streams less than 30° fog. This distance is equal to approximately one and onehalf
(1½) lengths of hose.
• 25 feet on live 345 kV electrical components for 30° or greater fog streams.
This distance is equal to approximately one-half (½) length of hose.
• 125 feet on live 345 kV electrical components for all straight or solid streams
and streams less than 30° fog. This distance is equal to approximately two and
one-half (2 ½) lengths of hose.
NOTE: These minimum safe operating distances are from the tip of the nozzle to the nearest
energized electrical equipment in the direction of the stream.

Question 24

5. The minimum safe operating distance for applying water on energized or de-energized

   A. The exposed electrical contacts pose an electrocution hazard
   B. Once power is removed, capacitors no longer contain a deadly electrical charge
   C. Treat all capacitor fires as PCB incidents
   D. Small fires can be extinguished with Dry Chemical

Answer 25

6. B

Question 26

7. If a Battery Room fire were to occur at a substation, which of the following extinguishing
   agents may be utilized? (Add 2 5.5)
   A. Water or Carbon dioxide C. Dry Chemical or Carbon Dioxide
   B. Water or Dry Chemical D. Only Dry Chemical may be used

Answer 26

7. B

5.5 Battery Room Fire – Carbon dioxide should not be used as an extinguishing agent at
these fires. The plastic battery shell may crack when cold CO2 gas is applied to the fire
causing sulfuric acid to spill out and be vaporized by the heat. This creates a respiratory
hazard as the acid in the batteries is very corrosive. Dry chemical extinguishers will
work here as will water application from a safe distance.

Question 27

8. Exposed 3” electrical bus that runs overhead is a major hazard found at Con Ed substations
   as high voltages are carried on the outside skin of the bus. Members arriving at a Con Ed or other
   independent substation should know that when raising an aerial ladder or tower ladder bucket,
   they should maintain a safe clearance of? (Add 2 Section 6)
   A. 10 feet from 138 kV exposed bus, and 18 feet from 345 kV exposed bus
   B. 18 feet from 138 kV exposed bus, and 18 feet from 345 kV exposed bus
   C. 10 feet from the substation’s exterior fence line where 138 kV exposed bus exists, and 18
   feet from the substation’s exterior fence line where 345 kV exposed bus exists

   exists

Answer 27

8. D

Question 28

9. Sulfur Hexafluoride Gas (SF6 gas) is a colorless, odorless gas that can present an
   asphyxiation hazard in confined areas and below grade spaces. It is used to insulate and
   extinguish arcs in electrical equipment and is ______ times heavier than air? (Add 2 3.5)
   A. 3 B. 4 C. 5 D. 6

Answer 28

9. C

a. Thermal decomposition of SF6 gas produces:
1) Hydrogen Fluoride (HF) – This gas has a strong irritating odor similar to rotten
eggs. Prolonged exposure to HF gas will desensitize your sense of smell making
it undetectable. Inhaling HF gas can result in immediate or delayed onset
pulmonary edema.
2) Metal Fluoride powder – This white powder is a byproduct of thermal
decomposition of SF6 gas and is extremely corrosive to bare skin. The initial
sign of exposure would be reddening of the skin. Skin contact and inhalation
must be avoided.

Question 29

10. First alarm units arriving at a major substation transformer fire would be correct if they
    took which of the following actions? (Add 2 4.1, 4.2, 5.2, 6)
    A. Responded to the designated muster site, retrieved pertinent hazard information from the
    Lockbox located outside the substation, & met with the Con Ed White Hat
    B. Stretched a 3 ½” line to the sprinkler siamese that protects the transformers and
    immediately charged the system
    C. Avoided bringing metal tools into the substation, and did not allow any tools to project
    above their shoulders.
    D. Did not place any aerial ladder or any part of a tower ladder over any wall or fence.
    Portable ladders, as necessary, were placed only against solid, concrete walls

Answer 29

10. C

5.2 A 3½” supply line shall be stretched, but not charged, to the sprinkler siamese if present.
If requested by Con Edison White Hat, supply the siamese with water at the posted
pressure. Sprinklers if present protect only the transformers.

