FDNY COF P-98 PRACTICE TEST 2026: VERIFIED
Q&A GUIDE| 100% ACCURATE ANSWERS
1.- Where generally Fuel-oil is used in buildings?
What purposes?
Is used in Stationary Equipment
Two purposes:
a) Fuel Emergency Generators
b) Fuel Equipment used to heat the building
2.- What COF is required to supervise the Fuel-oil transfer in the building from one floor to another?
- P-98 and maintain all qualifications and comply w/ requirements applicable to such certificate holder
- The P-98 COF is premise-related
3.- The use of the word should refers to:
Policies, procedures and/or best practices recommended by the FDNY, and may not be a codified
requirement.
4.- The use of the word shall refers to:
Requirement of the Fire Code or the FDNY
5.- Supervision of Fuel-Oil Piping & Storage Operation
Shall be under the GENERAL SUPERVISION of P-98:
A stationary fuel-oil storage tank, related piping, that is installed on the lowest floor of the building
and transfer fuel-oil through piping to another stationary fuel-oil storage tank, or fuel burning
equipment, installed above such floor
7.- Maintenance Requirements
Fuel-oil storage tanks and piping shall be inspected for any evidence of leaks
Weekly
Downloaded by FREDA SAINT B ()
,6.- Supervision of Fuel-Oil Piping & Storage Operation Shall be under the PERSONAL SUPERVISION of
P-98 COF
Periodic Inspection and Testing of tanks and piping
8.- Maintenance Requirements
Fuel-oil storage tanks shall have their float switches tested to ensure that they are in good working
order at least
Weekly
9.- Licences & Certificates
No oil burning equipment may operated until
a) Certificate of Compliance has been issued by NYCDOB
b) Air pollution control code requirements NYCDEP
c) Permit for the Storage & use of fuel-oil issued by FDNY
10.- Licences & Certificates
Pursuant to the New NYC Fire Code & Mechanical Codes stated that
The COF is required for all existing and new buildings where fuel is being transported from the lowest
levels to tanks or equipment on upper floors
11.- Oil Circulation in the System
Diagram #1
The process of oil circulation from the tank at the lowest floor of a building to the burner on the floor
above such floor through the pump.
12.- Oil Circulation in the System
Oil storage tank
Provides the supply of oil for combustion in the oil burner. It is inside a dike. In case of a leak the
diked area will contain the oil. In its normal condition, #2 fuel-oil is thin and light and is easily
pumped through the circulation system
13.- Oil Circulation in the System
A Suction pump
Downloaded by FREDA SAINT B ()
,Circulates the oil throughout the system. Dirt and sediment are present in the fuel-oil coming from
the oil storage tank. The oil filter removes most of these contaminants from the oil before the oil
reaches the burner's strainer.
14.- Oil Circulation in the System
The Suction Line
Has to be 6 inches from the bottom of the tank for sediments not to be absorbed. The vacuum gauge
is a device that measures pressure below atmospheric pressure. Excessive vacuum readings indicate
that there is an obstruction in the suction line (such as dirty oil strainer). When this occurs the flow of
oil can be stopped by closing the shut-off valve. This permits the operator to clean the filter/strainer
or to perform other maintenance
15.- Oil Circulation in the System
Main Fuel Valve
Electrically operated and will open or close the line leading to the atomizer only for oil burners. It will
shut down the burner system if there is a failure of ignition or combustion.
16.- Oil Circulation in the System
A Back Pressure Relief Valve
Oil circulates through the piping system back to the storage tank through the oil return line. A back
pressure relief valve is provided for safety if the pressure becomes too great. Day tanks may be
located throughout the building above the lowest floor
17.- Oil Circulation in the System
A Separate Pump
Required for each day tank to supply each floor. In case of a leak in the piping, leak collector is
provided. Leak collector is stored by the storage tank. It has a oil level gauge which shows the amount
collected
18.- Oil Circulation in the System
Level Gauge
A gauge will show how much fuel oil is inside a main storage tank/day tank.
