Topic module

Hierarchy of Prevention and Collective Control

Removing hazards where possible and preferring reliable source and collective controls before individual protection.

Long-form learning

Concept to Risk to Memory to Check-up

Move from management ownership to a specific workplace risk assessment, proportionate control, investigation and evidence-led improvement.

Core concepts

Concept 1

Elimination and substitution act earlier than controls that rely on repeated human behaviour.

Exam cue: Ask first whether the activity, material or exposure can be removed.

Concept 2

Engineering and collective measures protect more people without depending on perfect individual action.

Exam cue: Prefer a control that protects everyone at source over one that only warns or equips an individual.

Concept 3

Administrative controls and PPE manage residual risk but are usually less reliable alone.

Risk pitfalls and guardrails

Jumping directly to training or PPE.

Guardrail: Do not replace a design, engineering or organisational control with paperwork, a warning or PPE alone.

Calling a warning sign elimination.

Guardrail: Do not replace a design, engineering or organisational control with paperwork, a warning or PPE alone.

Memory anchors

Eliminate First

Remove the hazard or need for exposure where reasonably practicable.

Substitute Safer

Replace the material, process or equipment with a lower-risk option.

Engineer at Source

Guard, enclose, isolate or ventilate before relying on behaviour.

Collective Before Personal

Protect everyone exposed before depending on individual equipment.

PPE Is Residual

Select, fit, maintain and supervise PPE for risk that remains.

Checkpoint rule

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
