FDNY S13 Supervision of Standpipe System (Citywide) Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- What is the primary purpose of a standpipe system?
a) To supply water for domestic use
b) To provide a means of delivering water to fire personnel in high-
rise buildings
c) To regulate building plumbing
d) To supply water to sprinkler systems only
Rationale: Standpipe systems are designed to allow fire personnel to
access water in buildings where fire hose operations from the street are not feasible. 1 / 4
- Which class of standpipe system is designed primarily for use by
trained fire personnel?
a) Class I
b) Class II
c) Class III
d) Class IV
Rationale: Class III systems combine features of Class I and II,
providing hose connections for both fire personnel and occupants.
- Where are standpipe hose connections typically located in high-rise
buildings?
a) Only at the ground floor
b) Within stairwells at each floor
c) In basements only
d) In mechanical rooms only
Rationale: Hose connections are installed in stairwells to ensure fire
personnel can quickly access water on each floor.
- What is the minimum residual pressure required at a standpipe outlet
- 25 psi
- 50 psi
- 100 psi
- 150 psi 2 / 4
when flowing 500 gallons per minute?
Rationale: Standpipe systems are required to maintain a minimum of
100 psi at hose outlets to ensure effective firefighting operations.
- Which NFPA standard governs standpipe systems?
a) NFPA 13
b) NFPA 72
c) NFPA 14
d) NFPA 25
Rationale: NFPA 14 establishes the requirements for the installation,
maintenance, and testing of standpipe and hose systems.
- How often must standpipe systems be inspected by the FDNY?
a) Every 6 months
b) Every 5 years
c) Annually
d) Monthly
Rationale: Annual inspections ensure that standpipe systems are
operational and compliant with regulations.

- 75 feet
- 100 feet
- 150 feet
Rationale: NFPA 14 requires a minimum of 100 feet of hose on Class I
systems to ensure reach to all fire areas.
- Where should pressure-reducing devices be installed in a standpipe
system?
a) At every hose connection
b) Only at the base of the building
c) On floors where pressure exceeds safe operating limits
d) In the sprinkler room only
Rationale: Pressure-reducing devices protect firefighters and building
systems from excessive water pressure in tall buildings.
- During a standpipe system flow test, what is the purpose of a
pitot gauge?
a) To measure temperature
b) To measure flow volume
c) To measure water pressure
d) To test water purity
