recommended by the FDNY*
4.- The use of the word *shall* refers to: - (ANSWER)*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: - (ANSWER)*A stationary fuel-oil storage tank,

Shall be under the *PERSONAL SUPERVISION* of P-98 COF shall be? - (ANSWER)*Periodic Inspection and
Testing of tanks and piping*
7.- *Maintenance Requirements*
Fuel-oil storage tanks and piping *shall be inspected* for any evidence of leaks? - (ANSWER)*Weekly*

,FDNY COF P-98 EXAM QUESTIONS AND ANSWERS 2025
9.- *Licences & Certificates*
*No* oil burning equipment *may operated until?* - (ANSWER)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? - (ANSWER)*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 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* - (ANSWER)
12.- *Oil Circulation in the System*
What the *oil storage tank* do? - (ANSWER)*Provides the supply of oil for combustion in the oil burner.
It's inside a dike. In case of leak the diked area will contain the oil.*
13.- *Oil Circulation in the System*
How is the #2 fuel-oil in its *normal condition*? - (ANSWER)*Is thin and light and is easily pumped
through the circulation system.*
14.- *Oil Circulation in the System*
*What the suction pump do?* - (ANSWER)*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.*
15.- *Oil Circulation in the System*
, FDNY COF P-98 EXAM QUESTIONS AND ANSWERS 2025
How many inches has to be the *SUCTION LINE?* - (ANSWER)*6 inches from the bottom of the tank for
sediments not to be absorbed*
16.- *Oil Circulation in the System*
What is the *vacuum gauge?* - (ANSWER)*A device that measures pressure below atmospheric
pressure.*
17.- *Oil Circulation in the System*
*Excessive vacuum readings* means? - (ANSWER)*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.*
18.- *Oil Circulation in the System*
Closing the *shut-off valve.?* - (ANSWER)Flow of oil *STOP*
*This permits the operator to clean the filter/strainer or to perform other maintenance*
19.- *Oil Circulation in the System*
*Main Oil Storage Tank on the Lowest Level* - (ANSWER)
20.- *Oil Circulation in the System*
*Main Oil Storage Tank Dike* - (ANSWER)
21.- *Oil Circulation in the System*
How operated the *Main Fuel Valve?* - (ANSWER)*The main fuel valve is electrically operated and will
open or close the line leading to the atomizer* only for oil burners.
