5. If a building currently stores 700 gallons of fuel oil, what actions must be
taken to comply with FDNY COF P-98 certification regulations?
Leave the storage as is, since it is within regulations.
Reduce the storage to 660 gallons or less.
Increase the storage to 800 gallons.
Convert the fuel oil to a different type of fuel.
6. In a scenario where a fuel-oil tank is installed in a room with a one-hour fire
resistance rating, what safety concern arises regarding compliance with
FDNY regulations?
The installation would be compliant with FDNY regulations.
The installation would require additional ventilation.
The installation would not meet the required safety standards for
fire resistance.