 When raising aerial ladders and tower ladder buckets, maintain an 18-foot safe clearance
horizontally from the substation’s exterior fence line and do not place portable ladders,
aerial ladders or tower ladder booms or buckets against or over the wall or fence.

4.2 Meet and consult with the Con Edison White Hat at the muster site. Have White Hat
retrieve information from the Lockbox located inside the substation.

   C. Queen Anne—May have old hot air ducts and / or dumbwaiter shafts
   D. Flat Roof—Have decorative peaks in the front without a window indicating flat roof
   construction

Answer 32

3. B

3.2 Cape Style Houses (Photos 1.5 & 1.6)
Cape houses usually come in two different styles. One is called an A frame cape and the
other a wide line cape. The A frame cape has a front entrance and usually a side entrance
with a stoop. The wide line cape will have a rear entrance and may have two window
dormers that are normally found facing the street. The presence of dormers usually
increases the likelihood of 2nd floor bedrooms. Portable laddering of these dormers can
be very difficult. The easiest exterior access to these rooms, via portable ladders, is
through windows that are found on the exposure 2 & 4 sides of the house. These homes
may have a full sized second floor or a dormer on the rear only.

Question 33

4. Engine 302 arrives at the scene of a fire on the second floor of a private dwelling where fire
   is showing out of a side window. How many of the following construction features found on the

6. A Lieutenant arriving at a fire in a private dwelling would be correct in which of the
   following sizeup consideration(s)? (Ch 2 2.4, 2.6, 2.7, Photos 2.3, 2.4)
   A. Exterior cellar entrances may be found on the front, rear or sides of PD’s and indicate a
   possible cellar occupancy
   B. An attic occupancy is indicated by an adequate height of 6 feet or more
   C. The lack of windows on the side of a PD combined with a secondary entrance that has a
   stoop on that same side of the house is indicative of a second floor apartment with two entrances
   to the stairway leading upstairs
   D. Porch roofs constructed of wood frame, aluminum or lightweight materials may provide a
   suitable platform from which to work
   E. Modern 3 family MD’s are often built with three separate entrances that have no common
   area — requiring PD tactics
   F. Balloon construction lacks fire stopping between floors on both interior and exterior walls
   G. Early collapse can

Answer 35

6. A, E

Question 36

7. When transmitting a 10-75 for a fire in a PD, which point(s) must also be transmitted if

Question 37

8. The primary consideration in the placement of the first hose line for access to a fire in a PD
   is via the entrance door that provides the quickest access to the fire area for fires in the?
   (Ch 3 1.6, 1.7)
   A. Cellar only C. Cellar and upper floors only
   B. Cellar and first floor only D. Entire building — on all floors

Answer 37

8. A
   hmmmm, I don’t know

1.6 The primary consideration for the placement of the first hoseline is through the front door
for the protection of both the interior stairs and the members conducting searches above
the fire.
1.7 The engine company officer shall announce via handi-talkie when a hoseline attack is to
commence. Advancing hoselines will cause conditions opposite the hoseline and above
to worsen, as the heat, fire, and steam are pushed by the force of the stream. Conditions
in areas behind, adjoining or above the operating hoseline must be monitored for sudden
possible deterioration due to the effects of hoseline advancement on the fire.
All members must be alert to fireground communications concerning hoseline placement
and the commencement of hoseline operations so that they may seek refuge if necessary.

