Alberta ABSA Boiler Exam Prep sample questions
Tap any question below to reveal the answer and a plain-English explanation.
Regs Under the Alberta Safety Codes Act, which organization is delegated authority to administer the Pressure Equipment Safety Regulation in Alberta?
A. Canadian Standards Association (CSA)
B. Alberta Boilers Safety Association (ABSA) ✓
C. Technical Standards and Safety Authority (TSSA)
D. Safety Codes Council of Alberta
Correct — B. ABSA is the authorized organization under the Alberta Safety Codes Act to administer the Pressure Equipment Safety Regulation, which covers the design, construction, installation, operation, and maintenance of boilers and pressure vessels in Alberta.
Safety A pressure vessel that receives heat from the direct application of combustion gases or flame is classified as which type?
A. Unfired pressure vessel
B. Vacuum vessel
C. Fired pressure vessel ✓
D. Heat exchanger
Correct — C. A fired pressure vessel uses an external combustion source (burner or furnace) to heat its contents directly. Unfired vessels obtain heat indirectly via steam, hot water, or electricity.
Ops Which welding defect consists of voids or gas pockets trapped within the weld metal during solidification?
A. Undercut
B. Incomplete fusion
C. Porosity ✓
D. Overlap
Correct — C. Porosity results from gases (hydrogen, oxygen, or nitrogen) becoming trapped in the weld pool as it solidifies. It weakens the weld by reducing the effective cross-sectional area and is typically caused by contamination, moisture, or inadequate shielding gas.
Roles Malleability is the property of a material that describes its ability to:
A. Resist fracture under impact loading
B. Spring back to its original shape after stress is removed
C. Be permanently deformed under compressive forces without fracturing ✓
D. Conduct heat efficiently
Correct — C. Malleability is the capacity of a material to deform plastically under compressive stress (rolling, pressing, or hammering) without fracturing. Gold and aluminum are highly malleable. Ductility, by contrast, describes deformation under tensile (stretching) forces.
Regs Which document must accompany a new boiler installation to confirm the design meets applicable code requirements before a certificate of inspection can be issued?
A. Manufacturer's warranty certificate
B. Operational audit report
C. Design registration certificate ✓
D. Maintenance agreement
Correct — C. A design registration certificate, issued by ABSA, confirms that the pressure equipment design has been reviewed and approved against applicable safety codes. It is required before a certificate of inspection can be issued.
Safety Bottom blowdown of a steam boiler is performed primarily to:
A. Test the operation of the safety valve
B. Remove sludge and sediment that accumulates at the lowest point of the boiler ✓
C. Increase the pH of boiler water
D. Reduce steam drum pressure quickly
Correct — B. Bottom blowdown removes suspended solids and sludge that settle to the lowest points of the boiler drum. It also helps maintain total dissolved solids within acceptable limits to prevent scaling and foaming.
Ops Which non-destructive examination (NDE) method uses high-frequency sound waves to detect internal flaws and measure wall thickness in pressure vessel components?
A. Magnetic particle testing
B. Dye penetrant testing
C. Radiographic testing
D. Ultrasonic testing ✓
Correct — D. Ultrasonic testing (UT) directs high-frequency sound waves into the material and measures reflections from discontinuities. It can detect sub-surface flaws and measure remaining wall thickness without damaging the component.
Regs What is the Maximum Allowable Working Pressure (MAWP) of a pressure vessel?
A. The pressure at which the safety valve first opens
B. The test pressure applied during hydrostatic testing
C. The minimum operating pressure required for function
D. The highest gauge pressure at which the vessel may operate continuously under specified conditions ✓
Correct — D. MAWP is the maximum gauge pressure permissible at the top of a completed vessel in its operating position for a specific temperature. Exceeding MAWP constitutes an unsafe condition that can lead to equipment failure.
