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?* - CORRECT ANSWER-*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: - CORRECT ANSWER-*Polices, procedures and / or
best practices recommended by the FDNY*
4.- The use of the word *shall* refers to: - CORRECT 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: - CORRECT ANSWER-*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? - CORRECT 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? - CORRECT
ANSWER-*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? - CORRECT ANSWER-*Weekly*
9.- *Licences & Certificates*
*No* oil burning equipment *may operated until?* - CORRECT 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? - CORRECT 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* - CORRECT ANSWER-
,12.- *Oil Circulation in the System*
What the *oil storage tank* do? - CORRECT 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*? - CORRECT ANSWER-*Is thin and light and is
easily pumped through the circulation system.*
14.- *Oil Circulation in the System*
*What the suction pump do?* - CORRECT 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*
How many inches has to be the *SUCTION LINE?* - CORRECT 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?* - CORRECT ANSWER-*A device that measures pressure below
atmospheric pressure.*
17.- *Oil Circulation in the System*
*Excessive vacuum readings* means? - CORRECT 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.?* - CORRECT 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* - CORRECT ANSWER-
20.- *Oil Circulation in the System*
*Main Oil Storage Tank Dike* - CORRECT ANSWER-
21.- *Oil Circulation in the System*
How operated the *Main Fuel Valve?* - CORRECT ANSWER-*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...* - CORRECT ANSWER-*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....? - CORRECT ANSWER-*The storage tank
through the oil return line*
24.- *Oil Circulation in the System*
For Safety is provide a *Back Pressure Relief Valve* - CORRECT ANSWER-*If the pressure
becomes too great...*
