- While the City of New York has thousands of Hi-Rise buildings, these structures are not the only ones equipped with standpipes. Concerning standpipes, it would be incorrect to state: (9.1, 9.1.1)
a. Buildings that require a stretch of more than two lengths should be included in CIDS
b. The primary factors for the installation of a standpipe are the height and area of the
structure
c. Standpipes may be installed in areas where there is no access for fire department vehicles or where excessive distance precludes the stretching of hoselines directly off an apparatus
d. Structures where standpipes may be found include Hi Rise office buildings and residential buildings, shopping malls, bridges and tunnels, stadiums, piers and wharves.
A - Buildings that require a stretch of more than three lengths of hose should be included in CIDS for this specific reason.
- A standpipe system that contains no water and whose only source of supply is from a fire department pumper is known as what type of standpipe system? (9.2.1)
a. Manual system
b. Combination system
c. Manual dry system
d. Wet system
C - Wet systems contain water in the riser at all times supplied by city main, gravity tank, pressure tank, and/or fire pump (see Fig. 9-1). Combination systems consist of piping that supplies both hose connections and sprinklers. Most of these systems are “wet” and are of special concern because the water flow demands of both sprinkler heads and hoselines attached to the standpipe system require prompt augmentation by fire department pumpers.
Dry systems may be equipped with an automatic source of supply, but many contain no water and the only supply is from fire department pumpers. This latter type is called a “manual dry” standpipe system.
- The utilization of “Occupant Use” hose found on some standpipes is prohibited by FDNY members except in very rare circumstances. A unit would be operating correctly if they were to utilize this hose in which situation? (9.2.2)
a. An Engine Company operating alone bursts a length of hose in an immediate lifesaving situation.
b. A Rescue company at a fifth floor fire in an occupied multiple dwelling stretched the occupant use line due to the high heat and large volume of fire encountered. They used this line to back up the first hoseline after hearing the second and third engine companies would be seriously delayed
c. A ladder company officer on the floor above the fire ordered the occupant use line off the standpipe into the apartment above the fire to prevent fire from auto exposing to the floor above d. A ladder company operating remotely from an engine company utilized this hose while performing a primary search during an attempt to save lives
The stretching of occupant use hose by ladder and rescue companies operating remotely from an engine company, while performing searches, may be justified in an attempt to save lives.
- Siamese connections are color coded for ease of identification. Indicate which of the following siamese connections is painted with the correct color. (9.3.2)
a. Green – Standpipe
b. Aluminum – Perforated pipe or Non automatic sprinkler
c. Red – Combination sprinkler/standpipe
d. Yellow – Automatic sprinkler system
B - Red Standpipe-Green Automatic Sprinkler System - Aluminum Non-automatic Sprinkler or Perforated Pipe - Yellow - Combination Sprinkler/Standpipe
- An Engine Company lieutenant instructing members concerning properly supplying a standpipe system made the following statements. The lieutenant was not entirely correct in which one? (9.3.1 - 9.3.5)
a. Always supply a standpipe system with 2 1⁄2” of larger hose
b. Whenever possible, standpipe systems should be supplied by at least two different pumpers
c. It is permitted to supply a standpipe through either a siamese or a floor outlet
d. If possible, standpipe systems should be supplied by at least two independent siamese
connection
D - 9.3.3 Standpipe systems should always be supplied with 3 1⁄2” hose.
- Engine Company 169 has arrived first for a fire on the 12th floor of a 42 story fireproof multiple dwelling. The building is equipped with both a standpipe and an automatic sprinkler. The following actions were performed at this fire, one of which is incorrect. Which one was it? (9.3.7 - 9.3.9)
a. The first supply line was stretched to the standpipe siamese.
b. There was a separate pumper supplying the standpipe for each handline placed in service
c. If the first engine company is supplying both the standpipe and sprinkler system,
augmentation is required for the standpipe system only
d. All engine companies supplying the standpipe with approximately the same pressure to insure maximum efficiency
C - If the first arriving engine is supplying both the standpipe and sprinkler systems, the second and third arriving engine companies must stretch additional lines to augment both systems.
