FDNY COF P-98|Ques ons and answers | Updated
RATED A+ | NEW 2026
1.- Where generally Fuel-oil is used in buildings?
What purposes?
Is used in Sta onary 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 qualifica ons and comply w/ requirements applicable to such
cer ficate holder
- The P-98 COF is premise-related
3.- The use of the word should refers to:
Policies, procedures and/or best prac ces 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 Opera)on
Shall be under the GENERAL SUPERVISION of P-98:
A sta onary fuel-oil storage tank, related piping, that is installed on the lowest floor of the
building and transfer fuel-oil through piping to another sta onary 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
,6.- Supervision of Fuel-Oil Piping & Storage Opera)on Shall be under the PERSONAL
SUPERVISION of P-98 COF
Periodic Inspec on and Tes ng 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 & Cer)ficates
No oil burning equipment may operated un)l
a) Cer ficate of Compliance has been issued by NYCDOB
b) Air pollu on control code requirements NYCDEP
c) Permit for the Storage & use of fuel-oil issued by FDNY
10.- Licences & Cer)ficates
Pursuant to the New NYC Fire Code & Mechanical Codes stated that
The COF is required for all exis ng and new buildings where fuel is being transported from the
lowest levels to tanks or equipment on upper floors
11.- Oil Circula)on in the System
Diagram #1
The process of oil circula on from the tank at the lowest floor of a building to the burner on
the floor above such floor through the pump.
12.- Oil Circula)on in the System
Oil storage tank
Provides the supply of oil for combus on in the oil burner. It is inside a dike. In case of a leak
the diked area will contain the oil. In its normal condi on, #2 fuel-oil is thin and light and is
easily pumped through the circula on system
13.- Oil Circula on in the System
A Suc on pump
, 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 Circula)on in the System
The Suc)on Line
Has to be 6 inches from the bo?om 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 obstruc on in the suc on 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 Circula)on 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 igni on or combus on.
16.- Oil Circula)on 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 Circula)on 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 Circula)on in the System
Level Gauge
A gauge will show how much fuel oil is inside a main storage tank/day tank.
19.- Oil Burner Opera)on
Combus)on
