Lesson 1Vehicle and mobile plant hazards: forklifts and overhead cranesDis part dey break down hazards from forklifts, overhead cranes, and oda mobile plant, focusing on traffic management, operator skills, signaling, load security, and rules for shared spaces to stop collisions, crush injuries, and loads wey dey fall.
Traffic flow planning and exclusion zonesForklift stability, loads, and blind spotsOverhead crane pre-use checks and slingingPedestrian routes, crossings, and spottersParking, battery charging, and refueling areasLesson 2Chemical hazards: solvents, paint fumes, welding gases, metal dustDis part dey explain chemical hazards from solvents, paints, welding fumes, and metal dust, focusing on how dem enter body, health effects, monitoring, and layered controls like substitution, ventilation, safe storage, and picking right PPE and using am correct.
Solvent and paint components and exposure routesHealth effects of welding fumes and shielding gasesMetal dust generation, inhalation, and ingestion risksEngineering controls and local exhaust ventilationSafe storage, labeling, and PPE for chemicalsLesson 3Noise and vibration sources and effects in workshopsDis part dey talk about noise and vibration sources for workshops, dia health effects, how to check exposure, and control strategies, including engineering fixes, maintenance, admin limits, and picking and using hearing protection devices correct.
Main workshop noise and vibration sourcesHearing loss, fatigue, and other health impactsNoise surveys, dosimetry, and exposure limitsEngineering and administrative noise controlsHearing protection selection, fit, and careLesson 4Ergonomic hazards and manual handling during assembly and material storageDis part dey check ergonomic and manual handling risks during assembly and material storage, including lifting, pushing, awkward postures, and repetitive tasks, and e dey show methods for redesign, mechanical aids, and training to stop musculoskeletal injuries.
Task analysis for lifting and carrying activitiesUse of hoists, jacks, and mechanical handling aidsLayout design to reduce bending and reachingSafe storage heights and rack organizationTraining on body mechanics and team liftingLesson 5Electrical hazards: fixed machines, portable tools, temporary wiringDis part dey cover electrical hazards from fixed machines, portable tools, and temporary wiring, stressing shock, arc, and fire risks, lockout procedures, inspection routines, grounding, and working with qualified electricians for installation and repairs.
Electrical shock, arc flash, and burn mechanismsInspection of cords, plugs, and portable toolsLockout tagout for maintenance and cleaningSafe use of temporary power and extension leadsGrounding, bonding, and residual current devicesLesson 6Thermal and fire hazards: hot work, sparks, flammable liquids and vaporsDis part dey handle thermal and fire hazards from hot work, sparks, and flammable liquids or vapors, detailing ignition sources, fuel controls, hot work permits, fire watch duties, housekeeping, and emergency response planning for workshop operations.
Ignition sources in cutting, welding, and grindingControl of flammable liquids, gases, and vaporsHot work permits and pre-job area checksFire watch roles, equipment, and responseHousekeeping and segregation to limit fire spreadLesson 7Common physical hazards: sharp edges, moving parts, pinch points, falling objectsDis part dey review common physical hazards like sharp edges, moving parts, pinch points, and falling objects, explaining typical incident scenarios and practical controls including guarding, barriers, signage, and safe handling and stacking of materials.
Sharp edges, burrs, and sheet metal handlingMachine guarding and access to moving partsPinch points in presses, rollers, and clampsControls for falling objects and dropped toolsSignage, barriers, and safe walkwaysLesson 8Workforce factors: shift work, mixed experience levels, contractors and temporary staffDis part dey explore how workforce makeup and organization affect risk, covering shift work fatigue, different experience levels, language barriers, and integrating contractors and temporary staff into site rules, supervision, and safety culture.
Shift patterns, fatigue, and error likelihoodManaging mixed skill and experience levelsOnboarding and supervision of contractorsTemporary staff induction and task assignmentCommunication, language, and safety cultureLesson 9Overview of metal fabrication processes: cutting, grinding, welding, painting, assemblyDis part dey outline main metal fabrication processes and dia risk profiles, showing how cutting, grinding, welding, painting, and assembly steps connect, where hazards dey come from, and how planning, layout, and standard procedures reduce incidents and rework.
Typical workflow from raw stock to finished productCutting and grinding methods and related hazardsWelding and thermal cutting process risk overviewPainting, coating, and curing process safetySafe assembly, fit-up, and in-process inspections
