FDNY S-13 Standpipe Systems Practice Exam (2026)
1. Which class of standpipe system provides 2½-inch hose connections intended for use by fire
department personnel only?
a. Class I
b. Class II
c. Class III
d. Class IV
✅ Correct Answer: a
• Rationale: Class I standpipe systems are designed with 2½-inch outlets specifically for use by the
fire department, as they require the use of heavy-duty hoses and specialized training. Class II
systems, with 1½-inch hose stations, are intended for use by building occupants.
2. In New York City, a standpipe system is required for all buildings over:
a. 55 feet in height
b. 75 feet in height
c. 100 feet in height
d. 50 feet in height
✅ Correct Answer: b
• Rationale: Under the NYC Fire Code, a standpipe system must be installed in any building that
exceeds 75 feet in height. These buildings are classified as high-rises.
3. A standpipe system that is attached to a water supply and requires no action other than opening a
hose valve to provide water is known as an:
a. Manual Dry Standpipe
b. Automatic Standpipe System
c. Semiautomatic Standpipe
d. Auxiliary Standpipe System
✅ Correct Answer: b
,2
• Rationale: An automatic standpipe system is connected to a reliable water supply that can meet
system demand at all times. It is always ready and does not require a fire department pumper
truck to supply the initial water pressure.
4. What is the primary purpose of a standpipe system?
a. To supply water to sprinkler heads
b. To provide a reliable water supply for manual firefighting
c. To detect and automatically suppress fires
d. To regulate domestic water pressure in high-rise buildings
✅ Correct Answer: b
• Rationale: Standpipe systems are installed in tall buildings to provide firefighters with a quick
and reliable water source for manual firefighting operations on various floors, eliminating the
need to stretch long hoses up stairwells.
5. The Certificate of Fitness holder (S-13) is allowed to work on:
a. Only manual standpipe systems
b. All standpipe systems except multi-zone standpipe systems
c. Only automatic wet standpipe systems
d. All standpipe systems, including multi-zone systems
✅ Correct Answer: b
• Rationale: The S-13 Certificate of Fitness qualifies an individual to inspect, test, and maintain all
standpipe systems in New York City. The exception is for multi-zone standpipe systems, which
require supervision by a person holding an S-14 Certificate of Fitness.
6. A red tag placed on a standpipe system's main control valve indicates:
a. The system is fully operational
b. The system is fully out of service
c. The system is partially out of service
d. The system has passed its annual inspection
✅ Correct Answer: b
• Rationale: A red tag is a critical signal. When placed on the main control valve, it means the
entire standpipe system is fully out of service. It should include the name of the servicing
company, the date it was taken out of service, and the estimated time for restoration.
7. What color disc is placed on the Fire Department Connection (FDC) to indicate that the system is
partially out of service?
a. Red
b. White
c. Blue
d. Green
✅ Correct Answer: c
,3
• Rationale: Color-coded discs are used on the FDC to quickly inform arriving firefighters of the
system's status. A blue disc means the system is partially out of service (e.g., a single floor or
zone is down), whereas a white disc indicates the system is fully out of service.
8. A planned removal from service of a standpipe system requires notification to the Fire Department
if it exceeds:
a. 4 hours
b. 24 hours
c. 8 hours
d. 48 hours
✅ Correct Answer: c
• Rationale: For planned maintenance, a standpipe system affecting no more than one floor can
be taken out of service without notifying the FDNY, provided it is fully restored within 8 hours.
Any longer or any unplanned outage requires immediate notification to the FDNY Borough
Dispatcher.
9. An "unplanned out of service" condition on a standpipe system must be reported to the:
a. Building owner and FDNY Borough Dispatcher
b. Local police precinct and building owner
c. FDNY Borough Dispatcher only
d. The insurance company and building owner
✅ Correct Answer: a
• Rationale: An unplanned outage, such as a major leak or an inoperative fire pump, is an
emergency. The procedure requires immediate notification to both the building owner and the
FDNY Borough Communication Office by the certificate of fitness holder or impairment
coordinator.
10. The device normally found on the exterior of a building, through which the fire department can
pump supplemental water into the system, is the:
a. Siamese Fire Department Connection (FDC)
b. Post Indicator Valve (PIV)
c. Main Control Valve
d. Roof Manifold
✅ Correct Answer: a
• Rationale: The Fire Department Connection (FDC), often a "Siamese" connection with two inlets,
allows FDNY pumpers to boost the water pressure and volume in a building's standpipe or
sprinkler system.
11. An OS&Y (Outside Screw and Yoke) valve is an indicating type of control valve. The valve is "open"
when the stem is:
a. Flush with the yoke
b. Extended outward from the valve body
, 4
c. At a 45-degree angle
d. Recessed into the valve body
✅ Correct Answer: b
• Rationale: The "OS&Y" valve is a key component in fire protection because its position is easily
visible. When the threaded stem is extended outward, the gate inside is open, allowing water to
flow. When the stem is flush with the yoke, the valve is closed, shutting off the water supply.
12. All records of system inspections, tests, and maintenance for a standpipe system must be kept on-
site for at least:
a. 1 year
b. 3 years
c. 5 years
d. 7 years
✅ Correct Answer: b
• Rationale: Proper record-keeping is a crucial part of fire safety compliance. All logs and records
pertaining to the standpipe system must be maintained on the premises for a minimum of three
years and be readily available for inspection by the FDNY.
13. A "blind shaftway" in a building refers to:
a. An elevator shaft without ventilation
b. A floor where an elevator cannot stop because there are no hoistway doors
c. An unlit stairwell
d. A section of the building without sprinkler coverage
✅ Correct Answer: b
• Rationale: In fire safety, a "blind shaftway" is a specific and important term. It refers to a floor
where the elevator does not have an opening (hoistway doors), meaning firefighters or
occupants cannot access that floor from the elevator. This is critical knowledge for building
evacuation and firefighting operations.
14. What does the "fail safe" feature on an electric lock mean?
a. The lock will sound an alarm if it fails
b. The door will automatically lock in the event of a power failure
c. The door will automatically unlock in the event of a power failure
d. The lock can only be opened by the fire department
✅ Correct Answer: c
• Rationale: "Fail safe" is a critical life-safety feature. In the event of a power outage or system
failure, a fail-safe lock will automatically release or unlock, allowing people to safely exit the
building and firefighters to enter without hindrance.
15. Rooftop dunnage is best described as:
a. Lightweight concrete used on roof decks
