Core concepts

Mixture type, layer, source, delivery documentation and conformity must match the approved design.

Concept 2

Exam cue: Plan unloading and laying so people stay clear of vehicle and hot-material hazards.
Concept 3
Burns, fumes, hot surfaces, reversing vehicles and moving plant require planned PPE, exclusion and communication.
Exam cue: Reject or escalate material outside the permitted condition.
