1. Under the New York City Administrative Code, a high-pressure
steam boiler is one that operates at a safety valve setting exceeding
which pressure threshold?
A. 5 psig
B. 10 psig
C. 15 psig
D. 25 psig
A high-pressure steam boiler in NYC is defined by a safety valve
setting exceeding 15 psig and a rating in excess of 10 horsepower. This
threshold aligns with ASME Section I, which governs power boilers
above 15 psig, whereas ASME Section IV limits low-pressure steam
boilers to 15 psig. This is a foundational licensing distinction.
2. Which ASME Boiler and Pressure Vessel Code section governs the
construction of high-pressure power boilers used for steam
generation above 15 psig?
A. Section I
B. Section II
,C. Section IV
D. Section VIII
ASME Section I contains the rules for construction of power boilers,
which include high-pressure steam boilers operating above 15 psig.
Section IV covers heating boilers (low-pressure steam and hot water),
Section II covers materials, and Section VIII covers pressure vessels.
Knowing the code section is essential for compliance and inspection.
3. According to the NYC Administrative Code, who must be present for
the operation of a high-pressure boiler?
A. A licensed master plumber
B. A certified refrigeration engineer
C. A licensed High-Pressure Boiler Operating Engineer
D. A registered architect
Section 28-413.1 of the NYC Administrative Code makes it unlawful to
operate a high-pressure steam boiler unless it is operated by or under
the direct and continuing supervision and in the presence of a person
holding a High-Pressure Boiler Operating Engineer license. This is a
core statutory requirement for lawful boiler operation in New York
City.
4. What is the minimum practical experience required for a high-
pressure boiler operating engineer license applicant who does not
hold a mechanical engineering degree or an approved apprenticeship
credential?
A. One year
B. Three years
, C. Five years
D. Ten years
The general experience pathway under NYC Administrative Code §28-
413.2 requires not less than five years of employment as a fireman,
oiler, general assistant, journeyman, boiler-maker, or machinist under
the direct and continuing supervision of a licensed high-pressure boiler
operating engineer in the city, within the seven-year period preceding
the application. Alternative pathways (engineering degree,
apprenticeship, marine engineer certificate) reduce or modify this
requirement.
5. What is the primary consequence of operating a high-pressure
boiler in NYC without a licensed High-Pressure Boiler Operating
Engineer present?
A. The boiler is automatically de-rated to low pressure
B. The operator must notify the utility company
C. The operation is unlawful under the NYC Administrative Code
D. The boiler must be shut down for a minimum of 30 days
NYC Administrative Code §28-413.1 explicitly states that it shall be
unlawful to operate any high-pressure steam boiler unless such boiler
is operated by or under the direct and continuing supervision and in
the presence of a licensed High-Pressure Boiler Operating Engineer.
Violations can result in penalties, stop-work orders, and liability.
6. The three elements necessary for combustion in a boiler are fuel,
heat, and:
