1. Under Minnesota law, which operating authority is associated with
a Second-Class Engineer, Grade B license?
A. Responsibility for all classes of boilers, engines, and turbines without
horsepower limitation
B. Responsibility for all classes of boilers not exceeding 100 boiler
horsepower, with additional shift-engineer and supervised-assistance
privileges
C. Responsibility only for low-pressure boilers not exceeding 50 boiler
horsepower
D. Responsibility only for hot-water supply boilers
B. Responsibility for all classes of boilers not exceeding 100 boiler
horsepower, with additional shift-engineer and supervised-assistance
privileges
A Second-Class Engineer, Grade B license authorizes the licensee to take
charge of and be responsible for the safe operation and maintenance of
all classes of boilers up to 100 boiler horsepower, operate as a shift
,engineer in a plant up to 500 boiler horsepower, or assist the shift
engineer under direct supervision in a plant of unlimited horsepower.
2. What is the minimum age generally required for an applicant
seeking a Minnesota Second-Class Engineer, Grade B license?
A. 16 years
B. 17 years
C. 18 years
D. 21 years
C. 18 years
Minnesota requires an applicant for a Second-Class Engineer, Grade B
license to be at least 18 years of age, in addition to satisfying the
applicable experience and examination requirements.
3. What minimum operating experience is generally required before
receiving a Minnesota Second-Class Engineer, Grade B license?
A. Six months
B. One year
C. Two years
D. Three years
B. One year
The statutory qualification for Second-Class Engineer, Grade B generally
requires at least one year of actual experience operating boilers, subject
to applicable educational or other statutory exceptions.
, 4. For Minnesota boiler engineer licensing purposes, which condition
defines a high-pressure steam boiler?
A. Steam pressure greater than 5 psig
B. Steam pressure greater than 10 psig
C. Steam pressure greater than 15 psig
D. Steam pressure greater than 30 psig
C. Steam pressure greater than 15 psig
Minnesota distinguishes high-pressure from low-pressure boilers at a
steam or other vapor pressure exceeding 15 psig.
5. A water or other liquid boiler operates at 170 psig and 220°F. How is
it classified under Minnesota's high- and low-pressure definitions?
A. Low-pressure because the temperature is below 250°F
B. Low-pressure because the pressure is below 200 psig
C. High-pressure because the pressure exceeds 160 psig
D. High-pressure only if both pressure and temperature exceed their
limits
C. High-pressure because the pressure exceeds 160 psig
For Minnesota classification purposes, a water or other liquid boiler is
high-pressure when its pressure exceeds 160 psig or its temperature
exceeds 250°F; only one threshold needs to be exceeded.
6. A liquid boiler operates at exactly 160 psig and exactly 250°F. Under
the statutory definition, which classification applies?
, A. High-pressure
B. Low-pressure
C. Special-pressure
D. Classification depends exclusively on horsepower
B. Low-pressure
The Minnesota definition uses pressure exceeding 160 psig or
temperature exceeding 250°F for high-pressure classification, so a boiler
operating exactly at both limits is not above either threshold.
7. How long is the Minnesota boiler engineer examination allotted?
A. 90 minutes
B. 2 hours
C. 2.5 hours
D. 4 hours
C. 2.5 hours
Minnesota Department of Labor and Industry specifies a 2.5-hour time
