition is listed incorrectly? (AUC 207 5.3, 8.6)
A) Power is removed and confirmation of power removal is received from the Fire Department Dispatcher.
B) Members are posted at each end of the platform to act as safety people.
C) An alternate area of refuge is assured in case of train movement.
D) Areas of refuge are identified by diagonal red and white stripes painted on a wall.
- D
8.6 NO CLEARANCE SIGNS
Along the walls of tunnels we will find “no clearance” signs. They are identified by diagonal red and white stripes painted on a wall. It may appear that there is clearance at this location but train overhang on turns and contact shoes will hit you if you are standing there.
9) During serious incidents in the subway, evacuation may be required. In this case, you would be correct to follow which procedure listed below? (AUC 207 5.6)
A) Upon reaching the train, make contact with the train operator or conductor and see if the intercom system works. If it does, have a Fire Department member make an announcement that the Fire Department is on the scene and that the situation will shortly be under control.
B) If the intercom system does not work on the train, several members walking either on benchwalls or alongside the train can go as far as the last car, notifying people of our presence. This is critical to controlling panic and subsequent self-evacuation.
C) One of the best ways to reduce panic is to provide increased lighting. There should be a high degree of light along the right of way, in addition adequate lighting at the train debarkation point and close to the exit.
D) If at all possible, people should be evacuated to a station through the train. In situations where the train is unable to proceed to a station, consider transferring passengers to another train, after consulting with transit officials. Never walk passengers out of the tunnel using the roadbed or benchwall.
- B
5.6 EVACUATION
Upon reaching the train, make contact with the train operator or conductor and see if the intercom system works. If it does, have that person make an announcement that the Fire Department is on the scene and that the situation will shortly be under control. If the intercom system does not work, several members walking either on benchwalls or
alongside the train can go as far as the last car, notifying people of our presence. This is
critical to controlling panic and subsequent self-evacuation. One of the best ways to reduce panic is to provide increased lighting. There should be adequate light along the right of way, in addition to a high degree of lighting at the train debarkation point and
close to the exit.
There is a possibility that thousands of people will have to be evacuated. If at all possible people should be evacuated to a station through the train. In those situations where the train is unable to proceed to a station, consider transferring passengers to another train, after consulting with transit officials. As a last resort, walk passengers out of the tunnel using either the roadbed or benchwall.
10) Fires located on elevated roadways and railways present their own significant challenges. Of the following choices, which contains incorrect information? (AUC 207 5.7)
A) Whenever possible, small fires in ties of an elevated railroad shall be handled by hand lines operated from the street below.
B) When an aerial or tower ladder must be raised to determine a particular situation at an elevated line, these ladders shall never be extended beyond the railing where they could be exposed over the track area to a moving train.
C) Small rubbish or tie fires in proximity to a raised aerial or tower ladder shall be extinguished, whenever possible, with a 2 1/2” line from the Transit stairway and track entry kept to a minimum.
D) The initial survey will be performed by an Officer before any members are committed to operations in a track area. Use extreme caution, as catwalks may be rotted, in disrepair, or eaten away from previous fires.
- C
5.7 ELEVATED ROADWAYS
5.7.1 Whenever possible, small fires in ties of an elevated railroad shall be handled by hand lines operated from the street below.
5.7.2 When an aerial or tower ladder must be raised to determine a particular situation at an elevated line, special precautions will be followed.
A. Aerial and tower ladders shall never be extended beyond the railing where they could be exposed over the track area to a moving train.
B. The initial survey will be performed by an Officer before any members are committed to operations in a track area.
C. Small rubbish or tie fires in proximity to a raised aerial or tower ladder shall be extinguished, whenever possible, with a 1¾” line from the aerial, or tower ladder basket and no track entry be attempted.
11) When a fuel spill on the street is close to a grating or main entrance of a subway station, we must try to stop the flow into these entrances by diking. Preferably, the proper order of diking is? (AUC 207 5.8 L)
A) 1. planking; 2. sand or earth; 3. charge several lengths of hose and encircle the fuel spill.
B) 1. charge several lengths of hose and encircle the fuel spill; 2. planking; 3. sand or earth.
C) 1. charge several lengths of hose and encircle the fuel spill; 2. sand or earth; 3. planking;
D) 1. sand or earth; 2. planking; 3 charge several lengths of hose and encircle the fuel spill.
- D
L. When a fuel spill is close to a grating or main entrance of a subway station, we must try to stop the flow into these entrances by diking. Preferably by sand or earth; if not, use planking. If none of these things are available, charge several lengths of hose and encircle the fuel spill. This should be followed by a layer of foam.
