FDNY CoF – FuelOil Piping and Storage System P98 Ultimate
Exam
Question 1. **What chapter of the NYC Fire Code specifically governs fuel-oil storage tanks?**
A) Chapter 3
B) Chapter 6
C) Chapter 9
D) Chapter 12
Answer: B
Explanation: Chapter 6 of the NYC Fire Code contains the regulations for the installation, inspection, and
maintenance of fuel-oil storage tanks.
Question 2. **Which document must a P-98 holder keep on-site and make available for FDNY
inspection?**
A) Building Occupancy Permit
B) Certificate of Fitness (CoF) card
C) Electrical Safety Certificate
D) Fire-Alarm System Log
Answer: B
Explanation: The CoF card proves the holder is authorized to operate the fuel-oil system and must be
presented to FDNY upon request.
Question 3. **When is a permit required for the installation of a new fuel-oil tank in a high-rise building?
**
A) Only if the tank capacity exceeds 1,000 gal
B) Only for underground tanks
C) Whenever a tank is installed, regardless of size
D) Only when the tank is above the lowest floor
Answer: C
Explanation: NYC Building Code requires a permit for any new fuel-oil storage tank installation,
independent of capacity or location.

Question 4. **Which material is prohibited for fuel-oil supply piping in a new construction according to
the FDNY standards?**
A) Schedule 40 steel
B) Type L copper
C) Polyethylene (PE)
D) Stainless-steel 304
Answer: C
Explanation: Polyethylene is not approved for fuel-oil piping because it lacks the required temperature
and pressure ratings.
Question 5. **What is the primary purpose of an anti-siphon valve installed on a fuel-oil fill pipe?**
A) To regulate flow rate during filling
B) To prevent backflow of oil into the tank when the fill pipe is empty
C) To filter contaminants from the oil
D) To provide a manual shut-off for maintenance
Answer: B
Explanation: Anti-siphon valves stop oil from being siphoned out of the tank if the fill pipe becomes
submerged or empty.
Question 6. **A check valve in a fuel-oil system is installed to:**
A) Allow oil to flow in either direction as needed
B) Prevent reverse flow that could cause over-pressurization
C) Measure the temperature of the oil
D) Provide a visual indication of flow direction
Answer: B
Explanation: Check valves permit one-way flow, protecting the system from reverse flow that could
damage components.

Question 7. **Which type of shut-off valve is required to be automatic on a fuel-oil pump serving a
building over 10 stories?**
A) Manual ball valve
B) Motor-operated butterfly valve
C) Pneumatic-actuated fire-o-matic valve
D) Gate valve with handwheel
Answer: C
Explanation: FDNY mandates automatic fire-o-matic (thermal) shut-off valves on high-rise pump
installations for rapid isolation during fire.
Question 8. **The float switch in a day-tank is used to:**
A) Detect low oil level and start the pump
B) Measure oil temperature for viscosity control
C) Trigger an alarm when the tank is full
D) Shut off the burner when oil is absent
Answer: A
Explanation: The float switch senses low oil level and activates the pump to refill the day-tank, ensuring
continuous burner operation.
Question 9. **What is the recommended frequency for cleaning the primary fuel-oil filter in a
commercial boiler?**
A) Every 6 months or after 1,000 hours of operation, whichever occurs first
B) Every 2 years regardless of usage
C) Only when a pressure drop is observed
D) Every 30 days regardless of condition
Answer: A
Explanation: Regular cleaning at 6-month intervals or 1,000 hours helps maintain flow and prevents
burner clogging.
Question 10. **Which classification describes a fuel-oil tank located on the lowest floor of a building?**
, FDNY CoF – FuelOil Piping and Storage System P98 Ultimate
Exam
A) Above-grade tank, Class A
B) Below-grade tank, Class B
C) Inside-building tank, “Lowest Floor”
D) Underground tank, “Secondary Containment”
Answer: C
Explanation: The NYC Fire Code classifies tanks inside a building on the lowest floor as “Inside-building,
Lowest Floor” tanks, subject to specific clearance rules.
Question 11. **A double-walled underground storage tank (UST) must have interstitial monitoring.
What is the purpose of this monitoring?**
A) To measure oil temperature inside the tank
B) To detect leaks by sensing oil in the space between walls
C) To provide secondary fuel supply to the burner
D) To regulate venting pressure
Answer: B
Explanation: Interstitial monitoring detects oil that may have escaped the primary wall, providing early
leak detection.
Question 12. **What is the minimum height above grade for a vent pipe termination on an outdoor
fuel-oil tank?**
A) 2 ft
B) 4 ft
C) 6 ft
D) 8 ft
Answer: C
Explanation: The code requires vent terminations to be at least 6 ft above grade to prevent re-entry of
exhaust gases and rainwater.
Question 13. **During a fuel-oil fill, which method is considered the safest to prevent over-filling the
tank?**
Exam
Question 1. **What chapter of the NYC Fire Code specifically governs fuel-oil storage tanks?**
A) Chapter 3
