Lesson 1Pedestrian exposure: loads travelling over people and walkway interactionsThis part looks at how walkers face crane dangers, like loads passing over folks, path clashes, and unseen areas, and covers setup, barriers, and rules to keep people and loads apart in Eritrean sites.
Mapping pedestrian routes and crane travel pathsRules for never traveling loads over personnelUse of barriers, exclusion zones, and signageSpotters and taglines near walkways and doorsManaging visitors and non-routine foot trafficLesson 2Environmental and workplace hazards: obstructions, poor lighting, slippery floorsThis part reviews site and work risks affecting crane safety in Eritrea, like barriers, dim lights, wet floors, and loud noise, and shows how to check, report, and fix these issues.
Identifying overhead and side obstructions to travelAssessing lighting levels at controls and load pathManaging floor conditions, spills, and housekeepingEffects of temperature, wind, and humidity indoorsNoise, visibility, and line-of-sight limitationsLesson 3Concurrent operations and multi-crane interactions when sharing a bayThis part handles risks when several cranes or jobs share a bay in Eritrea, like crashes, load blocks, and signal mix-ups, and covers planning, zoning, and talk controls for safe joint work.
Planning lifts when multiple cranes share a bayCrane zoning, interlocks, and anti-collision systemsCoordinating signals between multiple operatorsManaging simultaneous lifting and adjacent workSpotter roles during congested crane operationsLesson 4Load-related hazards: swing, snagging, unbalanced loads, tipping during liftThis part covers load risks like swinging, catching, uneven weights, and tipping, teaching how to predict load moves, plan rigging setups, and guide motion in all lift stages in Eritrean operations.
Causes and control of load swing and driftPreventing snagging on structures and equipmentCenter of gravity and unbalanced load indicatorsTipping risks for suspended and supported loadsUse of taglines and controlled accelerationLesson 5Maintenance and working at height hazards: access to runway, fall-from-height during maintenanceThis part deals with risks in crane upkeep and high work in Eritrea, like runway entry, falls, dropped items, and power slip-ups, and outlines safe entry, fall guards, and work permit rules.
Safe access to runways, walkways, and platformsFall protection selection and correct use on cranesLockout, tagout, and test-before-touch stepsPreventing dropped tools and loose materials aloftPermit-to-work controls for crane maintenanceLesson 6Human factors and communication failures: miscommunication, complacency, operator distractionThis part studies human issues like tiredness, distractions, overconfidence, and bad talk in Eritrea, showing how they lead to crane mishaps and ways to boost team work, signals, and safety mindset.
Recognizing fatigue, stress, and distraction in operatorsStandardizing hand signals and radio phraseologyManaging complacency during routine repetitive liftsBriefings, pre-lift huddles, and post-job reviewsDesigning controls to reduce human error likelihoodLesson 7Emergency and rescue hazards: dropped load scenarios, entrapment, electrical incidentsThis part handles crisis and rescue risks in Eritrean crane work, like fallen loads, trapped people, and shock events, and teaches planning, practice runs, and gear for safe handling without new dangers.
Planning for dropped load and near-miss eventsResponding to entrapment and crush situationsElectrical contact, arcing, and shock hazardsEmergency stop use and post-incident isolationRescue roles, equipment, and coordinationLesson 8Rigging and sling failures: wear, incorrect selection, improper inspectionThis part spotlights rigging and sling risks in Eritrea, like damage, wrong picks, and skipped checks, and shows how to spot flaws and fit rigging to the lift plan.
Recognizing wear, cuts, and broken wires on slingsSelecting slings and hardware for load and hitch typeTagging, identification, and capacity markingsInspection frequencies and removal-from-service rulesStorage, handling, and avoiding rigging misuseLesson 9Procedural and administrative gaps: outdated procedures, lack of pre-use checksThis part checks how old rules, missing pre-checks, and weak admin hide risks in Eritrea, and teaches building, updating, and enforcing useful crane rules and lists on site.
Identifying outdated or conflicting crane proceduresDesigning effective pre-use and shift inspection checklistsLinking crane procedures to risk assessmentsDocument control and version management for proceduresTraining and sign-off on new or revised proceduresLesson 10Crane system failures: hoist, trolley, bridge mechanical and electrical faultsThis part breaks down crane breakdowns in hoists, trolleys, bridges, and wiring in Eritrean setups, and shows how checks, tests, and fault reports stop sudden failures and unsafe states.