- Caps stuck in place, defective threads, and frozen female swivels are all problems which can cause delays in delivering water to a standpipe system. These problems can be solved by utilizing any of the methods given below, with which exception? (Fig. 9-2A – 9-2D)
a. Tap the swivels with a tool to loosen paint, polish, dirt etc.
b. Insert a 3”x3”x3” siamese into the standpipe siamese
c. Insert double 3” male, attach 3” double female swivel, and insert
d. Twist hose 4-5 right turns, insert, and turn to the left
D Twist hose 4-5 left turns, insert, and turn to the right
8. Engine Company 48 has stretched a hoseline off of a standpipe on the 40th floor for a fire on the 41st floor of a 51 story fireproof multiple dwelling. Because this unit has exceptionally well trained Engine Company Chauffeurs, they knew that the recommended pump discharge pressure for this fire was: (9.3.12) a. 400 psi b.350 psi c. 300 psi d. 325 psi
B Recommended Pump Discharge Pressures for Standpipe Operations Fire Floor Recommended Pump Discharge Pressure 1 – 10 150 psi 11 – 20 200 psi 21 – 30 250 psi 31 – 40 300 psi 41 – 50 350 psi 51 – 60 400 psi 61 – 70 450 psi 71 – 80 500 psi 81 – 90 550 psi 91 – 100 600 psi 101 – 110 650 psi
- Buildings constructed under the 2008 building code are required to have “High Zone” and “Low Zone” siamese connections. Concerning these types of standpipes, it would be correct to state which one of the following? (9.3.13, 9.3.14)
a. The Building Code requires buildings with standpipe risers over 500 feet in height to have separate High Zone and Low Zone siamese connections
b. The standpipe risers are interconnected
c. The High Zone riser is also known as “Express Piping” since it bypasses lower floors
d. The High Zone riser is required to have outlets on every fourth floor beneath its High Zone,
where it shall then have outlets on each floor
C - 9.3.13 Buildings constructed under the 2008 building code having a standpipe riser over 600 feet in height shall have separate “Low Zone” and “High Zone” siamese connections (See Fig. 9-4). These separate risers are not interconnected, so supplying the High Zone riser will not charge the Low Zone riser and vice versa. The connections shall be identified with signage stating either “Low Zone “or “High Zone” and indicate the floors they serve. The High Zone riser is also known as “Express Piping” since it bypasses lower floors
- Each engine company is required to carry a “standpipe kit”. Indicate which of the following tools are required to be carried in this kit? (More than one correct) (Sec. 9.4.1)
a. Door chocks, special adapters as required
b. Pipe wrench (minimum 18” in length), Spanner wrenches
c. 2 ½” x 2 ½” in line pressure gauge
d. Hand control wheel (Optional, not supplied by FDNY), 2 ½” controlling nozzle
A, B, C, D - Standpipe Kit. Each engine company shall carry a “standpipe kit” with the
following minimum basic complement of tools:
2 ½” controlling nozzle with 1 ⅛” main stream tip and 1 ½” x 2 ½”
increaser.
Hand control wheel(s) for outlet valve. (Note: Hand control wheels are
optional and not supplied by the Department.)
2 ½” x 2 ½” in-line pressure gauge.
Pipe wrench (minimum 18” in length).
Spanner wrenches.
Door chocks.
Special adapters as required. For example, some buildings may contain
floor outlet valves with non-New York City threads. Adapters for
connecting FDNY 2 ½” hose to National Standard Thread or National
Pipe Thread may be required.
- A firefighter from a busy engine company made the following statements concerning the stretching and operation of hoselines from a standpipe outlet. This member should get into the book, because his only correct statement was found in which choice? (9.4.1, 9.4.2, 9.4.4)
a. The initial hoseline from a standpipe outlet shall always be stretched from a floor below the fire unless approved by the Battalion Commander and entered into CIDS
b. The use of 2 ½” hose with a controlling nozzle and 1 1/8” MST is required due to the large volume of water it can deliver with minimal frictional loss
c. The controlling nozzle need not be pre-connected to one of the lengths brought into the building
d. Pressure reducing devices found on standpipes will not reduce the water flow and should not be removed
A - Note: Variations from stretching initial hoselines from standpipe outlets on a
floor below the fire due to building configurations shall be approved by
Division Commanders and entered into the CIDS program.
