1. According to the Kentucky Boiler and Pressure Vessel Safety
Act, which entity has primary jurisdiction over the inspection,
installation, and repair of boilers and pressure vessels within
the state?
A. The Kentucky Department of Housing, Buildings and
Construction
B. The Occupational Safety and Health Administration (OSHA)
exclusively
C. The Kentucky Department of Housing, Buildings and
Construction, Division of Plumbing and Mechanical Systems,
acting through authorized inspectors and commissioned boiler
inspectors
D. Local county building code enforcement offices without state
oversight
Rationale: KRS Chapter 236 designates the DHBC as the
statutory authority for boiler safety; while OSHA covers
workplace safety, state law governs equipment certification and
contractor licensing; local offices enforce general building codes
but lack specialized boiler jurisdiction unless specifically
delegated.
2. A Kentucky boiler contractor wishes to perform alterations
on a high-pressure steam boiler. Before commencing work, the
contractor must:
,A. Notify the insurance carrier only after work completion
B. Obtain verbal approval from the facility owner
C. Submit detailed plans and specifications to the Chief Boiler
Inspector for review and approval, obtain necessary permits,
and ensure all welding procedures are qualified per
ASME/NBIC standards
D. Begin work immediately if licensed and notify inspector
within 30 days
Rationale: Alterations change original design parameters
affecting safety; pre-approval ensures compliance with
construction codes; permits create official record; procedure
qualification prevents weld failures; post-notification violates
statutory sequencing requirements designed to prevent unsafe
modifications.
3. When installing a new hot water heating boiler in Kentucky,
the minimum required safety devices include:
A. Pressure relief valve only
B. Temperature gauge and drain valve
C. ASME-rated pressure relief valve sized to boiler capacity,
low-water cutoff (if automatically fired), operating
pressure/temperature controls, and pressure/temperature
indicating gauges
D. Manual reset high-limit control only
Rationale: Multiple redundant safety layers prevent
catastrophic failure; relief valves protect against overpressure;
LWCOs prevent dry-firing/explosion; controls maintain safe
operating envelope; gauges enable operator monitoring; single-
device reliance insufficient per code requirements addressing
multiple failure modes.
,4. A boiler contractor discovers corrosion thinning below
minimum required thickness during internal inspection.
Appropriate action includes:
A. Applying external patch without engineering evaluation
B. Continuing operation until next scheduled outage
C. Removing boiler from service immediately, conducting
thickness survey, obtaining engineering assessment for
repair/replacement determination, and documenting findings
per NBIC guidelines
D. Increasing operating pressure to compensate for weakness
Rationale: Below-minimum thickness compromises structural
integrity risking rupture; immediate removal prevents
catastrophe; comprehensive survey identifies full extent;
engineering assessment determines viability; documentation
supports regulatory compliance; patches require NBIC-
compliant procedures; increasing pressure accelerates failure.
5. Under Kentucky regulations, boiler operator certification is
required for personnel operating:
A. All boilers regardless of size or pressure
B. Only nuclear power plant boilers
C. High-pressure boilers exceeding specified
horsepower/pressure thresholds as defined in KRS 236, with
certification levels corresponding to boiler complexity and
operating parameters
D. Low-pressure residential heating units exclusively
Rationale: Operator competency correlates with risk level;
high-pressure systems demand specialized knowledge; tiered
certification matches skill to hazard; residential low-pressure
units pose lower risk; statutory thresholds define applicability;
unqualified operation increases accident probability;
certification validates training/experience.
, 6. When performing hydrostatic testing on a repaired boiler in
Kentucky, test pressure should be:
A. Equal to normal operating pressure
B. Twice the maximum allowable working pressure (MAWP)
C. 1.5 times MAWP or as specified by manufacturer/code, held
for sufficient duration to inspect for leaks/deformation, with
proper venting and gradual pressurization procedures
D. 10% above operating pressure for quick verification
Rationale: Hydrotest verifies repair integrity beyond operating
conditions; 1.5x MAWP standard provides safety margin
without overstressing; duration allows leak detection; venting
prevents air entrapment hazards; gradual pressurization
protects components; operating-pressure tests insufficient to
validate repairs; excessive pressures risk damage.
7. A Kentucky boiler contractor employs welders for boiler
repair work. Welder qualifications must be maintained
through:
A. Initial qualification only with no renewal requirements
B. Employer’s internal assessment without documentation
C. Continuous performance records demonstrating regular use
of qualified processes, requalification after six months inactivity
or specific performance issues, and documentation per ASME
Section IX/NBIC requirements
D. Verbal confirmation of welding ability during hiring
Rationale: Welding skill degrades without practice; continuous
records prove ongoing competency; inactivity triggers
requalification preventing rusty-skills failures; documentation
enables audit verification; ASME/NBIC standards ensure
uniformity; initial-only qualification ignores skill decay; verbal
claims unverifiable; systematic tracking prevents defective
welds compromising vessel integrity.
