COF P-98 COMPREHENSIVE QUESTIONS ANDDETAILED ANSWERS (ALREADY GRADED A+)
NEWEST EDITIONS 2024
1.- Where generally Fuel-oil is used in buildings? What purposes?*
Is used in Stationary Equipments,
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:
Polices, procedures and / or best practices recommended by the FDNY
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
6.- Supervision of Fuel-Oil Piping & Storage Operation
Shall be under the PERSONAL SUPERVISION of P-98 COF shall be?
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?
Weekly
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 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
14.- Oil Circulation in the System
What the suction pump do?
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
How many inches has to be the SUCTION LINE?
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?
A device that measures pressure below atmospheric pressure.
17.- Oil Circulation in the System
Excessive vacuum readings means?
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.?
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
20.- Oil Circulation in the System
Main Oil Storage Tank Dike
21.- Oil Circulation in the System
How operated the Main Fuel Valve?
The main fuel valve is electrically operated and will open or close the line leading to the
atomizer only for oil burners.
22.- Oil Circulation in the System
The Main Fuel Valve...
It will SHUT DOWN the burner system if there is a failure of ignition or combustion
23.- Oil Circulation in the System
Oil circulates through the piping system back to....?
The storage tank through the oil return line
, 24.- Oil Circulation in the System
For Safety is provide a Back Pressure Relief Valve
If the pressure becomes too great...
25.- Oil Circulation in the System
Where is located a Day Tank?
May be located throughout the building above the lowest floor
26.- Oil Circulation in the System
Day Tank Filter
27.- Oil Circulation in the System
Is required a Separate pump?
Yes, is required for each DAY TANK to supply each floor
28.- Oil Circulation in the System
In case of a leak in the piping.....?
Leak collector is provided. Leak collector is stored by the storage tank
29.- Oil Circulation in the System
Leak Collector Inside the Walls
30.- Oil Circulation in the System
Leak collector has a gauge?
Yes, It has a oil level gauge which shows the amount collected.
A gauge will show how much oil is inside a main storage tank/day tank
31.- Oil Circulation in the System
Leak Collector w/Oil Level Gauge
32.- Oil Circulation in the System
Level Gauge
33.- Oil Burner Operation
What is a combustion?
Combustion is the chemical union of the oxygen in the air with combustible elements in
fuel-oil (hydrogen and carbon).
34.- Oil Burner Operation
What is the end result of combustion?
The production of heat energy. Oil firing equipment is used to liberate heat energy from
fuel-oil.
35.- Oil Burner Operation
The principal components of the oil firing equipment?
Oil burners are the principal components of the oil firing equipment and provide the
means of supporting the process of combustion.
36.- Oil Burner Operation
What are the two principal elements of fuel-oil?
Carbon and hydrogen. During the combustion process, the carbon content of fuel-oil (about
85%) unites with the oxygen in the air and forms carbon dioxide and carbon monoxide.
The hydrogen content of the oil (about 14%) unites with the oxygen and produces water.
The objective is to have a complete combustion process
