Core concepts
Concept 1
Specified risks, avoidance, atmosphere, isolation, permits, competence, communication and rescue.
Exam cue: Identify the workplace evidence, people exposed, hazard mechanism and applicable duty before selecting a control.
Concept 2
Avoid entry first; if entry is necessary, control energy and atmosphere and establish a credible rescue plan.
Exam cue: Prefer elimination and engineered or collective protection before procedural controls and PPE, then verify effectiveness.
Concept 3
Calling an area confined or issuing PPE does not address the specific hazardous condition.
