FDNY S13 Supervision of Standpipe Systems EXAM
Citywide COMPLETE QUESTIONS AND CORRECT
ANSWERS LATEST UPDATE THIS YEAR
FDNY S13 Supervision of Standpipe Systems (Citywide) The questions are based on NFPA 14, 3 RCNY
§505, §905, the NYC Fire Code, and FDNY study materials.
SUMMARIZED EXAM TOPIC COVERAGE (Point Form)
• Standpipe System Purpose & Definition – Deliver water for FDNY firefighting operations;
arrangement of piping, valves, and hose connections
• System Classifications – Class I (2½" outlets, FDNY use), Class II (1½" hoses, occupant use), Class
III (both), Combination (standpipe + sprinkler)
• System Types by Water Supply – Wet (always pressurized), Automatic Dry (air pressure, valve
opens on drop), Manual Dry (no water, FDNY supplies via FDC), Gravity-fed
• Building Height Requirements – Standpipes required in buildings exceeding 75 feet in height
(high-rise definition)
, Page 2 of 107
• Key Components – Risers (vertical piping), FDC/Siamese connection (red, street level), Hose
valves (angle valves), Pressure Reducing Valves (PRVs), Check valves, Fire pumps
• Pressure Requirements – Minimum 100 psi at most remote outlet during flow, residual; max
outlet pressure 175 psi
• Testing & Inspection – Daily visual inspection (when building occupied), Weekly fire pump
inspection, Annual main drain flow test, 5-year hydrostatic test (200 psi or 50 psi above working
pressure)
• Out-of-Service Procedures – Impairment coordinator; FDNY notification if >8 hours; Red tag for
OOS; Blue/White discs on FDC; Fire guard (hourly patrols)
• Records & Documentation – Logbook on premises; retain records minimum 3 years; inspection
date, findings, inspector name
• Color Codes – Red = standpipe FDC; Green = sprinkler FDC; Yellow = non-automatic system FDC
(silver/chrome)
, Page 3 of 107
• Operational Scenarios – Low pressure troubleshooting, valve position verification, obstruction
removal, freeze protection, pump failure response
250 RANDOM SCENARIO-BASED MCQS (With Answers & Rationales)
1. A firefighter reports low water pressure at a standpipe outlet on the 15th floor during a fire drill.
What should the S-13 Certificate of Fitness holder check FIRST?
A) Open all hose valves on lower floors to increase flow
B) Check pump operation and system valve positions
C) Drain the entire standpipe system immediately
D) Notify the building tenants of a possible water shortage
Answer: B – Pressure issues are most commonly caused by pump malfunction or valves that are partially
closed; these must be checked first .
2. Class I standpipe systems are intended for use by which group according to NYC Fire Code?
A) Building occupants only
B) Trained building fire brigades
C) Fire department personnel
, Page 4 of 107
D) Maintenance staff
Answer: C – Class I systems provide 2½-inch outlets specifically designed for FDNY use with heavy-duty
fire hoses .
3. A standpipe system that contains water under pressure at all times and requires only opening a hose
valve to provide water is classified as:
A) Manual dry standpipe
B) Automatic wet standpipe
C) Automatic dry standpipe
D) Manual wet standpipe
Answer: B – An automatic wet standpipe is constantly filled with pressurized water, making it the most
common and immediately available system type .
4. What is the minimum residual pressure required at the most remote standpipe outlet during a flow
test in a Class I system?
A) 65 psi
B) 80 psi
C) 100 psi
