Lesson 1Human factors and organizational hazards: fatigue, communication gaps, subcontractor coordinationDis dey analyze human and organizational factors wey create hazards, including fatigue, communication gaps, and subcontractor coordination issues. E highlight supervision, planning, and culture to reduce errors and unsafe behaviors on site.
Fatigue, shift patterns, and workloadLanguage barriers and communication toolsCoordination between multiple subcontractorsSupervision quality and role claritySafety culture and reporting behaviorsLesson 2Crane operations and lifting hazards: load paths, exclusion zones, rigging failuresDis dey examine crane and lifting hazards, including load paths, exclusion zones, and rigging failures. E discuss lift planning, signaling, weather limits, and inspection of lifting gear to prevent dropped loads and structural impacts.
Lift planning and risk assessmentRigging gear selection and inspectionEstablishing load paths and exclusion zonesCommunication between operator and riggerWeather, wind, and stability limitsLesson 3Logistics and site traffic hazards: vehicles, deliveries, pedestrian segregationDis dey address logistics and traffic hazards from trucks, forklifts, and deliveries on structural sites. E cover traffic management plans, pedestrian routes, loading zones, and communication methods to prevent collisions and struck by incidents.
Site traffic management planningSegregated pedestrian walkwaysSafe loading and unloading zonesSpotters, signals, and communicationReversing vehicles and blind spot risksLesson 4Confined spaces and excavation adjacent hazardsDis dey review hazards in confined spaces and excavations near structural works. E discuss entry permits, atmospheric testing, shoring, access, and emergency planning to prevent engulfment, collapse, and asphyxiation on site.
Identifying confined spaces on sitesPermit to work and entry controlsAtmospheric testing and ventilationExcavation support and benching systemsRescue and emergency response planningLesson 5Health hazards: dust, noise, vibration, cement burns, CHP (chemical handling)Dis dey explore health hazards common in structural phases, such as dust, noise, vibration, and cement burns. E cover exposure assessment, controls, PPE, and safe chemical handling to prevent acute and chronic health effects.

E cover planning, housekeeping, reinforcement handling, pour sequencing, and inspection steps to prevent collapse or worker injury.
Slip and trip risks around poursManual handling of rebar and formworkFormwork design and load capacityInspection before and during concrete poursStripping formwork and backproppingLesson 7Tool and equipment hazards: falling tools, power tool guarding, compressed airDis dey focus on hazards from tools and equipment used in structural work, including falling tools, power tool guarding, and compressed air misuse. E emphasize selection, inspection, tethering, and safe operating procedures.
Selection of suitable tools and equipmentPre use inspection and maintenanceTool guarding and emergency stopsTethering tools to prevent dropsSafe use of compressed air systemsLesson 8Electrical hazards: live work, temporary power, lockout/tagout failuresDis dey detail electrical risks during structural works, focusing on live circuits, temporary power, and lockout or tagout failures. E emphasize planning, equipment selection, inspection, and safe work practices to prevent shock, burns, and arc flash.
Planning temporary electrical layoutsInspection of cords, panels, and toolsLive work avoidance and safe distancesLockout and tagout on construction sitesGround fault and residual current devicesLesson 9Working at height hazards: scaffolds, edge protection, falling objectsDis dey cover working at height hazards on structural frames, including scaffolds, edge protection, and falling objects. E review access systems, guardrails, fall arrest, and material containment to protect workers and di public.
