Task analysis, people, equipment, materials, environment, sequence, competence, communication and monitoring.
Exam cue: Identify the workplace evidence, people exposed, hazard mechanism and applicable duty before selecting a control.
Concept 2
Build the system from the task hazards and interfaces, then make the safe method usable and supervised.
Exam cue: Prefer elimination and engineered or collective protection before procedural controls and PPE, then verify effectiveness.
Concept 3
A generic procedure copied from another task is not proof of a safe system.