Question 38

9. A company officer conducting drill on cellar fires was incorrect in which one of the
   following points he made at drill? (Ch 3 2.5, 2.6)
   A. The status and door construction of the interior cellar door is a critical factor and should be
   determined and communicated to the IC, if conditions permit
   B. A thermal imaging camera showing heat waves emanating across the first floor ceiling
   indicates the interior cellar door is open
   C. Smoke showing significant force and speed under pressure on the first floor indicates that
   the interior cellar door is open
   D. Only a Chief Officer may order an exterior hoseline operated into a cellar window

Answer 38

9. D

2.6 The Incident Commander should consider ordering an exterior hoseline to be operated
into a cellar window to allow for a quick knockdown when there will be a delay in
applying water from the interior. Some examples are as follows:
 Unable to gain entry to or advance the hoseline to the cellar level
 Unable to locate the interior cellar entrance
 A serious or advanced cellar fire

Question 39

10. A 1st due Ladder Company is operating at a cellar fire in a 2 ½ story PD where they have
    found the fire, but the engine has just suffered a burst length and cannot attack the fire. The Irons
    FF then gives a “Mayday” indicating he is trapped in the rear of the cellar by fire. The IC then
    orders the officer in charge of the second hose line to knockdown the fire from the exterior side
    cellar window due to the delay in applying water to the fire. In this situation, the company officer
    should be aware that the operation of the hoseline into a cellar window with members still in the
    cellar is? (Ch 3 2.6)
    A. Not permitted under any circumstances
    B. Not permitted unless the members in the cellar have an area of refuge in the cellar
    C. Not permitted unless the members in the cellar have a charged hoseline
    D. Only permitted in an emergency

Answer 39

10. D

Question 40

11. Engine companies operating at cellar fires would be correct to consider which point(s)
    below? (Ch 3 2.6 Note, 2.7.1)
    A. Proper placement of the first hoseline requires a coordinated size-up and communication
    between the first Engine and Ladder Officer
    B. The first hoseline should be stretched to the entrance door that provides the quickest access
    to the cellar in order to extinguish the fire
    C. In detached and semi-attached PD’s, the main entrance is usually the option that provides
    the quickest access to the cellar
    D. In attached structures, stretching the first line through a rear secondary entrance is
    generally the fastest option to apply water quickly on the fire
    E. At serious cellar fires, it is a good practice to have a precautionary charged line in position
    near the side of the building for emergency conditions that may develop

Answer 40

11. A, B, E

Question 41

12. First alarm units arriving at a fire in the cellar of a 2-story, detached, flat roof PD would be
    incorrect to consider which one of the following tactics? (Ch 3 2.7.2)
    A. High heat at the top of the interior cellar stairs precludes the descent of the first hoseline
    down the interior cellar stairs
    B. Questionable stability of the interior cellar stairs precludes the descent of the first hoseline
    down the interior cellar stairs
    C. When there is a serious fire condition in the cellar, the first hose line must advance through
    the main entrance to protect the first floor, and the second line should advance to extinguish the
    fire via a secondary entrance
    D. The safety of members is the paramount concern in making the decision to advance down
    the interior cellar stairs

Answer 41

12. C

2.7.2 The first hoseline should not be advanced down the interior cellar stairs unless
fire and stairway conditions permit for the rapid and safe descent of the
hoseline. Various factors, including the following, would preclude the descent of
the first hoseline down the interior cellar stairs:
 High heat conditions at the top of the stairs
 Questionable stability of the stairway
 Immediate availability of a second hoseline
 Initial size-up indicating a serious fire condition

Answer 43

14. D

2.7.4 When there is no other hoseline available and there is a delay in gaining access or
applying water to the cellar through the interior, the Incident Commander may
consider repositioning the first hoseline from the first floor into the cellar through
an exterior entrance.
The decision to reposition the first hoseline can only be made by a Chief Officer.
If possible, primary searches on all floors above the fire should be complete
before proceeding. The repositioning of the first hoseline must be carefully
coordinated and communicated to all units operating. The Incident Commander
should transmit an URGENT message utilizing the emergency alert button to
broadcast this to all members and ensure an acknowledgement from all
units/members operating in the interior.
For safety, all members operating on the first floor must be withdrawn before the
hoseline is moved and members operating on the upper floors may need to be
repositioned to a safe area, near a means of egress. Fire conditions above the fire
may become severe when this hoseline is repositioned.