When a fuel spill is close to a grating or main entrance of a subway station, we must try to stop the flow into these entrances in order of preference using
SPiL:
1) Sand/earth
2) Planking
3) Lengths of hose
:
12) Several railroads have track sections that are serviced by a Dual Power System. This may be particularly found at junctions where different railroads (or formerly different railroads) share the same track facilities jointly. Of the following choices, which contains incorrect information regarding these systems? (AUC 207 6.6)
A) A track with a Dual Power System may be supplied simultaneously by an Overhead Catenary Line, usually 11,000 Volts AC current, and also a ground level 3rd Rail, usually 660 Volts DC current.
B) Officers in Command, requesting power removal from tracks with a Dual Power System, must communicate to ensure that power has been removed from both power systems for all affected tracks.
C) When power is reported to have been removed from an 11,000 Volt AC Overhead Catenary Line, members must be alert that there still remains a static electrical current in such lines. This static current still has the potential to dangerously shock anybody accidentally coming into contact with such a line.
D) Verification that Overhead Catenary Lines are safe after power has been reported removed, and that static current has also been removed, shall only be made through the Fire Department Dispatcher.
- D
A. When power is reported to have been removed from an 11,000 Volts AC Overhead Catenary Line, members must be alert that there still remains a static electrical current in such lines. This static current still has the potential to dangerously shock anybody accidentally coming into contact with such a line. Verification that such overhead lines are safe, after power has been reported removed, is made by railroad electricians employing special equipment and techniques at the site of operations. Such railroad electricians at the site of
operations can re-affirm to the Officer in Command that the static currents have also been removed.
13) Which safety consideration for operating in a subway is listed incorrectly? (AUC 207 7.2, 7.3, 7.4, 7.8)
A) Members crossing the third rail must not step on the third rail cover, but rather, over it.
B) Even with power off there are elements within the undercarriage electrical system that possess enough voltage to cause a shock. Contact with any undercarriage electrical components must be avoided.
C) A member directed to halt traffic shall use a light. The light is to be held waist high and moved in a wide, vertical motion of at least four feet.
D) A very dangerous condition exists when operations occur in proximity to a tunnel entrance or exit. Visibility will be extremely poor and must be counteracted by additional observers and extreme caution.
- C
- 4 A member directed to halt traffic shall use a light. The light is to be held chest high and moved in a wide horizontal motion of at least four feet. Train Operators are accustomed to seeing trackwalkers (inspectors) carrying lights. If this horizontal motion is not used, the firefighter might be mistaken for a walker and the train will not stop. Members must use extreme caution; stopping a moving train with a light is not assured. They shall ensure themselves a position of safety and warn any endangered members to stand clear.
14) A knowledgeable officer would be correct to identify which comments that reflect proper Department procedures and features of the subway system? (AUC 207 8.1, 8.1.1 C, 8.5.1)
1. Near the blue light, there is a power removal box, a telephone, and a dry chemical fire extinguisher. These are found along the right of way, approximately 600 feet apart.
2. The power removal box is operated by a pull down lever located inside the box. If forced to remove power, it is imperative to use the telephone near the blue light to inform the Desk Superintendent that power is to be removed and the reason why.
3. To operate the telephone at the blue light, remove the handset from inside the box and depress the button on the handset to talk. Then release the button to hear a reply.
4. The Power Removal Box will always be located directly under the blue light.
5. Whenever NYC Transit personnel determine that a Power Removal Box or the telephone is out of service, they will be covered with a bag to identify them as being out of service. This bag will be red, with white lettering, and it will state “Out Of Service.”
6. If a member encounters an out of service Power Removal Box, the member should use the associated telephone to contact the Rail Control Center (RCC) to request the removal of power. The member must identify him/herself and state the reason for power removal.
7. The blue light telephone does not ring; there is a buzzer mounted on the wall above the telephone that will intermittently activate.
A) 1, 2, 6, 7
B) 1, 2, 3, 4, 6
C) 1, 5, 6, 7
D) 1, 4, 5, 6, 7
- A
To operate the telephone at these locations, remove the handset from inside the box and depress the button on the handset, keeping it depressed at all times during the conversation. Releasing the button will terminate the call.
The Power Removal Box may not necessarily be located under the blue light, but it will be in proximity to it or across the tracks from it. This will require us to cross live third rails and be subject to moving trains.
