Evaluate Controls and Apply Prevention Principles
Likelihood and consequence, existing precautions, avoidance, source control, substitution, collective protection and coherent policy.
How to prepare for both units
Learn the principle, locate scenario or workplace evidence, explain why it matters, recommend proportionate control and show how action will be owned and reviewed.
Core concepts
Concept 1
likelihood and consequence with existing controls
Exam cue: Judge whether installed and procedural controls work in practice, not merely whether they exist.
Concept 2
avoidance, source control and substitution
Exam cue: Prefer removing risk at source before relying on warning, behaviour or response.
Concept 3
collective protection before individual measures
Concept 4
coherent prevention policy and residual risk
Risk pitfalls and guardrails
Treating a policy or installed device as proof of effective control.
Guardrail: Do not answer with unsupported lists, invent a single UK legal regime, confuse the 24-hour FSC1 window with working time, treat the FSC2 three-hour recommendation as a limit or present internal allocations as NEBOSH weights.
Adding isolated precautions that conflict with the overall fire strategy.

Memory anchors
Evaluate actual control
Condition, testing, behaviour and records show whether a precaution works.
Avoid before protect
Remove or reduce risk at source where reasonably practicable.
Collective before individual
Measures protecting everyone take priority over controls dependent on each person.
Controls form a system
Prevention, detection, escape, response and management must operate coherently.
Residual risk drives action
Priorities follow the risk that remains after current precautions are considered.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
