Lesson 1Human factors and organizational hazards: fatigue, communication gaps, subcontractor coordinationThis lesson analyses human and organisational factors causing hazards, like tiredness, communication breakdowns, and subcontractor teamwork issues in Nigeria. It highlights supervision, planning, and culture to cut down errors and unsafe habits among workers.
Tiredness, shift patterns, and workloadLanguage barriers and communication toolsTeamwork between multiple subcontractorsSupervision quality and role claritySafety culture and reporting habitsLesson 2Crane operations and lifting hazards: load paths, exclusion zones, rigging failuresThis lesson examines crane and lifting dangers, including load routes, no-go zones, and rigging breakdowns on Nigerian sites. It discusses lift planning, signals, weather limits, and gear checks to stop dropped loads and structural damage.

It stresses choice, checks, tethering, and safe use procedures to protect workers.
Choosing suitable tools and equipmentPre-use checks and upkeepTool guarding and emergency stopsTethering tools to prevent dropsSafe use of compressed air systemsLesson 8Electrical hazards: live work, temporary power, lockout/tagout failuresThis lesson details electrical risks during structural works in Nigeria, focusing on live wires, temporary power, and lockout or tagout failures. It emphasises planning, equipment choice, checks, and safe practices to prevent shocks, burns, and arc flashes.
Planning temporary electrical setupsChecks of cords, panels, and toolsAvoiding live work and safe distancesLockout and tagout on construction sitesGround fault and residual current devicesLesson 9Working at height hazards: scaffolds, edge protection, falling objectsThis lesson covers working at height dangers on structural frames in Nigeria, including scaffolds, edge guards, and falling objects. It reviews access systems, guardrails, fall arrest, and material containment to safeguard workers and the public.