Whenever NYC Transit personnel determine that a Power Removal Box or the Telephoneis out of service, they will be covered with a bag to identify them as being out of service. This bag will be white, with red lettering, and it will state “Out Of Service.
15) The senior member of Ladder 100 was discussing subway safety with the newer members of the company. He made an incorrect comment in which choice? (AUC 207 8.2, 8.3, 8.5.2 - 8.5.4, 9.3.3)
A) Contact shoes are pieces of metal that conduct electricity from the third rail to car motors. They stick out from both sides of the car near the wheels and if any contact shoe is on the third rail, all contact shoes of the car will be energized.
B) Some benchwalls are provided with cut outs (safety niches), which are indented spaces in the wall of the tunnel that provide room for a person to stand while a train passes by. When using a cutout, firefighters are required to use the reduced-profile maneuver for their masks and if a train should come by unexpectedly, they should go back to the cutout just passed, if it is clear.
C) All under river tubes of the NYC Transit System are equipped with dry standpipe systems and have siamese connections on each end of the tube. Water supply is via Fire Department pumpers only.
D) Each unit shall prepare an exact list of emergency exit locations within their 1st alarm response district and securely fasten this list to the subway emergency exit booklet issued to all units. Highlight and tab the pages in the emergency exit booklet where these locations are found.
- C
8. 5.2 All under river tubes of the NYC Transit are equipped with wet standpipe systems.
16) In the NYC subway system, emergency exits consist of stairways that lead up to the street from the track area and exit on sidewalks or ventilating towers near the river. All of the following choices contain correct information regarding these exits except? (AUC 207 8.8, 8.9)
A) A prism-shaped sign, or a cluster of 5 white lights, identifies emergency exits in subway tunnels.
B) Transit has installed intrusion alarms on all of their subway emergency exits. All units inspecting an emergency exit, or responding to an incident at an emergency exit, shall notify the Fire Department Dispatcher and communicate the exit number and location for transmittal to the Transit Control Center.
C) All companies have been issued Subway Emergency Keys with three different key shapes and a pry bar on the tool. The pry bar end is used to lift the emergency exit door, and to scrape out debris between the door and the door buck.
D) When encountering an emergency exit lock with other than the standard shapes, no Fire Department tool will open the exit and a NYC Transit representative must be requested to open the exit with the appropriate key.
- D
8.9 SUBWAY EMERGENCY KEYS
All companies are issued Subway Emergency Keys. There are three different key shapes and a pry bar on this tool. All the Subway lines (IND, BMT, IRT) emergency exits can be opened with this one key. The pry bar end is used to lift the emergency exit door, and to scrape out debris between the door and the door buck. However, some emergency exit locks are now appearing with other than the standard shapes. If this is the case, a pair of
vise-grips or pliers will have to be used to open the emergency door.
17) Two Battalion Chiefs discussing Fire Department operations and communications in subways agreed on three statements, and were able to identify which incorrect comment? (AUC 207 2.6.6, 4.3, 8.1.1 C)
A) The first arriving Chief Officer at the scene of a Transit Authority fire or emergency shall determine if the response of a Transit Authority representative is needed. If so, have the FDNY Dispatcher notify the Transit Authority Dispatcher and request that a “Transit Supervisor” respond to the scene. Ensure that the FDNY Dispatcher advises the Transit Authority Dispatcher of the exact location of the FDNY Command Post.
B) When a Chief will be operating in the tunnel, arrange for a Transit Authority Police Officer, or other employee equipped with a Transit Authority portable radio, to be assigned to the Chief in Charge operating in the tunnel. The radio can be used for communicating with the Desk Superintendent, and relay via telephone to the Borough Communications Office.
C) If the Truck Officer did not obtain the token booth telephone number prior to proceeding to the location of the fire or emergency, the Officer can use any blue light telephone to contact the Desk Superintendent and request to relay the blue light telephone number to the FDNY Borough Dispatcher, who shall relay the number to the Chief. The Chief can then have the token booth telephone used to call the blue light telephone to contact the Truck Officer.
D) To use a token booth telephone, which is a conventional telephone, request the token booth clerk to pass the telephone through the window. The Chief can also call the blue light telephone with his/her cellular telephone from the street, which is preferable over using the token booth telephone.
- D
The Chief Officer can call the blue light telephone with his cellular telephone from the street, but the token booth phone is the preferred method. The blue light
telephone does not ring, there is a buzzer mounted on the wall above the telephone that will intermittently activate.