- The duties of the first arriving control firefighter can make the difference between a successful operation and one that does not go entirely well. These duties include all the following with which exception? (9.4.6 - 9.4.8)
a. Ensure a proper hookup to the standpipe as well as the removal of the pressure reducing device (PRD)
b. Continuously monitor the inline pressure gauge. This gauge should always be used to ensure correct nozzle pressure and a good fire stream
c. Realize that the pressure on the inline pressure gauge will increase when the nozzle is partially or fully shut down
d. Remain in the vicinity of the standpipe until relieved by the second to arrive control firefighter
D - The first arriving control firefighter shall remain at the standpipe outlet throughout the operation and communicate with the first arriving engine officer to ensure that adequate pressure is supplied to the nozzle. - The first arriving control firefighter should remain in close proximity to the standpipe outlet throughout the operation in case adjustments are needed.
- An engine company officer is preparing to advance with her unit at a fire on the 22nd floor of a 35 story Class E Hi Rise building. The unit has stretched 4 lengths of 2 ½” hose from the standpipe outlet on the 20th floor to the closed door of the fire apartment. The lieutenant was correct when she ordered the control firefighter to insure the outlet pressure on the inline pressure gauge is how many psi? (9.4.9)
a. 80 psi
b. 70 psi
c. 200 psi
d. 250 psi
A - At standpipe operations with a 2 ½” lead length with 1 ⅛” MST, the outlet
pressure is 70 psi for three lengths and 80 psi for four lengths.
- The FDNY classifies its Engine Companies by their pumping capabilities (Conventional, High Pressure, 3rd Stage). In regard to high pressure pumping operations, a firefighter would be incorrect to make which statement? (Add. 1, 1.3, 1.4)
a. High pressure pumping is defined as operating at a discharge pressure of over 250 psi
b. All FDNY pumpers are capable of delivering water at higher pressure
c. When high pressure pumping is necessary, the Incident Commander must be notified
d. Conventional engines shall not operate in pressures exceeding 200 psi unless an emergency conditions exist and they are ordered to do so by the Incident Commander
D - All engines, including conventional engines, are capable or providing pressures over 250 psi.
However, unless emergency conditions exist and they are ordered to do so by the IC,
conventional engines should not operate in pressures exceeding 250 psi. (Table 1 shows
the standard flow/pressure charts of FDNY engines).
- A lieutenant has ordered a probationary firefighter to get back to the apparatus forthwith to retrieve one of the high pressure fittings on their apparatus. The lieutenant should remind this firefighter that these fitting are noticeably heavier than regular fittings and are painted which color? (Add 1, 3.1)
a. Red
b. White
c. Black
d. Yellow
B
- You are a covering lieutenant working a 9x6 tour in E-207, a high pressure pumper. While operating at a Hi Rise fire at 1500 hours, you are ordered by the Incident Commander of the fire to begin high pressure pumping operations. Correct thoughts you had regarding this type of operation included all of the following with which exception? (Add 1, 3.1)
a. A safety zone was established at least 50 ft. around the high pressure engine and the supply line from the engine to the siamese connection.
b. You insured that all unused gates were closed and unused outlets on the apparatus were tightly capped
c. The supply line to the siamese connection was secured with a tether strap at the siamese connection only
d. A second ECC from a non pumping engine was ordered to assist in the operation. This ECC assisted in monitoring radio communications.
C - When high-pressure pumping operations are conducted,
Maintain safety zones of at least 50 feet around a working engine in all directions
including the high-pressure supply hose. If two connected lengths of high pressure
supply hose are in use, the safety zone may need to be expanded.
