F02 F02 Standpipe and Hose Systems 2 — Questions and Answers
Question 1: At what pressure should water be available at the highest standpipe outlet during operation?
- 10 psi
- 25 psi (Correct answer)
- 100 psi
- 250 psi
Correct answer: 25 psi
NFPA 14 requires a minimum residual pressure of 100 psi at the highest most hydraulically remote standpipe outlet, but NYC rules require at least 65 psi at the topmost outlet; the commonly tested minimum is 100 psi at system design point.
Question 2: What color are standpipe hose connection caps typically painted in NYC to distinguish them from sprinkler connections?
- Yellow (Correct answer)
- Red
- Blue
- Green
Correct answer: Yellow
NYC standpipe hose connections are typically capped in yellow, while sprinkler system connections are capped in red to allow quick identification.
Question 3: How often must standpipe systems in NYC buildings undergo a full flow test?
- Monthly
- Every 5 years (Correct answer)
- Every 3 years
- Annually
Correct answer: Every 5 years
NYC requires full flow testing of standpipe systems every 5 years to verify system performance under demand conditions.
Question 4: What action should a Fire Guard take if they discover a standpipe hose is missing from its cabinet?
- Replace it with any available hose
- Note it in the logbook only
- Immediately notify building management and file a violation report (Correct answer)
- Close the cabinet and await the next inspection
Correct answer: Immediately notify building management and file a violation report
A missing standpipe hose is a fire code violation that must be immediately reported to building management and documented for corrective action.
Question 5: Which component prevents excessive pressure at lower-floor standpipe outlets in tall buildings?
- Check valve
- Pressure-reducing valve (Correct answer)
- Backflow preventer
- Gate valve
Correct answer: Pressure-reducing valve
Pressure-reducing valves are installed at lower-floor hose connections to limit outlet pressure to safe, manageable levels for hose operation.
Question 6: A dry standpipe system differs from a wet system in that it:
- Uses foam instead of water
- Has no Siamese connection
- Contains no water until the fire department charges it (Correct answer)
- Has smaller diameter pipes
Correct answer: Contains no water until the fire department charges it
Dry standpipe systems have no water in the pipes under normal conditions and must be charged by the fire department's pumper truck during an incident.
