VERIFIED ANSWERS WITH RATIONALES JUST RELEASED
Alaska AK Sheet Metal Worker Journeyman & Trainee — Municipality of Anchorage Exam
The Municipality of Anchorage's published Journeyman Sheet Metal Exam information describes a 100-
question, two-hour exam covering code requirements for sheet-metal and gas-venting installations, with
a 70% passing grade. The listed study references include the Anchorage Administrative Code, 2018
International Mechanical Code (IMC), 2018 International Fuel Gas Code (IFGC), and Municipality
amendments. (Municipality of Anchorage)
10 MOST-TESTED EXAM COVERAGE AREAS
1. International Mechanical Code — General Requirements: General mechanical-code
requirements, definitions, permits, approved materials, equipment installation, access,
clearances, and inspection requirements.
2. Ventilation and Indoor Air: Mechanical ventilation, outdoor air, exhaust systems, intake
locations, exhaust discharge, makeup air, and ventilation for occupied spaces.
3. Duct Construction and Installation: Duct materials, joints, seams, supports, hangers, fittings,
transitions, dampers, flexible ducts, plenums, and duct installation requirements.
4. HVAC Equipment and Appliances: Furnaces, boilers, heat-producing equipment, air-
conditioning equipment, appliance installation, service access, clearances, combustion
requirements, and equipment connections.
5. Chimneys, Flues, and Venting: Appliance vents, chimneys, vent connectors, termination
requirements, clearances, draft, common venting, and prohibited venting practices.
6. International Fuel Gas Code — General Requirements: Gas piping, approved materials,
appliance connections, shutoff valves, regulators, pressure requirements, testing, and
installation safety.
7. Gas Venting and Combustion Air: Combustion-air openings, confined spaces, natural draft
appliances, mechanical combustion air, vent sizing, vent termination, and dilution air.
8. Gas Piping Systems: Pipe sizing, fittings, joints, supports, corrosion protection, sediment traps,
shutoff valves, pressure testing, and appliance connections.
9. Safety, Fire Protection, and Clearances: Fire dampers, smoke dampers, fire-resistance
requirements, clearance from combustible materials, access panels, protection of openings, and
safe installation practices.
10. Anchorage Requirements and Local Code: Anchorage Administrative Code requirements,
Municipality amendments, local licensing/qualification requirements, inspection requirements,
and the relationship between the local rules and adopted IMC/IFGC provisions. (Municipality of
Anchorage)
