01Occupational Health and Safety
This domain checks whether you identify hazards before work starts, apply the hierarchy of controls, and name the specific regulation, PPE standard, or procedure that governs a task. Items are scenario-based: a galvanized weld in a basement, a curb on a roof, a ladder to a mezzanine.
489 words, about 2 min02Work Practices
This domain covers how a sheet metal worker plans, documents, and coordinates work: reading a work order, ordering material, getting a hoisting plan approved, and leaving the job with a clean paper trail. Expect questions on site coordination, load weights, material storage, and environmental responsibility.
494 words, about 2 min03Interpretation of Drawings, Specifications, and Layout
You are tested on reading a coordinated set quickly: which document governs, what the scale means, where the datum is, and how a duct or flashing detail is transferred from a benchmark to a real wall. Most items hinge on a dimension, a symbol, or a general note.
469 words, about 2 min04Pattern Development and Fabrication Layout
This domain tests whether you can turn a three-dimensional fitting into a flat pattern that fits: choosing the development method, finding true lengths, and adding the correct allowances for seams, joints, and bends. Parallel line: prisms and cylinders such as straight duct and square elbows.
489 words, about 2 min05Materials, Tools, and Equipment
The exam expects you to pick the right alloy and gauge for the service, and to know the capacity limits of the machine you are about to use. Items pair a service condition (pool air, kitchen grease duct, exterior coping) with a material, or a forming job with a machine rating.
474 words, about 2 min06Cutting, Forming, and Shaping Sheet Metal
Here the exam checks process knowledge: which cut gives a clean edge, what die and tonnage a bend needs, and how metal behaves when rolled, stretched, or shrunk. Items often ask why a part cracked, distorted, or sprang back.
484 words, about 2 min07Assembly, Fastening, and Joining
The exam tests whether the joint you choose holds the pressure, the vibration, and the service environment, and whether it is the specified joint. Expect items on seam types, fastener spacing, seal class, and welding coated or stainless steel.
478 words, about 2 min08Installation of Architectural and Building Envelope Products
This domain covers the weather side of the trade: roof drainage, flashing, wall cladding, soffit, fascia, and coping. Items test water control, thermal movement, and the fire, wind, and air-barrier requirements that decide whether an assembly passes inspection.
471 words, about 2 min09Installation of HVAC and Mechanical Systems
This section tests field judgement: pressure class, support spacing, clearances, damper access, and connections to equipment. The exam wants installation to the SMACNA manual and the specification, not to habit.
