BLACK SEAL TEST QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT RATED A+
Question: According to the ASME Boiler and Pressure Vessel Code, what is the
maximum allowable pressure setting for a high-limit safety pressure control on a
low-pressure steam boiler?
Answer: ✔✔ 15 psig (Note: Anything operating above 15 psig falls under high-
pressure boiler regulations).
Question: True or False: By technical definition, a boiler is an open vessel in
which water is converted into steam under pressure through the application of heat.
True
False
Answer: ✔✔ False (Note: A boiler must be a completely closed pressure vessel to
allow steam pressure to build safely).
Question: True or False: According to New Jersey Administrative Code
(N.J.A.C.) rules, a school operating a boiler plant with a total interconnected
capacity of exactly 100 Boiler Horsepower (BHP) must have a properly licensed
operator present on the premises at all times when the building is occupied.
True
False
Answer: ✔✔ False (Note: Under N.J.A.C. guidelines, continuous attendance by a
licensed operator becomes mandatory when the total capacity exceeds 100 BHP).
Question: According to state jurisdictional boiler regulations, where must the
official boiler registration identification number or state stamp be permanently and
visibly located?
,Answer: ✔✔ On the front of the boiler shell or casing.
Question: A formal, continuous boiler operator's logbook must be actively
maintained in any plant that houses equipment exceeding what total capacity
threshold?
Answer: ✔✔ 100 Boiler HP
Question: If an operator's license is currently expired but remains in otherwise
good standing, within what maximum grace period can it still be renewed without
needing to re-take the state examination?
Answer: ✔✔ 3 years
Question: What is the maximum plant capacity limit that a Low Pressure Black
Seal license allows an operator to manage as a shift engineer?
Answer: ✔✔ No limit (Note: While a Black Seal license restricts the chief
engineer status to 500 HP, there is no capacity limit for operating as a shift
engineer under the supervision of a properly licensed Chief Engineer)
What is the maximum penalty for performing the duties of a boiler operator with
an expired license? -ANSWERS......$5,000.00
Where on the Certificate of Inspection would you find the State of New Jersey
jurisdiction number? -ANSWERS......upper left corner
What is the maximum temperature and pressure a hot water supply boiler can have
to be considered a low pressure boiler? -ANSWERS......160 psi at 250 degrees F
, The observed pressure of a heating system when it is in an idle or non-operating
mode is called: -ANSWERS......This is known as the static pressure of the system
The primary purpose of establishing a set of plant safety rules is to: -
ANSWERS......protect the workers and equipment
What are the four systems required to operate a steam boiler? -
ANSWERS......steam, feedwater, fuel and draft
Low pressure boilers shall comply with what section of the ASME code? -
ANSWERS......IV
What is the official ASME letter stamp used to denote low pressure heating
boilers? -ANSWERS......H
Which of the following statements regarding a hydronic heating system is accurate
in its description?
1. the water circulation must take the water from the boiler and move it through the
individual terminals or heating units where the heat is emitted and then return the
water to the condensate tank.
2. the water circulator takes the water from the feed pump discharge and moves it
through the individual terminals or heating units where the heat is absorbed and
any remaining steam turns to liquid then it is returned to the boiler to be reused
again.
3. the water circulator must take the water from the boiler and move it through the
individual terminals or heating units where the heat is emitted and then returns the
water to the boiler to be reheated.
4. none of the statements provides an accurate description for a hydronic heating
system. -ANSWERS......3
