QUESTIONS WITH EXPLANATIONS



1. All heating, combustion, and cooking equipment shall be provided with
insulation or the building construction shall be fire protected, so that during
operation the surface of combustible construction materials will not be
raised to a temperature higher than _____.

 Correct Answer: 170°F
 Explanation: Combustible materials such as wood, insulation, or paneling can
ignite if exposed to excessive heat. Fire codes require that insulation or
protective barriers be installed to ensure that surfaces in contact with these
materials do not exceed 170°F, reducing the risk of fire or structural damage
during normal operation of oil burners or boilers.



2. Before a boiler can be placed in operation upon completion of
construction, it must have been ____ and an equipment use permit issued by
the commissioner.

 Correct Answer: Inspected and tested
 Explanation: Safety regulations mandate that all newly installed boilers are
thoroughly inspected for mechanical integrity, proper installation, and safety
compliance. Testing ensures that all safety controls, fuel supply, and combustion
systems are functioning properly. Only after inspection and testing can the
boiler legally be used with an official equipment permit.

,3. All boilers must undergo periodic inspections at least ____ including
chimney connections.

 Correct Answer: Once a year
 Explanation: Annual inspections of boilers and their associated chimney
systems are required to ensure safe operation. These inspections check for
corrosion, leaks, proper combustion, and adherence to fire codes. Regular
maintenance and inspection help prevent hazardous conditions, including
explosions, fires, and carbon monoxide buildup.



4. The owner of each boiler that is subject to periodic inspections must file
an annual ____ with the commissioner, specifying the location of each boiler
and arrangements for inspection.

 Correct Answer: Written statement
 Explanation: An annual written statement ensures the regulatory authority is
informed of all boilers in operation and can schedule inspections efficiently. It
also serves as documentation of compliance with safety and fire protection
regulations, ensuring accountability on the part of the boiler owner.



5. What three things must be tested for any fuel-burning and storage
installation before the system can be operated?

 Correct Answer:
1. Tightness of liquid fuel piping
2. Tightness of fuel oil storage tanks
3. Tightness of gas distribution piping
 Explanation: Testing for tightness prevents leaks that can lead to fire,
explosion, or environmental hazards. Liquid fuel leaks are particularly dangerous
in low PSI oil burner systems, as even a small leak can create a highly
combustible situation. Ensuring all piping and storage systems are sealed is a
critical safety step before operation.



6. What are instruction cards for oil-burning systems?

 Correct Answer: Cards giving complete instructions for care and operation that
are permanently located near the equipment
 Explanation: Instruction cards provide operators with quick, accessible
guidance on safe operation, startup, shutdown, and emergency procedures.
Permanently locating them near the equipment ensures that any operator or
technician can quickly reference them, reducing the risk of human error.

, 7. Every oil-burning installation that is not fully automatic or requires
preheating shall be operated by, or under, the direct supervision of a person
holding a ____ issued by the fire commissioner.

 Correct Answer: Certificate of Fitness (COF)
 Explanation: The COF ensures that the operator has received proper training
and certification to handle fuel-oil systems safely. Supervised operation is critical
for systems requiring manual preheating or other interventions, reducing the
risk of accidents or improper combustion.



8. After any fuel-burning equipment repair for which a licensed operator is
required, such operator shall also check the repairs and be ____ while the
equipment is started.

 Correct Answer: Present
 Explanation: Presence during startup ensures that any malfunctions or safety
issues can be addressed immediately. A licensed operator can monitor
combustion, pressures, and controls to confirm the system operates within safe
parameters.



9. What is abatement of air contaminants?

 Correct Answer: Compliance with the air pollution control code
 Explanation: Abatement involves taking steps to reduce or eliminate harmful
emissions, ensuring that combustion products do not violate environmental
regulations. Oil burners must operate in a way that controls smoke, soot, and
harmful gases such as CO or NOx, protecting both human health and the
environment.



10. What are the three equipment classifications and their temperatures for
the products of combustion at the point of leaving the equipment?

 Correct Answer:
1. Low Temp: 600°F or less
2. Medium Temp: 600°–1000°F
3. High Temp: 1000°F or greater
 Explanation: These classifications help determine the type of construction and
materials suitable for the combustion system and venting. Different temperature
