1. What does the "Black Seal" boiler operator's license in New Jersey
authorize the holder to do?
A) Operate any high-pressure plant regardless of size
B) Operate low-pressure steam and hot-water boilers under state
limits
C) Design pressure vessels
D) Inspect boilers for code compliance


Correct Answer: B – The Black Seal is the entry-level state license
specifically for low-pressure boiler operation in New Jersey. High-
pressure plants require a Blue Seal or higher license. The license is
governed by N.J.A.C. 12:90 and established by N.J.S.A. 34:7-14.


Rationale: The Black Seal license does not authorize operation of
high-pressure plants, design work, or inspection duties. It is

,strictly an operator's license for low-pressure boilers as defined by
New Jersey regulations.


2. Low-pressure steam boilers in New Jersey are defined as operating
at a maximum of:
A) 30 psi steam pressure
B) 15 psi steam pressure
C) 25 psi steam pressure
D) 5 psi steam pressure


Correct Answer: B – Per N.J.A.C. 12:90 and ASME code, low-
pressure steam boilers are those not exceeding 15 psi. High pressure
is defined as steam exceeding 15 psi.


Rationale: This is a critical definition for the exam. Any boiler
operating with steam pressure above 15 psi is classified as high
pressure and requires a higher-level license to operate.


3. Hot water boilers are considered low-pressure in New Jersey when
they do NOT exceed:
A) 100 psi and 200°F
B) 160 psi and 250°F
C) 200 psi and 300°F

,D) 150 psi and 240°F


Correct Answer: B – Hot water boilers are considered low-pressure
when they do not exceed 160 psi and 250°F.


Rationale: Exceeding either the pressure limit of 160 psi or the
temperature limit of 250°F classifies the boiler as high pressure.
Both conditions must be met for the boiler to remain in the low-
pressure category.


4. What are the three criteria that define a low-pressure boiler in
New Jersey?
A) Steam ≤15 psi, Hot water pressure ≤160 psi, Hot water
temperature ≤250°F
B) Steam ≤30 psi, Hot water pressure ≤200 psi, Hot water
temperature ≤300°F
C) Steam ≤10 psi, Hot water pressure ≤100 psi, Hot water
temperature ≤200°F
D) Steam ≤20 psi, Hot water pressure ≤150 psi, Hot water
temperature ≤240°F


Correct Answer: A – The three criteria are: steam pressure not
exceeding 15 psi, hot water pressure not exceeding 160 psi, and hot
water temperature not exceeding 250°F.

, Rationale: These are the statutory definitions that establish the
boundary between low-pressure and high-pressure boiler
classifications in New Jersey.


5. What section of the ASME code do hot water heating boilers fall
under?
A) Section I
B) Section II
C) Section III
D) Section IV


Correct Answer: D – Hot water heating boilers fall under ASME
Section IV.


Rationale: ASME Section IV covers heating boilers, which include
both low-pressure steam and hot water heating boilers. Section I
covers power boilers, Section II covers materials, and Section III
covers nuclear vessels.


6. What section of the ASME code are low pressure boilers built to?
A) Section I
B) Section IV
