FDNY CoF Fuel Oil Piping and Storage System P98 Ultimate
Exam: Practice Questions & Code Rationales 2 versions
This specialized municipal preparation guide delivers comprehensive practice
questions, verified answers, and detailed regulatory rationales custom-designed for the
FDNY Certificate of Fitness (CoF) P98 examination. It provides exhaustive coverage of
the New York City Fire Code and Mechanical Code regulations governing the safe
operation, maintenance, and piping systems of fuel oil storage facilities. Certification
candidates and structural engineers will master critical safety parameters, transfer pump
mechanics, leak detection tracking, and emergency shutdown protocols to successfully
secure their official city licensing credentials.
1. What is the required frequency for testing the operation of the fuel oil transfer
pump?
A) Daily
B) Weekly
C) Monthly
D) Annually
Rationale: Fuel oil transfer pumps must be tested weekly to ensure they operate correctly
and deliver the required flow.
2. What is the minimum required thickness for steel fuel oil storage tanks?
A) 10 gauge
B) 12 gauge
C) 14 gauge
D) 16 gauge
Rationale: Steel fuel oil storage tanks must be at least 12 gauge to provide adequate
structural integrity and corrosion resistance.
,3. What is the purpose of a fuel oil tank's gauge?
A) To measure temperature
B) To indicate the amount of oil in the tank
C) To measure pressure
D) To filter impurities
Rationale: The tank gauge provides a visual indication of the oil level inside the storage
tank.
4. How often must fuel oil tank gauges be inspected?
A) Daily
B) Weekly
C) Monthly
D) Annually
Rationale: Tank gauges must be inspected weekly to ensure they are functioning properly
and accurately reflecting oil levels.
5. What is the maximum allowable water content in fuel oil storage tanks?
A) 1 inch
B) 2 inches
C) 3 inches
D) 4 inches
Rationale: Water accumulation in fuel oil tanks must not exceed 2 inches to prevent
corrosion and system malfunction.
6. What must be done if water is found in a fuel oil tank?
A) Ignore it
B) Remove the water immediately
C) Add more oil
D) Increase tank temperature
,Rationale: Water must be removed immediately from fuel oil tanks to prevent corrosion,
microbial growth, and system failure.
7. What is the primary purpose of a fuel oil tank's bottom drain?
A) To add oil
B) To remove water and sediment
C) To measure oil level
D) To vent gases
Rationale: The bottom drain allows for the removal of water and sediment that
accumulate at the bottom of the tank.
8. How often should fuel oil tank bottom drains be checked for water and
sediment?
A) Daily
B) Weekly
C) Monthly
D) Annually
Rationale: Bottom drains should be checked weekly to remove accumulated water and
sediment before they cause problems.
9. What type of valve must be installed on a fuel oil tank's bottom drain?
A) Gate valve
B) Globe valve
C) Check valve
D) Butterfly valve
Rationale: A globe valve is typically required on tank bottom drains to allow controlled
drainage of water and sediment.
, 10. What is the purpose of a fuel oil tank's vent alarm?
A) To measure oil level
B) To alert when the tank is being filled and prevent overfill
C) To filter impurities
D) To measure pressure
Rationale: The vent alarm sounds during filling to alert the operator and prevent
overfilling of the tank.
11. What is the minimum size for a fuel oil tank vent pipe?
A) 1 inch
B) 1¼ inches
C) 1½ inches
D) 2 inches
Rationale: Vent pipes must be at least 1¼ inches in diameter to allow proper air
displacement during filling and withdrawal.
12. What is the maximum allowable length for a fuel oil tank vent pipe?
A) 20 feet
B) As short as possible, with minimal fittings
C) 50 feet
D) 100 feet
Rationale: Vent pipes should be as short as possible with minimal fittings to reduce
resistance and ensure proper venting.
13. Where must a fuel oil tank vent pipe terminate?
A) Inside the building
B) Outside the building, above the roof line
C) In the basement
D) In the garage
