✔✔Owner User Inspector - ✔✔An inspector commissioned by the department and
employed by a company pirating a pressure vessel within the Commonwealth and
meeting requirements set by KRS 236
✔✔PVHO - ✔✔Pressure Vessels for Human Occupancy
✔✔PVHO Pressure Rating Definition - ✔✔Under internal or external pressure
exceeding a differential pressure of 2 psi. Includes decompression or recompression
changers, high altitude chambers, hypo/hyperbaric chambers, and hyperbaric
stretchers.
✔✔Repair - ✔✔Work necessary to restore pressure retaining items to a safe and
satisfactory operating condition
✔✔Secondhand Boiler or Pressure Vessel - ✔✔Boiler or pressure vessel where the
boiler and ownership have been changed after initial use
✔✔State Special - ✔✔Boiler or pressure vessel that carries neither the ASME or NB
registration/symbol but has been accepted by the department
✔✔ASME Stamps - ✔✔New Boilers and pressure vessels shall be stamped with the
applicable certification mark of the ASME Boiler and Pressure Vessel Code
✔✔National Board Inspection Code Part 1 - ✔✔All boilers and pressure vessel
installations shall conform to this code
✔✔If pressure or temperature exceeds MADP device cannot function unless... - ✔✔1-
Temperature and Pressure controls on the boiler are permanently set to prevent
operation in excess
2- Safety Valves shall be installed on the boiler
✔✔ASME Code Section IX (9) - ✔✔Piping code for welded joints in pressure piping
installed by qualified professionals
✔✔Manufactures Data Report - ✔✔Report on all boilers of steel construction and
pressure vessels constructed in accordance with the ASME Boiler Code
, ✔✔Timeframe from inspection request to completion - ✔✔Inspection shall take place
within 7 days of request

registration number shall be assigned to the boiler and shall be a metal tag affixed near
the manufacturer's data plate
✔✔The boiler installation contractor - ✔✔Who is responsible for the quality of the
welding?
✔✔Welded Piping Joints - ✔✔Shall be visually inspected for full root penetration,
soundness of weld, freedom from undercutting,, cracking, or any other imperfections. If
visual shows potential defect, inspector may require further "non destructive" tests

- Non Amonia Systems with pipe dia of 2" or less and no welds
✔✔When documentation of materials used is provided to the inspector. - ✔✔When can
a pipe be painted prior to inspection?
✔✔True - ✔✔T/F: Design drawings and calculations shall be certified by a mechanical
engineer holding a PE certification with a background in boilers and pressure vessels
✔✔True - ✔✔The resetting of safety valves shall be done by a V-R stamp holder
✔✔21% - ✔✔Value over the MAWP that a pressure relief valve is capable of preventing
failure
✔✔Relieving capacity - ✔✔The minimum relieving capacity of the safety valve for safety
relief valves shall be equal to or exceed the MAWP
✔✔3 gauge cocks - ✔✔How many gauge cocks are required for manually fired boilers
within rang of the visible water glass
✔✔2' in all directions - ✔✔How much clearance should be allowed in for boiler
installation?
✔✔5' - ✔✔Clearance between the manhole opening and any wall, ceiling or piping?
