Q&A
EXAM
1. Q: Per NFPA 25, the frequency for inspecting fire
department connections (FDCs) for visible damage is:
A) Monthly
B) Quarterly
C) Annually
D) Weekly
A) Monthly
Rationale: NFPA 25 mandates that FDCs be inspected monthly to
ensure swivel nuts are not damaged, plugs are in place, and there
are no visible signs of obstruction or mechanical damage.
2. Q: Gauges on dry pipe valves must be inspected how
frequently?
A) Daily
B) Weekly
C) Monthly
D) Quarterly
C) Monthly
Rationale: Water and air pressure gauges on dry pipe systems are
,required to be inspected monthly to verify that the air pressure is
being maintained at the proper level.
3. Q: When conducting a main drain test, the inspector is
primarily verifying:
A) That the alarm bell rings
B) That the water is clean
C) That there is no foreign material in the check valve
D) That there is no significant obstruction in the water supply
D) That there is no significant obstruction in the water supply
Rationale: A main drain test measures the flow of water from the
system riser. A significant drop in pressure (compared to the
original acceptance test) indicates an obstruction or a closed valve
in the water supply.
4. Q: Per NFPA 25, records of inspections, testing, and
maintenance must be maintained for:
A) 1 year
B) 3 years
C) 5 years
D) The life of the system
A) 1 year
Rationale: NFPA 25 requires that records be retained for a
minimum of 1 year, although it is industry best practice to keep
them longer. AHJs may require longer retention.
5. Q: If an inspector finds a "red tag" on a system, this
indicates:
A) A minor deficiency that needs monitoring
B) A non-critical deficiency
C) An impairment exists and the system is non-compliant or
,inoperable
D) The system is due for its 5-year internal inspection
C) An impairment exists and the system is non-compliant or
inoperable
Rationale: A red tag signifies a critical deficiency or an impairment.
The system is either not functional or does not meet code
requirements, requiring immediate action or a formal impairment
program.
6. Q: Gauges that do not return to zero when the system is
depressurized must be:
A) Recalibrated in the field
B) Replaced or recalibrated
C) Left in place if the error is less than 10%
D) Checked again in 6 months
B) Replaced or recalibrated
Rationale: Gauges that are stuck or do not return to zero are
unreliable. NFPA 25 requires they be replaced or recalibrated
against a calibrated gauge.
7. Q: The maximum interval for conducting a full flow test of
a fire pump is:
A) Monthly
B) Quarterly
C) Annually
D) 3 Years
C) Annually
Rationale: NFPA 25 requires an annual full-flow performance test
of the fire pump to ensure it can deliver 100% of rated capacity at
100% of rated pressure.
, 8. Q: Where a system is exposed to freezing temperatures, the
inspection frequency for low-temperature alarms is:
A) Daily
B) Weekly
C) Monthly
D) During cold weather (daily/weekly)
D) During cold weather (daily/weekly)
Rationale: While the code typically requires weekly inspections of
dry valves in cold weather, low-temperature alarms in pump
houses or enclosures must be checked frequently (daily or weekly)
during freezing conditions to prevent system failure.
9. Q: Obstruction investigations (internal pipe inspections) are
required every 5 years for which type of system?
A) Wet pipe systems only
B) Dry pipe and deluge systems
C) Pre-action systems only
D) All sprinkler systems
B) Dry pipe and deluge systems
Rationale: Dry pipe and deluge systems are prone to internal
corrosion and scale buildup due to trapped moisture after
operation. NFPA 25 requires obstruction investigations every 5
years for these systems.
10. Q: A "minor deficiency" per NFPA 25 is defined as:
A) A condition that poses a threat to life safety
B) A condition that does not immediately affect system
performance but requires correction
C) An impairment requiring a tag
D) A failed hydrostatic test
B) A condition that does not immediately affect system
