Red Seal Sheet Metal Worker study plan

List the hierarchy of hazard controls and match at least 10 sheet metal shop and site hazards (pinch points, shear/brake amputations, silica dust, galvanized fume, falls, lockout) to the correct control level

Explain lockout/tagout and confined space entry rules well enough to describe, in writing, the sequence for servicing a power shear and for entering a duct plenum

Read a full set of architectural and mechanical drawings and correctly identify plan, elevation, section, detail, and schedule views without prompting

Decode a drawing's title block, revision block, scale, and line-type conventions, then state what each tells you about scope and build date

Convert 15 scaled dimensions to real dimensions across at least three common scales (1:50, 1:100, 1/4"=1'-0") with no more than one error

Extract duct sizes, elevations, and connection types from a mechanical drawing set and build a takeoff list of at least 20 line items

Interpret specification sections covering material gauges, sealant classes, hanger spacing, and pressure classifications and summarize each in your own words

Set up and mark out a full-size layout on the shop floor or a scaled sheet using centerlines, datum lines, and reference edges

Explain the difference between true length, foreshortened length, and true shape, and demonstrate each on a simple oblique connection

Produce a triangulation development for a square-to-round transition and verify the pattern by folding a paper model that fits the mating openings

Develop patterns for a 90-degree rectangular elbow, a radiused heel throat, and an offset transition using parallel line and radial line methods

Calculate bend allowance and setback for at least three material thickness/gauge combinations and apply them to a flat pattern

Compare galvanized steel, stainless steel, aluminum, and copper for formability, joining method, and corrosion behaviour, and justify a material choice for three different service conditions

Identify the hand tools and power equipment used for shearing, notching, rolling, and folding, and state one safety rule and one maintenance check for each

Match fastener and sealant types to joint conditions such as exterior wet, high-temperature, and dissimilar-metal contact

Describe the safe setup and operation sequence for a squaring shear, box-and-pan brake, slip roll, and rotary machine, including guard and clearance checks

Select the correct cutting method (snips, nibbler, plasma, shear) for five given scenarios and justify each choice by material, thickness, and cut quality

Explain how to join sheet metal by riveting, self-drilling screws, clinching, soldering, and welding, and state where each is and is not acceptable

Apply seam types (Pittsburgh, drive cleat, standing seam, button-lock) to the correct application and describe how each is formed and locked

Plan a sequence of assembly operations for a rectangular duct section so that fastening access is never blocked

Describe the components and installation sequence of a rainscreen or metal wall cladding system, including sub-girt, membrane, flashing, and fastener placement

Explain water management principles: drainage plane, capillary break, air barrier continuity, and why flashing laps run in a specific direction

Plan the installation of roof flashings, counterflashings, and coping so that each termination is water-shedding, and identify where sealant alone is unacceptable

Assess fall protection, ladder, and scaffold requirements for a two-storey exterior cladding job and list the controls you would put in place

Read a building envelope detail and mark up the air barrier, thermal barrier, and drainage plane on a printed section

Lay out a duct run from drawings, including offsets, transitions, and branch takeoffs, and select hangers at the correct spacing for the duct size and pressure class

Explain how duct pressure class and leakage class affect seam selection, sealant choice, and reinforcement spacing

Describe the installation requirements for fire dampers, smoke dampers, access doors, and fire-rated penetration closures and why each must be inspected before concealment

Assemble a flanged or slip-joint connection to specification and state the torque, sealant, and gasket requirements

Identify the clearance and accessibility requirements that affect where terminal units, VAV boxes, and volume dampers can be installed

Explain the purpose and sequence of duct pressure testing, including test pressure selection, temporary caps, and acceptable leakage criteria

Describe how to measure and adjust airflow at terminal units and what instruments are used for velocity, pressure, and flow readings

Outline the commissioning documentation trail from pre-functional checklist through functional performance test and final report

Diagnose three common balancing problems (starved branch, excess static pressure, damper hunting) and propose a corrective action for each

State the roles of the installing contractor, the balancing agent, and the commissioning authority during handover

Complete a full timed practice exam under exam conditions and record your score by domain

Re-study the two weakest domains using your own notes and re-test those areas

Recite from memory the key formulas and rules for bend allowance, hanger spacing, leakage class, and hazard controls

Review every missed question and write a one-sentence reason for each error so the pattern is visible

Build a final one-page reference sheet you can review in the days before the exam
