Lesson 1Mechanical hazards: rotating equipment, conveyors, forklifts, pallet storageThis section covers mechanical hazards from rotating equipment, conveyors, forklifts, and pallet storage. Learners will identify pinch, crush, and struck-by points, and review guarding, traffic control, and inspection practices to prevent serious injuries.

Learners will compare exposure durations, understand short-term and ceiling limits, and relate monitoring data to ventilation, PPE, and work practice controls.

Learners will practice reporting, trend review, and using findings to correct conditions before serious incidents occur.
Identifying and documenting near-miss eventsEarly symptoms of chemical or fume exposureObserving unsafe acts and at-risk shortcutsUsing checklists and simple observation toursTurning early indicators into corrective actionsLesson 4Chemical hazards: welding fumes, solvent paints, isocyanates, dustThis section reviews chemical hazards from welding fumes, solvent-based paints, isocyanates, and nuisance or toxic dusts. Learners will connect SDS data to routes of exposure, symptoms, and controls such as ventilation, PPE, and substitution.

Learners will identify ignition sources, review storage and ventilation rules, and apply hot work permits, housekeeping, and bonding and grounding practices.
Flammable liquid storage, transfer, and labelingCombustible metal and paint dust accumulationHot work permits for welding and cutting tasksIgnition sources from tools, sparks, and smokingVentilation and housekeeping to reduce fuel loadLesson 6Understanding the facility layout: production, paint booth, warehouseThis section teaches how to read the facility layout to spot hazards in production, paint booths, and warehouses. Learners will map workflows, traffic routes, and emergency paths to identify congestion, blind spots, and incompatible activities or materials.

Learners will identify awkward postures, forceful exertions, and repetition, and explore redesign, mechanical aids, and job rotation to reduce strain injuries.
Manual lifting of plate, bar, and finished partsRepetitive grinding, sanding, and tool vibrationAwkward postures at benches, racks, and boothsUse of carts, hoists, and lift tables as aidsJob rotation and microbreaks to reduce fatigueLesson 8Common physical hazards: cuts, slips, falls, struck-by, caught-betweenThis section covers common physical hazards such as sharp edges, slips, trips, falls, struck-by, and caught-between events. Learners will examine housekeeping, guarding, signage, and safe movement practices to reduce routine injury risks in the shop.

Learners will recognize shock, arc, and fire risks, and review basic lockout/tagout steps, inspection routines, and safe use of extension cords and GFCIs.