18) On her first day as a Battalion Chief working in Battalion 45, BC Robinson was able to correctly identify herself as which designation on a response? (Comm 2-37) A) BC45F - FAST Group Supervisor B) BC45D - Division Task Force C) BC45L - Firefighter Locator Officer D) BC45R - High-Rise Roof Chief
- C
Battalion Chief C Communications Unit Leader D Tech Decon Task Force Leader Officer F Foam Coordinator G FAST Group Supervisor H Hi-Rise Roof Chief K Division Task Force L Firefighter Locator Officer P Staging Area Manager R Resources Unit Leader
High Rise Unit S Safety Officer T Transit Liaison N High Rise Nozzle V Ventilation Support Unit
19) According to the Department’s “Command and Control” policy, all of the following choices contain correct information with the exception of which choice? (C&C Ch 2 2.1.5, 2.1.6, 2.4.5)
A) Upon arrival of the assigned Deputy Chief, the first to arrive Battalion Chief shall be designated the Deputy Incident Commander or the Operations Section Chief.
B) Upon arrival of the assigned Deputy Chief, the first to arrive BC shall continue to manage the tactical operations of the incident under the supervision of the DC and both Chief Officers shall operate together for the duration of the incident. The DC and first to arrive BC shall remain at the ICP to ensure effective command and control.
C) A critical role of the first to arrive BC is to monitor HT Channel 2 (Command) for the transmission of critical messages, and ensure the timely response to such.
D) All units shall be informed when a particular sector/group has been established. Example: “Command to all units operating in exposure 2, Exposure 2 Sector has been established by Battalion 6, all transmissions are to go through the Exposure 2 Sector Battalion 6 unless urgent.”
- C
find out where C&C is
1) Two firefighters discussing the differences between incinerators and compactors identified which incorrect statement made by a fellow member? (TB Fires 7 1.1, 1.2 B, 1.3, 2.3 H Note)
A) New buildings (except hospitals and municipal buildings) are permitted to install only compactors. In existing buildings, an incinerator must either be converted to a compactor or be updated by adding a scrubber, an auxiliary gas or fuel burning mechanism and oversized fans.
B) Extension is unlikely but is much more probable in the case of an incinerator than in the case of a compactor, since incinerator chutes are designed for burning.
C) A compactor fire is a structural fire while an incinerator fire which does not extend or communicate from the shaft is an emergency. Operational priorities are different depending on the incident: Compactor - Put the fire out. Incinerator - Clear the blockage.
D) A fly ash collector is an area near the top of the incinerator vent shaft and can be as small as an enlarged area in the shaft or as large as a small room. It is always equipped with a means of access cleaning (generally a steel door).
- B
B. Extension is unlikely but is much more probable in the case of a compactor than in the case of an incinerator, since compactor chutes are not designed for burning. Therefore the operational priorities are different, viz:
1) Compactor - Put the fire out.
2) Incinerator - Clear the blockage.
2) At an incinerator emergency, every member has a duty to fulfill. All of the following choices contain an accurate description of these duties except? (TB Fires 7 2.1, 2.3 F, 2.4)
A) The Officer, FE team, and OV FF of the Ladder Company will generally operate inside the building to ventilate, search and locate the blockage.
B) The Roof FF proceeds to the roof to ventilate stairways and check the spark arrester for blockage.
C) It is very important that, before the Roof FF leaves the lobby, he/she ensures the stairwell door at the ground floor level is maintained shut to prevent a draft which will inhibit vertical ventilation.
D) The Ladder Company Chauffeur may be used to locate and check out the incinerator room or assist in search and ventilation of the building as ordered by the Officer.
- C
F. The roof firefighter of the ladder company proceeds to roof to ventilate stairways and to check spark arrester for blockage. As stated above, the bulkhead door can be opened and secured in order to vent stairways.
NOTE: It is very important that, before the roof firefighter leaves the lobby he chocks open the stairwell door at the ground floor level. This will provide for maximum draft and vertical ventilation when the roof bulkhead door is opened.
3) There are many ways to locate and mitigate an incinerator emergency. Of the following choices, which is incorrect? (TB Fires 7 2.2, 2.3)
A) If you open a chute door on a floor and smoke comes out, the blockage is generally below that floor. If instead, when you open it, a draft goes inward or there is little smoke, the blockage is generally above that floor or the blockage has freed itself.
B) One way to free the blockage includes using a hook, or reinforcing rod that is about 10 feet long and bent into an L shape, to push down the blockage from above. Some hopper frames can be removed to provide easier access to the chute.
