Question 1
What is the primary purpose of holding an FDNY P-98 Certificate of Fitness?
A) To operate building fire alarm control panels and annunciator systems.
B) To supervise the transfer, storage, and piping of fuel oil within a building.
C) To oversee portable torch operations for cutting and welding.
D) To maintain and test commercial standpipe and sprinkler systems.
Answer: B
Detailed Rationale: The P-98 Certificate of Fitness certifies an individual to oversee fuel-oil transfer
operations, storage systems, and associated piping networks within buildings in accordance with the
New York City Fire Code.
Question 2
Under the NYC Fire and Mechanical Codes, when is a P-98 Certificate of Fitness legally mandated?
A) Only when a building stores over 10,000 gallons of heavy fuel oil outdoors.
B) For all buildings where fuel oil is transported from lowest-level storage tanks to tanks or
equipment on upper floors.
, C) Exclusively during temporary fuel-oil truck deliveries to residential basements.
D) Whenever an emergency backup diesel generator exceeds 50 horsepower.
Answer: B
Detailed Rationale: Pursuant to NYC Fire and Mechanical Code regulations, a P-98 C-of-F is required in
buildings where fuel oil is actively pumped or transferred from lower-level storage to upper floors (such
as roof tanks or day tanks supplying boilers and emergency generators).
Question 3
How long is a standard FDNY Certificate of Fitness typically valid before renewal is required?
A) 1 year
B) 3 years
C) 5 years
D) Indefinitely without renewal
Answer: B
Detailed Rationale: Certificates of Fitness issued by the FDNY are generally valid for a term of three
years, after which the holder must apply for renewal and meet any required qualifications.
Question 4
What is the legal distinction between the terms "shall" and "should" when interpreted under FDNY fire
regulations?
, A) "Shall" refers to recommended best practices; "should" is a mandatory requirement.
B) "Shall" denotes a mandatory requirement of the Fire Code or FDNY; "should" refers to
recommended procedures or guidelines.
C) Both terms carry equal legal weight as mandatory directives.
D) "Shall" applies only to temporary structures; "should" applies to permanent installations.
Answer: B
Detailed Rationale: In code language, "shall" indicates an absolute legal requirement enforced by the
FDNY, whereas "should" represents advisory guidelines, recommended procedures, or best practices.

Question 5
What is the primary function of the main fuel-oil storage tank located on the lowest level of a building?
A) To atomize fuel oil before it enters the combustion chamber.
B) To supply fuel oil for combustion in the oil burner, safely contained within a dike to contain
potential leaks.
C) To pressurize the domestic hot water supply throughout the upper floors.
D) To filter out all dissolved water prior to high-pressure injection.
Answer: B
Detailed Rationale: The main storage tank provides the continuous supply of fuel oil needed for boiler
or generator combustion and must be positioned within a diked or containment area designed to catch
spills or leaks.
, Question 6
Why must the fuel-oil suction line typically draw fuel from a minimum height of 6 inches from the
bottom of the storage tank?
A) To prevent heavy sediments, sludge, and accumulated water at the tank bottom from
entering the suction line.
B) To maintain maximum suction pressure and accelerate pump speed.
C) To comply with electrical grounding standards inside steel tanks.
D) To allow room for automatic submerged heating elements.
Answer: A
Detailed Rationale: Heavy sludge, dirt, and water settle at the bottom of fuel tanks. Keeping the suction
inlet elevated by approximately 6 inches prevents these contaminants from being drawn into the piping
and clogging burner strainers.
Question 7
What does an abnormally high vacuum gauge reading indicate during fuel-oil system circulation?
A) The fuel-oil pump is operating at peak efficiency.
B) There is an obstruction in the suction line, such as a clogged or dirty oil strainer.
C) The storage tank is completely overfilled.
D) The burner nozzle is operating with excessive draft pressure.