- You are the officer of the second engine company to arrive at a fire in a fireproof multiple dwelling on the 48th floor. Your engine is a hi-pressure pumper. The first engine, also a high pressure pumper has already started and is supplying the standpipe siamese at the required 350 psi. All high pressure pumping precautions are presently being observed at this fire. A correct action for you to perform with your unit can be found in which answer? (Add 1, 3.1-3.3)
a. Stretch a second supply line to the siamese and supply at 350 psi
b. Order the second supply line stretched to the first floor standpipe outlet
c. Do not augment the supply to the standpipe, as it is unsafe for more than one engine to supply a standpipe system at higher pressures
d. Report to the staging area on the floor below the fire, in the stairwell served by the standpipe being utilized by the operating handline
B - The standpipe system should be supplied by two engines. This will require more than
one high-pressure or 3rd Stage Engine to be assigned or special called to the incident if
pressures higher than 250 psi are required. When only one building siamese connection
is available, stretch the second supply line to the first floor outlet. Do not connect two
high-pressure supply lines to a single building siamese connection.
- An engine company Captain has arrived with his unit at a fire reported to be on the 101st floor of a mega hi rise building on 57th street in the borough of Manhattan. Due to the height of the fire floor, the Captain feels that 3rd stage pumping will be needed to establish a good stream on the units 2 ½” line. In regard to third stage pumping operations, it would be incorrect to state: (Add 1, 4.1, 4.2)
a. Pressures exceeding 600 psi will require the use of a third stage pumper
b. The officer of the first line can order the use of the 3rd stage
c. When third stage pumping is implemented, an additional third stage engine shall be assigned
d. Third stage engines are the preferred choice at operations requiring discharge operations over 500 psi
B - Only an IC at the rank of Battalion Chief or higher may order the use of the 3rd stage.
- A ladder company lieutenant was conducting a company drill at a construction site. The site has an air pressurized standpipe system. The lieutenant made the following statements concerning these types of standpipes, one of which was incorrect. Which one was it? (Add. 2, sec. 1.1 - 2.2)
a. They are required in buildings under construction upon reaching a height of greater than 75 feet in height and all buildings under demolition, regardless of height.
b. An alarm will sound when air pressure in the system drops below a predetermined (supervisory) pressure, or when the pressure in the system exceeds 25 psi.
c. Air pressure in the system must be removed prior to uncapping the siamese and supplying it with water
d. When an alarm sounds, all work in the site must cease, except concrete pouring operation in place
A - An air pressurized manual dry standpipe system is required at buildings under construction
upon reaching a height greater than 75 feet or buildings undergoing demolition with an
existing standpipe
- Other correct actions regarding air pressurized standpipe systems can be found in all but which of the following choices? (Add. 2, 2.4 - 2.10)
a. The location of the siamese connection is required to be marked by a sign and a red light at night
b. Screw in siamese caps are required. Breakaway or other non screw in types of caps are an indication of a non pressurized standpipe system
c. It is necessary to deactivate the air compressor prior to supplying the standpipe with water
d. The control firefighter, after reaching the floor outlet where he/she intends to hook up, should remove the cap, open the outlet control valve and wait for water to reach the outlet. This will expedite air removal from the system.
C - It is not necessary to deactivate the air compressor as it will shut off when the standpipe
is supplied with water.
- Brush fires occur in most parts of the city and can range in size from small nuisance fires to major multiple alarms. Weather is a controlling factor affecting the severity and incidence of brush fires. An incorrect factor as to when serious brush fires may occur can be found in which answer below? (AUC 151 3.2.1)
a. Winds in excess of 15 mph
b. High humidity
c. Little or no rainfall for the preceding three days
d. The higher the period without rain the greater the hazard
B - Low humidity.
- A lieutenant is responding to a multiple alarm brush fire in the borough of Richmond. While responding, she had the following thoughts, one of which was not entirely correct. Which one was it? (AUC 151 3.3)
a. The leading edge of the fire is known as the head
b. The rear of the fire is the side opposite the head
c. Looking at the fire from the head, the left side is called the left flank while the right side is known as the right flank
d. Fingers are long, thin sections of fire extending outward from the main blackened fire area
C - Looking at the fire from the rear of the blackened area, the left side is called the
left flank while the right side is called the right flank.
