Section 1: Regulations, Codes, and License Limits
Q1: Under the Maryland Stationary Engineers Act, what is the minimum boiler
horsepower (BHP) that mandates a Grade 1 license?
A) 300 BHP
B) 400 BHP
C) 500 BHP
D) 750 BHP
ANSWER ✓ C) 500 BHP. Maryland law clearly delineates license grades based on the
total horsepower of the equipment being overseen. A Grade 1 license is legally required
for any facility with a single piece of equipment or a combined plant capacity of 500
BHP or more .
Q2: A facility has a single high-pressure steam boiler rated at 450 BHP. Which license
grade is the minimum required to be the engineer in charge?
A) Grade 1
B) Grade 2
C) Grade 3
D) Grade 4
ANSWER ✓ B) Grade 2. The legal operating envelope for a Grade 2 license is 300–499
BHP. Operating a 450 BHP boiler with a Grade 3 license would be a violation of
Maryland law, subjecting the operator and facility to significant fines .
,Q3: According to Maryland regulations (COMAR 09.17.02.04), what are the specific
monitoring requirements for a new control system managing a 350 HP steam boiler?
A) The system must only monitor and indicate stack temperature.
B) The system must monitor, indicate, and record critical parameters.
C) The system is exempt from recording if a licensed operator is present 24/7.
D) The system must only record data if the pressure exceeds 150 PSI.
ANSWER ✓ B) The system must monitor, indicate, and record critical parameters. The
300 HP threshold is a critical dividing line in Maryland code. Systems under 300 HP
typically need only monitoring and indication. However, for systems at or above 300 HP,
the regulations mandate that the system must monitor, indicate, AND record data
points such as stack temperature, burner status, flame safety, and pressure/level .
Q4: What is the maximum civil penalty the Maryland Board of Stationary Engineers may
impose per violation for allowing an unlicensed individual to operate a boiler?
A) $1,000
B) $2,500
C) $5,000
D) $10,000
ANSWER ✓ C) $5,000. Under the Maryland Business Occupations and Professions
Article § 6.5-404, the Board can levy a civil penalty of up to $5,000 for each discrete
violation. This is in addition to potential criminal prosecution for subsequent offenses .
Q5: According to the 2026/2027 updates, what is a key change to ASME Section VIII
regarding pressure vessel design?
A) Introduction of a new Class 3 material.
B) Removal of Class 1 from Division 2.
C) A decrease in the standard design margin.
D) Mandatory use of titanium alloys.
ANSWER ✓ B) Removal of Class 1 from Division 2. The ASME 2025 Section VIII, Division
2, has removed the Class 1 design option, unifying the standard design margin at 2.4
times the ultimate tensile strength (UTS). This is a significant regulatory update for the
2026/2027 exam cycle .
Q6: Which Maryland regulation sets energy benchmarking and reduction targets for
large commercial buildings, impacting plant operations?
A) The Maryland Clean Air Act
B) COMAR 26.11.34
C) The Maryland BEPS (Building Energy Performance Standards)
D) The Maryland Occupational Safety and Health (MOSH) Act
, ANSWER ✓ C) The Maryland BEPS (Building Energy Performance Standards). The BEPS
applies to covered commercial buildings of 35,000 sq. ft. or more, enforcing strict Site
Energy Use Intensity (EUI) reductions. This directly impacts how a stationary engineer
manages and operates a plant's energy systems .
Q7: If you are a licensed Grade 1 Stationary Engineer in another state, can you operate a
boiler in Maryland without a Maryland license?
A) Yes, if your license is from a state with reciprocity.
B) Yes, for up to 30 days per year.
C) No, you must obtain a Maryland license.
D) Yes, if you are working under a Maryland-licensed professional.
ANSWER ✓ C) No, you must obtain a Maryland license. The Maryland Board of
Stationary Engineers does not currently have reciprocity agreements with any other
state or jurisdiction. Any individual providing stationary engineer services in Maryland
must hold a valid Maryland license of the appropriate grade .
Q8: What does the "R" stamp signify when applied to a boiler?
A) The boiler has been re-tubed.
B) The boiler is rated for a specific fuel type.
C) The boiler has undergone repairs in accordance with the ASME code.
D) The boiler is registered with the Maryland Department of the Environment.
ANSWER ✓ C) The boiler has undergone repairs in accordance with the ASME code. An
"R" stamp is a certification mark used by organizations that are authorized by ASME to
perform repairs and alterations to boilers and pressure vessels, signifying the work
meets ASME standards .
Q9: According to Maryland law, what is the minimum top clearance required for a boiler
that has manholes?
A) 2 feet
B) 4 feet
C) 5 feet
D) 7 feet
ANSWER ✓ C) 5 feet. To ensure safe access for inspection and maintenance, boilers
equipped with manholes must have a minimum clearance of 5 feet from the top of the
boiler to the nearest obstruction .
Q10: The Maryland Department of Labor requires that an application for a license exam
be processed through which vendor?
A) Pearson VUE