C) Another method to free the blockage would be to tie a heavy weight to a rope and drop it from above. Do not drop anything which is not secured with a rope.
D) If the blockage cannot be freed using a hook, rod or tied-off weight, consider burning it off. (This is used only on incinerators).
- A
2.2 Locating the blockage.
A. If you open a chute door on a floor and smoke comes out, the blockage is generally above that floor. Refer to Reference #2
B. If instead, when you open it, a draft goes inward or there is little smoke, the blockage is generally below that floor or the blockage has freed itself. Refer to Reference #2
NOTE: If smoke is present on the uppermost floor, there may be a clogged or blocked spark arrester or fly ash collector. (See roof firefighter, below)
4) Which tactic listed below is incorrect in regard to incinerator operations? (TB Fires 7 3.2, 3.3, 4.1)
A) When opening a chute door, the member should be wearing full firefighting gear, including gloves, and eye shields down. The member should consider using a mask, if necessary.
B) When opening a chute door, stand to the side of the hopper door. If the door is hinged, stand on the hinged side.
C) At the chute door, eyes should be below the opening, and face turned away. Always stay clear of the opening, in case there is an explosion or an eruption of fire.
D) Generally, the Engine Company will stand-fast in the lobby with masks, roll ups and the standpipe kit. Some members may be used to assist the Ladder Company in search, vent, etc, however, generally the Officer and at least 1 member shall remain in the lobby.
- D
4.1. Engine companies shall be guided by the following:
A. Generally, the engine company will stand-fast in the lobby with masks, rolled ups and standpipe kit.
1) Some members may be used to assist the ladder company in search, vent, etc. However, generally the officer and at least 2 men shall remain in the lobby.
5) In order to familiarize her members with compactor units and chutes, Lt. Wall conducted a drill in quarters and pointed out which incorrect statement made by one of her members? (TB Fires 6.2, 6.5, 7.3, 7.5)
A) The photo-electric mechanism of a compactor unit operates on a delayed time principle and an object must block the beam for four seconds before the compactor starts. The time factor may be either consecutive or accumulative.
B) The type of compactor that FDNY units most frequently encounter is the “incinerator conversion,” installed at the base of the original incinerator chute. It is usually located in a separate room, accessible from the rear of the building.
C) An electrically operated sprinkler head in a compactor unit is thermostatically controlled to operate at approximately 135°F, and once activated, will flow until the temperature falls below 135°F.
D) In refuse chutes constructed in new construction, sprinklers shall be provided spaced not more than three stories apart for the height of the chute. They shall be recessed and so arranged that fused sprinkler heads may be readily replaced unless electrically operated.
- D
- 5 In refuse chutes constructed in new construction, sprinklers shall be provided spaced not more than two stories apart for the height of the chute. They shall be recessed and so arranged that fused sprinkler heads may be readily replaced unless electrically operated.
6) When there is fire in a compactor chute, all of the following unit and individual actions would be considered correct except? (TB Fires 7 8.2)
A) The first arriving Engine Company will proceed to one level above the burning material, stretch a line and operate into the chute to extinguish the fire.
B) The Officer and FE team of the Ladder Company will operate in the compactor room to first, locate the electrical shut off and shut power to the unit before operations commence.
C) The Roof FF will generally proceed to the roof to vent. After venting the roof, this member will search and vent stairways, floors, etc., as needed.
D) The OV FF’s duties will vary and will generally be as directed by the Officer to provide special tools in the compactor room or assist in search and venting, etc.
- D
B. OV operates with engine to provide access to the chute and to check for extension.
7) There are many hazards when attempting to extinguish a fire in a compactor chute or unit. Of the following choices, which contains incorrect information? (TB Fires 7 8.2 A, 8.3, 8.4, 9.4)
A) For a fire in the compactor chute, freeing the blockage, as you would in an incinerator fire, could result in a more serious situation in the compactor unit, because it is not designed for burning refuse. The possibility of extension is greater in the chute than in the unit.
B) When there is fire in the compactor unit, if it has not extended into the room, the Engine Company stretches a line to the first floor, and operates into the chute to extinguish the fire.
C) If fire has extended from the compactor unit to the compactor room, utilize firefighting tactics as you would for a cellar fire.
D) If hydraulic lines of the compactor unit rupture, the escaping flammable fluid adds to the potential of the fire. This would also create a slippery condition for members operating in the area.
- A
The possibility of extension is greater in the unit than in the chute.
