FDNY COF P-98 Practice Test Study Guide Latest Update
2026 | Pass Exam Prep
1. If a building currently stores 700 gallons of fuel-oil above the lowest floor,
what steps should be taken to comply with regulations?
Increase the storage to 800 gallons.
Leave the storage as is, since it is not a fire hazard.
Store the excess oil in a basement.
Reduce the storage to 660 gallons or less.
2. If a primary control fails during operation, what immediate action should be
taken to ensure safety in the fuel-oil transfer system?
Shut down the oil burner
Perform a routine inspection
Activate the emergency control
Increase the fuel flow
3. Describe the purpose of having a tight container at the base of shafts for
fuel-oil transfer systems.
The tight container is used for storing excess fuel.
The tight container is primarily for aesthetic purposes.
The tight container allows for easy access to the oil supply.
The tight container prevents leaks and spills, ensuring safety and
compliance with regulations.
,4. In a scenario where the air atomization system fails during operation, what
immediate effect would this have on the combustion process?
Reduced emissions
Enhanced flame stability
Inefficient combustion
Increased fuel efficiency
5. What is the term used for the control that activates an oil burner?
Emergency control
Safety control
Secondary control
Primary control
6. What is the term used to describe the condition that can cause a fire in front
of a heating unit due to a malfunctioning oil cut-off valve?
Leakage
Overpressure
After-drip
Backflow
7. What is the source of the fuel used to fill fuel-oil tanks in buildings according
to the regulations?
Portable fuel containers
Direct delivery from a fuel truck
A primary storage tank located on the lowest floor
, A secondary storage tank on the roof
8. What is the required frequency for testing float switches in fuel-oil storage
tanks?
Weekly
Monthly
Annually
Biannually
9. If a building's fuel-oil transfer system does not have a tight container at the
base of the shafts, what potential issues could arise?
Reduced operational costs for fuel management.
Enhanced aesthetic appeal of the building's infrastructure.
Increased risk of spills and non-compliance with safety regulations.
Improved efficiency of the oil transfer process.
10. Why is it important for the suction line to maintain a specific distance from
the bottom of the tank?
To allow for better fuel flow rates.
To ensure the line is easily accessible for maintenance.
To prevent the suction line from drawing in sediments that can clog
the system.
To comply with aesthetic standards of the installation.
11. In a scenario where an oil burner is malfunctioning and poses a fire risk, what
immediate action should be taken regarding the emergency shutoff
controls?
, Notify the maintenance team and wait for instructions.
Activate the Emergency Shutoff control to stop oil flow.
Inspect the burner for damage before taking any action.
Continue operating the burner until it cools down.
12. If a building's fuel-oil storage tank has not been inspected for over a year,
what potential risks could arise from this oversight?
Increased risk of leaks and non-compliance with safety regulations.
Lower operational costs for the building.
No risks, as inspections are not critical.
Improved efficiency of the fuel-oil system.
13. What is the term used to describe the air that mixes with oil before it exits
the nozzle in a fuel-oil transfer system?
Combustion air
Ventilation air
Exhaust air
Atomizing air
14. Most fire codes require that portable fire extinguishers be inspected:
At least once each year.
At least every two years.
At least every five years.
At least every three years.
