Lesson 1Mechanical hazards: pinch points, moving parts, lifting, crane and clamp failuresCovers mechanical hazards from moving parts, pinch points, and lifting in fabrication shops. Stresses guarding, safe use of clamps and fixtures, and planning crane and hoist moves to avoid failures.
Pinch points on rollers, presses, and drivesGuarding and interlocks on powered equipmentSafe use of clamps, jigs, and positionersRigging checks for cranes and hoistsHandling plate, beams, and structural shapesLesson 2Falls and work-at-height hazards: platforms, scaffolds, ladders, fall-from-platform scenariosLooks at fall risks when welding at height on platforms, scaffolds, and ladders. Covers access, edge protection, openings, dropped objects, plus planning tie-offs and rescue for high-level welding.

Learners spot ignition sources, combustibles, and controls like permits, fire watches, and hot work zones.
Sparks, spatter, and slag travel distancesIgnition of combustibles and hidden spacesCutting torch leaks and flashback risksHot work permits and area preparationFire watch duties and post-work monitoringLesson 5Chemical and respiratory hazards: welding fumes composition, solvent and paint residues, hexavalent chromium, ozone and nitrogen oxidesCovers chemical and breathing hazards from welding fumes, coatings, solvents, and gases. Learners link base metals and consumables to toxins and pick ventilation and respirators based on exposure.

Learners connect these to error risks and hazard spotting quality.
Fatigue effects on attention and coordinationTime pressure and production-driven shortcutsDistraction from forklifts and moving loadsCommunication in noisy, busy shop areasSupervisor role in managing human factorsLesson 7Optical and eye hazards: UV/IR radiation, visible flash, reflected arcs from shiny surfacesCovers eye hazards from welding arcs like UV, IR, visible light, and reflections off shiny surfaces. Stresses eye and face protection, curtains, safe distances, and checks on lenses and shields.
