01Core Units: Safety, Risk and Workplace Foundations
The core units are not a memory quiz on regulations; they test whether you can apply a safety reasoning cycle on any plant site. Know these concepts: the hierarchy of control (eliminate, substitute, engineer, administrate, then PPE last), hazard identification and risk assessment, incident and near-miss reporting, isolation and lock-out/tag-out (LOTO), pre-start checks, communication and signal systems, traffic management, and emergency response including first aid and firefighting basics.

Group A covers excavators, loaders, dozers, rollers, skid-steers and similar machines. You must understand pre-start and post-start inspections, fluid and tyre/track checks, safe operating envelopes, load charts and rated capacity, stability and centre of gravity, ground conditions and slope limits, exclusion zones and pedestrian separation, spotter and signal protocols, and shutdown/parking procedures.
302 words, about 2 min03Group B: Forklift Operations
Group B tests load handling and stability. Understand the stability triangle and longitudinal/transverse stability, the load centre and how load centre distance reduces rated capacity, mast tilt (back tilt when travelling with a load), fork spread and engagement, and the load chart on the data plate.
316 words, about 2 min04Group C: Elevating Work Platforms
