Lesson 1Mechanical hazards: rotating equipment, conveyors, forklifts, pallet storageDis part cover mechanical dangers from rotating machines, conveyors, forklifts, and pallet storage. Learners go find pinch, crush, and hit-by points, and check guarding, traffic control, and inspection ways to stop big injuries.

Learners go compare how long exposure, understand short-term and ceiling limits, and connect monitoring data to ventilation, PPE, and work practice controls.

Learners go practice reporting, check trends, and use findings to fix conditions before big problems happen.
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, dustDis part review chemical dangers from welding smoke, solvent paints, isocyanates, and nuisance or toxic dust. Learners go connect SDS data to ways of exposure, symptoms, and controls like ventilation, PPE, and substitution.

Learners go find ignition sources, check storage and ventilation rules, and use 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, warehouseDis part teach how to read the facility layout to spot hazards in production, paint booths, and warehouses. Learners go map workflows, traffic routes, and emergency paths to find congestion, blind spots, and incompatible activities or materials.

Learners go find 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-betweenDis part cover common physical hazards like sharp edges, slips, trips, falls, struck-by, and caught-between events. Learners go check housekeeping, guarding, signage, and safe movement practices to reduce everyday injury risks in the shop.

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